Those who say the Church should not tell people how to act are actually presuming to tell the Church how to act. Shall we call it secular humbuggery, a key to the contradictions of "the age of reason."
Indeed, the age of reason has proven quite irrational in it's sundry supposedly foundationless dogmatisms. That is why every man needs the Pope! That is why the Pope is called "Peter" (Rock); he provides the only sure foundation in the world: Christ.
