First Reading · 1 John 5:5-13

5Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?6This is he that came by water and blood, Jesus Christ: not by water only but by water and blood. And it is the Spirit which testifieth that Christ is the truth.7And there are Three who give testimony in heaven, the Father, the Word, and the Holy Ghost. And these three are one.8And there are three that give testimony on earth: the spirit and the water and the blood. And these three are one.9If we receive the testimony of men, the testimony of God is greater. For this is the testimony of God, which is greater, because he hath testified of his Son.10He that believeth in the Son of God hath the testimony of God in himself. He that believeth not the Son maketh him a liar: because he believeth not in the testimony which God hath testified of his Son.11And this is the testimony that God hath given to us eternal life. And this life is in his Son.12He that hath the Son hath life. He that hath not the Son hath not life.13These things I write to you that you may know that you have eternal life: you who believe in the name of the Son of God.

commentary

The Douay has it is the Spirit which testifieth that Christ is the truth (v. 6), rendering the Latin quoniam Christus est veritas; Haydock's bibliographical note records that most Greek copies now read oti to pneuma esti e aletheia, quoniam Spiritus est veritas — "that the Spirit is the truth." A second wobble sits two verses later. Against hi tres unum sunt in v. 8 the same note reports that divers Greek copies have eis en eisin, in unum sunt, which is why the Protestant version reads "these three agree in one" here while keeping "are one" at v. 7, where the Greek stands as kai oi treis en eisi. The two halves of the passage are built to rhyme — three witnesses in heaven, three on earth — and the manuscripts are least steady at precisely the point of the rhyme.

Witham, whom Haydock prints at length, takes the objection head-on: the Socinians urge that v. 7 is wanting in many Greek manuscripts, and Erasmus in one edition and Richard Simon in his Critics questioned or rejected it. His answer is mechanical before it is doctrinal. Verses 7 and 8 begin and end with the same words, so a transcriber's eye slips from one to the other and drops a line; that a whole verse should be added is not credible. Then the citations: and these three are one is quoted by Tertullian contra Praxean xxiii and twice by Cyprian — the letter to Jubaianus and De unitate Ecclesiae — both writing long before the Arian dispute, with Fulgentius later using the verse against the Arians and Dr. Fell defending it as genuine. The silence of Athanasius proves only that the omission had already entered some copies. What the defence secures is a distinction Challoner then draws sharply: the heavenly Three are one in nature, in substance, and in all perfections, as when Christ says I and the Father are one, while the earthly three — the spirit yielded with a loud cry, the water and the blood from the pierced side — are one in that they agree in a single testimony, and what they testify to is his humanity. Witham reads the "spirit" of v. 6 the same way: not the Holy Ghost, who is named in the next verse, but either Christ's own soul commended to the Father, which showed him truly man against Cerinthus, or the spirit of grace that bears witness with our spirit (Romans viii. 16).

The passage rebukes two opposite refusals, and both are still current. Cerinthus would not have a God who bled; the Socinians would not have the Son they could not fit into a manuscript count. Between them stands v. 10: he that believeth not the Son maketh him a liar, because he will not receive testimony God has already given. The believer is not asked to adjudicate the apparatus but to hold what Witham says is lodged inside him — the testimony of God in himself, showing itself in the confidence that asks and expects to receive, with perseverance and in the manner we ought. Everything the argument defends is finally attested by two ordinary fluids running from a dead man's side.

First Reading 1 John 5:5-13

Haydock Catholic Bible Commentary · Public Domain
5:6 · bibliography — editions & variants cited above

Came by water and blood. The sense seems to be, by water, with which he ordered every one to be baptized and made Christians; 2ndly, by his blood shed on the cross for our redemption. (Witham) --- Blood: not only to wash away our sins by the water of baptism, but by his own blood. (Challoner) --- And it is the Spirit that testifieth that Christ [2] is the truth. By the Spirit, which is not here called the Holy Spirit, or the Holy Ghost, as in the next verse, is either meant the Spirit or soul of Christ, which dying he recommended into the hands of his Father, and which shewed that he was truly man, against Cerinthus, and some heretics of those times; or else it may signify the spirit of grace, given in this world to the faithful, in the same sense as St. Paul says, (Romans viii. 16.) that the Spirit himself giveth testimony to our Spirit, that we are the sons of God: and of which may be understood what is said here, (ver. 10.) He that believeth in the Son of God, hath the testimony of God in himself. (Witham)

Quoniam Christus est veritas; in most Greek copies is now read, Greek: oti to pneuma esti e aletheia, quoniam Spiritus est veritas.

5:7

There are three that give testimony in heaven: the Father, the Word, and the Holy Ghost; and these three are one: i.e. one in nature, in substance, and in all perfections, in the same sense as when Christ himself said, (John x. 30.) I and the Father are one, or one thing. The Socinians object that this verse is wanting in many Greek manuscripts; and even Erasmus in one edition, and Mr. Simon in his Critics, have questioned it, or rejected it, as a false reading, but without any sufficient proofs and grounds, as hath been shewn by many learned Catholics, and also by Protestant writers, who receive in their translations this verse as canonical. It is easy to account for the omission of this verse; for as both the seventh and eighth verse begin and end with the same words, this gave occasion to the oversight and omission of the transcribers, whereas it is not credible that such a whole verse could be added. And that it was only by the mistake and oversight of transcribers may further appear, because we find part of the seventh verse, to wit, and these three are one, cited by Tertullian, lib. cont. Praxeam. chap. xxiii. p. 515. Ed. Rig. and twice by St. Cyprian, Epist. 73. ad Jubaianum. p. 125. Ed. Rig. in the Oxford Edition, p. 310. and in his Treatise de Unit. Ecclesiæ, p. 181. Ed. Rigal. and in the Oxford Ed. p. 79, where also Dr. Fell defends this verse of St. John to be genuine. Tertullian and St. Cyprian wrote long before the dispute with the Arians. The Socinians also object that this passage is not brought by St. Athanasius and some other fathers against the Arians, which they could scarce have omitted had they read this verse, but this only proves that this omission had happened in some manuscripts in their time, or, as some conjecture, that the Arians had corrupted some copies. St. Fulgentius made use of it against the Arians, and also others about that time. See the Benedictines of St. Maur against Mr. Simon, in the first tome of St. Jerome, p. 1670. Both Catholics and Protestants, after diligent examination, have received this verse, which is found in the best manuscripts. See Greek Testament at Amsterdam, in the year 1711. The three divine Persons, who are present everywhere, though said to be in heaven, gave testimony concerning Christ. The Father by a voice from heaven, both at his baptism (Matthew iii. 17.) and at his transfiguration, (Matthew xvii. 5.) saying: "This is my beloved Son, in whom I am well pleased, hear ye him:" and also by all the miracles wrought by the same power of all the three divine Persons. 2. The Son testified to the Jews on many occasions, that he was sent from God, that he was the only Son of God, that he and his Father were one, &c. as in the annotations on John iii. The Holy Ghost confirmed the same, particularly by coming down upon the disciples on the day of Pentecost, and inspiring them to teach the same doctrine concerning Jesus Christ. (Witham) --- An express proof of the three distinct persons and unity of nature and essence in the blessed Trinity.

5:8 · bibliography — editions & variants cited above

And there are three that give testimony on earth: the Spirit, the water, and the blood; and these three are one.[3] This is a repetition of what was before said, ver. 6, to be expounded in the same manner. But when it is added, these three are one, the sense is, that they witness one and the same truth. (Witham) --- As the Father, the Word, and the Holy Ghost, all bear witness to Christ's divinity; so the spirit, which he yielded up, crying out with a loud voice upon the cross, and the water and blood that issued from his side, bearing witness to his humanity, and are one; that is, all agree in one testimony. (Challoner)

Hi tres unum sunt. Divers Greek copies, Greek: eis en eisin, in unum sunt: and so the Protestant translation hath, and these three agree in one; though in the seventh verse they follow the manuscripts which there have, are one, Greek: kai oi treis en eisi.

5:10

He that believeth not the Son, maketh him (God) a liar, by refusing to believe the testimonies given by the three divine Persons, that Jesus was the Messias and the true Son of God, by whom eternal life is obtained and promised to all that comply with his doctrine. In him we have also this lively confidence, that we shall obtain whatever we ask, according to his will, when we ask what is for our good with perseverance and in the manner we ought. And this we know and have experience of, by having obtained the petitions that we have made. (Witham)
