Celtic mythology appealed greatly to Lewis, and his natal attachment to Northern Ireland never left him. The harder he tried to pretend God did not exist, the more he came into contact with Christian influences, beginning with the fictional writings of George MacDonald, and, after 1926, the friendship of Tolkien, his own brother Warnie, and several other colleagues, as well as the writings and influence of G.K. Chesterton. He claimed that his full conversion to Christianity took place in 1931 and he admitted to entering Christ’s kingdom kicking and screaming. He joined the Church of England, although he himself was highly ecumenical and his admirers come from all corners of the Christian Church. Lewis readily admitted he was no theologian though, and merely suffused his novels with a “culturally Christian” worldview, often veiled in metaphor and anthropomorphizing.
