I agree with what the others have said. For me, religion is an intensely personal thing. I come from a long line of Baptists, although my personal views (incidentally, shared by most of my family) would make the more conservative elements of that church cringe and pop blood vessels.
I attend church occasionally, but I take out of it the lesson that I know in my heart is right and leave the parts that I don't agree with, chalked up to the other fella's opinion. I have found that I can learn from almost any religion and find the good in it and sort out the bad, or the things that just don't fit into my life.
I have frustrated the heck out of several folks with a missionary bent who have tried to sway me one way or another to what they feel is the best or true religion. My point to them has been that if the light does not shine through in your day to day life, words alone cannot convince me, or others to follow. I can respect and admire anyone who leads a good, moral, decent life regardless of where they go or don't go to church, mosque, synagogue, etc... To me, the goodness and kindness in a person's heart is so much more important than what religion they proclaim to be. There are good, kind people who practice all religions, and some, none at all.
So, for me, the one true religion is the one I have in my heart, the one that works for me. It encourages me to be the best person I can possibly be and to help those in need. It may not be in any theology texts, it may not be extolled by men of the cloth, but it is the right one for me. =)
