We recently interviewed Darryl Hart, adjunct Professor of Church History at Westminster Seminary California, over at Christ the Center. We talked with him about J. Gresham Machen in relation to the modernist controversy, his interaction with colleagues, and his ministry in the church and academy. You can listen to this interview here. Dr. Hart has written several very helpful books. While he has written, or been a contributor for, many helpful books I would recommend those found here, here, here, here, and here. Other Christ the Center programs can be found here.
