Glenn Beck has supplanted the Osmonds as America's most famous Mormon.

Is that a good thing or a bad thing for Mormons? It depends on who you ask, according to the Washington Post's Felicia Sonmez.

Sonmez points out how Beck's comments about President Barack Obama's faith — questioning the president's "version of Christianity" — has concerned some Mormons, whose own Christian faith is sometimes doubted by evangelical Christians.

Beck is "something of a polarizing figure" among Mormons, said Philip Barlow, the Arrington chair of Mormon history and culture at Utah State University. Mormons agree when Beck calls the U.S. Constitution an "inspired document," but are turned off by Beck's description of "social justice" as "a code word for Nazism and fascism."
