I listened to the sermon, and I remember complete astonishment because what they were talking about were things that were just crazy. It was communion time, where you eat this wafer and are supposed to be eating the body of Christ and drinking his blood. My first impression was, "This is a bunch of cannibals they've put me down among!" For some time, I puzzled over this and puzzled over why they were saying these things, because the connection between what they were saying and reality was very tenuous. How the hell did Jesus become something to be eaten?
I guess from that time it was clear to me that religion was largely nonsense--largely magical, superstitious things. In my own teen life, I just couldn't see any point in adopting something based on magic, which was obviously phony and superstitious.
