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.
Then again considering the benefit that would accrue to the whole world from His Passion, He says, But not as I will, but as thou wilt; i. e. If it be possible for all these benefits which shall result from My Passion to be procured without it, let it pass from Me, and both the world be saved, and the Jews not be condemned in putting Me to death. But if the salvation of many cannot be procured without the destruction of a few, saving Thy justice, let it not pass away. Scripture, in many places, speaks of passion as a cup that is drained; and it is drained by him, who in testimony suffers whatever is inflicted upon him. He sheds it, on the contrary, who denies in order to avoid suffering.
