At my RC church it is standing room only for several of the 8 masses held between Saturday night and Sunday. My (convert) wife’s Byzantine Catholic church is looking for a new building because they are overcrowding the church and getting hit for fire code violations for the number of people coming to Sunday divine liturgy.
If you met some of the people, the families and the priests in those churches you wouldn’t be so vulgar as to suggest that they are not Christians (saved in you parlance). They know exactly what the candles, icons, vestments, vessels, incense and ritual means and are glad to offer it to Christ as a small and humble response to gift He purchased for us at great price.
Well in our area 1/2 the churches have been closed .. maybe they all moved down to you
