>>There are lot of Catholics who have said that non Catholics are probably going to hell. Which is part of their theology<<
No it isn’t part of the Catholic theology.
“In fact the Spirit of Christ has not refrained from using them [i.e. Protestant churches] as instruments of salvation, whose value derives from that fullness of grace and of truth which has been entrusted to the Catholic Church”
What you are stating is a myth. Have you ever been told by a Catholic that you are going to hell?
Granted, the FReepers that have said this on the Religion forum have often been attacked by other Catholics, or been SSPX members who are in schism. But it has happened, and is one of the reasons many of the Orthodox are no longer on FR.
I know what current Catholic theology is, and know that it has changed in emphasis over the years. I also know the same to be true for most Lutheran synods. Since we stopped shooting each other and realized that islam and the secularists were a much bigger threat, the family quarrel has dropped off the radar screen.
