Beck announced on Monday that he'll be holding a "Restoring Courage" rally in Israel this August, so people can "stand together and show the world what living a life of faith and honor really means."
Keller, founder of the site Liveprayer.com (which calls itself "the first global prayer meeting"), said in a statement: "The Bible says that we are not to be bound together with unbelievers. It asks what fellowship the light has with the darkness?"
"I have challenged Beck for years to tell the truth about what his Mormon cult believes," Keller continued. "He doesn't have the guts to talk to me on air since his 'business' depends on making Biblically illiterate Christians think he is a Christian also. Beck and those in his cult can believe whatever they want. Sadly people who are hurting and spiritually void, will easily fall into the lies of his cult and lost for all eternity. All I have ever asked is that Beck and members of his cult be honest and truthful about what they believe."
The statement also proudly describes Keller as follows:
Keller, an outspoken Christian evangelist who has for decades publicly taken on the Mormon cult, specifically Presidential candidate former Mass. Gov. Mitt Romney and media giant Beck, takes the evangelical position that Mormon doctrine is 100% inconsistent with Biblical Christianity and that a Mormon is no more a Christian than a Muslim is.
Keller once called Islam a "1,400-year-old lie" and "a wonderful religion... for pedophiles" and started the "9-11 Christian Center at Ground Zero," in response to the Park51 Islamic Center. He explained at the time: "It's not designed to be a place where we preach against Islam, although we will preach against Islam and Mormonism and any other false religion."
He also produced the "birthermercial," which asked viewers to buy $30 "got a birth certificate?" bumper stickers.
