" In the beginning, God was simply the most powerful god among many. He is just a local tribal god. And then in the sixth century, when the Jews were in Babylon, the notion of a world savior came in, and the biblical divinity moved into a new dimension. You can keep an old tradition going only by renewing it in terms of current circumstances. In the period of the Old Testament, the world was a little three-layer cake, consisting of a few hundred miles around the Near Eastern centers. No one had ever heard of the Aztecs, or even of the Chinese. When the world changes, then the religion has to be transformed. "
