This was, of course, dramatic and revolutionary. Paul had sat through many synagogue addresses in his youth, and he must have known that people simply didn’t say this kind of thing. He wasn’t giving them a new kind of moral exhortation. He certainly wasn’t offering a new “religion” as such. He was not telling them (to forestall the obvious misunderstanding about which I have spoken already) “how to go to heaven.” He was announcing the fulfillment of the long-range divine plan.
