"This book is masterfully written, and it is a must-read for anyone interested in Christian dogmatics. Case offers a highly worthwhile retrieval of Bonaventure and his early followers, constructively criticizing various positions taken by Aquinas." — Matthew Levering, author of Aquinas's Eschatological Ethics and the Virtue of Temperance"Doubting Thomas brings to light the philosophical arguments between Bonaventure and Aquinas across a range of issues. This well-written and well-informed book expertly illuminates what was at stake in their disagreements. You will not see the thirteenth century the same way after reading this book." — Christopher Cullen, author of Bonaventure: Great Medieval Thinkers"It is with good reason that St. Thomas Aquinas has been named the Common Doctor of the Church. However, as Brendan Case argues in his insightful and provocative book, it is for equally good reasons that St. Thomas has not been named the only doctor of the Catholic Church. Theologians of all stripes will benefit, therefore, from Case's engaging and detailed display of the numerous theological gifts on offer from St. Bonaventure, Blessed John Duns Scotus, and the wider Franciscan tradition." — T. Adam Van Wart, author of Neither Nature nor Grace
