Honestly, I knew Fuller trends to a more progressive view of theology and culture than I could align myself with.
This article written by their president shows that progression.
"Those of us who have made the effort to engage Mormons in friendly and sustained give-and-take conversations have come to see them as good citizens whose life of faith often exhibits qualities that are worthy of the Christian label, even as we continue to engage in friendly arguments with them about crucial theological issues."
1. There are plenty of Atheists, "whose life of faith often exhibits qualities that are worthy of the Christian label..." Thankfully, they won't be taking that label, no matter how broad and culturally savvy Mouw wants to make it. They're not taking the label because they don't follow Christ. Neither do Mormons...at least not the same Christ the Bible teaches.
2. One of the biggest problems with this article is that it makes Christ somehow trans-belief, trans-religion figure that can be found in equal amounts of truth in religions other than Orthodox Christianity. For example: Matt 5:17-19. If what Jesus is saying is true of the Bible, then what the Mormons believe about Joseph Smith, their continuing revelation of their elders, and the Book of Mormon being supreme above the Bible isn't compatible with Jesus says about the Bible and what the Bible says about Jesus.
Mormons aren't Christians.
And, it's ok.
It's cheap to score political points at the expense of ones religious beliefs.
And,
It's theologically irresponsible to try and syncretize Christianity and Mormonism for the sake of Evangelicalism.
It only ends up as a disservice to Evangelicalism.
