"My own debt to [Unspoken Sermons] is almost as great as one man can owe to another." With these words, C.S. Lewis acknowledged the role the George MacDonald's spiritual writings (as well as his novels) played in his own faith journey and theology. In this week's episode Drs. Crystal and David C. Downing, along with Producer Aaron Hill, explore a volume of MacDonald quotes collected and edited by C.S. Lewis called George MacDonald: An Anthology. Explore literary and theological parallels between Lewis and MacDonald, the theological themes that marked MacDonalds life and spiritual writings, and the ongoing relevance of MacDonald's writings for Christians living in the 21st century.
