Wow, ansel12, I never knew all that. And people say Catholicism is weird!
Here is a taste of the Catholic take on Mormonism from ‘Catholic Apologetics’.
ARE THE MORMONS CHRISTIAN?
No. Mormons are not Christians. The Mormons will claim to be Christian because they claim to follow Christ, and believe in the Bible. They say that Jesus is a god, but not THE God. They also believe that Lucifer is the brother of Jesus.
WHAT DO MORMONS BELIEVE?
Even God was once a Man like ourselves who evolved into a god.
By following all the rules and ordinances of God here, Mormon men and women have the potential of also becoming gods. “As god once was, man is. As God is, man may become” (Joseph Smith’s words). Mormons believe that there are many worlds and many gods. Each god is similar to God the Father, having the same powers and omnipotence, and even being able to create their own worlds. “Heavenly Father” is only the name of the god who rules over this world.
