“The grace of the Lord Jesus Christ, and the love of God, and the communion of the Holy Ghost, [be] with you all. Amen.”
If I say: “May the genius of Einstein, the philosophy of Descartes, and the strength of Schwarzenegger be with you all” does this require all three to be joined in a “Trinity”? Does it require that Einstein is Descartes (or a different “side” of Descartes)? Does it require that Descartes is Schwarzenegger (or a different “side” of Schwarzenegger)?
“Triadic formulas in the New Testament are often regarded as implying a developed doctrine of the trinity, but this is to read too much into them. 1 Cor. 12:4-6; 2 Cor. 13:14 are implicitly subbordinationist since they use the formula ‘Lord (i.e., Christ)-Spirit-God,’ differentiating the first two from God”
The Eerdmans Bible Dictionary, Editied by Allen C. Myers, p. 1020
However, even at that, we find that this verse, as was the case with so many other other similar verses of the Bible where the trinity is claimed to be “alluded to” is in fact now recognized by Christian scholars as further examples of Church efforts to insert fabricated verses into the Bible in order to make the trinity doctrine “clear” to the Bible. For example, in the Oxford Companion to the Bible we read:
“The eirliest New Testament evidence for a tripartite formula comes in 2 Corinthians 13.13, where Paul wishes that ‘The grace of the Lord Jesus, the love of God, and the communion of the Holy Spirit’ be with the people of Corinth. It is possible that this three part formula derives from later liturgical usage and was added to the text of 2 Corinthians as it was copied…”
The Oxford Companion to the Bible, Bruce Metzger and Michael Coogan, p. 782
We shall be seeing many more examples of such church “insertion” of inauthentic verses into the Bible in many more places throughout this book (read for example section 1.2.2.5).
