Heresy is like cancer. It needs to be cut off and cast aside in order for the rest of the body to remain healthy.
Just keep this joke in mind:
"I was walking across a bridge one day, and I saw a man standing on the edge, about to jump off. So I ran over and said "Stop! don't do it!"
"Why shouldn't I?" he said.
I said, "Well, there's so much to live for!" He said, "Like what?"
I said, "Well...are you religious or atheist?" He said, "Religious."
I said, "Me too! Are you Christian or Buddhist?" He said, "Christian."
I said, "Me too! Are you Catholic or Protestant?" He said, "Protestant."
I said, "Me too! Are you Episcopalian or Baptist?" He said, "Baptist!"
I said, "Wow! Me too! Are you Baptist church of god or Baptist church of the lord?" He said, "Baptist church of god!"
I said, "Me too! Are you original Baptist church of god, or are you reformed Baptist church of god?" He said, "Reformed Baptist church of god!"
I said, "Me too! Are you reformed Baptist church of god, reformation of 1879, or reformed Baptist church of god, reformation of 1915?" He said, "Reformed Baptist church of god, reformation of 1915!"
I said, "Die, heretic scuм," and pushed him off.
