At church these days we have to 'check-in' before we attend. In fact, we have to check-in everywhere: restaurants, cafes, bars, nightclubs, ordinary clubs, probably even the Boy Scouts.
Our church includes home groups in the check-in routine.
Every church does it!
I deeply resent it and I'm not going to 'check-in' when the governments obsessive requirement is lifted (all this for a disease with a case fataility rate of 0.01, much less than that once we move away from the over 70 group.
But, I don't want anyone 'tracking' my spritual life, let alone the government. It has nothing to do with government and everything to do with my privacy.
Once data is obtained, it is there forever. Who knows where it will go to?
But it's not only about government. I won't check-in to ordinary church service. I'm happy for ticketed events like training seminars, grouped dinners (like 'men's', 'womens', etc.), and other specially provided functions. But for prayer, general congregational gatherings, not on your nelly. It betrays the fluidity, privacy and organic nature of the christian family.
