Beck then began a "spiritual quest" in which he "sought out answers in churches and bookstores". As he later recounted in his books and stage performances, Beck's first attempt at self-education involved reading the work of six wide-ranging authors, constituting what Beck jokingly calls "the library of a serial killer": Alan Dershowitz, Pope John Paul II, Adolf Hitler, Billy Graham, Carl Sagan, and Friedrich Nietzsche. During this time, Beck's Mormon friend and former radio partner Pat Gray argued in favor of the "comprehensive worldview" offered by The Church of Jesus Christ of Latter-day Saints, an offer that Beck rejected until a few years later (Later, after Beck's moving to the New York City area, he had a consultation with Graham, which Beck said touched him strongly).
