 The faith is embodied in three sacred texts.Believers claim that they date back to the time of Dangun, or even earlier, and this claim, although disputed by scholars, is also accepted by many Koreans who do not belong to Daejongism.The three texts are the "Ch'ónbugong" (The Classic of the Seal of Heaven), a narrative of the origins of the world, the "Samil sin'go" (The Teachings of the Triune God), a theological statement, and the "Ch'amjóngyóng" (The Classic of the Wise One), a manual of ethics.
