Origen

There were, I conclude, two ways in which this cup of Passion might pass from the Lord. If He should drink it, it would pass away from Him, and afterwards from the whole race of mankind also; if He should not drink it, it would perhaps pass from Him, but from men it would not pass. He would fain therefore that it should so pass from Him as that He should not at all taste its bitterness, yet only if it were possible, saving the righteousness of God. If it were not possible, He was rather willing to drink it, that so it might pass from Him, and from the whole race of mankind rather than against His Father’s will shun the drinking thereof.
