I heard two very pithy remarks recently:
"The mass should be something that prevents us from being children of our age."
(said in reference especially to music, art, and architecture.)
"The progressivists have dumbed down our theology and catechesis, but when a simple lay man tries to make an analogy - such as one to hunting and waiting at Lent - they go crazy on the left. What gives?"
(said in reference to this article.)
