Hilary of Poitiers
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.
Otherwise; He says not, Let this cup pass away from Me, for that would be the speech of one who feared it; but He prays that it may pass not so as that He should be passed over, but that when it has passed from Him, it may go to another. His whole fear then is for those who were to suffer, and therefore He prays for those who were to suffer after Him, saying, Let this cup pass from me, i. e. as it is drunk by Me, so let it be drunk by these, without mistrust, without sense of pain, without fear of death. He says, If it be possible, because flesh and blood shrink from these things, and it is hard for human bodies not to sink beneath their infliction. That He says, Not as I will, but as thou wilt, He would fain indeed that they should not suffer, lest their faith should fail in their sufferings, if indeed we might attain to the glory of our joint inheritance with Him without the hardship of sharing in His Passion. He says, Not as I will, but as thou wilt,because it is the Father’s will that strength to drink of the cup should pass from Him to them, that the Devil might be vanquished not so much by Christ as by His disciples also.
