Here goes the quotation (my emphasis):
Teabing chuckled. "The ivory towers of Harvard have made you soft, Robert. Yes, the clergy in Rome are blessed with potent faith, and because of this, their beliefs can weather any storm, including documents that contradict everything they hold dear. But what about the rest of the world? What about those who are not blessed with absolute certainty? What about those who look at the cruelty in the world and say, where is God today? Those who look at Church scandals and ask, who are these men who claim to speak the truth about Christ and yet lie to cover up the sexual abuse of children by their own priests?" Teabing paused. "What happens to those people, Robert, if persuasive scientific evidence comes out that the Church's version of the Christ story is inaccurate, and that the greatest story ever told is, in fact, the greatest story ever sold"

Is this sentence to be taken literally? Or does it mean something else?
