I have serious objections to this particular analysis. It is unfortunate.
Yes, there are many things that Mormons believe that Catholics also believe. However, the differences are wide and broad.
As much as I dislike the Anglicans, my Anglican baptism is accepted by the Catholic church. They would not do so for the Mormons.
That alone should be the first sign that the gulf is broader between Catholicism and Mormonism than between any of the Protestants.
I agree. However, it is true that evangelicalism has become less and less orthodox during the past forty years. I would, however empty many South Baptists who are more dogmatic in their teachings than many of them realize. They cling to an interpretation of Scripture that is closer to that of the chief Reformers than do many of the other mainstream denominations.
