Ekklesian, I am taking an unexpected direction here. Around 50 years ago, I read a short testimony by a Catholic priest who had converted to Russellism (They call themselves "Jehovah's Witnesses") He stated that in seminary, they made it clear to the students that the Bible did not teach the Trinity, and therefore, the Catholic Church was lying to its lay people.
Now, as much as I despise Catholicism (but not Catholics), I also reject idealism--the belief that any evil that helps my cause is good, and any good that weakens my cause is evil. It is not necessary to slander the Catholic Church; both the Bible and history strongly demonstrate the evil of Catholicism.
While many Catholics are unaware of it, the Catholic Church officially teaches that the word "Trinity" is not in the Bible, and that the Trinity is a man-made explanation of something that God said is unexplainable.
