Come, ye faithful, let us bow down before the life-creating Tree, whereon of His own will Christ, the King of glory, stretching forth His hands, hath raised us up to our former blessed state, of which the enemy of old deprived us through pleasure, causing us to be driven out of paradise by God! Come, ye faithful, let us bow down before that by which we have been vouchsafed to crush the heads of the invisible foe! Come, all ye peoples of our fatherland, let us honour the Cross of the Lord with hymns, crying Rejoice, O Cross, thou perfect deliverance of fallen Adam; for in thee do most faithful rulers boast, for through thy power are the Moslem hordes mightily subdued! And now, venerating with fear thee upon whom God was nailed, we Christians render glory, saying O Lord Who wast nailed thereto, have mercy upon us, in that Thou art good and lovest mankind!
— Hymn from Orthros, Elevation of the Holy Cross
We truly have but one enemy; that is, the enemy of our salvation, the Devil. And, in spiritual warfare, there is no greater weapon than the sign of the Life Giving Cross of Christ. It is the Cross that subdues the enemy! It is the Cross that delivers fallen mankind! It is the Cross that is victorious!
O Lord, save Thy people, and bless Thine inheritance. Grant victory to Orthodox Christians over their adversaries. And by Thy Cross, preserve Thy habitation.
— Troparion of the Cross
