1 John 5:7

“For there are three that bear record in heaven, &c.] That is, that Jesus is the Son of God. The genuineness of this text has been called in question by some, because it is wanting in the Syriac version, as it also is in the Arabic and Ethiopic versions; and because the old Latin interpreter has it not; and it is not to be found in many Greek manuscripts; nor cited by many of the ancient fathers, even by such who wrote against the Arians, when it might have been of great service to them: to all which it may be replied, that as to the Syriac version, which is the most ancient, and of the greatest consequence, it is but a version, and a defective one. The history of the adulterous woman in the…”

“three--Two or three witnesses were required by law to constitute adequate testimony. The only Greek manuscripts in any form which support the words, "in heaven, the Father, the Word, and the Holy Ghost, and these three are one; and there are three that bear witness in earth," are the Montfortianus of Dublin, copied evidently from the modern Latin Vulgate; the Ravianus, copied from the Complutensian Polyglot; a manuscript at Naples, with the words added in the Margin by a recent hand; Ottobonianus, 298, of the fifteenth century, the Greek of which is a mere translation of the accompanying Latin. All the old versions omit the words. The oldest manuscripts of the Vulgate omit them: the earliest…”

“For there are three that bear record in heaven ... - There are three that “witness,” or that “bear witness” - the same Greek word which, in 1 John 5:8, is rendered “bear witness” - μαρτυροῦντες marturountes. There is no passage of the New Testament which has given rise to so much discussion in regard to its genuineness as this. The supposed importance of the verse in its bearing on the doctrine of the Trinity has contributed to this, and has given to the discussion a degree of consequence which has pertained to the examination of the genuineness of no other passage of the New Testament. On the one hand, the clear testimony which it seems to bear to the doctrine of the Trinity, has made that…”

“What Bengelius has advanced, both concerning the transposition of these two verses, and the authority of the controverted verse, partly in his "Gnomon," and partly in his "Apparatus Criticus," will abundantly satisfy any impartial person. For there are three that testify - Literally, testifying, or bearing witness. The participle is put for the noun witnesses, to intimate that the act of testifying, and the effect of it, are continually present. Properly, persons only can testify; and that three are described testifying on earth, as if they were persons, is elegantly subservient to the three persons testifying in heaven. The Spirit - In the word, confirmed by miracles. The water - Of…”

“5:7-8 three witnesses: The Spirit descended on Christ at his baptism (see John 1:32-34). The water is the water in which Christ was baptized (see Matt 3:13-15; Mark 1:9-11). The blood is the blood that Christ shed at his crucifixion (see Mark 15:37-39). All three proclaim Jesus as God’s Son (1 Jn 5:6). • After the phrase three witnesses, a few very late manuscripts add in heaven—the Father, the Word, and the Holy Spirit, and these three are one. And we have three witnesses on earth. The longer version was written in Latin several centuries after John to explain the three elements (water, blood, and Spirit) as symbols of the Trinity. This explanation found its way into some Latin editions of…”
