Irenaeus (c. 130-200) was a church father who wrote in Greek against the Gnostic heresies of the day. Irenaeus is known for his argument that Christ came to actualize all those perfections that God had intended humans to have but that were lost through the sin of Adam and Eve. He is also known for having inspired a “soul-making” theodicy, which justifies suffering as part of the process whereby humans hecome all they can be.1
