I wasn’t even thinking of the Catechism. I was thinking of the self-evident truth that if someone says, “I worship the Supreme Being,” he is worshiping the one, true God. If he is a Jew or a Muslim, his knowledge of God is distorted and incomplete, but he is not worshiping some other god. When a man who believes in God learns about the Trinity, he is not suddenly worshiping some different God.
I think it’s self-evident a man cannot worship a God he doesn’t know, so we don’t agree.
