After answering the question of whether Mormons are a cult with a solid "yes and no," we should turn to the next question that's on so many minds, since there are two Mormons in the GOP presidential primary right now: Can I vote for one for President of the United States?
It's true that Mormons are pretty far outside of normal, orthodox Christianity, but their belief system still produces a world view that is in line with that of most evangelical Christians, at least on the most practical matters.
We can expect a Mormon president to be pro-life and pro-family — both in the laws they champion and the judges they appoint. As people who are committed to unpopular and difficult lifestyles, we can expect them to support freedom of religious exercise for all Americans. Beyond that, I think you'll find their chosen party labels tell you more about their views and aims than does their religion.
There are understandable concerns about a Mormon president creating interest in the LDS religion, but I can't believe they'll get such a huge boost from that. People may consider the Mormons out of curiousity, but their decision to stay with them or not will say more about traditional Christians than about the Mormon president.
And how far are we willing to take that concern? If we don't vote for a Mormon because it may cause people to become Mormons, next we may have people in the Church of Christ refusing to vote for Baptists or Calvinists refusing to vote for Arminians. Ridiculous? Yeah. So is voting against a Mormon over this.
There's one truth we need to keep in mind in this whole thing: We're looking for a president, not a pastor.
All of the objections to voting for a Mormon for president should fall away if we keep that truth in view.
One last warning: Even if you don't vote for a Mormon in the primary, it's appearing increasingly likely your choice in the general election will be President Obama or a Mormon. If you decide to opt for a candidate of a minor party — the "true Christian" in the race — you will simply be voting for Obama. That's simply the way our system works.
