I am not Catholic and I think the current pope is a little "a" antichrist, not even a Christian. I don't know what you are arguing against. You are arguing against a point I didn't make and a belief I don't have.
I know my relationship with Jesus and my going to heaven has nothing to do with `another person or any human organization. That doesn't mean that we should "forsake assembling together" or that attending church is a bad thing. It does mean we need to know our Bible well so we can wisely judge what we are told by people.
