“Let us not then be ashamed to confess the Crucified. Be the Cross our seal made with boldness by our fingers on our brow, and on everything; over the bread we eat, and the cups we drink; in our comings in, and goings out; before our sleep, when we lie down and when we rise up; when we are in the way, and when we are still. Great is that preservative; it is without price, for the sake of the poor; without toil, for the sick; since also its grace is from God. It is the Sign of the faithful, and the dread of devils…”

+ St. Cyril of Jerusalem

“When, then, you make the sign of the cross on the forehead, arm yourself with a saintly boldness, and reinstall your soul in its old liberty; for you are not ignorant that the cross is a prize beyond all price.

Consider what is the price given for your ransom, and you will never more be slave to any man on earth. This reward and ransom is the cross. You should not then, carelessly make the sign on the forehead, but you should impress it on your heart with the love of a fervent faith. Nothing impure will dare to molest you on seeing the weapon, which overcomes all things.”

+ St. John Chrysostom

“Do not do anything without signing yourself with the sign of the Cross! When you depart on a journey, when you begin your work, when you go to study, when you are alone, and when you are with other people, seal yourself with the Holy Cross on your forehead, your body, your chest, your heart, your lips, your eyes, your ears. All of you should be sealed with the sign of Christ’s victory over hell. Then you will no longer be afraid of charms, evil spirits, or sorcery, because these are dissolved by the power of the Cross like wax before fire and like dust before the wind.”

— Elder Cleopa

By the Cross, the Son of God having become man, accomplished our salvation. He humbled Himself and became obedient unto death, even the death of the Cross (Phil. 2:8). Having stretched out His hands upon the Cross, the Saviour with them, as it were, embraced the world, and by His blood shed on it, like a king with red ink, He signed the forgiveness of the human race.

The Cross of the Lord was the instrument by which He saved the world after the fall into sin. Through the Cross, He descended with His soul into hell so as to raise up from it the souls who were awaiting Him. By the Cross, Christ opened the doors of paradise which had been closed after our first ancestors had been banished from it. The Cross was sanctified by the Body of Christ which was nailed to it when He gave Himself over to torments and death for the salvation of the world, and it itself was then filled with life-giving power. By the Cross on Golgotha, the prince of this world was cast out (John 12:31) and an end was put to his authority. The weapon by which he was crushed became the sign of Christ’s victory.

The demonic hosts tremble when they see the Cross, for by the Cross the kingdom of hell was destroyed. They do not dare to draw near to anyone who is guarded by the Cross.

The whole human race, by the death of Christ on the Cross, received deliverance from the authority of the devil, and everyone who makes use of this saving weapon is inaccessible to the demons.

When legions of demons appeared to St. Anthony the Great and other desert-dwellers, they guarded themselves with the Sign of the Cross, and the demons vanished.

When they appeared to Saint Symeon the Stylite, who was standing on his pillar, what seemed to be a chariot to carry him to heaven, the Saint, before mounting it, crossed himself; it disappeared and the enemy, who had hoped to cast down the ascetic from the height of his pillar, was put to shame.

One cannot enumerate all the separate examples of the manifestation of the power of the Cross in various incidents. Invisibly and unceasingly there gushes from it the Divine grace that saves the world.

The Sign of the Cross is made at all the Mysteries and prayers of the Church. With the making of the Sign of the Cross over the bread and wine, they become the Body and Blood of Christ. With the immersion of the Cross, the waters are sanctified. The Sign of the Cross looses us from sins. “When we are guarded by the Cross, we oppose the enemy, not fearing his nets and barking.” Just as the flaming sword in the hands of the Cherubim barred the entrance into paradise of old, so the Cross now acts invisibly in the world, guarding it from perdition.

The Cross is the unconquerable weapon of pious kings in the battle with enemies. Through the apparition of the Cross in the sky, the dominion of Emperor Constantine was confirmed and an end was put to the persecution against the Church. The apparition of the Cross in the sky in Jerusalem in the days of Constantius the Arian proclaimed the victory of Orthodoxy. By the power of the Cross of the Lord, Christian kings reign and will reign until Antichrist, barring his path to power and restraining lawlessness (Saint John Chrysostom, Commentary on 11 Thes. 2:6-7).

The “sign of the Son of Man” (Matt. 24:30), that is, the Cross, will appear in the sky in order to proclaim the end of the present world and the coming of the eternal Kingdom of the Son of God. Then all the tribes of the earth shall weep, because they loved the present age and its lusts, but all who have endured persecution for righteousness and called on the name of the Lord shall rejoice and be glad. The Cross then will save from eternal perdition all who conquered temptations by the Cross, who crucified their flesh with its passions and lusts, and took up their cross and followed their Christ.

But those who hated the Cross of the Lord and did not engrave the Cross in their soul will perish forever. For “the Cross is the preserver of the whole universe, the Cross is the beauty of the Church, the Cross is the might of kings, the Cross is the confirmation of the faithful, the Cross is the glory of angels and the scourge of demons” (Monday Matins).

— St. John Maximovitch

The devil is afraid of us when we pray and make sacrifices. He is also afraid when we are humble and good. He is especially afraid when we love Jesus very much. He runs away when we make the Sign of the Cross.

+ St. Anthony the Great
