18. I speak not of you all. He again declares that there is one among the disciples who, in reality, is the very reverse of a disciple; and he does so, partly for the sake of Judas, in order to render him the more inexcusable, and partly for the sake of the others, 'That they may not be overpowered by the ruin of Judas. Not only does he encourage them still to persevere in their calling when Judas falls away; but as the happiness which he speaks of is not common to all, he exhorts them to desire it with so much the greater eagerness, and to adhere to it the more firmly.

I know whom I have chosen. This very circumstance -- that they will persevere -- he ascribes to their election; for the virtue of men, being frail, would tremble at every breeze, and would be laid down by the feeblest stroke, if the Lord did not uphold it by his hand. But as he governs those whom he has elected, all the engines which Satan can employ will not prevent them from persevering to the end with unshaken firmness. And not only does he ascribe to election their perseverance, but likewise the commencement of their piety. Whence does it arise that one man, rather than another, devotes himself to the word of God? It is, because he was elected. Again, whence does it arise that this man makes progress, and continues to lead a good and holy life, but because the purpose of God is unchangeable, to complete the work which was begun by his hand? In short, this is the source of the distinction between the children of God and unbelievers, that the former are drown to salvation by the Spirit of adoption, while the latter are hurried to destruction by their flesh, which is under no restraint. Otherwise Christ might have said, "know what kind of person each of you will be;" but that they may not claim anything for themselves, but, on the contrary, may acknowledge that, by the grace of God alone, and not by their own virtue, they differ from Judas, he places before them that election by free grace on which they are founded. Let us, therefore, learn that every part of our salvation depends on election.

In another passage he includes Judas in the number of the elect.

Have not I chosen (or, elected) you twelve,
and one of you is a devil? (John 6:70.)²

But in that passage the mode of expression, though different, is not opposite', for there the word denotes a temporal election, by which God appoints us to any particular work; in the same manner as Saul, who was elected to be a king, and yet was a reprobate. But here Christ speaks of the eternal election, by which we become the children of God, and by which God predestinated us to life before the creation of the world. And, indeed, the reprobate are sometime, endued by God with the gifts of the Spirit, to execute the office with which he invests them. Thus, in Saul, we perceive, for a time, the splendor of royal virtues, and thus Judas also was distinguished by eminent gifts, and such as were adapted to an apostle of Christ. But this is widely different from the sanctification of the Holy Spirit, which the Lord bestows on none but his own children; for he renews them in understanding and heart, that they may be holy and unblameable in his sight. Besides, that sanctification has a deep root in them, which cannot be removed; because the adoption of God is without repentance. Meanwhile, let us regard it as a settled point, that it results from the election of God, when, having embraced by faith the doctrine of Christ, we also follow it during our life; and that this is the only cause of our happiness, by which we are distinguished from the reprobate; for they, being destitute of the grace of the Spirit, miserably perish, while we have Christ for our guardian, who guides us by his hand, and upholds us by his power.

Besides, Christ gives here a clear proof of his Divinity; first, when he declares that he does not judge after the manner of men; and, secondly, when he pronounces himself to be the Author of election. For when he says, I know, the knowledge, of which he speaks, belongs peculiarly to God; but the second proof -- contained in the words, whom I have chosen -- is far more powerful, for he testifies that they who were elected before the creation of the world were elected by himself. So remarkable a demonstration of his Divine power ought to affect us more deeply, than if the Scripture had called him God a hundred times.

That the Scripture may be fulfilled. It might have been thought improper that one should have been elected to so honorable a rank, who yet did not possess true piety; for it might readily have been objected, Why did not Christ elect one whom he intended to admit into the number of the Apostles? or rather Why did he appoint a man to be an Apostle, who, he well knew, would become so wicked? He explains that this must have happened, because it was foretold; of at least, that it was no new occurrence, for David had experienced the same thing. For some think that it is a prediction quoted, which properly applies to Christ; while others think that it is merely a comparison, that, as David was basely betrayed by a private enemy, so a similar condition awaits the children of God. According to the latter, the meaning would be: That one of my disciples wickedly betrays his Master, is not the first instance of treachery that has taken place in the world; but, on the contrary, we now experience what Scripture declares to have happened in ancient times." But, as in David there was shadowed out what was afterwards to be seen more fully in Christ, I readily agree with the former expositors, who think that this was strictly the fulfillment of that which David, by the Spirit of prophecy, had foretold, (Psalm 41:9.) Besides, some are of opinion that the clause under consideration does not contain a complete sense, and needs to have the principal verb supplied. But if we read it continuously, That the Scripture may be fulfilled, he who eateth bread with me lifteth up his heel against me, there will be nothing wanting.

To lift up the heel is a metaphorical expression, and means, to attack a person in an unperceived manner, under the pretense of friendship, so as to gain an advantage over him, when he is not on his guard. Now what Christ suffered, who is our Head and our Pattern, we, who are his members, ought to endure patiently. And, indeed, it has usually happened in the Church in almost every age, that it has had no enemies more inveterate than the members of the Church; and, therefore, that believers may not have their minds disturbed by such atrocious wickedness, let them accustom themselves early to endure the attacks of traitors.

19. I tell you this now, before it happen. By this statement he reminds his disciples that, when one of their number becomes a reprobate, this is so far from being a good reason for their being discouraged, that it ought to be a more full confirmation of their faith. For if we did not see before our eyes, in the Church, what has been foretold about her distresses and struggles, a doubt might justly arise in our minds, Where are the prophecies? But when the truth of Scripture agrees with our daily experience,17 then do we perceive more clearly, that God takes care of us, and that we are governed by his providence.

That you may believe that I am. ³ By the phrase, that I am, he means that he is that Messiah who had been promised; not that the conduct of Judas, as a traitor, was the first event that led the disciples to the exercise of faith, but because their faith made greater progress, when they arrived at the experience of those things which they had formerly heard from the mouth of Christ. Now this may be explained in two ways; either that Christ says that they will believe after the event has happened, because there was nothing which was hidden from him, or that nothing will be wanting in him of all that the Scripture testifies concerning Christ. As the two interpretations agree well enough together, I leave my readers at liberty to choose which of them they will prefer.

20. Verily, verily, I tell you. In these words either the Evangelist relates a discourse on a different subject, and in a broken and imperfect state, or, Christ intended to meet the offense which was likely to arise from the crime of Judas; for the Evangelists do not always exhibit the discourses of Christ in unbroken succession, but sometimes throw together, in heaps, a variety of statements. It is more probable, however, that Christ intended to provide against this scandal. There is too good evidence that we are very ready to be wounded by bad examples; for, in consequence of this, the revolt of one man inflicts a deadly wound on two hundred others, while the steadiness of ten or twenty pious men hardly edifies a single individual. On this account, while Christ was placing such a monster before the eyes of his disciples, it was also necessary that he should stretch out his hand to them, lest, struck by the novelty, they should fall back. Nor was it only on their account that he said this, but he also consulted the advantage of those who should come after; for, otherwise, the remembrance of Judas might, even at the present day:, do us grievous injury. When the devil cannot estrange us from Christ by hatred of his doctrine, he excites either dislike or contempt of the ministers themselves.

Now this admonition of Christ shows that it is unreasonable that the impiety of any whose conduct is wicked or unbecoming their office, should at all diminish the apostolical authority. The reason is, we ought to contemplate God, the Author of the ministry, in whom, certainly, we find nothing which we have a right to despise; and next, we ought to contemplate Christ, who, having been appointed by the Father to be the only Teacher, speaks by his apostles. Whoever, then, does not deign to receive the ministers of the Gospel, rejects Christ in them, and rejects God in Christ.

The Papists act a foolish and ridiculous part, when they endeavor to obtain this applause for themselves, in order exhibit their tyranny. For, in the first place, they adorn themselves with begged and borrowed feathers, having no resemblance to the apostles of Christ; and, secondly, granting that they are apostles, nothing was farther from Christ's intention, in this passage, than to transfer his own right to men; for what else is it to receive those whom Christ sends, but to give place to them, that they may fulfill the office which has been committed to them?
