This chapter deals with a general definition of reason', and with the reasonableness of three major Christian beliefs. Christianity belongs in the Abrahamic set of religious traditions, and as such it shares the Abrahamic view that the prophets of ancient Israel and Judah were genuine recipients of divine revelation. The books of the Hebrew Bible consist of a number of writings from different periods of history, expressing a number of different points of view, and recording how the writers or editors saw the revealing activity of God in ancient Jewish history. The central claim of the Incarnation is that God reveals the divine presence, nature, and purpose in the life and teachings of Jesus. The purpose is claimed to be that human and divine should be so intertwined that they actually become one. The Christian mystery of the Atonement is not the contradictory statement that a God who cannot die suffers death.
