"If the doctrine of the Trinity were true, and required to believe upon for salvation itself, it may be pointed out that it is utterly unique in the sense that all other essential Christian doctrines are taught plainly in the Bible, whereas the Trinity is somehow derived from "all of what the Bible teaches." In this regard, the Trinity (and associated concepts) would prove to be the only essential though non-articulated, unannounced doctrine of the Christian faith, based on a consideration of Scripture. But as adamant and forceful as Evangelical scholars have expressed themselves with respect to the centrality of the Trinity and the absolute necessity of its acceptance, the Bible itself never identifies the one God as the Trinity, but as "the Father"; nor does there exist one example in all of the Scriptures where the term "God" or the name "YHWH" can be proven to represent the entire "tri-unity of persons" of the "Godhead." Any kind of attempt would be an exercise in speculations at best. Unfortunately, defenders of Trinitarian dogma have failed to fully come to terms with the implications of these facts. Consider carefully: If the doctrine of the Trinity is true and essential to Christianity as is claimed, the Bible itself (the very documents upon which Christianity is based) never defines or proclaims who or what the one God is according to his (or its?) most basic, fundamental characterization -- the very meaning of "God" in its most distinguishing sense. This is altogether incredible." --Patrick Navas
