1 When the grand and lengthened discourse was concluded which the Lord delivered after supper, and on the eve of shedding His blood for us, to the disciples who were then with Him, and had added the prayer addressed to His Father, the evangelist John began thereafter the narrative of His passion in these words: “When Jesus had so spoken, He went forth with His disciples over the brook Cedron, where was a garden, into the which He entered, and His disciples. And Judas also, who betrayed Him, knew the place; for Jesus oft-times resorted there with His disciples.” What he here relates of the Lord entering the garden with His disciples did not take place immediately after He had brought the prayer to a close, of which he says, “When Jesus had spoken these words:” but certain other incidents were interposed, which are passed over by the present evangelist and found in the others; just as in this one are found many things on which the others are similarly silent in their own narratives. But any one who desires to know how they all agree together, and the truth which is advanced by one is never contradicted by another, may seek for what he wants, not in these present discourses, but in other elaborate treatises; but he will master the subject not by standing and listening, but rather by sitting down and reading, or by giving his closest attention and thought to one who does so. Yet let him believe before he know, whether he be able also to come to such a knowledge in this life, or find it impossible through some existing entanglements, that there is nothing written by any one evangelist, as far as regards those who have been received by the Church into canonical authority, that can be contrary to his own or another's equally veracious narrative. At present, therefore, let us look at the narrative of the blessed John, which we have undertaken to expound, without any comparison with the others, and without lingering over anything in it that is already sufficiently clear; so that where it is needful to do so, we may the better answer the demand. Let us, therefore, not take His words, “When Jesus had spoken these words, He went forth with His disciples over the brook Cedron, where was a garden, into the which He entered, and His disciples,” as if it were immediately after the utterance of these words that He entered the garden; but let the clause, “When Jesus had spoken these words,” bear this meaning, that we are not to suppose Him entering the garden before He had brought these words to a close.
2. “Judas also,” he says, “who betrayed Him, knew the place; for Jesus oft-times resorted there with His disciples.” There, accordingly, the wolf, clad in a sheep's skin, and tolerated among the sheep by the profound counsel of the Father of the family, learned where he might opportunely scatter the slender flock, and lay his coveted snares for the Shepherd. “Judas then,” he adds, “having received a cohort, and officers from the chief men and the Pharisees, comes there with lanterns, and torches, and weapons.” It was a cohort, not of Jews, but of soldiers. We are therefore to understand it as having been received from the governor, as if for the purpose of securing the person of a criminal, and by preserving the forms of legal power, to deter any from venturing to resist his captors: although at the same time so great a band had been assembled, and came armed in such a way as either to terrify or even attack any one who should dare to make a stand in Christ's defense. For only in so far was His power concealed and prominence given to His weakness, that these very measures were deemed necessary by His enemies to be taken against Him, for whose hurt nothing would have sufficed but what was pleasing to Himself; in His own goodness making a good use of the wicked, and doing what was good in regard to the wicked, that He might transform the evil into the good, and distinguish between the good and the evil.
3. “Jesus, therefore,” as the evangelist proceeds to say, “knowing all things that should come upon Him, went forth and says unto them, Whom do you seek? They answered Him, Jesus of Nazareth. Jesus says unto them, I am [He]. And Judas also, who betrayed Him, stood with them. As soon then as He had said unto them, I am He, they went backward, and fell to the ground.” Where now were the military cohort, and the servants of the chief men and the Pharisees? Where the terror and protection of weapons? His own single voice uttering the words, “I am [He],” without any weapon, smote, repelled, prostrated that great crowd, with all the ferocity of their hatred and terror of their arms. For God lay hid in that human flesh; and eternal day was so obscured in those human limbs, that with lanterns and torches He was sought for to be slain by the darkness. “I am [He],” He says; and He casts the wicked to the ground. What will He do when He comes as judge, who did this when giving Himself up to be judged? What will be His power when He comes to reign, who had this power when He came to die? And now everywhere through the gospel Christ is still saying, “I am [He];” and the Jews are looking for antichrist, that they may go backward and fall to the ground, as those who have abandoned what is heavenly, and are hankering after the earthly. It was for the very purpose of apprehending Jesus that His persecutors accompanied the traitor: they found the One they were seeking, for they heard, “I am [He].” Why, then, did they not seize Him, but went backward and fell, but just because so He pleased, who could do whatever He pleased? But had He never permitted them to apprehend Him, they would certainly not have done what they came to do, but no more would He be doing what He came to do. They, verily, in their mad rage, sought for Him to put Him to death; but He, too, in giving Himself to death, was seeking for us. Accordingly, having thus shown His power to those who had the will, but not the power, to hold Him; let them now hold Him that He may work His own will with those who know it not.
4. “Then asked He them again, Whom do you seek? And they said, Jesus of Nazareth. Jesus answered, I have told you that I am [He]. If therefore ye seek me, let these go their way: that the saying might be fulfilled which He spoke, That of those whom You have given me I have lost none.” “If you seek me,” He says, “let these go their way.” He sees His enemies, and they do what He bids them: they let those go their way, whom He would not have perish. But were they not afterwards to die? How then, if they died now, should He lose them, were it not that as yet they did not believe in Him, as all believe who perish not?
