25. These things I have spoken to you. He adds this, that they may not despair, though they may have profited less than they ought to have done; for at that time he scattered a seed of doctrine, which lay hidden, and, as it were, suffocated in the disciples. He therefore exhorts them to entertain good hopes, until fruit be yielded by the doctrine which might now appear to be useless. In short, he testifies that in the doctrine which they had heard they have abundant ground of consolation, and that they ought not to seek it anywhere else. And if they do not immediately see it, he bids them be of good courage, until the Holy Spirit, who is the inward Teacher, speak the same thing in their hearts. This admonition is highly useful to all; for, if we do not immediately understand what Christ teaches, we begin to grow weary, and grudge to bestow unprofitable labor on what is obscure. But we must bring an eager desire to receive instruction; we must lend our ears and give attention, if we desire to make due proficiency in the school of God; and especially we need patience, until the Holy Spirit enable us to understand what we thought that we had often read or heard to no purpose. That the desire of learning may not be weakened in us, or that we may not fall into despair, when we do not immediately perceive the meaning of Christ speaking to us, let us know that this is spoken to us all.

The Holy Spirit will bring to your remembrance all things that I have said to you. It is indeed a punishment threatened by Isaiah against unbelievers, that the Word of God shall be to them as a book that is sealed, (Isaiah 29:11) but in this manner, also, the Lord frequently humbles his people. We ought, therefore, to wait patiently and mildly for the time of revelation, and must not, on that account, reject the word. When Christ testifies that it is the peculiar office of the Holy Spirit to teach the apostles what they had already learned from his mouth, it follows that the outward preaching will be vain and useless, if it be not accompanied by the teaching of the Spirit. God has therefore two ways of teaching; for, first, he sounds in our ears by the mouth of men; and, secondly, he addresses us inwardly by his Spirit; and he does this either at the same moment, or at different times, as he thinks fit.

But observe what are all these things which he promises that the Spirit will teach. He will suggest, he says, or bring to your remembrance, all that I have said. Hence it follows, that he will not be a builder of new revelations. By this single word we may refute all the inventions which Satan has brought into the Church from the beginning, under the pretense of the Spirit. Mahomet and the Pope agree in holding this as a principle of their religion, that Scripture does not contain a perfection of doctrine, but that something loftier has been revealed by the Spirit. From the same point the Anabaptists and Libertines, in our own time, have drawn their absurd notions. But the spirit that introduces any doctrine or invention apart from the Gospel is a deceiving spirit, and not the Spirit of Christ. What is meant by the Spirit being sent by the Father in the name of Christ, I have already explained.

27. Peace I leave with you. By the word peace he means prosperity, which men are wont to wish for each other when they meet or part; for such is the import of the word peace in the Hebrew language. He therefore alludes to the ordinary custom of his nation; as if he had said, I give you my Farewell. But he immediately adds, that this peace is of far greater value than that which is usually to be found among men, who generally have the word peace but coldly in their mouth, by way of ceremony, or, if they sincerely wish peace for any one, yet cannot actually bestow it. But Christ reminds them that his peace does not consist in an empty and unavailing wish, but is accompanied by the effect. In short, he says that he goes away from them in body, but that his peace remains with the disciples; that is, that they will be always happy through his blessing.

Let not your heart be troubled. He again corrects the alarm which the disciples had felt on account of his departure. It is no ground for alarm, he tells them; for they want only his bodily presence, but will enjoy his actual presence through the Spirit. Let us learn to be always satisfied with this kind of presence, and let us not give a loose reign to the flesh, which always binds God by its outward inventions.

28. If you loved me you would rejoice. The disciples unquestionably loved Christ, but not as they ought to have done; for some carnal affection was mixed with their love, so that they could not endure to be separated from him; but if they had loved him spiritually, there was nothing which they would have had more deeply at heart, than his return to the Father.

For the Father is greater than I. This passage has been tortured in various ways. The Aryans, in order to prove that Christ is some sort of inferior God, argued that he is less than the Father. The orthodox Fathers, to remove all ground for such a calumny, said that this must have referred to his human nature; but as the Aryans wickedly abused this testimony, so the reply given by the Fathers to their objection was neither correct nor appropriate; for Christ does not now speak either of his human nature, or of his eternal Divinity, but, accommodating himself to our weakness, places himself between God and us; and, indeed, as it has not been granted to us to reach the height of God, Christ descended to us, that he might raise us to it. You ought to have rejoiced, he says, because I return to the Father; for this is the ultimate object at which you ought to aim. By these words he does not show in what respect he differs in himself from the Father, but why he descended to us; and that was that he might unite us to God; for until we have reached that point, we are, as it were, in the middle of the course. We too imagine to ourselves but a half-Christ, and a mutilated Christ, if he do not lead us to God.

There is a similar passage in the writings of Paul, where he says that Christ

will deliver up the Kingdom to God his Father, that God may be all in all,
(1 Corinthians 15:24.)

Christ certainly reigns, not only in human nature, but as he is God manifested in the flesh. In what manner, therefore, will he lay aside the kingdom? It is, because the Divinity which is now beheld in Christ's face alone, will then be openly visible in him. The only point of difference is, that Paul there describes the highest perfection of the Divine brightness, the rays of which began to shine from the time when Christ ascended to heaven. To make the matter more clear, we must use still greater plainness of speech. Christ does not here make a comparison between the Divinity of the Father and his own, nor between his own human nature and the Divine essence of the Father, but rather between his present state and the heavenly glory, to which he would soon afterwards be received; as if he had said, "You wish to detain me in the world, but it is better that I should ascend to heaven." Let us therefore learn to behold Christ humbled in the flesh, so that he may conduct us to the fountain of a blessed immortality; for he was not appointed to be our guide, merely to raise us to the sphere of the moon or of the sun, but to make us one with God the Father.
