MORE ON FRANK PAGE'S DISSERTATION

I'm just thinking out loud here. Frank Page, the new president of the SBC, has disavowed his doctoral dissertation. He said the theology of it was wrong. But, Page was awarded his Ph.D. based on it. If it was manifestly and theologically wrong, should he forfeit the doctorate based on it? It seems a little weird that you could be awarded a doctorate on the basis of bad theology, but still be called doctor.
