The Middle East is really tough duty to pull for your missionary work.
As an evangelical Christian who has some huge issues with Mormonism, I think this guy really misses the mark badly. One would not imagine Islamic nations coming to the aid, unless in just a very token way, to any no Islamic nation or people. I could see Mormons doing it.
I think it would also be fair to say that when Mormons and Christians (Mormons do believe all other Churches are an abomination, so it is fair to make a distinction) have a common social goal, it does not in any way imply they are theological in agreement on even the most basic tenets of faith.
As I said, this guy is way off base; and even I would not hint or suggest that Mormons have anything in common with Moslems.
I have read some of Daniel Peterson's articles and been kind of confused. Thanks for clearing up some of where he was coming from.
