Have you heard of a little theological term, theosis? This is an important term, beloved and taught most explicitly in Eastern Orthodox Christianity, but is at the heart of Christian hope. And, many Christians believe, at the heart of Christian experience. It's a term that grabbed my attention many years ago because to my little ol' Pentecostal heart, it captured the dynamism of life in Christ I'd been told I should pursue growing up and homed it within the life of the Church and most ancient root systems of the Christian faith. If you've not heard this word, I'll leave you with that teaser for now.

Many of us have had these moments of finding the vocabulary of the heart, or of some experience or desire we couldn't quite name, suddenly appear before us in the writings of the saints. Then when I started reading C.S. Lewis, I found a translator and a teacher of many of these concepts, and an imagination that helped me put them on a theological map -- maps that often looked like Narnia or the planet Venus.

Though Lewis doesn't use the word "theosis" in his writings, I found my understanding of this core Christian hope expand under his teaching. And I wondered how much interest in or exposure to Eastern Christianity Lewis had in his life. Who were his teachers? What do we learn through what he was learning about love's redeeming work?

So, on to theosis in the life, works, and relationships of CS Lewis. What do we find there? I had a couple of conversation partners and guides who were up to the task, and we unearthed a few delightful surprises together.

Drs. Crystal and David Downing are co-directors of the Marion E. Wade Center at Wheaton College, Illinois, which promotes the work of C.S. Lewis, J.R.R. Tolkein, Dorothy Sayers, Charles Williams, and other key British Christian authors, and helps develop new writers and scholars of faith and imagination.

Crystal formerly served as Distinguished Professor of English and Film Studies at Messiah College, and is the author of several books on Dorothy Sayers, postmodernism, and film. Her most recent book, Subversive: Christ, Culture, and the Shocking Dorothy L Sayers, won a starred review by Publisher's Weekly and was Publisher's Weekly's pick of the week.

David Downing has written several scholarly books on C.S. Lewis and provided a critical introduction and explanatory notes to the new edition of C.S. Lewis's The Pilgrim's Regress. He also serves as a consulting reader of Lewis and editorial consultant for a number of academic publishers.

Now enter the wardrobe, hop on the bus, and snuggle into your space capsule. Or hold tight to your copy of St. John Climacus. And enjoy the conversation.
