This lesson is a review of part I of the course and an introduction to part II. It examines two questions: a) how does God speak to us? b) how does God save us? It reviews the three roles of prophet, priest and king throughout salvation history, shows how Jesus incarnated these roles, and how he passed them on to the Church so that she could communicate Him - the way, the truth and the life - to us through Sacred Scripture, Sacred Tradition and the Church's Magisterium. We also see how God progressively formed His people to be one, holy, catholic and apostolic.
