1. In the beginning was the Speech. In this introduction he asserts the eternal Divinity of Christ, in order to inform us that he is the eternal God, who was manifested in the flesh, The design is, to show it to have been necessary that the restoration of mankind should be accomplished by the Son…

2. He was in the beginning. In order to impress more deeply on our minds what had been already said, the Evangelist condenses the two preceding clauses into a brief summary, that the Speech always was, and that he was with God; so that it may be understood that the beginning was before all time.

3. All things were made by him. Having affirmed that the Speech is God, and having asserted his eternal essence, he now proves his Divinity from his works.

4. In him was life. Hitherto he has taught us, that by the Speech of God all things were created. He now attributes to him, in the same manner, the preservation of those things which had been created, as if he had said, that in the creation of the world there was not merely displayed a sudden…

5. And the light shineth in darkness. It might be objected, that the passages of Scripture in which men are called blind are so numerous and that the blindness for which they are condemned is but too well known. For in all their reasoning faculties they miserably fail.

6. There was a man. The Evangelist now begins to discourse about the manner in which the Son of God was manifested in flesh; and that none may doubt that Christ is the eternal Son of God, he relates that Christ was announced by John the Baptist, as his herald.

7. He came for a testimony. The end of his calling is briefly noticed; which was, that he might prepare a Church for Christ, as, by inviting all to Christ, he shows plainly enough that he did not come on his own account.

8. He was not that light. So far was John from needing commendation, that the Evangelist gives this warning, lest his excessive brightness might obscure the glory of Christ.

9. The true light was. The Evangelist did not intend to contrast the true light with the false, but to distinguish Christ from all others, that none might imagine that what is called light belongs to him in common with angels or men.

10. He was in the world. He accuses men of ingratitude, because of their own accord, as it were, they were so blinded, that the cause of the light which they enjoyed was unknown to them.

11. He came into his own. Here is displayed the absolutely desperate wickedness and malice of men; here is displayed their execrable impiety, that when the Son of God was manifested in flesh to the Jews, whom God had separated to himself from the other nations to be His own heritage, he was not…

12. But to as many as received him. That none may be retarded by this stumbling-block, that the Jews despised and rejected Christ, the Evangelist exalts above heaven the godly who believe in him; for he says that by faith they obtain this glory of being reckoned the sons of God.

14. And the Speech was made flesh. The Evangelist shows what was that coming of Christ which he had mentioned; namely, that having been clothed with our flesh, he showed himself openly to the world.

15. John testifieth. He now relates what was the preaching of John. By using the verb testifieth (μαρτυρεῖ) in the present tense, he denotes a continued act, and certainly this doctrine must be continually in force, as if the voice of John were continually resounding in the ears of men.

16. And out of his fullness. He begins now to preach about the office of Christ, that it contains within itself an abundance of all blessings, so that no part of salvation must be sought anywhere else.

17. For the Law was given by Moses. This is an anticipation, by which he meets an objection that was likely to arise; for so highly was Moses esteemed by the Jews that they could hardly receive anything that differed from him.

18. No man hath ever seen God. Most appropriately is this added to confirm the preceding statement; for the knowledge of God is the door by which we enter into the enjoyment of all blessings; and as it is by Christ alone that God makes himself known to us, hence too it follows that we ought to seek…

19. And this is the testimony. Hitherto the Evangelist has related the preaching of John about Christ; he now comes down to a more illustrious testimony, which was delivered to the ambassadors of the Priests, that they might convey it to Jerusalem.

20. And he confessed, and denied not. That is, he confessed openly, and without any ambiguity or hypocrisy. The word confess, in the first instance, means generally, that he stated the fact as it really was. In the second instance, it is repeated in order to express the form of the confession.

21. Art thou Elijah? Why do they name Elijah rather than Moses? It was because they learned from the prediction of Mal. 4:2, Mal. 4:5, that when the Messiah, the Sun of Righteousness, should arise, Elijah would be the morning star to announce his approach.

23. The voice of him who crieth. As he would have been chargeable with rashness in undertaking the office of teaching, if he had not received a commission, he shows what was the duty which he had to perform, and proves it by a quotation from the Prophet Isa. 60:3.

24. Were of the Pharisees. He says that they were Pharisees, who at that time held the highest rank in the Church; and he says so in order to inform us, that they were not some contemptible persons of the order of the Levites, but men clothed with authority.

25. Why then dost thou baptize? By laying down those three degrees, they appear to form a very conclusive argument: if thou art not the Christ, nor Elijah, nor a prophet; for it does not belong to every man to institute the practice of baptism. The Messiah was to be one who possessed all authority.

26. I baptize with water. This ought to have been abundantly sufficient for the correction of their mistake, but a reproof otherwise clear is of no advantage to the deaf; for, when he sends them to Christ, and declares that Christ is present, this is a clear proof not only that he was divinely…

27. Who coming after me. Here he says two things; first, that Christ was behind him in the order of time; but, secondly, that he was far before him in rank and dignity, because the rather preferred him to all.

28. These things were done in Bethabara. The place is mentioned, not only to authenticate the narrative, but also to inform us that this answer was given amidst a numerous assembly of people; for there were many who flocked to John’s baptism, and this was his ordinary place for baptizing.

29. The next day. There can be no doubt that John had already spoken about the manifestation of the Messiah; but when Christ began to appear, he wished that his announcement of him should quickly become known, and the time was now at hand when Christ would put an end to John’s ministry, as, when…

30. This is he of whom I said. He comprehends every thing in a few words, when he declares that Christ is the person who, he said, was to be preferred to him; for hence it follows that John is nothing more than a herald sent on his account; and hence again it is evident that Christ is the Messiah.

31. And I knew him not. That his testimony may not be suspected of having been given either from friendship or favor, he anticipates such a doubt, by affirming that he had no other knowledge of Christ than what he had obtained by divine inspiration.

32. I saw the Spirit, descending like a dove. This is not a literal but a figurative mode of expression; for with what eyes could he see the Spirit? But as the dove was a certain and infallible sign of the presence of the Spirit, it is called the Spirit, by a figure of speech in which one name is…

33. Upon whom thou shalt see the Spirit descending. Here a difficult question arises; for if John did not know Christ, why does he refuse to admit him to baptism? To a person whom he did not know he would not say, I ought rather to be baptized by thee, Some reply, that he knew him to such an extent…

34. I saw and testified. He means that what he declares is not doubtful; because God was pleased to make him fully and thoroughly acquainted with those things of which he was to be the witness to the world; and it is worthy of notice, that he testified that Christ was the Son of God, because he who…

36. Behold the Lamb of God! Hence appears more clearly what I have already stated, that when John perceived that he was approaching the end of his course, he labored incessantly to resign his office to Christ. His firmness too gives greater credit to his testimony.

38. Rabbi. This name was commonly given to persons of high rank, or who possessed any kind of honor. But the Evangelist here points out another use of it which was made in his own age, which was, that they addressed by this name the teachers and expounders of the word of God.

39. It was about the tenth hour; that is, the evening was approaching, for it was not more than two hours till sunset. The day was at that time divided by them into twelve hours, which were longer in summer and shorter in winter.

40. Andrew, Simon Peter’s brother. The design of the Evangelist, down to the end of the chapter, is to inform us how gradually the disciples were brought to Christ. Here he relates about Peter, and afterwards he will mention Philip and Nathanael.

41. We have found the Messiah. The Evangelist has interpreted the Hebrew word Messiah (Anointed) by the Greek word Christ, in order to publish to the whole world what was secretly known to the Jews. It was the ordinary designation of kings, as anointing was observed by them as a solemn rite.

42. Thou art Simon. Christ gives a name to Simon, not as men commonly do, from some past event, or from what is now perceived in them, but because he was to make him Peter, (a stone) First, he says, Thou art Simon, the son of Jonah.

43. Follow me. When Philip was inflamed by this single word to follow Christ, we infer from it how great is the efficacy of the word of God; but it does not appear indiscriminately in all, for God addresses many without any advantage, just as if he struck their ears with a sound which vanished into…

44. Was of Bethsaida. The name of the city appears to have been mentioned on purpose, that the goodness of God to the three Apostles may be more illustriously displayed. We know how severely, on other occasions, Christ threatens and curses that city, (Matt.

45. Philip findeth Nathanael. Though proud men despise these feeble beginnings of the Church, yet we ought to perceive in them a brighter display of the divine glory, than if the condition of the Kingdom of Christ had been in every respect, from the outset, splendid and magnificent; for we know to…

46. Can any good thing come out of Nazareth? At first, Nathanael refuses, the place of Christ’s nativity (as described by Philip) having given him offense. But, first of all, he is deceived by the inconsiderate discourse of Philip; for what Philip foolishly believed Nathanael receives as certain.

47. Behold, one truly an Israelite. It is not on Nathanael’s own account that Christ bestows on him this commendation, but under his person he holds out a general doctrine.

48. Whence knowest thou? Though Christ did not intend to flatter him, yet he wished to be heard by him, in order to draw forth a new question, by the reply to which he would prove himself to be the Son of God.

49. Thou art the Son of God. That he acknowledges him to be the Son of God from his divine power is not wonderful; but on what ground does he call him King of Israel? for the two things do not appear to be necessarily connected. But Nathanael takes a loftier view.

50. Jesus answered. He does not reprove Nathanael as if he had been too easy of belief, but rather approving of his faith, promises to him and to others that he will confirm it by stronger arguments.

51. You shall see heaven opened. They are greatly mistaken, in my opinion, who anxiously inquire into the place where, and the time when, Nathanael and others saw heaven opened; for he rather points out something perpetual which was always to exist in his kingdom.
