Fr. Paul Scalia teaches us about what he calls the noonday devil. This is the boredom or indifference toward the goodness of God's gifts and the spiritual life. We can too easily fall into this spiritual malaise. Read and profit from it in the Arlington Herald.
The "noonday devil" is from Psalm 91:6 in the Vulgate. Ralph McInerney wrote a novel by that same name. I have read it more than once and thoroughly enjoyed it. Andrew Greeley reviewed it in the New York Times.
