I am sure many members of the Roman Catholic church believe they are Christians, but many of the teachings of the church is directly opposed to the Bible, but they don't know that because they're not encouraged to study the Bible for themselves. The leadership though, is straight from the pit of hell.

I completely believe the pope (this one or the next) will fill the role of the false prophet in Revelation, introducing and endorsing the one world leader who will turn out to be the anti christ.
