C. S. Lewis
After his conversion to theism in 1929, Lewis converted to Christianity in 1931, following a long discussion and late-night walk with his close friends Tolkien and Hugo Dyson. He records making a specific commitment to Christian belief while on his way to the zoo with his brother. He became a member of the Church of England – somewhat to the disappointment of Tolkien, who had hoped that he would join the Catholic Church.
Raymond Wilson Chambers
Chambers was a friend of J.R.R. Tolkien and their careers parallel each other at many points: both were Catholics (Tolkien a Roman and Chambers an Anglo-Catholic), scholars of Old English literature, both experienced the horrors of trench warfare in World War I (Chambers was too old to be an enlisted man, however), and both wrote influentially on "Beowulf" (Chambers' writings were one of the inspirations for Tolkien's ""). Thomas Shippey described Chambers as "a patron and supporter of Tolkien in his early years."
