I'm fairly certain it is in a Jack Chick comic book. They realized that they couldn't actually be critical of Peter, so they simply made up a different Peter to focus their bigotry on.
Their theory has a very critical flaw. If it was true, then why wouldn't the Church have simply "covered it up" by removing any reference of Simon Magus?
See post #1428. You know....I had never even heard of "Jack Chick" until I started bantering back and forth with you guys. I've still never seen one of his publications....nor do I care to.
I don't believe anyone is being critical of The Apostle Peter. We're just saying he was not one of your Popes....and was never in Rome.
