Grace And Necessity: Reflections on Art And Love is an expansion of a series of lectures Rowan Williams gave in 2005. In the first chapter, Williams expounds the aesthetic philosophy of Jacques Maritain. Consider these quotes:

Art as propaganda, its workings determined by the purpose of of persuading those who see and hear of a message that can be separated from the actual work, is nonsense.

Bad men make good things; but good men also make bad things, works that are intrinsically dishonest and empty, because they do not keep their eyes on the good of the work – even when they have a sound conception of what is good for the sort of beings we are.

Given my profession, my first thought was what Maritain would think of Christian music. Is it art? Should it be art? Does its proselytizing nature undermine its potential value?
