Do you believe that only Catholics staying with Jesus can attain eternal bliss?
What will happen to the Jewish, Protestants, Muslims, Buddhists, etc., that are all living pious, generous, giving lives? They cannot attain eternal bliss?
What about Athiests, or non-religious people living in famine and poverty in third world countries, but they live a life of Jesus, even though they’ve never heard of him? Can they not live in eternal bliss?
If they can’t attain eternal bliss, where do they go?
You didn't answer my question but I'll answer yours.
Non-Catholics can certainly be saved.
