"The Jews and their High Priest didn't teach it. Jesus and the Apostles didn't teach it. Didn't become orthodoxy until 325 C.E."
"Though the Bible taught truth of the Triunity of God implicitly in both Old and New Testaments, the development and delineation of this doctrine was brought about by the rise of heretical groups or teachers who either denied the deity of Christ or that of the Holy Spirit. This caused the early church to formally crystallize the doctrine of the Triunity. Actually, Tertullian in 215 A.D. was the first one to state this doctrine using the term, Trinity."
That would be 110 years before what you claim.
Jesus said that he and the Father are one.
Look at Revelation 1:8 the Alpha and the Omega is Jehovah
Look at Revelation 22:13 the Alpha and the Omega is the First and the Last
Look at Revelation 1:17-18 the First and the Last is the living one who died and is alive for evermore.
When did the Father die?
Please understand that no one has said that Jesus and the Father are the same person but they are both God (Jehovah).
