While traveling, Applewhite and Nettles pondered the life of St. Francis of Assisi and read works by authors including Helena Blavatsky, R. D. Laing, and Richard Bach. They kept a King James Version of the Bible with them and studied several passages from the New Testament, focusing on teachings about Christology, asceticism, and eschatology. Applewhite also read science fiction, including works by Robert A. Heinlein and Arthur C. Clarke. By June 1974, Applewhite and Nettles' beliefs had solidified into a basic outline. They concluded that they had been chosen to fulfill biblical prophecies, and that they had been given higher-level minds than other people. They wrote a pamphlet that described Jesus' reincarnation as a Texan, a thinly-veiled reference to Applewhite. Furthermore, they concluded that they were the two witnesses described in the Book of Revelation and occasionally visited churches or other spiritual groups to speak of their identities, often referring to themselves as "The Two", or "The UFO Two". The pair believed that they would be killed and then restored to life and, in view of others, transported onto a spaceship. This event, which they referred to as "the Demonstration", was to prove their claims. To their dismay, these ideas were poorly received.
