J. R. R. Tolkien’s 1943 claim in “On Fairy-stories” that the Christian Gospel is a fairy story which “has entered History and the primary world” stands over against significant (and widely publicized) elements of Liberal Protestant biblical interpretation of the 19th and 20th centuries, exemplified in Rudolph Bultmann’s 1941 essay, “New Testament and Mythology.” Tolkien’s position, which seems to have influenced C. S. Lewis and Austin Farrer, owes something to G. K. Chesterton but has yet more direct parallels in Thomas Aquinas and Gregory the Great.
