"Matthew Levering has acquired a well-earned reputation for being amazingly prolific without ceasing to be substantive and profound. In this work he has done it again! No one interested in the doctrine of the Holy Spirit--and especially in the seminal contributions of Augustine and Aquinas--can afford to ignore this rich and stimulating book."
--George Hunsinger, Hazel Thompson McCord Professor of Systematic Theology, Princeton Theological Seminary

"This is surely the most substantive theological treatise on the Holy Spirit to appear since Yves Congar's great work on the subject over a generation ago. Like Cardinal Congar, Matthew Levering knows that 'the river of life' flows in both the West and the East, and more than Congar, he brings the immense riches of the Western Catholic tradition's teaching on the person and work of the Spirit to bear on the manifold problems of the present."
--Bruce D. Marshall, Lehman Professor of Christian Doctrine, Perkins School of Theology, Southern Methodist University

"In this landmark achievement, Matthew Levering presents his theology of the Holy Spirit. The result is a deeply informed, robust, Catholic articulation of the person and work of the Holy Spirit, whose proper names are Love and Gift. It is rare to encounter such a remarkable range of biblical as well as doctrinal theologians, presented by way of irenic yet vigorous discussion. As readers of Levering would expect, Thomas Aquinas takes the position as the theologian of the Holy Spirit. This book is vintage Levering!"
--Hans Boersma, J. I. Packer Professor of Theology, Regent College

"An exemplary work of ecumenical theology. Levering guides the reader through the most central and subtle questions of the theology of the Holy Spirit. He engages systematically with scriptural, patristic, medieval, and modern topics and relates the whole study coherently to the mystery of the Church. A splendid achievement of wonderful intellectual breadth and profoundly Catholic verve."
