"John Gerstner was a dynamo. His energy was mainly evident to those who heard him speak, but Jeffrey McDonald's careful biography comes just as close to capturing the vigor that informed the Pittsburgh professor's voice, heart, and mind. This book is a must read for anyone interested in Calvinistic evangelicalism after World War II."
--D. G. Hart, Distinguished Associate Professor of History, Hillsdale College, Michigan

"This well-researched book illuminates the career of a scholar, churchman, and memorable teacher who left a major mark on American Christian life."
--Mark Noll, Author of America's God: From Jonathan Edwards to Abraham Lincoln

"I commend his work to anyone who seeks a better grasp of orthodox reformed theology in mainline Presbyterian denominations in the twentieth century."
--Don MacLeod, Research Professor of Church History, Tyndale Theological Seminary, Toronto

"Jeff McDonald demonstrates that his subject, in company with a cohort of fellow United Presbyterians in western Pennsylvania, exercised an influence on American evangelicalism out of all proportion to their numbers."
-- Kenneth J. Stewart, Professor of Theological Studies, Covenant College, Georgia

"A well-researched and engaging biography that portrays the successes, failures, and enduring legacy of this key player in American Reformed evangelicalism."

--Mark Noll, Author of America's God: From Jonathan Edwards to Abraham Lincoln

His energy was mainly evident to those who heard him speak and preach, but Jeffrey McDonald's careful biography of Gerstner comes just as close to capturing the vigor that informed the Pittsburgh professor's voice, heart, and mind. This book is a must-read for anyone interested in Calvinistic evangelicalism after World War II.

"To date, studies of the post-World War II theological resurgence of American evangelicalism have focused on greater Boston, greater Chicago, and greater Los Angeles.
