Several other religions feel that if you aren't one of them you will burn in h*ll.
True, but with Christianity there is one unifying law--The Bible. It doesn't matter if you're Catholic, Protestant, Lutheran, Episcopalian, Methodist, etc., the Bible clearly says that if you believe in Christ as the Son of God and our Savior, then you will be saved and achieve eternal life.
Only when certain people get involved do these basic rules change. That is why Catholics have had problems with child molesters and Episcopalians have had problems with gays. People step into a simple formula for success and totally screw it up.
