C.S. Lewis's books are as popular as ever. Within Christianity this popularity is, in part, fueled by the American Evangelical admiration for him and the interest in maintaining his role in shaping the minds of the next generation of university students. Academically, Lewis studies have never been healthier and now philosophers and theologians are among those studying Lewis for their own benefit alongside historians and literary scholars. In this context, the paucity of pentecostal engagement with Lewis is noticeable. This article aims to explore the ways in which pentecostal theologians have engaged with C.S. Lewis, and it does so by placing the discussion in the context of public theology. It asks the question as to whether it is appropriate to consider Lewis as a public theologian and, if so, what that means in terms of a pentecostal appraisal of his legacy. C.S.
