Which Church is the TRUE Church of God - Catholics or Mormons?

Where do you think it tells you that it's clear that Jesus wanted us to join one church and that being His church. Most all of us belong to His church. What do you think is His church? Jesus wanted us to believe in His Father. As long as we learn and teach from His Bible, we belong to His church. There are many who do this with very small differences in belief. The Catholics are furthest out of the mold even though they are a very old church. They place a very large emphasis on Mary, Mother of Jesus. The Protestants don't do this because it's not Biblical. Mankind is so very good at adding in to what they think God would have wanted instead of what He said. We need to be very careful about that. My church doesn't even have any images of Jesus or other things because we were told not to do that. Again, the Catholics have their Crucifix. I'm a Southern Baptist.
