“With a keen eye for detail, a passion for truth, and a desire to probe into the valuable lessons we can learn from the past, Matthew Knell has given the church a wonderful resource in Defenders of the Faith. He pushes us to ask tough questions and to reflect deeply on what it means to be committed to living faithfully for Christ today as we stand in the shadows of those who have gone before us. There is more to this book than history, however. As all good historians do, Matthew challenges our assumptions of today by teaching us to think deeply about yesterday. If we will heed its lessons and follow its trajectory, Defenders of the Faith will help us to remain faithful while helping us avoid the pitfalls of the past that present themselves today in new guises, but with the same dangers as they have always held.”
