This was a debate among the early Christian writers (before the word Catholic was even used). What God does with us after death is unknowable to us, period. Salvation, as in the sacrifice of Jesus to feel what we feel is for THIS life. These folks probably think themselves saved, but I doubt they have forgiveness and love in their hearts. If they do, it is cheap grace. You can't have that much hate in your heart can really know Jesus. They are certainly not doing the work of the Kingdom of God in a way that shows they are radicalized into it. Salvation quiets the heart. I don’t see it in them.
