Accusations have been made that 1 John 5:7 was added to scripture. 1 John 5:7 For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one. http://www.scionofzion.com/1_john_5_7.htm There were reports that Arians which denies the deity of Christ had almost won in the western part of the Roman Empire in taking over the church whereas a small handful of loyal disciples managed to stem the tide. One can surmise that all Greek documents, if any, were destroyed that contained that disputed 1 John 5:7 which would explain its re introduction in Latin only. While in the eastern part of the Roman Empite, the Byzantines, had been combatting Sabellianism. Its removal could be seen as deemed necessary if it wasn't an excuse by covert Arians to do so. Now those oppose can balk at this, but let us consider this line of reasoning; If 1 John 5:7 is not in the majority of manuscripts, is it in the minority of manuscripts to give some realm of plausibility? Yes. How can we know for sure that the disputed 1 John 5:7 belongs there? By earlier writings testifying to its existence as it is written. AND All quotes from that link BTW So let us read the verse in context. 1 John 5:6 This is he that came by water and blood, even Jesus Christ; not by water only, but by water and blood. And it is the Spirit that beareth witness, because the Spirit is truth. 7 For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one. 8 And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one. 9 If we receive the witness of men, the witness of God is greater: for this is the witness of God which he hath testified of his Son. The witness in earth of the witness of men giving testimony that Jesus was born of water and of blood as the Holy Spirit leads them to witness is the witness of men. If you remove 1 John 5:7, then where is the witness of God in being greater than the witness of men in verse 9? So the disputed 1 John 5:7 belongs there in the scripture.
