I daresay the Catholic church will survive, as will the Met. It had nothing much to do with the church or musical drama. I haven't heard anything about any of the acting singers who perform at the Met being involved. I would guess that wearing ridiculous clothes and makeup would count as a working meal for them.
It contrasts to something I read a while back about one of the rare, early liturgical orders in one of the early churches that forbade the person conducting the liturgy to interrupt it if a rich person came in as it was going on but required the celebrant to not only greet any destitute or poor people but to give up his seat to one who came in. I should carry a notebook with me so I can write down citations when I read those kinds of things.
The only interesting thing about it was how those secular if not profane celebrities have a shockingly similar view of the Catholic Church as so many of the conservative integralists (Catholic fundamentalists) and so many of the reactionary enemies of Pope Francis, as close to Franciscan simplicity as any pope since the classical period. I heard the organizers were disappointed that the conservative Cardinal Dolan who aided the Gala committee didn't wear his full, red cardinal drag. I'll bet Raymond Burke would have loved to wear the full version including the antiquated, almost never now seen cappa mangna with a really awful saturno hat.
Update: Oops, sorry, I didn't notice the silly decorations on Burke's hat, that would make it an even more antiquated galero, not the more modest saturno style. Please. I'd disqualify him as papabile on that get-up, alone.
