Origen Adamantius was an early Christian scholar, ascetic, and theologian who was born and spent the first half of his career in Alexandria. He was a prolific writer who wrote several treatises on theology, textual criticism, biblical exegesis and hermeneutics, homiletics, and spirituality. In the Homilies on Joshua, Origen unfolds the story of the Christian life from baptism to resurrection and the celestial rewards, basing his exposition on the death of Moses, the crossing of the Jordan, and the conquest of Palestine.
