Christian faith

Christianity in C. S. Lewis’s account is a belief lost and recovered by stages, not a continuous inheritance or a single sudden conversion. His retrospective narrative distinguishes early Christian belief, apostasy, surrender to God as a theist, and eventual acceptance of the Incarnation. Each stage changes what he thinks religion can mean: first a doctrine made real by worship and teaching, then one faith among many that he rejects, and finally the fulfillment he recognizes in the person of Jesus Christ. At the end of that movement, Joy remains, but its significance has shifted from experience to pointer.

Early Belief and Apostasy

At Oldie’s school, the church services held twice every Sunday first made Lewis an effective believer. The worship was high Anglo-Catholic: candles, incense, vestments, and hymns sung on the congregation’s knees. Consciously, he resisted these practices as unfamiliar signs of the English atmosphere he disliked. What mattered more was hearing Christian doctrines taught by men who plainly believed them. Since he had not been skeptical, the teaching gave life to beliefs he would already have said he held.

This beginning involved fear, especially fear for his soul on blazing, moonlit nights in a curtainless dormitory. Lewis later judged that fear not excessive but wholesome, and associated the prominence of Hell in his books with the Anglo-Catholicism of the church at Belsen rather than with the supposed Puritanism of his Ulster childhood. The practical consequences were prayer, Bible reading, and attempts to obey his conscience. Religious discussion among the boys, as he remembered it, could be grave and healthy without becoming hysterical or shamefaced. This was genuine religious practice, but it did not prevent a later departure from faith.

At a later stage, prayer itself became a burden. Lewis demanded a vivid imaginative and emotional “realization” to accompany every clause of his prayers, trying by sheer will to produce an experience that could not be willed into being. The nightly effort became uncertain and exhausting; cold oilcloth, chiming quarters, and the night slipping away made bedtime an ordeal. He later recognized this self-imposed false duty as an unconscious motive for wanting to leave Christianity. Classical reading supplied a more conscious challenge: in the treatment of religious ideas in Virgil, teachers and editors seemed to regard pagan religion as nonsense while exempting Christianity as uniquely true, without explaining the relation between them. Lewis wondered why his own religion should be treated as a different kind of thing and found himself unwilling to preserve the distinction.

His pessimism also worked against belief. He judged the universe broadly regrettable, and his atheistical “Argument from Undesign” sat alongside occult interests without any logical connection between them; they shared only their opposition to Christianity. Gradually, with fluctuations he could no longer reconstruct, he became an apostate. He describes the result as relief rather than loss. The memoir therefore refuses to make childhood belief an inevitable prelude to conversion: religious practice, intellectual doubt, pessimism, and occult fascination pull in different directions before faith is abandoned.

From Materialism to Theism

During the Bookham period, Lewis’s materialism was troubled by writers who took a spiritual world seriously. Yeats’s prose showed him that its author believed in beings beyond ordinary material reality and in the possibility of contact with them. Because Lewis had treated scientific findings as authoritative without being a scientist himself, Yeats presented a competing authority he felt obliged to consider. Reading Maeterlinck brought him into contact with Spiritualism, Theosophy, and Pantheism. Lewis did not assent categorically, but the possibility of “something else” unsettled his materialism and revived the occult interests associated with the Matron at Chartres.

A more sustained intellectual challenge came through his friend Barfield’s conversion to Anthroposophy. Their long dispute was not a quarrel, but an almost continual argument by letter and face to face, and Lewis later called it one of the turning points of his life. Barfield undermined Lewis’s chronological snobbery: the assumption that what is out of date is thereby discredited. A belief’s disappearance, Lewis came to see, does not show that it was refuted; the present age, too, has characteristic illusions, especially in assumptions so widely shared that they seem to need no defense.

Barfield also exposed a problem in Lewis’s realism. Lewis had treated the sensory universe as ultimate reality while continuing to regard logic, moral judgment, and aesthetic value as more than subjective preferences. If thought were only a subjective event, those claims could not stand as he had made them. A thoroughly materialist alternative, including a behaviorist account of logic, ethics, and aesthetics, seemed to Lewis literally unbelievable. He therefore had to give up realism and admit that mind could not be merely a late-arriving by-product of matter: ultimately, the universe was mental, and logic participated in a cosmic Logos. The shift did not itself make him Christian, but it weakened the materialist framework that had supported unbelief.

Surrender to God

In 1929, while alone in his room at Magdalen night after night, Lewis felt the approach of the God he had wanted not to meet. His earlier desire not to be interfered with had shaped even his attempt to live by philosophy: he had kept reservations against any demand that might bring intolerable suffering. Now, he recalled, the demand was no longer a negotiated limit but total surrender. In Trinity Term he gave in, admitted that God was God, knelt, and prayed. He remembered himself as perhaps the most dejected and reluctant convert in England.

This conversion was to theism alone, not yet to Christianity. Lewis knew nothing of the Incarnation, and the God he acknowledged was, as he put it, sheerly nonhuman. Nor did he then believe in a future life. He was allowed, he later regarded it as a mercy, to know God and attempt obedience for months, perhaps a year, without making immortality the question on which his religion depended. The separation matters: intellectual and religious surrender to God had occurred, but Christian doctrine and institutional belonging had not yet followed.

The Incarnation and the Maturing of Religion

After acknowledging God, Lewis reconsidered the apparent multitude of religions. His question was no longer which religion was simply true among a thousand false ones, but where religion had reached maturity and whether the hints of paganism had been fulfilled. With encouragement from Barfield to regard pagan myth more respectfully, and with the thought prompted by a hard-boiled atheist’s observation about the Dying God, Lewis treated pagan worship as neither mere nonsense nor a final destination. He considered Hinduism and Christianity the two possible answers. Hinduism seemed to him to leave philosophy alongside pagan practices he regarded as unpurged; Christianity also made a historical claim that he could not dismiss as myth.

The Gospels struck him as unlike either ordinary myth or ordinary history. Their plain account of Jesus, set among a people who seemed blind to the surrounding pagan mythic wealth, described something that resembled the great myths while remaining historically particular. Lewis came to see the story not as one religion or philosophy among others, but as their summation: myth made fact, the Word made flesh, God made Man. That recognition was not an automatic consequence of his earlier theism. As he approached it, he felt resistance because each step—from the Absolute to Spirit, from Spirit to God, and now to the Incarnation—made the divine more concrete and more difficult to evade.

He located the final change on a drive to Whipsnade. When the journey began, he did not believe that Jesus Christ was the Son of God; when he arrived at the zoo, he did. He did not describe the journey as a deliberate argument or as an emotional climax. The realization was more like becoming aware, after a long sleep, that one was awake. This account presents Christian belief as a further, more particular commitment than theism: not simply an assent to God, but acceptance of God’s presence in Christ.

Christianity, Practice, and Joy

Lewis’s churchgoing after his theistic conversion was provisional and symbolic, not a sign that he had already become Christian. He disliked the collective bustle of church, its crowds, bells, notices, umbrellas, and organization; hymns and the organ displeased him, and he felt spiritually awkward in rites. His chief companion during this stage was Dom Bede Griffiths, with whom he maintained extensive correspondence. Both believed in God and were willing to hear about Him from pagan or Christian sources. Lewis’s continuing questions were intellectual as well as devotional: he wanted to understand where the religious traditions converged and what distinguished their maturity.

Christianity also changed the place of Joy in his account. Lewis did not say that the old bittersweet experience disappeared after conversion; he believed it still came as often and sharply as before. What changed was his estimate of its importance. As a state of his own mind, Joy had never been the ultimate object. Its value lay in directing him toward something beyond himself. Before the road was known, the signpost dominated attention; once the road was found, the signposts could be welcomed without becoming the destination. In this retrospective structure, Christianity does not erase Lewis’s earlier experiences of Joy. It gives them a new interpretation: they point beyond the experience toward the reality he has come to believe in.
