What's the difference, actually, between believing in a God on one side or the other, Catholic or Protestant? It's all the same if you accept it. Much of our morality is based on things completely outmoded. But people are wonderful. There's no harm in them, they're not the problem. It's governments and politics that make wars and do stupid things, and they should be attended to. There's no security in this life.
