Father Powell: You don't believe?

Grissom: In religion. I believe in God, in science, in Sunday supper. I don't believe in rules that tell me how I should live.

Father Powell: Even if they're handed down by God?

Grissom: How many crusades were fought in the name of God? How many people died because of someone's religion?

Father Powell: Fanaticism, not religion.

Grissom: Semantics. They're still dead.
