Armor has long been seen as more than just physical protection—it is a symbol of virtue, strength, and spiritual resilience. In medieval times, particularly within the ideals of chivalry and knighthood, each piece of armor was thought to represent a moral or spiritual principle. A true knight was not just strong in battle, but fortified in virtue, as their character was seen as essential to their ability to protect and serve honorably. Just as physical armor shields the body from harm, virtues meld together into humility, creating supernatural armor, protecting the soul from temptation, corruption, and moral weakness. This freedom from pride, Humility, is the ability to see oneself honestly and accurately — with all strengths, weaknesses, and limits — without exaggeration or self-deprecation.
St. John of the Cross:
“The soul that is united with God is feared by the devil as though it were God Himself.”
St. John of the Cross is emphasizing a mystical truth: when a soul is deeply united with God through grace and purification, it participates in God’s own holiness and authority. In spiritual combat, the devil perceives not just the human soul, but the divine presence within it.
This aligns with Scripture:
“It is no longer I who live, but Christ who lives in me.”
— Galatians 2:20
When Christ lives in the soul, the devil recoils—not from human strength, but from divine indwelling.
Spiritual Warfare
Exorcists emphasize:
Authority in Christ: The more a soul is united with God, the more authority it has over evil spirits.
State of Grace: The soul in mortal sin loses spiritual authority, while one in grace carries the presence and power of God.
Fear of Holiness: Demons fear holy priests, sacramentals, and especially lay souls in deep union with Christ because they reflect His power and truth.
Fr. Chad Ripperger, a renowned exorcist explicitly says that:
“Demons are terrified of sanctity. They fear the Blessed Virgin not for her power in herself, but because of the grace and perfection she possesses and her union with God.”
This is exactly what St. John of the Cross means: the closer we are to God, the more threatening we are to the kingdom of darkness.
Insights from the late Chief Exorcist of Rome
Fr. Gabriel Amorth, chief exorcist of Rome, writes:
“The devil is afraid of us when we pray and make sacrifices. He is also afraid of us when we are close to God and remain in the state of grace.”
— An Exorcist Tells His Story
He explains that even the mere presence of a saintly person can cause torment to demons during exorcism sessions, because the soul is radiating God’s presence.
Practical Implications for You
Holiness is your armor: Grow in grace through frequent confession, Eucharist, prayer, and detachment from sin.
Don’t fear the devil—make him fear you: Unite your soul to God daily through acts of charity, humility, and purity.
Use your authority wisely: Especially if you are the head of a household or have spiritual responsibilities, your holiness spiritually protects those under your care
