Origen of Alexandria

If therefore we wish to receive the bread of blessing from Jesus, who is eager to give it, we should enter the city and go into the house, prepared beforehand, where Jesus kept the Passover with his disciples. We ascend to the “large, furnished upper room” where he “took the cup” from the Father and, “when he had given thanks, he gave it to them” who had gone up there with him and said, “Drink this, for this is my blood of the new covenant.” The cup was both consumed and poured out. It was consumed by the disciples. It was “poured out for the remission of sins” committed by those who drink it. If you want to know in what sense it was poured out, compare this saying with what was written [by Paul]: “God’s love has been poured into our hearts.” If the blood of the covenant was poured into our hearts for the remission of our sins, then by the pouring of that potable blood into our hearts all the sins we have committed in the past will be remitted and wiped clean. He who took the cup and said “drink this all of you” will not depart from us who drink it but will drink it with us (since he himself is in each of us), for we are unable alone or without him either to eat of the bread or to drink of the fruit of the true vine. You should not marvel that he who is himself the bread also eats the bread with us or that he who is himself the cup of the fruit of the vine also drinks it with us. This is possible because the Word of God is omnipotent and is at once the bearer of many different names, for the multitude of his virtues are innumerable, since he is himself every virtue.

They didn’t fall away in the daytime but at night, and it was on the night in which Jesus was betrayed. Peter also denied Christ at night, not during the day. Moreover, it was still in the middle of the night, since the cock had not yet crowed. Anyone who questions how the disciples could have fallen away after seeing such great signs and wonders and after hearing words of equal power (for the signs and wonders were performed by his words) should realize that Christ wanted to demonstrate through this warning that just as “no one can say that Jesus is Lord except by the Holy Spirit,” so also no one is able to keep from falling away except by the Holy Spirit. When what Jesus had foretold came to pass, “You will all fall away from me this night,” it was still true that “the Holy Spirit had not yet been given because Jesus had not yet been glorified.” If we … who have already professed Jesus to be Lord by the Holy Spirit (for “all who are led by the Spirit of God are sons of God”), then fall away or deny him, we will not have an excuse like those who fell away or denied him without the Holy Spirit.

But you will ask, whether it were possible that Peter should not have been offended, when once the Saviour had said, All ye shall be offended in me. To which one will answer, what is foretold by Jesus must of necessity come to pass; and another will say, that He who at the prayer of Ninevites turned away the wrath He had denounced by Jonas, might also have averted Peter's offence at his entreaty. But his presumptuous confidence, prompted by zeal indeed but not a cautious zeal, became the cause not only of offence but of a thrice repeated denial. And since He confirmed it with the sanction of an oath, some one will say that it was not possible that he should not have denied Him. For Christ would have spoken falsely when he said, Verily I say unto thee, if Peter's assertion, I will not deny thee, had been true. It seems to me that the other disciples having in view not that which was first said, All ye shall be offended, but that which was said to Peter, Verily I say unto thee, &c. made a like promise with Peter because they were not comprehended in the prophecy of denial. Peter said unto him, Though I should die with thee, yet will I not deny thee. Likewise also said all the disciples. Here again Peter knows not what he says; he could not die with Him who was to die for all mankind, who were all in sin, and had need of some one to die for them, not that they should die for others.

He took with Him the self-confident Peter, and the others, that they might see Him falling on His face and praying, and might learn not to think great things, but little things of themselves, and not to be hasty in promising, but careful in prayer. And therefore, He went forward a little, not to go far from them, but that He might be near them in His prayer. Also, He who had said above, Learn of me, for I am meek and lowly in heart, now commendably humbling Himself, falls on His face. But He shows His devotion in His prayer, and as beloved and well-pleasing to His Father, He adds, Not as I will, but as thou wilt, teaching us that we should pray, not that our own will, but that God's will, should be done. And as He began to have fear and sorrow, He prays accordingly that the cup of His Passion may pass from Him, yet not as He wills, but as His Father wills; wills, that is, not according to His Divine and impassible Substance, but according to His human and weak nature. For in taking upon Him the nature of human flesh, He fulfilled all the properties thereof, that it might be seen that He had flesh not in appearance only, but in-reality. The believer indeed must in the first instance be loth to incur pain, seeing it leads to death, and he is a man of flesh; but if it be God's will, he acquiesces because he is a believer. For as we ought not to be too confident that we may not seem to make a boast of our own strength; so neither ought we to be distrustful, lest we should seem to charge God our helper with weakness. It is to be observed that Mark and Luke write the same, but John does not introduce this prayer of Jesus', that this cup may pass from Him, because the first three are rather occupied about Him, according to His human nature, John according to His divine. Otherwise; Jesus makes this petition, because He sees what the Jews will suffer for requiring His death.

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.

As long as Jesus was present, his disciples did not sleep. After he had walked away a short distance, they were unable to watch for even one hour in his absence. For this reason we should pray that Jesus will not leave us for even a short while but will fulfill what he promised when he said to us, "And I am with you all days, even to the end of the world." In this way will we keep watch as he banishes sleep from our souls, to make it possible for us to fulfill his command: "Do not give sleep to your eyes or slumber to your eyelids, that you may escape as a doe from the nets and a bird from the snare of the fowlers." But coming to the disciples and finding them asleep, he arouses them with a word and tells them to listen, so he may as it were say to those who are listening: "How is it that you were not able to watch with me for even one hour?"He orders us then to be wakeful so we may keep watch and pray. Now that person watches who does good works, that person watches who diligently attends to the truth of the faith lest he be ensnared by any shady teaching. He who watches and prays in this way will have his prayer heard. This is what the Lord means when he says, "Watch and pray." We should first watch and, while watching, we should pray.
