I don’t even know what the basics of christianity are anymore. Do you teach it is a monotheistic religion or a polytheistic religion that changed its mind. Do you teach it as them believing humanity stemmed from adam and eve, or adam and eve were the first christians and their 3 sons were to spread the beliefs but acknowledge that humans already existed on earth created by other gods/means. You break bread and it is literally the body of a man, or figuratively. 40,000 versions of christianity that found reasons to not be the same sects. So I suppose you teach a historical touching of how it has changed but by no means could you teach the concepts of Jesus before highschool without upsetting parents these days, even then. Imagine the response to forgiving all drug users, imprisonment being wrong, not having any spending money, etc. Angry parents pissed off claiming schools are teaching Jesus was “some sort of communist.” Was banking not against christian law as well, as you could not ask for interest and such as a true christian would have given it to you without expectation?
