“The Roman Catholic Church is a specific group with very specific rules which, if you defy, you out yourself. “
So you are saying the entirety of the Catholic Church - all members - have been cast into the outer darkness and are no longer Roman Catholics??
I find that difficult to believe.
If they remain Catholics and meet as a group, then it is a as daniel1212 has posted on numerous occasions.
No. There is obviously a difference between sinning, which everybody does, and defiantly sinning. A person could fornicate, regret it, repent, and stay Catholic. But if you declare that fornication isn't a sin because you know better than Scripture, and openly say to all and sundry that you defy the sinfulness of fornication, you've put yourself in deliberate opposition to the Church.
The most problematic aspect of all this, today, is that the hierarchy is so spineless and corrupt that they refuse to confront and address people and groups that would be have been properly dealt with in the not so distant past. Instead of making it clear that Nancy Pelosi is excommunicated, they mumble something about Pelosi excommunicating herself, and then give her communion and stay mum while she announces to the world that she's pro-abortion and Catholic.
