Unbelievers! how do you recognized them?are those that follows doctrines of men belongs to unbelievers?

Without the Roman Catholic Church and the Jews to begin Christianity, you wouldn't have whichever cheap sect of Christianity you believe in (because any serious Christian Church would teach love and respect for one another). Anyways, instead of worrying about religion, which seems a topic much too elevated for you, why don't you go back to your middle school grammar cl (if you've made it that far?).
