Can a murderer still be a member of the catholic church? Are you not aware that the Church contains both the good and the wicked? Until they slide off into formal heresy and schism, they are still members, though wicked, dead pretenders and liars. St. Augustine listed quite a few more criminals as within the Church. A list that would surely scandalize. If you conceive of the Church as an external, public society, as is defined Catholic doctrine, this will be more easily realized. The Church as the Kingdom of God is as tangible as the Kingdom of France as Bellarmine would say. At any rate, I see their heresy and schism being consumated in the near future.
