Actually, in both Catholic and Protestant churches alike, form has given way to function. Land prices and building costs often dictate building space - in the name of good stewarship. Most spaces have to serve more than one function, which can lead to both creativity and a sense of drab.
I grew up in a very gothic church, pipe organ, traditional architecture. It was remodeled in the 90’s for over a million dollars. To build a new structure, including a comparable pipe organ, would cost nearly 8 million dollars. There’s no way that most churches or parishes could afford such a structure.
Staff salaries and benefits, ministry programming, clerical/office costs, insurance premiums, utility costs - all realities. The church/parish I now serve cost a little under $150,000 to build in the 1950’s. It would now cost $4,100,000 to build something comparable. I don’t know how we’d pull it off.
Early Christians met in homes.
