I was raised in a Protestant home on the South/Southwest side of Chicago, 1960s & 70s. Most of the other kids in my neighborhood were either "nothing" or Catholic.
I remember hearing about what my Catholic friends were taught at their schools and by their parents. I remember my mom telling me that Catholics are Christians. But that never matched up in my head. To me, being Catholic was just following a bunch of man made rules. That's what Jesus criticized the Pharisees for doing.
And my Catholic friends didn't really know what was in the Bible. They went to CCD classes and learned about Catholic Saints and stuff. All of the ceremonial things were important. All based on works instead of faith.
This whole thing with the Pope and the Catholic Church seems like it is just used to control people.
