This article lays out quite well some practical reasons for using organ for Church; for many people today, simply stating that the Church prefers the organ to be used is not enough - they want to know if it is “really practical” for the church to prefer/promote something like the organ. But here is what I think: the Church has to get a couple or a few decades older before she will go more completely back to promoting only true sacred music. What’s more, it will be a number of decades before everyone realizes that the, shall we say, not-so-beautiful, modern churches built after the 1960s need to be renovated/rebuilt to look like a real Church - a truly sacred place. I think that in time, the faithful’s mind will be more in tune with the mind of the Church, and will be more willing to spend money on Church in general, and along with that will include things such as
beautiful churches, and with the proper organ for each building (which in the bigger churches would mean a big, “fancy” organ). I suppose that a particular parish’s diocese might be able to help out a little bit financially, but indeed, it is up to each parish’s parishioners to sacrifice their time, talent, and treasure for the good of their own parish, which contributes to the good of the Church as a whole.
Not to say that no parish today has such people - just that priorities are different today than they have been in the past. I know I am probably gonna get “yelled” at for putting so much emphasis on nice churches (and nice organs), but come on, if people could build awesome churches hundreds and hundreds of years ago, how much more beautiful should we be able to make them today?? I realize some people literally don’t have any money to give, but on the other hand, that’s when giving is the most fruitful - when one doesn’t have any money to give. And yes, I’m just as guilty as anyone out there - I don’t do nearly as well as I should in this area. I’m working on it though.
Anyway. To summarize my point, practical reasons for using the organ in Church are only going to go so far. If organs ever make a comeback in the Catholic Church, it will only be because of 1) a heightened awareness and desire for beauty and 2) a heightened sense of thinking with the mind of the Church, which prefers certain things for the sanctification of its members.
I hope I didn’t babble on too much.
