When I believed the bible was the inerrant word of god, I thought the JW out up a good argument against the trinity. Then I realized what Christian churches actually teach and I saw that there were real reasons for both sides opinions. Then I realized the bible wasn't historically reliable, nor was it talking to our ideas of truth, fact and that we were indeed unable to ignore the historical church in coming to an understanding of "truth". Then I threw up my hands and figured that if God expected me to figure it out, it wouldn't be debatable.
If there is a God he either wasn't the author of that mess or if he was, there is no chance of getting to any absolute truth and it's impossible to please the conflicted master of the universe, so why try?
