Compare any ten random Catholic parish churches to any ten random evangelical megachurches on that "nice comfortable attractive" metric and get back to us.
My parish church was built in 1847. It's not falling down yet, but we've had to cut back on expenses so that some of the structural issues could be addressed.
We don't have an auditorium with a $100,000 professional sound system and a coffee bar nicer than most Starbucks ... but I know a Baptist church that has both those things.
Most Catholic facilities are not like St Peters. Many of them are in fact pretty shabby, because Catholics don't put much money in the collection plate compared to some other groups.
Yes the protestants are not monolithic. For every Starbucks church youll find a storefront or a congregation meeting in a school.
In re the RC church I refer mostly to Vatican City, Rome in general, the whole priceless art collection thing. Not a good look in my opinion.
I am all for private property and investments and such. But the pope is declaring socialism and green new deal and etc, inconsistent.
