From Berean Research:
Glenn Beck loves playing the role of America’s spiritual leader. However, we must remember that Mr. Beck is a member in good standing of the Church of Jesus Christ of Latter-Day Saints aka Mormonism. Mormonism is a pseudo-Christian cult. Glenn Beck makes no bones about the fact that he embraces LDS theology, which is decidedly unbiblical. So is it really his place to advise evangelical Christians on spiritual matters, especially when it comes to fasting and prayer?
No.
