What happens

Augustine begins the second part of his work, focusing on the origin, history, and destinies of the earthly and heavenly cities. He explains that the two cities were formed by the separation of good and bad angels, and discusses the creation of the world as described in Genesis. He emphasizes that only through the Mediator, Jesus Christ, can one attain knowledge of God, and reflects on the beauty of contraries in the world. The chapter concludes by linking the division of light from darkness in creation to the separation of holy and fallen angels.
