My mother-in-law is a die-hard Catholic and has been raging for the past three months because she can't go to church, and I just don't understand why she can't just watch the live-stream that the priest is doing. But for her, there's something about physically accepting communion. (I'm not Catholic, so I don't really get it, but I've been sternly informed that I should just not talk about that with them lol). I've often thought of churches as a poor man's country club more than as a house of God, and so yeah, I'm with you! I don't see why this can't just go remote like most everything else. I do wonder how the long-term landscape will change due to COVID...
