Humans are made in the image of God, and authentically coming to be human means to become like him. This work pursues a robust and renewed theology of grace in conversation with the patristic traditions of Irenaeus, the Cappadocian Fathers, and Augustine, the medieval theology of Maximus and Aquinas, and such modern interlocutors as Soren Kierkegaard, Bernard Lonergan, John Milbank, and John Behr. It thereby regrounds our interpretation of Scripture in the wide tradition of the church. By doing so, it argues that Christ's incarnation, crucifixion, and resurrection form the only possible point of reference by which we can understand the universe, as God creates it and works in it to bring us into union with himself.
