This book presents the chief insights concerning the mystery of atonement in the works of four theological guides: John Paul II, Joseph Ratzinger/Benedict XVI, Hans Urs von Balthasar, and Norbert Hoffmann.The author argues for the central importance and perennial value of a theology of atonement, even as she explains the modern aversion to it. The book's central aim is to deepen our understanding of the biblical claim that God shows himself to be love precisely by sending his Son as atonement. "In this is love: not that we loved God, but that he loved us and sent his Son as expiation for our sins" (1 Jn 4:10).The book develops a compelling vision of atonement as a process that originates from and is engendered by God's own power to love. This vision not only takes account of the gravity of sin and its consequences, but also provides a clear illumination of the wholly gratuitous, radically forgiving, passionate and powerful nature of God's redeeming love for mankind. Distinct from the majority of theological accounts of atonement, which focus almost exclusively on the role of Christ, this book highlights the role of God the Father in the atoning mission of the Son.
