Welcome to our newest series.
Owen Barfield: The First & Last Inkling.
This episode provides a brief introduction to Barfield's life and work. In the weeks to come, we will host thoughtful conversations with 10 different guests, each providing a unique perspective on Barfield's philosophy, spirituality, and the imagination.
We will discuss the influence of Rudolf Steiner on Barfield, the interaction between C.S. Lewis and Barfield (dubbed "The Great War"), and Barfield's understanding of the evolution of consciousness. No person is complete without the full integration of reason and imagination, and Barfield provides ample evidence for this reality, as well as meaningful guidance for humanity's participation in a transcendent future.

Welcome to Episode 8 of 9 in our series on C.S. Lewis's novel The Great Divorce.
Today's conversation features Joel Wentz. In this episode, Joel and I discuss the miracle of the redemption of disordered desires, why The Great Divorce is a great book for a neighborhood book club, the proper terror of A Wrinkle in Time, and possible reasons for the manner in which Lewis portrayed George MacDonald's theology of the ultimate redemption of all people (Christian universalism).
Joel and his wife Jill live with their two children in Portland, Maine. Joel has been in vocational ministry for 12 years. Joel spent 8 years as a campus minister with InterVarsity Christian Fellowship, and he has served for the past 4 years in his current role as teaching pastor at Missio Dei Church. https://www.mdchurch.org

Welcome to Episode 5 in our 9-part series on C.S. Lewis's The Great Divorce. Thank you for joining us as we explore the ideas presented by Lewis in this fantastic tale, a dream vision, written in response to William Blake's The Marriage of Heaven and Hell.
Today's conversation features Karen Scheffler, who is originally from Philadelphia, Pennsylvania. Half a lifetime ago, she moved to Vermont where she and her husband raised two boys. Karen has been a teacher, an artist, a wildflower, and a business owner. She's the person who stands in the back of the room, taking it all in.
In her words, Karen is "an insignificant human intensely interested in becoming that shining light about which she's heard rumors - less and less terrified about what it means, mainly because of all the stars she's been meeting along the way.
Karen and I discuss the Secret Garden and the Sacred Heart, the horrors of Lewis's portrayal of the great and terrible afterlife, and the power of un-masking ourselves and becoming who God made us to be.
