Augustine of Hippo

And where he could do anything, there in every respect he was conquered; and wherein he received outwardly the power of slaying the Lord in the flesh, therein his inward power, by which he held ourselves, was slain. For it was brought to pass that the bonds of many sins in many deaths were loosed, through the one death of One which no sin had preceded. Which death, though not due, the Lord therefore rendered for us, that the death which was due might work us no hurt. For He was not stripped of the flesh by obligation of any authority, but He stripped Himself. For doubtless He who was able not to die, if He would not, did die because He would: and so He made a show of principalities and powers, openly triumphing over them in Himself. For whereas by His death the one and most real sacrifice was offered up for us, whatever fault there was, whence principalities and powers held us fast as of right to pay its penalty, He cleansed, abolished, extinguished; and by His own resurrection He also called us whom He predestinated to a new life; and whom He called, them He justified; and whom He justified, them He glorified.
