A sterling literary-historian and lay theologian writes:
The excellent lyric ‘All my lufe leif me not’ … belongs to a large class [of] ‘anti-parodies’ (if I may coin a most necessary word): the conversion of popular and secular songs to devout purposes.
-- C.S. Lewis, English Literature in the Sixteenth Century (1944), p. 112
To the man on the Clapham omnibus, this coinage may not seem “most necessary”; you require long schooling to harmonize with that need.
The notion of anti-parody is in line with Lewis’s special use of baptize, whereby a natural (pagan) trait, such as love of nature or appreciation for music, may be said to be “baptized” once such feelings are viewed on a higher plane, from a Christian perspective.
