The Catholic Church may be one thing but the individuals are spread out quite a bit. You have Traditionalists who reject the recent popes, Traditionalists who accept recent popes but not pope Francis, Traditionalists who accept even the current pope, conservatives of several varieties who are not Traditionalists, charismatics, all sorts of middle of the road people, liberals of all stripes including promoters of contraception, abortion, and/or a homosexual agenda. Some times these groups line up with secular political agendas and parties, but sometimes not. Not all are in good standing but may call themselves Catholic to advance their agendas. The group 'Catholics for a Free Choice' is one of those, a group that promotes abortion. But then on the other side is a tiny fringe group following 'Pope Michael'.
Catholic teaching is fairly represented in the Catechism of the Catholic Church. One ought to stay close to that. Not that everyone does.
