One great problem with much art that’s called “Christian” is agenda, which is to say that it’s either didactic, or manipulative, or merely pragmatic—in other words, the artistic purity of the work tends to take a back seat to the artist’s agenda. L’Engle says art that isn’t good is, by definition, not Christian art, while on the other hand art that’s good, true, and beautiful is Christian art, no matter what the artist believes.
