For there are three, &c. It is well known that the authenticity of this verse has been a subject of much controversy. “The arguments, on both sides of the question, taken from ancient Greek MSS. and versions, and from quotations made by the fathers, and from printed editions, have been stated with the greatest fidelity and accuracy by Mill in his long note at the end of John's first epistle, where he observes that this verse is wanting in all the ancient Greek MSS. of the New Testament which have come down to us, except a few, which shall be mentioned immediately. It is wanting likewise in the first Syriac, and other ancient versions, particularly the Coptic, Arabic, and Ethiopic, and in many of the present Latin MSS. With respect to quotations from the fathers, Mill acknowledges that few of the Greek writers, who lived before the council of Nice, have cited this verse. The same he observes concerning those who, after that council, wrote in defence of the Trinity against the Arians, and other heretics; which, he thinks, shows that this verse was not in their copies.” But, on the other hand, the proofs of the authenticity of this verse are,” 1st, Some of the most ancient and most correct Vatican Greek copies, from which the Spanish divines formed the Complutensian edition of the Greek Testament, and with which they were furnished by Pope Leo X.,” one of which Mill speaks of as peculiarly eminent, of great antiquity, and approved fidelity. “2d, A Greek copy, called by Erasmus, Codex Britannicus, on the authority of which he inserted this verse in his edition anno, 1522, but which he had omitted in his two former editions. This is supposed to be a MS. at present in the Trinity College library, Dublin, in which this, verse is found with the omission of the word αγισν, holy, before πνευμα, Spirit. It likewise wants the last clause of 1 John 5:8, namely, and these three are one. All Stephens's MSS., being seven in number, which contain the catholic epistles, have this verse: only they want the words εν ουρανω, in heaven. 4th, The Vulgate version, in most of the MS. copies and printed editions of which it is found, with some variations. 5th, The testimony of Tertullian, who alludes to this verse, Praxeam, c. 25, and who lived in an age in which he saith, Præscript, c. 30, the authenticæ literæ (the authentic writings) of the apostles were read in the churches. By authenticæ literæ Mill understands, either the autographs of the apostles, which the churches, to whom they were written, had carefully preserved, or correct transcripts taken from these autographs. Also the testimony of Cyprian, who flourished about the middle of the third century, and who, in his epistle to Jubajanus, expressly cites the latter clause of this verse. The objections which have been raised against the testimonies of Tertullian and Cyprian, Mill hath mentioned and answered in his long note at the end of 1 John 5., which see in page 582 of Kuster's edition. 6th, The testimony of many Greek and Latin fathers in subsequent ages, who have cited the last clause of this verse; and some who have appealed to the Arians themselves as acknowledging its authenticity. Lastly, the Complutensian edition, anno 1515, had this seventh verse exactly as it is in the present printed copies, with this difference only, that instead of these three are one, it hath substituted the last clause of 1 John 5:8, And these three agree in one, and hath omitted it in that verse. These arguments appear to Mill of such weight, that, after balancing them against the opposite arguments, he gave it as his decided opinion that, in whatever manner this verse disappeared, it was undoubtedly in St. John's autograph, and in some of the copies which were transcribed from it.”
“Instead of passing any judgment in a matter so much contested,” says Macknight, “I shall only observe, 1st, That this verse, instead of disturbing the sense of the verses with which it is joined, rather renders it more connected and complete. 2d, That in 1 John 5:9, the witness of God is supposed to have been before appealed to: If we receive the witness of men, the witness of God is greater. And yet, if 1Jn 5:7 is excluded, the witness of God is nowhere mentioned by the apostle. 3d, That in the opinion of Beza, Calvin, and other orthodox commentators, the last clause of 1Jn 5:7 hath no relation to the unity of the divine essence. If so, the Trinitarians, on the one hand, need not contend for the authenticity of this verse, in the view of supporting their doctrine, nor the Arians, on the other, strive to have it excluded from the text as opposing their tenets. 4th, That the doctrine which the Trinitarians affirm to be asserted in this verse is contained in other places of Scripture. So Wall saith. Dr. Benson likewise, in his Dissertation, written to prove this verse not genuine, saith, ‘If it were genuine, there could nothing be proved thereby but what may be proved from other texts of Scripture.'” The reader who wishes for more satisfactory information respecting the authenticity of the text, may find it in Dr. Calamy's Vindication of it, annexed to his Sermons on the Trinity, preached at the lecture at Salter's Hall, and published in 1722.
There are three that bear witness, &c. When there is a cause depending in any court, and proof is to be given in order to the decision of it, witnesses are produced, and if they are credible, and liable to no just objection, the cause is determined according to the evidence they give, unless they, to whom it belongs to determine the matter, are partial or biased. Now St. John, aiming at the establishment of those in the truth to whom he wrote this his first epistle, represents the cause depending before them as very weighty; a cause of such consequence, that it highly concerned them to weigh all matters well before they came to a determination. It was really no less a matter than whether Christianity was true or a forgery: and he intimates to them that they had very good evidence to assist them in determining. There were two sets of witnesses, the one above, the other below; and both of them unexceptionable. The one was of persons, and the other of things, which, by a figure, are represented as witnesses. The persons witnessing were, of all others in the universe, the most worthy of credit and regard, being all truly and properly divine persons, even the Father, the Word, and the Holy Ghost Persons with whom none that had the least knowledge of Christianity could be unacquainted. For these are the very persons in whose name they had been baptized, and to whom they had been most solemnly dedicated. There is only this difference to be observed, that the second witness mentioned has another name given him. In the form of baptism he is called the Son, but here the Word; a name or title which St. John seems to have taken a peculiar pleasure in giving to the Lord Jesus, for he begins his gospel with it, John 1:1, repeats it again in 1Jn 5:14 of the same chapter, and in entering upon this epistle, represents it as the great subject about which he was going to write; and mentions it again in the Apocalypse, Revelation 19:13. And as for the third witness, the Holy Ghost, he would not have been mentioned separate from the other two if he were not distinct from both. For the apostle does not speak of three names as bearing record, but three distinct persons, acting different ways and in different capacities. It is also hereby intimated that the evidence given is very full and convincing, no one of the witnesses being liable to any just objection: so that Christianity, the truth of which is so well attested, must necessarily have a firm foundation. Observe, reader, the witnesses brought forth and appealed to on this occasion, are the same that our Lord himself had mentioned as attesting his divine mission and Messiahship in the days of his flesh, as John 5:37, where he speaks of the Father that sent him as bearing witness of him; and John 8:18, where he says that he bore witness of himself; and John 15:26, where he mentions the Comforter, the Spirit of truth, as testifying of him. Accordingly we learn from the gospel history, 1st, That the Father bore witness to Jesus with an audible voice three sundry times; first, when he was baptized, Matthew 3:16-17; a second time when he was transfigured, Matthew 17:5; and a third time after he had raised Lazarus from the dead, when many flocked out of Jerusalem to meet and applaud him, John 12:28; and the two former of those times, the testimony borne is the same with that here mentioned by St. John, 1 John 5:1; 1 John 5:5, namely, that Jesus is God's beloved Son, and therefore the true Messiah and Saviour of the world. 2d, The Word made flesh, the Lord Jesus himself, several times bore the same testimony; as, for instance, to the woman of Samaria, John 4:26; to the Jews, John 8:24; John 8:58; John 10:30; John 10:36; and especially when adjured by the high-priest, in the name of the living God, to tell them whether he was the Christ, the Son of God, Matthew 26:63; Mark 14:61. And he, in effect, bore the same testimony when he showed himself to dying Stephen, as standing at the right hand of God in all the splendour of the divine glory, when he appeared to Paul on his way to Damascus, surrounded with a light above the brightness of the sun, and when he manifested himself to John in the isle of Patmos, to give him the wonderful visions contained in the Apocalypse. And, 3d, The Holy Ghost in many ways bore the same testimony, as by his descending on Jesus immediately after his baptism, and in a glorious manner remaining on him, John 1:32-33, and working miracles by the disciples sent out during his life: by coming down on the apostles in fiery tongues ten days after our Lord's ascension, thereby publicly declaring to all present, and to all to whom a well-attested account of that fact should come, that he really was the Son of God, exalted to the right hand of the Majesty on high; a truth which these same apostles boldly testified from that day forward in Judea, and all the world over. Thus we see what the apostle means when he says, the Father, the Word, and the Holy Ghost witnessed in heaven. Or, as the words may be rendered, there are three in heaven that bear, or that bore witness, (for μαρτυρουντες is a participle of the imperfect as well as of the present tense,) distinguished from the other three witnesses mentioned in the next verse, that are on earth. The meaning is, not that they bear, or bore, witness to the angels and blessed spirits that are in heaven, but only that they speak from heaven, while the others speak on earth. They witness while they are in heaven, notwithstanding that they are so much above us, and so far distant from us: and therefore the testimony they bear is to be the more regarded, and we shall be the more inexcusable if we do not acquiesce in it, and improve by it.
And these three are one The word is not εις, one person, but εν, one thing, expressing evidently the unity of the three, and that not only as to their testimony, but also and especially with respect to their nature; it being evident, from a variety of other texts, that each of the three is truly and properly God, as has been abundantly proved in the course of these notes. If unity of testimony had only been intended, it is probable the expression would have been as in the close of the next verse, where the three witnesses on earth are spoken of, these three εις το εν εισιν, agree in one.
