Because of a certain person who shall go nameless — let’s call him M. Romney or Mitt R. — the question of Mormon differences from historical Christianity has been very much in the air. Not too long ago, for instance, we published an article (part of a broader discussion on the topic) in which Warren Cole Smith explained why he, as an evangelical, could not vote for a Mormon. This became a very controversial piece, eliciting no fewer than three responses in the Washington Post. I have staked out the opposite position: as an evangelical, I’m very comfortable voting for a Mormon. But Warren and I agree on a more fundamentally theologically question: we both believe there are clear and important theological differences between Mormonism and historical Christianity. Those differences worry Warren when he assesses a presidential candidate, while I don’t believe those differences would lead a Mormon to make different policy decisions than a Christian.
