“Lewis’s conversion was sparked (humanly speaking) by a long nighttime conversation with J. R. R. Tolkien and Hugo Dyson. They were discussing Christianity, metaphor, and myth. In a letter to Arthur Greeves (dated October 18, 1931), Lewis recounted the conversation. It is clear that questions of meaning—that is to say, of imagination—were at the heart of it.
At that point, Lewis’s problem with Christianity was fundamentally imaginative. ‘What has been holding me back . . . has not been so much a difficulty in believing as a difficulty in knowing what the doctrine meant,’ he told Greeves. Tolkien and Dyson showed him that Christian doctrines are not the main thing about Christianity. Instead, doctrines are translations of what God has expressed in ‘a language more adequate: namely the actual incarnation, crucifixion and resurrection’ of Christ.”
