I’ve been to Mass at many churches that look like fire halls on the outside and school cafeterias on the inside.
I have too, but I do believe that it only has to do with money. The Catholic Church cannot build those huge Cathedrals like buildings anymore because of the costs involved.
Not true in my diocese. St Gregory the Great Parish in VA Beach is very wealthy. They chose to build a very expensive, very large, bland and beige palace.
