Let me save everybody a lot of time. If by "Christian" you mean "believes in the version of God and Christ taught in the Nicene Creed," then absolutely not. Right from the start, the founding prophet of the Mormon Church, Joseph Smith, rejected that view of God as a fantasy.
Of course, by our definition of "Christian theology," we're the only Christians. That's why we send out missionaries to preach to Baptists and Methodists right along with the heathens.
And let's remember that Catholics have historically had a pretty low opinion of the doctrines of Lutherans and Quakers and Presbyterians -- and vice versa.
But in America, we all agree to get along. In fact, it says it right there in Article 6 of the Constitution: "No religious test shall ever be required as a qualification to any office or public trust under the United States."
We've had plenty of Presidents who weren't Christians, most prominently Thomas Jefferson. But most of them hadn't served as missionaries for their atheistic or deistic beliefs, either.
So let's pretend that it matters. Theologically, Mormons are way outside the mainstream of Christianity.
But how do Mormons actually live?
Despite the efforts of our opponents to paint us as a "cult," we don't live in communes in Guyana. We hold regular jobs. Most Mormon kids go to regular schools.
We wear regular clothes. (OK, maybe a little more modest than most, but that's a good thing, isn't it?)
We don't smoke or drink or do drugs -- but that makes us safer drivers and more reliable employees and better company in small closed rooms, doesn't it?
Let's forget about doctrinal religion and look at practical religion. Mormons are people who take their worship of God seriously. We really try to live by the commandments of God, as we understand them -- and they're not a bad list of commandments.
In fact, they sound kind of like what most American Christians would aspire to. Get married, be faithful to your spouse, have babies and raise them right. Don't let your life be taken over by drugs or alcohol. Hold down a job and support a family. Go to Church. Contribute to charity. Help your neighbor when he needs a hand. Be honest in your business dealings.
If you think we're not Christians, fine. But we make decent neighbors and co-workers, most of the time. And since we all agree there should be no religious test to be President, then what difference can our doctrines possibly make?
In fact, when you come right down to it, can you think of any significant point on which Mormons would disagree with an ordinary conservative Christian's view of what a President ought to do?
We may have different opinions about the nature of God, but we still pray to the God of the New Testament and recognize Jesus Christ as the Savior of the world, and try to obey his commandments, like any other practical Christians.
We Mormons treat President Bush's religious faith with respect and regard him as a Christian even though we think his theology is wrong; I think Methodists and Baptists and Catholics are mature and generous enough to treat a Mormon President the same way.
