Chesterton's Commentary on Commentaries

I usually enjoy reading snarky comments about biblical commentaries. I ran across a good one by Chesterton, commenting on commentors of the Book of Revelation:

Though St John the Evangelist saw many strange monsters in his vision he saw no creature so wild as one of his own commentators.

—G. K. Chesterton, Orthodoxy, 13. (GBks, 1901 ed, 19)
