All things which existed before the Protestant Reformation. Branching off from an entity and then claiming you are the entity is nonsensical. It would be like Sheaus and Randy Orton leaving the WWE, starting a promotion and then claiming they are the true WWE. We'd laugh at those people. I have no problem at all with sects branching off from the Catholic Church and claiming they are also Christian. But to branch from the church and then claim the original church wasn't the TRUE Christian is nothing more than thinly veiled propaganda. Outside of the stupid people, no. While Catholicism certainly has its faults, both currently and historically (lots of them, in fact), having grown up in a Catholic church and visiting numerous Catholic churches over the years, the one thing I've never heard from any of them is the idea other churches who claim to be Christian are just pretenders. In my experience, it is only Protestants who have been so arrogant to make such a claim (and I have seen firsthand said arrogance, from the church my grandparents used to attend, no less). Catholics are Christian. They were Christian before the Protestant Reformation. To be a Christian essentially means to believe in Christ and his teachings (and historically, through baptism), things which the Catholic church was doing from the very beginning. So no, there is no logical way to claim Catholics are not Christian, unless one is completely closed minded, completely immune to the idea that even a slight variation of what they believe can still be considered Christian. No, they are not. Catholicism is not a different religion from Christianity, whether in history or in practice. That doesn't make sense. When you went to a Catholic church, you went to a Christian church. Perhaps you now attend the church of a different sect of Christianity, but you've always went to a Christian church. Exactly.
