From the current First Things:
Mormon beliefs diverge widely from historic Christian orthodoxy. The Book of Mormon, which is Mormonism’s principal source for its claim to new revelation and a new prophet, lacks credibility. And the Jesus proclaimed by Joseph Smith and his followers is different in significant ways from the Jesus of the New Testament: Smith’s Jesus is a God distinct from God the Father; he was once merely a man and not God; he is of the same species as human beings; and his being and acts are limited by coeternal matter and laws.
The intent of this essay is not to say that individual Mormons will be barred from sitting with Abraham and the saints at the marriage supper of the Lamb. We are saved by a merciful Trinity, not by our theology. But the distinguished scholar of Mormonism Jan Shipps was only partly right when she wrote that Mormonism is a departure from the existing Christian tradition as much as early Christianity was a departure from Judaism. For if Christianity is a shoot grafted onto the olive tree of Judaism, Mormonism as it stands cannot be successfully grafted onto either.
