While its always beautiful, the Catholic Church doesn't have much room to stand on in regards to adorning their churches with lavish spending. Even in my mega poverty area of Louisiana where every other denomination was in a literal shack, the Catholic church had massive art pieces, gold everywhere, and all sorts of other very expensive things to stare at as they passed the donation bowl around.

In this case its more of a traditional and beautiful making it seem less offensive than nu-rich and in your face. And it certainly helps the feeling of being in a house of worship and its sanctity, instead of the Mega Churches feeling like a pop concert.
