Castaldo

Rev. Chris Castaldo
Director, Ministry of Gospel Renewal

Chris serves as the director of the Ministry of Gospel Renewal for the Billy Graham Center at Wheaton College. Originally from Long Island, New York, Chris was raised Roman Catholic and for years worked full-time in the Catholic Church alongside bishops and priests.

His ministry focuses on equipping evangelicals with the requisite knowledge and tools for constructive witness among the 99 million partially-evangelized persons in America—those who possess a nominal connection to the church, but for whom the gospel is missing. His approach seeks to convey the delicate balance of grace and truth—genuine love for people with gospel conviction. Chris is author of Holy Ground: Walking with Jesus as a Former Catholic (Zondervan, 2009). He is currently pursuing a PhD which examines the doctrine of justification in the writing of Peter Martyr Vermigli and John Henry Newman. Chris, his wife, Angela, and their four children live near Chicago.
