This is the sort of theology book Thomas Aquinas envisioned: it brings all that belongs to the Christian faith into a full account that flows ‘according to the subject matter.’ The great tradition comes alive here, in a depth that inspires rather than wearies or confuses. His use of a dialectic of history and ‘message’ is a model for theologians today. A true teacher’s book, and a book that invites students of theology into a rich, ancient, and always regenerating conversation about and with the God of scripture.
