Origen
Catena Aurea · Matthäusevangelium 26
And he went a little farther, and fell on his face, and prayed, saying, O my Father, if it be possible, let this cup pass from me: nevertheless not as I will, but as thou wilt. And he cometh unto the disciples, and findeth them asleep, and saith unto Peter, What, could ye not watch with me one hour? Watch and pray, that ye enter not into temptation: the spirit indeed is willing, but the flesh is weak. He went away again the second time, and prayed, saying, O my Father, if this cup may not pass away from me, except I drink it, thy will be done. And he came and found them asleep again: for their eyes were heavy. And he left them, and went away again, and prayed the third time, saying the same words.
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.
