By this holy armor of the Cross Christ the Lord has terminated the omniconsuming bowels of Hades and blocked the many snares in the mouth of the devil. Having seen the Cross, death trembled and released everyone whom she possessed with the first creature. Armed with the Cross, the God-bearing apostles subdued all the power of the enemy and caught all peoples in their dragnets, and gathered them for the worship of the One Crucified. Clothed in the Cross as in armor, the martyrs of Christ trampled all the plans of torturers and preached with plainness the Divine Cross-bearer. Having taken up the Cross for the sake of Christ, those who renounced everything in the world settled in deserts and on mountains, in caves and became the fasters of the earth.
But what language is worthy to praise the Cross, this invincible wall of the Orthodox, this victorious armor of the Heavenly King?! By the cross the Almighty One bestowed unspeakable blessings on humanity!
Therefore on the forehead, and on the eyes, and on the mouth, and on the breasts let us place the life-giving Cross. Let us arm them with the invincible armor of Christians, with this hope of the faithful, with this gentle light. Let us open paradise with this armor, with this support of the Orthodox faith, with this saving praise of the Church. Neither in one hour, nor in one instant, let us not forget the Cross, nor let us begin to do anything without it. But let us sleep, let us arise, let us work, let us eat, let us drink, let us go on our way, let us sail on the seas, let us go across the river, let us adorn all our members with the life-giving Cross. And let us not be frightened 'by the terror of the night, nor by the arrow that flies by day, nor by anything roaming in darkness, nor by any calamity, nor any noonday demon' (Ps. 90:5, 6). If, O Christian, you will always take up the Cross of Christ on yourself as a help, then 'evil shall not come towards you, nor any scourge come near your habitation': for the opposition power seeing it trembles and leaves.
- St. Ephraim the Syrian
