"Wow! I thought that was insight reserved only to God."
No, that's only reserved for Catholics who believe that those who aren't are going to hell.
Your sarcasm aside; I don't speak for all Catholics of for the Catholic Church, but I certainly don't believe as you might think. After all, I have a brother who is a Protestant minister. And, I know many good Christians who are not Catholic, and that God knows who are his servants.
