The Armor of God Prayer

When St. Paul wanted to teach the young Church how to stand against the devil, he reached for the equipment of the Roman soldier guarding him: belt, breastplate, shoes, shield, helmet, sword. Ephesians 6:10–18 is the closest thing the New Testament has to a manual of spiritual defense — and Christians have prayed their way through that armor, piece by piece, ever since.

The prayer below walks through each piece of the armor as a morning consecration: truth, righteousness, the readiness of the Gospel of peace, faith, salvation, and the word of God. Pray it slowly — preferably at the start of the day, before the battle finds you. After it, the passage in full, and what each piece means.

Paul’s image is precise, not decorative. Every piece answers a real form of attack. The belt of truth holds everything else together — because the enemy’s native weapon is the lie; Jesus calls the devil “a liar, and the father of lies” (John 8:44). The breastplate of righteousness guards the heart; the shoes of the Gospel of peace keep a soldier moving instead of pinned down; the shield of faith is named as the piece “with which you will be able to quench all the fiery darts of the evil one” (Ephesians 6:16).

Notice what the armor is made of: nothing in the list is a trophy won by effort alone. Truth, righteousness, peace, faith, salvation, the word of God — each one is Christ’s gift, put on rather than produced. That is why the passage begins “be strong in the Lord and in the strength of his might” (Ephesians 6:10). The armor of God is, finally, Christ himself: “put on the Lord Jesus Christ” (Romans 13:14).

And the last weapon in the list is the one Christians most often forget is part of the armor at all: “praying at all times in the Spirit” (Ephesians 6:18). The armor is put on kneeling.

• In the morning, before the day begins — the traditional use.
• Before situations you expect to test you: difficult conversations, temptation, travel.
• With your children — many families pray the armor aloud together before school.
• Whenever fear or spiritual heaviness sets in during the day.

The passage the prayer is built on, in the World English Bible, Catholic Edition. St. Paul was writing from prison — he calls himself “an ambassador in chains” two verses later (Ephesians 6:20) — which may be why the soldier’s kit was so close at hand for him.

Paul did not invent the image. In the Old Testament the armor belongs to God himself, who arms himself to rescue his people. Isaiah says of the Lord: “He put on righteousness as a breastplate, and a helmet of salvation on his head” (Isaiah 59:17), and of the promised king: “Righteousness will be the belt around his waist, and faithfulness the belt around his waist” (Isaiah 11:5). The Book of Wisdom pictures God taking “his zeal as complete armor”: “He will put on righteousness as a breastplate … He will take holiness as an invincible shield” (Wisdom 5:17–19).

The belt of truth. A Roman soldier’s belt held his tunic and his sword in place; without it nothing else stayed on. Truth works the same way in the Christian life. It means holding to the truth of the faith, and it also means being truthful: the Catechism calls truthfulness the virtue “which consists in showing oneself true in deeds and truthful in words, and in guarding against duplicity, dissimulation, and hypocrisy” (CCC 2468). The devil’s first weapon is the lie; a person who does not lie, even to himself, is hard to get a grip on. “Putting away falsehood, speak truth each one with his neighbor” (Ephesians 4:25).

The breastplate of righteousness. The breastplate covers the heart and the vital organs. Righteousness here is first the righteousness God gives, and then a life lived rightly. St. John Chrysostom, preaching on this verse, said: “As the breastplate is impenetrable, so also is righteousness, and by righteousness here he means a life of universal virtue” (Homilies on Ephesians, 24). Among the moral virtues it is closest to justice, “the constant and firm will to give their due to God and neighbor” (CCC 1807).

The shoes of the Good News of peace. A soldier with bad footing cannot stand or move. Paul’s phrase echoes Isaiah: “How beautiful on the mountains are the feet of him who brings good news, who publishes peace” (Isaiah 52:7). The virtue is a readiness to carry Christ’s peace wherever you go: “Peace I leave with you. My peace I give to you” (John 14:27). The Catechism calls peace “the work of justice and the effect of charity” (CCC 2304). The soldier in this armor is, strangely, a peacemaker.

The shield of faith. The Roman infantry shield was large enough to cover most of a man, and arrows tipped with fire were a real weapon of ancient warfare. Paul says faith is what puts out “all the fiery darts of the evil one.” The virtue is faith, the theological virtue “by which we believe in God and believe all that he has said and revealed to us” (CCC 1814). St. Peter gives the same advice about the devil: “Withstand him steadfast in your faith” (1 Peter 5:9).

The helmet of salvation. The helmet protects the head, and so the mind. In 1 Thessalonians Paul calls the helmet “the hope of salvation” (1 Thessalonians 5:8): the virtue is hope, which the Catechism says “keeps man from discouragement” and “sustains him during times of abandonment” (CCC 1818). A mind that knows how the story ends is hard to frighten.

The sword of the Spirit, which is the word of God. The only weapon in the list, and it is Scripture. When Jesus was tempted in the desert he answered each temptation with a verse: “It is written, ‘Man shall not live by bread alone, but by every word that proceeds out of God’s mouth’” (Matthew 4:4). “The word of God is living and active, and sharper than any two-edged sword” (Hebrews 4:12). The Catechism quotes St. Jerome: “Ignorance of the Scriptures is ignorance of Christ” (CCC 133). To take up the sword is to know the Bible well enough to answer a lie with the truth.

After the six pieces Paul adds what holds them together: “with all prayer and requests, praying at all times in the Spirit, and being watchful to this end in all perseverance and requests for all the saints” (Ephesians 6:18). Prayer is not a seventh piece of equipment. It is how the armor is worn.

For mornings when there is no time for the full prayer, one line per piece. Many people pray it while getting dressed, putting on each piece as they put on their clothes.

Parents often pray the armor over their children before school, or over the whole household at night. The simplest way is to pray it in the plural and add names. With small children, make it a game of getting dressed: a belt, a vest, shoes, a shield, a hat, a sword. With teenagers, one piece a day is often more than enough.

The narrated prayer above says “I put on the belt of truth,” and many armor prayers online say the same. It is worth being clear about what that means. Paul’s command is addressed to Christians, and the one who clothes them is God: the armor is “of God.” Saying “I put on the breastplate of righteousness” is a way of accepting what God gives and asking him for it. It is not a formula that makes you safe by being said, and it gives you no power to order evil spirits about.
