For He took upon Him the flesh in which we have sinned that by wearing our flesh He might forgive sins; a flesh which He shares with us by wearing it, not by sinning in it. He blotted out through death the sentence of death, that by a new creation of our race in Himself He might sweep away the penalty appointed by the former Law. He let them nail Him to the cross that He might nail to the curse of the cross and abolish all the curses to which the world is condemned. He suffered as man to the utmost that He might put powers to shame. For Scripture had foretold that He Who is God should die; that the victory and triumph of them that trust in Him lay in the fact that He, Who is immortal and cannot be overcome by death, was to die that mortals might gain eternity.
– Hilary of Poitiers, “On the Trinity”, Book 1.13
But how was the Son to be glorified? He had been born of a virgin, from cradle and childhood He had grown to man’s estate, through sleep and hunger and thirst and weariness and tears He had lived man’s life: even now He was to be spitted on, scourged, crucified And why? These things were ordained for our assurance that in Christ is pure man. But the shame of the cross is not ours; we are not sentenced to the scourge, nor defiled by spitting. The Father glorifies the Son; how? He is next nailed to the cross.
Hilary of Poitiers, “On the Trinity”, Book 3.10
Every action, therefore, and performance of miracles by Christ are most great and divine and marvellous: but the most marvellous of all is His precious Cross. For no other thing has subdued death, expiated the sin of the first parent, despoiled Hades, bestowed the resurrection, granted the power to us of contemning the present and even death itself, prepared the return to our former blessedness, opened the gates of Paradise5, given our nature a seat at the right hand of God, and made us the children and heirs of God, save the Cross of our Lord Jesus Christ. For by the Cross7 all things have been made right. So many of us, the apostle says, as were baptized into Christ, were baptized into His death, and as many of you as have been baptized into Christ, have put on Christ9. Further, Christ is the power of God and the wisdom of God. Lo! the death of Christ, that is, the Cross, clothed us with the enhypostatic wisdom and power of God. And the power of God is the Word of the Cross, either because God’s might, that is, the victory over death, has been revealed to us by it, or because, just as the four extremities of the Cross are held fast and bound together by the bolt in the middle, so also by God’s power the height and the depth, the length and the breadth, that is, every creature visible and invisible, is maintained…
The tree of life which was planted by God in Paradise pre-figured this precious Cross. For since death was by a tree, it was fitting that life and resurrection should be bestowed by a tree.
John of Damascus, “An Exact Exposition of the Orthodox Faith”, Chapter XI, Concerning the Cross
“Many indeed are the wondrous happenings of that time: God hanging from a cross, the sun made dark and again flaming out; for it was fitting that creation should mourn with its creator. The temple veil rent, blood and water flowing from his side: the one as from a man, the other as from what was above man; the earth shaken, the rocks shattered because of the rock; the dead risen to bear witness to the final and universal resurrection of the dead. The happenings at the sepulcher and after the sepulcher, who can fittingly recount them? Yet no one of them can be compared to the miracle of my salvation. A few drops of blood renew the whole world, and do for all men what the rennet does for the milk: joining us and binding us together.”
Gregory Nazianzen – On the Holy Passion, Oration 45.1
And moreover, in His very passion and cross, before they had reached the cruelty of death and the effusion of blood, what infamies of reproach were patiently heard, what mockings of contumely were suffered, so that He received the spittings of insulters, who with His spittle had a little before made eyes for a blind man; and He in whose name the devil and his angels is now scourged by His servants, Himself suffered scourgings! He was crowned with thorns, who crowns martyrs with eternal flowers. He was smitten on the face with palms, who gives the true palms to those who overcome. He was despoiled of His earthly garment, who clothes others in the vesture of immortality. He was fed with gall, who gave heavenly food. He was given to drink of vinegar, who appointed the cup of salvation. That guiltless, that just One,—nay, He who is innocency itself and justice itself,—is counted among transgressors, and truth is oppressed with false witnesses. He who shall judge is judged; and the Word of God is led silently to the slaughter. And when at the cross, of the Lord the stars are confounded, the elements are disturbed, the earth quakes, night shuts out the day, the sun, that he may not be compelled to look on the crime of the Jews, withdraws both his rays and his eyes, He speaks not, nor is moved, nor declares His majesty even in His very passion itself. Even to the end, all things are borne perseveringly and constantly, in order that in Christ a full and perfect patience may be consummated.
Cyprian of Carthage, “On the Advantage of Patience”
