What is the name of C.S. Lewis’s 1933 book about a pilgrim’s journey toward faith?

The Pilgrim’s Regress is C.S. Lewis’s 1933 book about a pilgrim’s journey toward faith.

Published in 1933, The Pilgrim’s Regress was Lewis’s first prose work after his conversion to Christianity. Its subtitle, An Allegorical Apology for Christianity, Reason and Romanticism, signals the book’s central design: a symbolic journey through competing ideas and spiritual positions.

The protagonist, John, travels through an imagined landscape while seeking the object of his desire. The structure recalls John Bunyan’s The Pilgrim’s Progress, but Lewis’s book responds to modern intellectual and cultural debates as well as Christian themes.

Readers sometimes confuse it with Surprised by Joy, Lewis’s autobiographical account of his intellectual and spiritual development, or The Great Divorce, a later imaginative work about heaven and hell. The Pilgrim’s Regress is distinct as Lewis’s early allegorical defense of Christianity.
