Thanks, but let me recommend in return the book "How Jesus Became God" by Bart Ehrman, who's a theologian at the University of North Carolina who walks the reader through point by point why and how the Trinity was formulated in the 1st century church, with Paul"a writings very much reflecting this.
Ehrman, like myself, is a former Christian who now is more agnostic but feels there's "Something" (see my faith statement below because his approach is much the same as mine). Neither of us have any irons in this fire as we're not tied to any denomination, and both of us heavily emphasize the need to use objective history and theology as best we can and not reflect what a particular denomination might teach.
The irony is that the trinitarian concept was less controversial in the early church than it became in the following centuries. It was assumed and believed in the early church, and you can especially see it in Paul's writings, that God and Jesus are so closely linked together that goes well beyond even the relationship between God and any of the prophets, including Moses. The latter is never talked about in the scriptures like Jesus is in regards to their association with God. Nowhere does Moses make any kind of claim that he and God are basically one.
But what is also true is that the view of most in the early church was not at all well-defined, which is what largely led to the 2nd through 4th century controversies on this matter, also fueled by some "heretical" churches that claimed that Jesus was just a prophet. And just a reminder that there is nothing found in the Tanakh that states or implies that a belief in the person alone of the prophet "saves" any one. IOW, nowhere do we see anything like John 3:16 applied to any prophet, even Moses.
But thanks for the link anyway.
