If we do not get a new Pope and a strong Conservative Pope soon I fear a major schism.
We need not change the Church. There are plenty of dying Protestant churches people can be openly divorced, remarried and even involved in church sponsored sodomy. The Church of Rome need not find room for them in their pews.
It is difficult to get to Heaven. Most of us will not. That is written. Without following the faith, we are doomed to eternal damnation. Bishops are double damned when they deny the teachings of Christ and his Church.
The church has been through much worse than this. Believe it.
What would be an example of the Church being through much worse than the post Vatican II era? I think the closest would be the Arian days, but even then no Church Council jump started that mess.
The Catholic Church welcomes you!
