How can finite man commune with an infinite God? To both Christians and Jews, God himself has made that possible by irrupting into the temporal world. To Christians, God became man in the Incarnation; to Jews, the God that spoke out of the fire on Mount Sinai gave his Torah.
Even as Jews and Christians profoundly disagree about the truth, they are united in the belief that there is a truth to be sought.
If Christians see Mormonism as a dramatic deviation from a millennia-old, biblically-based faith, Jews see Christianity in the same light.
While Jews and Christians both agree on many religious issues, we disagree, and believe each other profoundly wrong, about others.
Traditional Christians cannot conceive of God as Mormons do: a God who has a wife, who invites other human beings to become gods with him.
