Which denomination of Christianity then is "true"? Is it Catholicism? After all, there are conflicts between Catholicism vs. Lutheranism, vs. Baptist, vs. Presbyterian, vs. Methodist, vs. Gnostic, vs. Unitarian... and of course Latter-Day Saints.

Pretty serious conflicts in fact, sometimes more serious than say vs. Judaism.

Which one in your opinion should be respected, so all others that are known or believed to be outrightly false, can be openly disrespected the same as Islam and Jainism?
