As a conservative biblical Christian I just do not know of any Christian denomination that is orthodox, mainline or any denomination of note that shares your particular view on the Godhead.
That still only make up about 30% of the world's population assuming that the majority even think about the issue which is doubtful. But even if we take your point and go along with your assertion and assume that the majority of Christians share your beliefs, you are still left with having to explain the multitudes of different beliefs, interpretations and contradictions; these beliefs come from the same source material and most importantly they were only politically promulgated approximately 300 years after Christ's death by a politician.
I'm happy to expand on some of this if you want me to.
