What we look at shapes our desires. What you allow yourself to look upon will either illuminate your soul with divine light, or fill you with spiritual darkness. In Scripture the eyes are more than physical organs—they’re the gateway to the soul, especially the imagination, memory, and desire. The more you look at something, the more your will is drawn to it—whether it’s holy or sinful. St. Augustine said, “The eyes are the scouts of the heart.” They go out and bring back what the heart will begin to desire. If you look at or think on impure or vain things, your heart becomes disordered; if you look at holy, good, and virtuous things, your heart is lifted toward God. We all need to intentionally govern what we allow into our soul through our eyes and our mind’s eye, because every gaze is either strengthening us or weakening us and our very lives. Modern neuroscience research shows that giving in to lower impulses (such as pornography) has lasting effects of weakening the brain’s capacity for reason, restraint, and moral judgment, actually eroding intelligence, not just morally, but neurologically. Achieving a clean eye is essential for manhood and the information on this page is to be taken as the absolute baseline, beginning with:
“Custody of the Eyes”
This means choosing not to look at things (even in your mind) that can lead you to sin, especially lust. It’s not just about avoiding obvious things like pornography, but also being careful with what you watch, read, or where you go and what you linger on in public. It’s about using your eyes to honor God, not fuel temptation.
Be thoughtful about the music, entertainment, social media, and clothing choices you make. The goal isn’t just personal purity but also not causing others to stumble. Dressing and behaving modestly helps protect both your soul and the souls of others from unnecessary temptation.
Train your mind and heart to Look on God and love what’s good and pure. This involves regular prayer and exercising self-control, including consistently saying “no” to harmful thoughts or desires. This Spiritual fitness strengthens your will and keeps your imagination focused on things that help you grow in Strength and Sanctity.
“When the soul reaches the union with God in love, it lives in God and gazes upon Him with the purity and clarity He bestows.”
“The soul that is united with God is feared by the devil as though it were God Himself.”
— Spiritual Canticle
“Gaze upon Him, consider Him, contemplate Him, as you desire to imitate Him.”
“To look upon God is to be saved. Life consists in drawing near to God, and in this consists the vision of God.”
— The Life of Moses
He emphasizes that gazing upon God is the goal of the spiritual journey.
Whether we’re conscious of it or not, every time we choose to look at something, we’re forming habits and shaping our heart. If we constantly look at holy, good, or virtuous things, our soul becomes more disposed to purity and love of God. But if we gaze at things that stir up lust, greed, vanity, or bitterness, we’re making a covenant with disorder and sin.
The “covenant” is what we allow our senses to feed our soul.
Just as Job chose not to look lustfully, we are called to make a similar commitment.
The images and thoughts you allow in shape the memory, which becomes the material the mind and imagination work with.
What we look at forms what we desire, shapes how we think, influences how and what we love, and ultimately affects the state of our soul. To gaze on holy things is to invite God into the soul. To gaze on impure or disordered things is to cloud the soul, darken the intellect, and resist grace.
Exposure to sinful or vain images dims the light of grace, dulls the conscience, and weakens the desire for God.
St. John of the Cross warns that the senses, if not governed, can draw the soul away from God and trap it in attachment and confusion.
Experienced exorcists confirm that visual exposure to evil or impure things gives demons legal access to afflict the soul, because it signals the will’s consent to sin.
A renowned exorcist, Fr. Chad Ripperger emphasizes that spiritual discipline over the senses, especially the eyes, is crucial to protecting oneself from demonic influence. By making a deliberate “covenant” with our eyes—choosing not to look at what leads to sin—we reclaim spiritual dominion over our bodies and keep our soul in a state of grace. Practical examples would include:
If you walk into a store and your eyes unintentionally see immodest images, but you instantly turn away and say a short prayer—you’ve just lived out Job’s covenant.
If you refuse to watch entertainment that contains impure material, you’re saying with your actions: “I won’t make a covenant with these images—I choose the light.”
The eye is often chosen to represent a clean mind, body, and soul because it symbolizes spiritual perception and inner purity. In Scripture, Christ says, “The eye is the lamp of the body. If your eye is sound, your whole body will be full of light” (Matthew 6:22), indicating that the clarity of one’s spiritual vision reflects the state of the whole person. A pure eye symbolizes a heart undivided by sin, attentive to God, and faithful to grace—traits essential for sanctification and union with the divine. The Fathers and Saints, such as St. Augustine, interpret the “sound eye” as a pure intention and heart focused solely on God. Hence, the eye is at the center of the “Gateway Guards” insignia, which is one of the triangular elements of the -M-Power Pyramid.
Custom training program for -M-Powermen designed using the top-level synopsis of Independent Integration Systems Engineering (XSE). The Training Triangle serves as the foundation of the -M-Powermen Pyramid. A man wearing this insignia is actively an -M-Powerman.
The XSE Peak contains all 40 factors involved in Independent Integration Systems Engineering (XSE). Those who are certified to have mastered XSE are known as Pilot Systems Engineers of XSE and may be seen wearing the insignia of the XSE coat of arms (shown below).
Once a person has achieved the clean eye, this state still requires work as it must be maintained and guarded. A man wearing this insignia is dedicated to guarding that which is sacred. Below is a variation of the Gateway guards insignia overlayed on the training triangle.
The Badge of Courage is reserved for men who exult the Holy Cross. A man wearing the Badge of Courage forms his identity in Christ and embraces the Cross with masterly self-discipline. This is the highest -M-Powermen level, requiring the 3 previous insignias as prerequisites.
The -M-Powermen Training Triangle forms the foundation of the -M-Power Pyramid. Built on top of this foundation are the other three triangular elements: the XSE Peak, the Gateway Guards, and the Badge of Courage, all of which are built on top of the previous in order to achieve the next level of -M-Powermen.
The mind’s eye—meaning your imagination, memory, and interior thoughts—is just as important, and sometimes even more dangerous than the physical eye when it comes to sin and holiness.
Here’s why:
Even if you physically avoid sinful sights, the imagination can replay images or situations from the past, or even invent new ones. This is especially true for people struggling with past sins or temptations. Lust, envy, pride, revenge, and vanity can all take root in the imagination if left unchecked.
St. Teresa of Ávila warned that the imagination can be like a “madwoman in the house,” stirring up distractions and illusions if it’s not brought under control.
demons often try to use the imagination to tempt, accuse, or distract—especially during prayer.
When Jesus says: “Anyone who looks at a woman with lust has already committed adultery in his heart” (Matthew 5:28), He’s not just talking about the physical look, but the interior gaze—the possibility of mental indulgence or desire, even if nothing is seen outwardly.
This includes fantasies, memories, thoughts, or entertaining sinful ideas in the “mind’s eye.”
Just like Job made a covenant with his physical eyes, we are called to discipline the imagination:
Don’t accept fantasies, grudges, or other sin.
Don’t replay old sins or imagine scenarios of impurity, pride, or revenge.
Instead, fill your imagination with sacred things—Scripture scenes, lives of the saints, or holy meditations.
This is why many saints recommend mental prayer and Lectio Divina—to train the imagination to dwell on the truths of God, and to turn away from and reject the masks and lies of temptation.
Reject and replace: If a sinful thought or image enters your mind, immediately reject it and replace it with a holy image and/or a short prayer.
Guard what you allow in: What you see, read, and hear influences what your imagination will later recall.
Pray for the purification of memory and imagination, asking the Holy Spirit to sanctify your inner life.
the covenant with the eyes extends to the mind’s eye—what you mentally look at—not just the physical eyes. True freedom and purity comes when both the senses and the imagination are under the authority of Christ and desire only that which is good, never leaving an opening for desiring anything contrary to God or His ways.
The most direct and powerful biblical passage that speaks of the eye as the “window” or “lamp” of the soul comes from Jesus Himself:
“Your eye is the lamp of your body. When your eye is healthy, your whole body is full of light… Therefore be careful that the light in you is not darkness.” – Luke 11:34-36
This teaching shows that what you allow yourself to gaze upon will either illuminate your soul with divine light, or fill you with spiritual darkness. Jesus uses the “eye” as a metaphor for the inner orientation of the soul — “Eye” here symbolizes your inner perception—how you view the world, others, and God. A “sound eye” means a pure, clear, single-hearted gaze, illuminating your entire being. A “bad eye” (corrupted intention or focus) spreads darkness throughout your soul. Jesus emphasizes the spiritual responsibility of maintaining inner clarity to avoid inner darkness.
| Term | Meaning |
|---|---|
| “Eye” | The interior vision or spiritual perception — how we look at the world, others, and God. |
| “Lamp of the body” | Our inner gaze guides the whole person — if it’s pure, our life is lit with truth; if it’s corrupt, we are darkened within. |
2 Corinthians 4:4 is another deeply theological verse that unveils the spiritual battle for the human soul and the mystery of spiritual blindness:
“In their case the god of this world has blinded the minds of the unbelievers, to keep them from seeing the light of the gospel of the glory of Christ, who is the image of God.”
St. Paul refers here to Satan as the (lowercase) “god of this world” (Greek: ho theos tou aiōnos toutou). This doesn’t mean Satan is divine, but rather that he exercises illicit influence over fallen human systems, values, and ideologies.
St. John also says “the whole world lies in the power of the evil one” (1 John 5:19).
Satan presents false lights—pleasure, pride, ambition, relativism—that compete with the light of Christ.
A renowned exorcist notes that Satan’s power is primarily one of deception, not authority. He blinds by promoting error, confusion, and attachments to worldly things.
This is not bodily blindness—it is the intellect darkened and the will weakened due to sin, pride, or rejection of grace.
The mind (Greek: noēma) is where one grasps truth. If the mind is blinded, one cannot perceive spiritual realities.
This is the same concept seen in Romans 1:21–22, where those who reject God “became futile in their thinking” and their “foolish hearts were darkened.”
The “light” here is not just information—it is the divine radiance of truth and grace revealed in Christ.
St. Thomas Aquinas teaches that the Gospel is luminous with divine truth, but only the pure of heart can receive it fully (cf. Matthew 5:8).
Satan’s aim is to obscure this light by promoting falsehood, distraction, or despair, especially through sin, error, and pride.
The Gospel is glorious precisely because it reveals Christ, the visible Image of the invisible God (cf. Colossians 1:15).
To reject the Gospel is to reject not just a message, but a Person—Jesus Christ, who alone reveals the Father.
The enemy’s ultimate strategy is to prevent souls from beholding Christ, because to see Him is to love and be transformed (cf. 2 Corinthians 3:18).
This verse is a wake-up call:
Unbelievers are not merely uninformed; they are blinded by spiritual forces.
We must pray for illumination and conversion—because only grace can remove the veil (2 Corinthians 3:16).
We must also guard ourselves: even believers can be spiritually dulled by sin, worldliness, or pride.
The late Chief Exorcist of Rome, Fr. Amorth, frequently emphasized that spiritual blindness is one of the devil’s most effective tools—fooling people into: not recognizing sin, rejecting the sacraments, or denying Christ’s authority.
“The spirit of man is the lamp of the Lord, searching all his innermost parts.” – Proverbs 20:27
Here, the spirit (akin to the “inner eye”) is what God uses to examine and know your deepest self.
“Turn my eyes from looking at vanities; give me life in your ways.” -Psalm 119:37
Here’s a detailed, well-supported exploration of how giving in to instinctive impulses—especially through pornography use—can undermine intelligence by impairing the prefrontal cortex, the brain’s executive center:
The amygdala and hippocampus drive emotional reactions and reward-seeking behavior—fast, instinctual responses.
The prefrontal cortex—especially the dorsolateral (DLPFC) and ventromedial (vmPFC) areas—is responsible for planning, rational decision-making, self-control, moral judgement, and problem-solving.
When lower, emotion-driven circuits dominate, the PFC becomes underutilized, which models a kind of neural imbalance akin to “juvenilization.” When we indulge emotional reactions, the prefrontal cortex is diminished, and behavior becomes driven by instinct pubmed.ncbi.nlm.nih.gov+15en.wikipedia.org+15covenanteyes.com+15.
The distinction between emotion-driven and reason-driven brain systems is a foundational concept in cognitive neuroscience. It reflects the tension between the limbic system (e.g., amygdala, hippocampus) and the prefrontal cortex (particularly the dorsolateral prefrontal cortex, or DLPFC), with implications for decision-making, impulse control, and moral reasoning.
The amygdala processes emotions, particularly fear and threat; it can trigger rapid behavioral responses before conscious thought.
The hippocampus is involved in emotional memory, context-based decision-making, and reward processing.
The DLPFC is central to executive function, including impulse control, ethical reasoning, and goal-directed behavior.
When emotional stimuli dominate, PFC activity is inhibited, and instinctive, unreflective actions often follow.

These studies form a robust foundation for the “Two-Brain System” model, highlighting how emotion-driven neural systems (limbic) and reason-driven systems (PFC) compete for behavioral control—and how indulging in emotion-driven responses reduces the regulatory role of the dorsolateral prefrontal cortex, impairing moral and rational capacities.
Addiction research describes hypofrontality as a decline in prefrontal activity and blood flow—seen in substance abuse, gambling, and porn use 3en.wikipedia.org+3yourbrainonporn.com+3.
This reduction means brain areas for reason, judgment, and self-regulation are suppressed while impulsive cravings take over.
The concept of hypofrontality—a state marked by reduced activation and blood flow in the prefrontal cortex (PFC)—is widely documented in the context of addiction, gambling disorders, and increasingly in studies on pornography use. This condition leads to impaired executive control, weakened judgment, and dominance of limbic-driven cravings.
Hypofrontality reflects diminished function in the DLPFC, OFC, and ACC—regions crucial for decision-making, impulse suppression, and future planning.
This results in increased compulsivity, impaired self-awareness, and diminished ability to evaluate consequences.
It is consistently observed across substance addiction, behavioral addictions (like gambling), and increasingly pornography-related compulsivity.

These studies provide strong empirical evidence that hypofrontality is a neural signature of addiction, affecting both chemical and behavioral forms—including pornography, gambling, and substance use. The result is reduced capacity for moral reasoning, long-term planning, and impulse inhibition, as the limbic reward system dominates cognitive control.
A JAMA Psychiatry study (Kühn & Gallinat, 2014) found that higher porn use correlated with decreased grey matter volume in reward-related areas (like the caudate) and reduced connectivity between the caudate and DLPFC link.springer.com+5pubmed.ncbi.nlm.nih.gov+5pmc.ncbi.nlm.nih.gov+5.
Further reviews confirm that frequent porn use is linked to lower volume in prefrontal regions (vmPFC, vlPFC, DLPFC) and impaired executive function—reducing self-control, awareness of risk, and ability to inhibit unwanted impulses .
The neurological impact of pornography—particularly its influence on brain structure and executive function—has been increasingly examined through neuroimaging and cognitive neuroscience research. The primary finding: pornography use is associated with reduced grey matter volume in the reward system and weakened connectivity in brain regions responsible for self-control.
Scientific Summary: Pornography’s Neurological EffectsKey areas affected: Caudate nucleus (reward processing), DLPFC/vmPFC (executive function, impulse control), and connectivity pathways between them.

These studies reinforce the concern that repeated exposure to pornography can reshape brain structures and functions involved in decision-making and self-control, making individuals more susceptible to impulsive behavior and executive dysfunction.
According to the Parieto-Frontal Integration Theory (P-FIT), intelligence depends on integrated brain networks, especially those involving frontal and parietal regions.
Grey matter volume and connectivity in the PFC are directly correlated with reasoning ability
Thus, when porn use shrinks or disconnects these PFC regions, a person’s capacity for intelligent thought—problem-solving, planning, moral reflection—is neurologically compromised.
There is growing neuroscientific evidence that executive intelligence—the brain’s ability to reason, plan, and reflect—is deeply dependent on frontal-parietal integration, particularly the prefrontal cortex (PFC). The Parieto-Frontal Integration Theory (P-FIT) asserts that intelligence arises from the efficient communication and grey matter integrity between parietal and prefrontal regions. When these areas are impaired (e.g., due to neuroplastic changes from habitual pornography use), the neural basis of intelligence itself is weakened.
Scientific Foundations: P-FIT and Intellectual FunctionKey regions: Dorsolateral PFC, inferior parietal lobule, anterior cingulate cortex, and connections between them.
Functions: Complex problem-solving, abstract reasoning, impulse regulation, moral cognition, and sustained attention.
Grey matter volume and functional connectivity in these regions strongly predict IQ and executive function.
Disruptions to this system (e.g., chronic overstimulation by porn or digital content) may compromise these capacities.

These sources clearly show that the grey matter volume and connectivity within the P-FIT-defined brain areas are essential for intelligence, and that pornography consumption can alter these structures and functions, potentially compromising reasoning, moral insight, and planning—the neurological foundation of intelligent thought.
Users with pornography problems exhibit more impulsivity, reduced working memory, and executive function challenges, especially when sexual cues are present en.wikipedia.org+3frontiersin.org+3en.wikipedia.org+3.
This shift signals a moment-to-moment surrender of reasoning capacity to emotional triggers—a defense of lower desires over higher faculties.
The behavioral evidence surrounding pornography use and cognitive impairments strongly supports what neuroimaging has already revealed: individuals with pornography problems consistently demonstrate elevated impulsivity, impaired working memory, and weakened executive function, particularly when exposed to sexual cues. This reflects a real-time compromise of rational faculties in favor of emotionally driven behaviors, confirming the limbic override of prefrontal control.
Sexual cues intensify reactivity in the reward system (especially striatum and amygdala), and this reactivity impairs the DLPFC’s ability to regulate decision-making.
Behavioral studies show increased risk-taking, shorter attention spans, and reduced delay discounting in those reporting compulsive pornography use.
This shift reflects a “moment-to-moment” override of reason by emotion, confirming limbic dominance and executive decline.

These studies collectively confirm that problematic pornography use leads to consistent behavioral deficits, particularly under conditions of sexual cue exposure—manifesting as reduced cognitive inhibition, increased impulsivity, and executive dysfunction, validating the real-time erosion of rational self-governance.
Intelligent thought relies on integration between the dorsolateral prefrontal cortex (DLPFC) and parietal lobes, constituting the backbone of reasoning, planning, and working memory—core components of human intelligence .
Habitual impulsivity or emotional reactivity undermines this network. Neuroimaging shows that reduced volume or activity in DLPFC and parietal regions correlates with impulsive behavior and diminished executive control, making the brain increasingly reactive and less rational.
Here are peer-reviewed studies and academic references supporting the statement that habitual indulgence in pornography and similar behaviors leads to hypofrontality, impairing the prefrontal cortex, which is critical for reason, self-control, and moral judgment. These findings suggest a long-term neurological erosion of executive and moral capacities:

These studies form a compelling body of evidence that habitual engagement with pornography can rewire the brain—dampening the prefrontal cortex responsible for executive control, reasoning, and moral decision-making. This hypofrontality fosters impulsivity and emotional dominance over rational reflection, weakening the neural architecture that supports intelligence and character.
The OFC, especially its lateral component, is essential for evaluating the true value of rewards and adjusting behavior based on changing consequences.
Addictive or impulsive actions promote OFC dysfunction, leading to poor decision-making, impulsivity, and emotional dysregulation frontiersin.org+14en.wikipedia.org+14en.wikipedia.org+14.
The OFC’s deterioration fosters short-sighted decisions driven by immediate gratification, further bypassing rational thought.
The ACC monitors conflicts, errors, and risk. Under repeated impulsive behavior, ACC activity drops—meaning less self-awareness of wrong actions and lower motivation to correct behavior .
This weakening erodes the mind’s ability to detect inconsistencies, reflect, and change course.
Here are several studies and references that delve into the role of the anterior cingulate cortex (ACC) in self-awareness, error detection, and impulse control, particularly highlighting how blunted ACC function may contribute to reduced conflict monitoring and emotional dysregulation:
The anterior cingulate cortex (ACC) is crucial for detecting conflict, errors, and monitoring behavioral outcomes.
In cases of impulsivity or addiction, ACC function diminishes, reducing self-awareness and error correction abilities.
This dysfunction leads to an inability to detect mistakes or adapt behavior, contributing to impulsive, short-sighted actions driven by immediate gratification.

These studies indicate that diminished ACC function is central to self-awareness deficits and impulsivity, particularly in addiction and compulsive behavior. The ACC‘s failure to detect errors and conflicts undermines behavioral correction, leading to repeated mistakes, emotional dysregulation, and a failure to adjust behavior. This erosion of self-monitoring may contribute significantly to the persistence of maladaptive behaviors.
The anterior insula processes internal bodily sensations and emotions. In addiction, it becomes hyper-sensitive to cravings and emotional “urges,” strengthening the sympathetic “need‐state,” and further weakening control via ACC and PFC
Here are several studies and references on the role of the anterior insula (AI) in addiction, craving, and emotional dysregulation, showing how its hyperactivity in addiction strengthens emotional urges while weakening the regulatory control provided by the ACC and PFC:
The anterior insula (AI) is involved in processing bodily sensations and emotion regulation, particularly when it comes to craving and impulsivity.
In addictive behaviors, the insula becomes hyper-responsive to emotional stimuli, reinforcing cravings and impulsive urges.
This heightened activity in the insula disrupts cognitive control by the ACC and PFC, weakening the brain’s ability to correct behavior or reflect on long-term consequences.

These studies highlight that the anterior insula is key in craving, impulsivity, and emotional dysregulation in addiction. Hyperactivity in the insula strengthens emotional urges and cravings, which weakens the regulatory functions of the PFC and ACC, thus impairing the brain’s ability to control impulsive behavior and correct maladaptive actions.
Frequent pleasure-seeking sensitizes subcortical structures:
Nucleus accumbens (striatum) becomes hyper-reactive to rewards.
Amygdala–hippocampus–OFC circuits consolidate memory and emotional context tied to reward—deepening habitual behavior
Dopaminergic changes decrease inhibitory control and lower thresholds for gratification .
Here are more studies and citations related to reward network hijacking, specifically how structures like the nucleus accumbens (NAc), striatum, amygdala, and orbitofrontal cortex (OFC) contribute to sensitization, impulsivity, and lowered thresholds for gratification due to dopaminergic changes:
Nucleus Accumbens (Striatum) becomes hyper-reactive to rewarding stimuli in addictive behaviors, enhancing craving and impulsivity.
The Amygdala, Hippocampus, and OFC form circuits that link memory and emotion to reward, reinforcing habitual behavior and emotional responses tied to gratification.
Dopaminergic changes reduce inhibitory control, lowering the thresholds for pleasure and making impulsive decisions more likely.

These studies illustrate the complex role of the reward network—particularly the nucleus accumbens, amygdala, hippocampus, and OFC—in addiction. These structures become sensitized over time, leading to hyper-reactivity to rewards and a decreased threshold for gratification. Dopaminergic changes facilitate this process, making it difficult for individuals to resist impulsive desires, further reinforcing habitual, compulsive behaviors.
With executive, evaluative, and motivational regions weakened, individuals under impulsive habits fall into cognitive dissonance—justifying behavior to align with desires instead of truth.
The limbic and reward systems overshadow logic and self-reflection.
The brain restructures itself to avoid discomfort, reinforcing denial and a distorted inner reality.
Here are several studies and citations on cognitive dissonance and denial in relation to impulsive behaviors, limbic system activation, and how these lead to distorted self-reflection and behavioral justification:
Cognitive dissonance arises when impulsive behavior conflicts with long-term values, triggering justification mechanisms.
The limbic system and reward centers (e.g., nucleus accumbens, amygdala) override the PFC and ACC, suppressing reflection and promoting denial and justification of the behavior.
As a result, self-awareness and evaluative functions (e.g., error monitoring) are diminished, reinforcing distorted beliefs and continuing harmful habits.

These studies show how cognitive dissonance and denial are central to maintaining impulsive behaviors, particularly in situations where reward systems override executive control. As impulsivity and reward-seeking behaviors strengthen the limbic system and reduce self-reflection, individuals restructure their beliefs and behaviors to align with immediate gratification, reducing discomfort and distorting reality.
Structural harm: Research shows reduced volume in DLPFC, parietal cortex, OFC, and ACC .
Functional impairment: Decreased connectivity and activity in networks governing reasoning and moral judgment pmc.ncbi.nlm.nih.gov+15pmc.ncbi.nlm.nih.gov+15digitalcommons.morris.umn.edu+15.
Behavioral evidence: Increased impulsivity, poor decision-making, lack of self-insight, and emotional hijacking.
Frequent impulsive behavior, including seeking pleasure or escape, physically rewires the brain—impairing intelligence by weakening the very regions responsible for rational, self-controlled, and moral cognition.
The good news: due to neuroplasticity, this damage is recoverable. Through disciplined practice—mental training, spiritual formation, sacraments, therapy, and purposeful living—these brain networks can be healed and rebuilt.
Repeated surrender to lower instincts—like pornography—leads to hypofrontality, weakening the very brain regions essential for reason, self-control, and moral discernment. Over time, this erodes the foundation of intelligence itself.
Living in denial of reality—or “pretending” that something isn’t sinful, harmful, or real—is not just a moral or spiritual issue. Scientifically, it correlates closely with the neurological weakening of the prefrontal cortex caused by indulgence in disordered desires like pornography or impulsive gratification.
A “Sound” Eye (Healthy, Single, Pure)
Seeks God above all.
Views the world with clarity, truth, charity.
Leads to spiritual light, inner peace, and holiness.
A “Bad” Eye (Impure, Divided, Envious, Lustful)
Is distracted, prideful, greedy, lustful, or cynical.
Sees others as objects or threats.
Leads to spiritual confusion, darkness, and sin.
St. John Chrysostom:
“The eye signifies the intention of the soul. If it is clear and simple, then the body — that is, the actions — are full of light.”
St. Augustine:
“When the eye is evil, man sees nothing rightly; he is blind to the beauty of God and to the needs of others.”
The “eye” refers to more than physical sight—it’s your spiritual and moral vision.
A single, focused gaze on God and truth fills the soul with light; a divided, impure gaze leads to spiritual fragmentation and moral confusion.
“Blessed are the pure of heart, for they shall see God.” — Matthew 5:8
“The ‘pure in heart’ are promised that they will see God face to face. It is the purity of heart, the faith and love that radiate from the ‘eye’ of the soul, that allows this vision.” -CCC2519
| Image | Meaning |
|---|---|
| “Eye is the lamp” | Your interior gaze determines your spiritual health. |
| Light in you is darkness | A corrupted vision clouds the soul and leads away from God. |
| Sound eye | Sees with faith, purity, charity — brings life and clarity. |
| Bad eye | Sees with envy, lust, pride — spreads darkness and sin. |
A person with an “unclean eye” — meaning a distorted or impure way of seeing — loses their ability to perceive truth.
This inner blindness leads to a kind of pretend life, governed not by what is real, but by illusions, self-deception, or sin.
And tragically, this blindness does not excuse one from judgment, because God sees the heart and calls all to repentance and truth.
The “eye” symbolizes how you look at the world — your values, intentions, moral outlook.
A clean eye sees clearly — the truth of God, the dignity of others, and the path of virtue.
A dirty eye (distorted by sin, pride, lust, envy, or fear) blinds the soul — making sin seem good, or holiness seem foolish.
Jesus’ statement about removing the wooden beam from your own eye before attempting to remove the splinter from your brother’s (Matthew 7:3–5) relates closely to His teaching that “The eye is the lamp of the body. So, if your eye is sound, your whole body will be full of light; but if your eye is bad, your whole body will be full of darkness. If then the light in you is darkness, how great is the darkness!” (Matthew 6:22–23, RSVCE). These two teachings are connected in their emphasis on internal clarity, purity, and moral integrity as the foundation for righteous action and true judgment.
In Matthew 6:22–23, the “eye” symbolizes one’s moral and spiritual perception. A “sound” (Greek: haplous, meaning clear or single-minded) eye leads to a body “full of light,” indicating purity of heart and orientation toward God. A “bad” or “evil” (Greek: ponēros) eye leads to darkness—sin, confusion, and moral blindness.
In Matthew 7:3–5, Jesus condemns the hypocrisy of judging others while ignoring one’s own greater sins. The “beam” in one’s eye obstructs clear moral vision—just as a diseased or darkened eye fails to let in light. This hypocrisy is not merely unjust; it reflects a lack of true self-awareness and a heart not purified by grace.
St. Augustine, in his Sermons, ties both teachings to self-examination and purification. He explains that one must correct his own faults through repentance and grace before he can truly see to correct others. Similarly, St. John Chrysostom emphasizes that the one who sees clearly (whose eye is sound) is able to guide others—not through condemnation, but through charity and truth.
Exorcists stress the importance of internal order and freedom from sin in the exercise of authority or judgment. A person spiritually disordered (with a beam in his eye) lacks the clarity to guide or assist others effectively, echoing Christ’s imagery.
Personal Purity Before Apostolic Mission: You cannot lead others to holiness unless your own eye is purified—meaning your will and intellect are rightly ordered to God.
Discernment: A person with an impure or selfish heart will judge wrongly—either harshly or permissively. The sound eye sees the truth of things in God’s light.
Fraternal Correction: Only someone with a “clear eye” (spiritually purified) can carry out the work of correcting others with humility, truth, and love.
In summary, both passages call for inner purification as the necessary condition for true spiritual sight and right judgment. The “eye” is both the instrument and symbol of our interior moral state—if it is clouded by sin (like a beam), it not only blinds us but also misguides others.
Living in denial of reality—or “pretending” that something isn’t sinful, harmful, or real—is not just a moral or spiritual issue. Scientifically, it correlates closely with the neurological weakening of the prefrontal cortex caused by repeated indulgence in disordered desires like pornography or impulsive gratification. The research demonstrating the science behind this reality is already immense.
The prefrontal cortex (PFC)—especially the dorsolateral (DLPFC) and ventromedial (vmPFC) areas—governs self-reflection, moral reasoning, and the ability to perceive truth and consequences.
The assertion that the prefrontal cortex (PFC)—especially its dorsolateral (DLPFC) and ventromedial (vmPFC) subregions—is central to self-awareness, moral reasoning, truth evaluation, and the regulation of impulses is well-supported by numerous neuroscientific studies. Here’s a synthesis of current findings followed by citations of key studies:
Summary of FindingsSelf-Reflection & Self-Awareness: The DLPFC and medial PFC support introspection and self-representation. vmPFC is implicated in personal value assessments and autobiographical reflection.
Moral Reasoning: Both DLPFC and vmPFC are critical in moral judgment. DLPFC is more engaged during utilitarian reasoning (weighing consequences), while vmPFC is associated with intuitive/emotion-driven judgments.
Truth Perception & Decision-Making: vmPFC activity supports truth-evaluation and suppresses short-term impulses. DLPFC regulates working memory to compare present actions with long-term values.
Behavioral Inhibition: PFC enables the ability to say, “That’s not good for me, therefore I’m not open to it or open to finding it pleasurable.” by managing the tension between impulse and reason.

These studies collectively affirm that the DLPFC and vmPFC work in tandem to monitor behavior, evaluate moral conflicts, resist temptation, and regulate thoughts aligned with truth, consequence, and long-term goals—validating the statement.
In states of hypofrontality—caused by addictions or repeated yielding to base impulses—this higher brain function is impaired.
The result is a neurobiological bias toward immediate pleasure, at the cost of long-term truth, clarity, and rational thought.
This is why a person deep in addictive or compulsive behavior will often:
Rationalize or justify sin
Minimize consequences
Avoid reflection or self-awareness
These are neuropsychological symptoms of a weakened truth-processing center.
The statement connecting hypofrontality, addiction, and impairments in self-awareness, rationality, and moral judgment is grounded in neurobiological research. Studies consistently show that dysfunction in the prefrontal cortex (PFC)—especially under conditions of addiction—leads to deficits in truth-processing, impulse control, denial behaviors, and justification of harmful actions.
Hypofrontality refers to reduced activity in the dorsolateral and medial prefrontal cortex, impairing executive functions like judgment, foresight, and self-monitoring.
This condition is widely observed in substance use disorders, compulsive behaviors, and addictive states, where individuals:
Show denial and rationalization of their behaviors,
Diminish awareness of negative consequences,
Lack emotional insight and self-reflective capacity.
This breakdown in cortical oversight allows the limbic system (emotions, cravings) to dominate over reason.

These studies collectively demonstrate that addictive and compulsive behavior often coexists with hypofrontality, producing neuropsychological states of denial, rationalization, and impaired moral reasoning—essentially compromising the brain’s “truth-processing” functions.
When the PFC is bypassed repeatedly, a person lives primarily from the limbic system (emotion and instinct), not from reason.
This creates a disconnect between reality and perception, where moral truth becomes blurred and subjective.
Scientifically, this mimics what psychologists call cognitive dissonance reduction—changing beliefs to suit behavior, rather than changing behavior to align with truth.
The concept of “living in a constructed false reality” when the prefrontal cortex (PFC) is bypassed in favor of limbic system dominance is well-supported by neuroscience and psychology. This state reflects limbic-driven behavior, impaired rational oversight, and the restructuring of beliefs to justify emotional or impulsive actions—a process known as cognitive dissonance reduction.
Limbic Dominance vs. Prefrontal Oversight:
The limbic system (especially the amygdala) governs emotions, impulses, and fight-or-flight responses.
The PFC, especially the dorsolateral and ventromedial regions, suppresses impulses, evaluates moral standards, and processes reality-based judgments.
When the PFC is weakened (due to trauma, stress, or addictive behaviors), emotional bias overrides factual appraisal.
False Reality Construction:
The absence of PFC regulation leads to perception skewed by emotion, justifying behavior through belief distortion.
This is neurobiologically consistent with cognitive dissonance theory, where individuals unconsciously adjust their beliefs to avoid internal conflict.

These studies reinforce the idea that repeated disengagement of the prefrontal cortex, particularly under emotionally charged or compulsive behavior, results in emotional rationalization, belief distortion, and a constructed subjective reality—mirroring the mechanism of cognitive dissonance reduction.
The repeated choice to indulge a lie (e.g., “This isn’t sinful” or “It’s not harming me”) reinforces the neural path of delusion over truth.
Over time, the brain becomes less capable of recognizing reality, because it has “rewired” to avoid pain, guilt, or discomfort.
The phenomenon where denial becomes neurologically reinforced through repeated avoidance of guilt or truth is a compelling intersection of neuroscience, psychology, and moral cognition. This process reflects how the brain adapts through neuroplasticity to habitual self-deception, moral disengagement, and emotional avoidance, gradually dulling its sensitivity to truth and reality.
Defense Mechanism: Denial is a primitive psychological defense that suppresses awareness of truth to reduce anxiety or guilt.
Neuroplasticity: The brain “learns” to avoid painful insights by reinforcing emotionally rewarding distortions of truth.
Self-Deception: Chronic moral or cognitive dissonance can alter neural pathways—essentially dulling one’s moral and reality-processing capacities over time.
vmPFC & Amygdala: These regions adapt to favor emotional comfort over cognitive or moral integrity, reducing engagement with guilt or reflective judgment.

These works support the claim that denial can be neurologically reinforced through repeated avoidance of discomfort, gradually altering the brain’s sensitivity to truth, guilt, and moral clarity. The result is a biologically and psychologically sustained self-deceptive “false reality.”
Denial of reality is both a symptom and a result of a weakened prefrontal cortex. When a person lives from impulse, avoids the light of truth, and continuously chooses comfort over conviction, their brain literally becomes less capable of reason, awareness, and moral clarity.
This is why both spiritual and neurological healing must involve truth, repentance, and the re-engagement of the rational faculties—through prayer, fasting, self-discipline, and sacramental grace.
Sin doesn’t just offend God and damage our lives—it damages our very ability to reason and think well. This is supported by modern neuroscience research findings. When we yield to emotion-driven behavior (rooted in the amygdala and hippocampus) our prefrontal cortex (the brain center for logic, planning, self-control, moral reasoning and intelligence in general) becomes underused or suppressed. Giving in to impulsive urges (like pornography use) increases the lower brain circuits (making a person more likely to be operated by whims, feelings, and their appetite), while weakening or “shutting down” their ability to reason, problem solve, and exert self-control (associated with the prefrontal cortex).
Studies have shown that pornography viewing correlates with reduced prefrontal cortex activation, diminished executive control (decision-making, impulse regulation), and a shift toward more primitive “juvenile” brain functioning. In other words, the more we indulge lower desires without restraint, the more our intelligence—anchored in higher reasoning and self-control—diminishes.
Sin disorders the soul, and disordered souls do not perceive reality clearly.
Pride makes a person think they are wise, when they are actually blind (Romans 1:22).
The person becomes trapped in a false version of reality, where self justifies sin and avoids truth.
St. John Paul II:
“The more conscience is blinded… the more the individual easily falls prey to self-deception.”
St. Thomas Aquinas:
“Sin darkens the intellect.”
When we act on impulse and gratification, we strengthen those instinctive brain pathways while weakening the brain’s capacity for reason, restraint, and moral judgment. That’s why indulgence in lower impulses actually erodes intelligence, not just morally, but neurologically.
Pretending—whether it’s ignoring sin, downplaying its seriousness, or acting as though we don’t know the truth—does not remove accountability before God, because moral responsibility is based on truth and the will, not on denial or self-deception. To choose not to acknowledge or confront evil is a choice—and in many cases, it reflects chosen ignorance or willed blindness, both of which a person is morally responsible for because they should have known better or could have learned the truth but chose not to. Knowingly avoiding truth or suppressing conscience is itself a sin against the light, and God judges not by our illusional standards, but by the reality of our consent and actions and inactions. Though the person may feel justified by their distorted view, God judges based on truth, not appearances or self-delusion.
Romans 2:5–6:
“By your stubbornness and impenitent heart, you are storing up wrath… God will repay each one according to his deeds.”
God offers grace to every soul — through conscience, truth, and opportunities for conversion. Refusing to see rightly, out of pride or indulgence, is a moral failure — not an excuse.
John 3:19–20 – “Light has come into the world, but people loved darkness… for everyone who does evil hates the light.”
Proverbs 4:25 – “Let your eyes look directly forward, and your gaze be straight before you.”
Ecclesiastes 2:10–11 – The eye can be drawn to vanity and pleasure, which proves ultimately unsatisfying.
Living in illusion when a person sins means choosing to believe or act as though something false is true—denying the reality of God’s law, the consequences of sin, or one’s dependence on grace. Sin distorts the intellect and weakens the will, leading the soul to embrace deception over truth. As St. Thomas Aquinas explains, sin darkens the intellect, making the sinner blind to divine truth. This illusion creates a false sense of freedom or happiness, while in reality, it leads to bondage and separation from God.
1 Samuel 16:7 – “For the Lord sees not as man sees: man looks on the outward appearance, but the Lord looks on the heart.”
Proverbs 21:2 – “Every way of a man is right in his own eyes, but the Lord weighs the heart.”
This is what the saints call living in illusion — and it leaves the soul vulnerable to demonic suggestion, despair, and ultimately, damnation if not corrected.
Isaiah 6:9–10 – “…‘Hear and hear, but do not understand; see and see, but do not perceive.’ Make the heart of this people dull…”
The person who does not have a clean eye lives in shadows, and thus cannot grow, repent, or be sanctified. They live a false life, filled with vain goals, deceptive peace, and fruitless suffering.
| Condition | Consequence |
|---|---|
| Dirty Eye (impure vision) | Confuses right and wrong, distorts truth |
| False Reality | Person lives in illusion, justifying sin |
| Loss of Clarity | Cannot discern God’s will or true love |
| Judgment Remains | Self-deception does not excuse accountability |
| Only Grace Restores Vision | Through humility, repentance, and faith |
The good news is that Christ came to restore sight to the blind — physically and spiritually.
A soul that turns to God in humility, repentance, and prayer can be healed — and begin to see clearly again.
Psalm 51:10 – “Create in me a clean heart, O God, and renew a right spirit within me.”
“Lord, let me know myself, let me know You — and I shall see clearly.” -St. Augustine
Psalm 119:18 – “Open my eyes, that I may behold wondrous things out of your law.”
Job speaks of his voluntary discipline and interior commitment in Job 31:1:
“I have made a covenant with my eyes; how then could I gaze at a virgin?”
This powerful verse comes from Job’s extended self-defense, where he asserts his moral integrity and purity before God.
A covenant is a sacred, binding agreement—often used in Scripture to describe one’s relationship with God. Job applies this to his own senses, specifically his eyes, showing that he has chosen voluntarily and intentionally to discipline his vision, which is the gateway to desire.
He is not merely avoiding outward sin; he has bound himself interiorly not to allow his eyes to wander toward impurity.
The “covenant with the eyes” is a form of custody of the senses
This mirrors Jesus’ teaching in Matthew 5:28: “Anyone who looks at a woman with lust has already committed adultery with her in his heart.”
St. Gregory the Great praises Job in his Moralia in Job for showing interior purity as the foundation for true holiness. He notes that controlling the senses is key to controlling the passions.
In order to have virtue and integrity, the senses must be governed by the intellect and will. Making a covenant with the eyes is an act of authority and spiritual warfare, keeping temptation at bay before it takes root.
Matthew 5:29 is one of the more arresting and symbolic teachings of Christ in the Sermon on the Mount:
“If your right eye causes you to sin, tear it out and throw it away; it is better for you to lose one of your members than for your whole body to be thrown into Gehenna.”
This verse comes immediately after Jesus’ teaching on lust and purity of heart, where He says:
“You have heard that it was said, ‘You shall not commit adultery.’ But I say to you that everyone who looks at a woman with lust has already committed adultery with her in his heart.” (Matthew 5:27–28)
Here’s a theological and spiritual unpacking:
Jesus is not advocating physical mutilation. As Origen, Chrysostom, and Augustine teach, Jesus uses hyperbolic language to shock the listener into understanding the seriousness of sin—especially sins that originate in the inner faculties (like lust or envy).
In Scripture, the eye often symbolizes desire, intention, or the way we view the world. If the “eye” leads one into sin, it’s a metaphor for what you allow yourself to look at, focus on, or entertain in your thoughts.
This ties directly to Matthew 6:22, “The eye is the lamp of the body…” A disordered eye fills the body with darkness.
The right eye is emphasized because, culturally, the “right” side represented strength or importance—Jesus is saying: even if it’s something valuable to you, if it leads to sin, it must be cut off.
Jesus is calling for radical interior conversion. It’s not enough to avoid external sin; one must be willing to sever internal attachments and disordered desires—even at great personal cost.
St. Augustine explains this as the need to detach from anything or anyone (even relationships or positions of influence) that tempt you to sin.
St. Thomas Aquinas, in his Catena Aurea, teaches that “eye” and “hand” refer not just to faculties but to persons—even a close friend or beloved habit that causes sin must be renounced.
Jesus contrasts this “sacrifice” with the far worse alternative: eternal separation from God. The stakes are not merely moral betterment—they are heaven or hell. This warning highlights both Christ’s mercy (in showing us the path) and His justice (in warning of the consequences).
In spiritual life, especially in ascetical theology, this verse has been foundational for the practice of:
Custodia oculorum (“custody of the eyes”)—training the senses, especially vision, to avoid sinful occasions.
Interior mortification—the discipline of imagination and thought, not just behavior.
Detachment—cutting off occasions, people, or things that occasion habitual sin.
In order to be liberated one must remove the proximate occasions of sin, particularly those tied to the senses and the will. This is essential to spiritual warfare and liberation.
A person with clean, good, or pure eyes is a sanctified person — because their inner gaze is fixed on God, and their life is being purified and transformed by grace. In biblical theology, the “eye” is not merely physical — it symbolizes how a person sees, values, and desires, which reflects the state of their soul.
The “eye” in some scripture passages refers to the inner vision of the soul:
What do you focus on?
What are your intentions?
What governs your choices and desires?
A pure eye is single-minded, truthful, undivided — it sees through the lens of faith, virtue, and charity.
Sanctification means to be made holy, set apart, and conformed to Christ.
As the soul is purified, the way it “sees” — meaning how it perceives reality, truth, and goodness — becomes aligned with God’s vision.
1 Corinthians 2:16:
“We have the mind of Christ.”
The pure eye of a sanctified person does not look at others with lust, envy, or pride — but with mercy, clarity, and humility.
| Mark of a Pure Eye | Evidence of Sanctification |
|---|---|
| Sees others with mercy | Has charity at heart |
| Desires what is holy | Detachment from worldly passions |
| Perceives truth clearly | Illuminated by grace |
| Stays fixed on God | Oriented to Heaven, not self |
Psalm 119:18:
“Open my eyes, that I may behold wondrous things out of Your law.”
Jesus teaches that when the eye is pure, the whole body is full of light.
This is the image of sanctifying grace filling the person — radiating into all their actions, words, and decisions.
St. Teresa of Ávila:
“The soul in a state of grace is a crystal clear fountain where God reflects Himself.”
The pure in heart — sanctified souls — are those whose inner gaze is clean, undistracted by sin, and fully directed toward God.
Seeing with pure eyes flows from a heart purified by grace, free from mortal sin, and longing for holiness.
The sanctified person lives in the light — and that light touches every part of their being.
A sanctified person is one who is being made into a temple of the Holy Spirit (1 Cor. 6:19), and that sanctification flows outward — including in how they see, judge, desire, and love.
Their “eye” is clean because their heart is clean.
Romans 8:5–6:
“Those who live according to the Spirit set their minds on the things of the Spirit… To set the mind on the Spirit is life and peace.”
A sanctified person’s “eye” is guided by the Holy Spirit — not by the flesh, the world, or vanity.
This spiritual vision guards them from deception, guides their decisions, and keeps their life ordered toward Heaven.
To be a sanctified person means to be made holy — set apart by God, purified by grace, and dedicated to His service.
John 9:39–41 is a profound passage where Jesus delivers a spiritual interpretation of the physical healing of the man born blind:
“Jesus said, ‘For judgment I came into this world, that those who do not see may see, and those who see may become blind.’ Some of the Pharisees near him heard this, and said to him, ‘Are we also blind?’ Jesus said to them, ‘If you were blind, you would have no guilt; but now that you say, “We see,” your guilt remains.’” (John 9:39–41)
This passage contains deep layers of meaning, especially when viewed in the context of the Gospel and the call to sanctification.
Jesus has just healed a man who was blind from birth (John 9:1–38), a sign that reveals both His divine identity and His mission to restore sight—not just physically, but spiritually. The Pharisees, despite their knowledge of the Law, reject Jesus and refuse to believe in the miracle or what it signifies.
This refers to those who acknowledge their blindness—their ignorance, sinfulness, or spiritual need. Like the blind man who receives both physical and spiritual sight (he ends up worshiping Jesus), these are the humble and poor in spirit (cf. Matthew 5:3).
St. Augustine explains that this is the grace of humble receptivity. If one admits they cannot see (i.e., they need salvation), they are open to grace and truth.
Fr. Gabriel Amorth also notes that humility is essential to receiving healing and deliverance from evil—acknowledging our blindness is a first step to freedom.
Those who claim to see—like the Pharisees—believe they already possess all truth and need no correction. Their pride blinds them to grace. Jesus is not making them blind arbitrarily; rather, His coming exposes their inner darkness, and by rejecting Him, they choose blindness.
This is a judgment of revelation—the presence of Christ reveals the true state of every heart.
St. Thomas Aquinas, commenting on this passage, says the Pharisees “judged themselves” by clinging to their false righteousness.
Jesus here makes a sharp distinction:
If the Pharisees were truly ignorant (invincible ignorance), they might be excused.
But because they claim knowledge and moral superiority, they are morally culpable. Their guilt “remains” because they refuse to repent or receive the truth.
Humility opens the eyes of the soul.
Pride, sin, justification and self-righteousness are spiritual blindness.
The “judgment” Jesus brings is not simply condemnation, but a crisis point—a moment of choice, where truth either heals or is rejected.
Sanctification flows from our participation in the life of Christ, especially through the Sacraments, virtue, and the indwelling of the Holy Spirit. Sanctification is the process by which God makes a person holy, transforming them into the image of Christ through grace, virtue, and obedience to His will.
In Baptism, original sin is washed away and the soul receives sanctifying grace — the very life of God.
This marks the beginning of a lifelong transformation into holiness.
“Baptism not only purifies from all sins, but also makes the neophyte a ‘new creature,’ an adopted son of God, who has become a partaker of the divine nature.” -CCC1265
Sanctification is not a one-time event. It continues throughout life as the person cooperates with grace, resists sin, grows in virtue, and conforms more and more to Christ.
Romans 12:2:
“Be transformed by the renewal of your mind, that you may discern what is the will of God — what is good and acceptable and perfect.”
This daily growth is supported by:
Frequent reception of the Eucharist to conform to Christ, purify the inner faculties, and receive supernatural strength against evil. The Eucharist is food for the spiritual battle, arming the soul against temptation, demonic influence, and the pull of the world and the flesh. “Whoever eats my flesh and drinks my blood remains in me, and I in him.” (John 6:56)
Confession for cleansing the soul and healing and to strengthen against future temptations.
Prayer, fasting, and acts of charity as sacrifice. “Prayer joined to sacrifice constitutes the most powerful force in human history.” – St. John Paul II
Sanctification is both active and passive
It is God’s work first—through the Holy Spirit, sacraments, and grace.
But it also requires our cooperation—especially in how we govern our thoughts, desires, and actions.
It is God alone who sanctifies — but He does so through our cooperation.
The Holy Spirit dwells in the soul and forms the person in the likeness of Jesus.
“God chose you… to be saved, through sanctification by the Spirit and belief in the truth.” -2 Thessalonians 2:13
Only the holy can enter Heaven, where nothing unclean exists (Revelation 21:27).
Therefore, sanctification is not optional — it is the very goal of Christian life.
“All Christians… are called to the fullness of Christian life and to the perfection of charity.” -CCC 2013
Saints are those who have reached the fullness of sanctification — either in this life or through final purification (Purgatory).
Sanctification is not merely about avoiding outward sin—it is about the interior transformation of the entire person: body, mind, will, and soul. This means:
The senses (what we see, hear, touch) must be purified and disciplined.
The mind and imagination must be renewed and conformed to the truth of Christ.
The will must be ordered toward God’s will.
As St. Paul says:
“Take every thought captive to obey Christ.” (2 Corinthians 10:5)
This means every mental image, desire, and memory must be subjected to His kingship if we are to be made holy.
“For this is the will of God — your sanctification.”
— 1 Thessalonians 4:3
St. Paul of the Cross:
“Sanctity consists in doing the will of God with a joyful heart.”
The senses and the mind must be brought under the authority of Christ in order for a person to be sanctified.
St. Augustine wrote that the soul must be ruled by God, not by the passions or lower appetites. When the soul submits to Christ, the senses and the intellect fall into proper order.
St. Thomas Aquinas taught that sanctifying grace heals and elevates the soul—but this grace must flow into the faculties of the soul, including the imagination, memory, and senses, so they can serve God rightly.
True spiritual freedom—and sanctification—requires reclaiming interior authority under Christ. This includes:
Renouncing disordered use of the faculties.
Breaking diabolical influence where the soul has ceded ground through sin.
Reestablishing Christ’s kingship over the mind, body, and soul.
Without this, the soul remains fragmented, vulnerable to temptation, and resistant to grace.
Ultimately, sanctification is about being united to Christ so deeply that everything in you—your thoughts, desires, actions—reflects Him.
This cannot happen if parts of the person (like the imagination or the senses) are still ruled by sin, addiction, or spiritual disorder.
Romans 12:2 – “Be transformed by the renewal of your mind…”—a direct command to bring the intellect under grace.
“For this is the will of God — your sanctification.”
— 1 Thessalonians 4:3
St. Paul of the Cross:
“Sanctity consists in doing the will of God with a joyful heart.”
Though governing your senses, memory, intellect, heart, and imagination is a real and necessary part of sanctification, sanctification includes much more: receiving grace, growing in charity, and being conformed to Christ in every part of your being. To be sanctified, every aspect of your being must be brought under the Lordship of Christ. This is both the condition and fruit of sanctification.
Signs and traits of a Sanctified man include:
“Create in me a clean heart, O God, and renew a right spirit within me.” (Psalm 51:10) “Holy Spirit, purify and sanctify me.”
When a sinful image or thought comes to mind:
Reject it immediately: “In the name of Jesus, I reject this thought.”
Replace it: mentally turn to a holy image, a line from Scripture, or the face of Christ.
Invoke the Holy Name or say short prayers like:
“Jesus, Mary, I love You, save souls!”
“Immaculate Heart of Mary, be my purity!”
The eye is chosen to represent a clean mind, body, and soul because it symbolizes spiritual perception and inner purity. The clarity of one’s spiritual vision reflects the state of the whole person. A pure eye symbolizes a heart undivided by sin, attentive to God, and faithful to grace —traits essential for sanctification and union with the divine. Hence, the eye is at the center of the “Gateway Guards” insignia, and those who possess a pure eye are fully aware of its priceless value, and the value of all which is sacred, including human life from conception to natural death, and the sacred relationships that God has ordained on earth. The Guarding of that which is sacred is explained on the “Gateway Guards” page.
