This is the Catholic point of view, then, now and always.
There is a church, it is a community, and going it alone isn’t a good thing. If you want to go personally mystical that’s fine, but coming back afterwards with “God told me this..” is problematic.
Scripture states that WE the believers in Christ ARE His church, not some building.
I don’t know anyone who believes we are to go it alone. That said, a church member who doesn’t know HIM personally is nothing but a tare in the wheat field. Church membership cannot save you because salvation is individual, not corporate. No priest or pope will be there to plead your case when you stand at the bar of judgment.
That is correct.
Vatican II has not revoked a teaching that outside the Church there is no salvation. The logical conclusion is that Jesus is not fully personally present to those who are outside the Church.(Eph 2:11-13) Since the Church is nourished as the body of Christ.(Eph 5:29)
Therefore, to be outside is not to be fully nourished by the power of Christ.
What Church did the thief on the Cross that established a sincere relationship with Christ go to?
