After three centuries of competing ideas about what the new Christianity was about, the “Fathers” of the church ? (there were no mothers admitted) got together and constructed a mishmash of bits and pieces taken from other cults and beliefs and told the world “This is Christianity.  This is what to believe. Argue at your peril”.   For centuries after that dissidents tried to inject precepts they thought Jesus would have approved of, but these dissidents were promptly excommunicated or burnt at the stake. Christianity, as taught by the current Catholic hierarchy, is all about control. If you wish to believe what the Vatican tells you, that is your privilege. The rest of us prefer to think for ourselves, but, unlike others, tolerate the beliefs of others!
