Is catholicism (how ever it's spelt) a tool for the devil?

Jesus Christ, in His Revelation to John, gave seven separate messages to the seven churches that make up His total body (The Church). I believe one of those is to the Holy Roman Catholic Church. No, they are not Satanic. Peter, the Apostle, established the Catholic Church by the Word of Jesus Christ. There will be a multitude raptured, and members of the Catholic Church will be among them. After the Rapture, take heed that no man deceives you.
