What a bunch of guff.  I'm 65 and I remember the "old days'" and I remember that constant appeals for money for the upkeep, etc. My currant parish was built in 1968 and it's as  plain as plain as plain can be and our community likes it that way.  As for the Millenials, they aren't dry behind the ears yet, as my sainted dad would say. WHAT do THEY know ? THEY think PBR is good beer.  The way we worship now is a lot closer to the way the way the earliest Christian worshipped than those  overbuilt  edifices. Ad Orientem strike me as much MORE resembing worshipping the golden calf than our currant way.
