Spirituality is a thread that runs through almost all the literary works of English Critic and novelist C. S. Lewis. This is evident in his Chronicles of Narnia (a series of novels written for children), his Space trilogy (a science fiction series), and his last novel Till We Have Faces in which he retells the myth of Cupid and Psyche. This last novel, which is the subject of the present paper, is rich with spiritual and theological allusions. The reader needs to dig deep beneath the literal sense of the pagan myth to discover them. The fact that Christian spirituality is inherent in the literature of Lewis is due to his being one of the most important apologetics in the twentieth century. In addition, his conversion to Christianity after many years of atheism impacted his literary production greatly. Nevertheless, his literature is not directed only to those who can fathom its spiritual and theological senses. He is a novelist in the first place and all his readers can enjoy his writings whether they are able to unmask its spiritual depths or not.
