"As always, Nicholas Ayo nourishes the heart and the imagination—not merely the mind. Bookstores are flooded today with works on 'spirituality,' but few of them offer the theological and historical depth that Ayo brings to his work. As I read, I kept encountering passages that made me want to stop and ponder, to find out more, to reread, to linger over an image or phrase." —Nathan D. Mitchell, University of Notre Dame, author of Meeting Mystery: Liturgy, Worship, Sacraments “Christians across many traditions pray and sing the Gloria Patri in our liturgical assemblies. Few, however, realize the theological depth compacted into these few words. Nicholas Ayo's masterful little book opens a treasure house of theological and historical insight contained in this ‘lesser doxology.’ Readers will discover solid scholarship conjoined with mature spiritual reflection in Ayo's pages—a worthy contribution to both Church and academy.” —Don E. Saliers, Wm. R. Cannon Distinguished Professor of Theology and Worship, Emory University “Nicholas Ayo's latest book on prayer reflects both his command of the literature and his profound personal commitment to the patrimony of Catholic spirituality. This work is an exemplary successor to his earlier works on the Lord's Prayer, the Hail Mary, and the Apostle's Creed. Gloria Patri is a work not just to be read but to be savored.” —Lawrence S. Cunningham, John A. O'Brien Professor of Theology, The University of Notre Dame “Anyone who seriously reads this exposition of the Gloria Patri will never again be able to recite this doxology in worship without giving thought to its meaning. The first part of the book is an economically written account of the historical development of the doxology. The second part is an extended meditation on the nature of the triune God, creation, Providence, human existence, and time and eternity.” —Christian Century
