In his book Like the Flowing River, Paulo Coelho talks about "The Catholic and the Muslim."
I was talking to a Catholic priest and a young Muslim man over lunch. When the waiter came by with a tray, we all helped ourselves, except the Muslim, who was keeping the annual fast prescribed by the Koran.
When lunch was over and people were leaving, one of the other guests couldn't resist saying: "You see how fanatical these Muslims are! I'm glad to see you Catholics aren't like them."
"But we are," said the priest. "He is trying to serve God just as I am. We merely follow different laws." And he concluded: "It's a shame that people see only the differences that separate them. If you were to look with more love, you would mainly see what we have in common, then half the world's problems would be solved."
