Once I had a chat with a catholic couple. They were not the kind of people with a bible and a cross in their hands, trying to enroll you, but their lives seemed to be ruled very strictly by their belief. And so, they were shocked by one of my sentances. I claimed that if we were all sons of God, even people like Stalin (kidding on the fact that a communist leader is thought to be no believer) has his place in Heaven... All the worst bastards on earth being sons of Him.
They concluded later our chat by this : "If you do not believe in God, you cannot not believe in ghosts"...
Still thinking about this sentance...
