There is a church in Las Vegas in which only 14 of their 25 small groups are listed in the church service directory. Why? Because the other 11 don’t have a start/stop time.
Instead they function as a family, 2’s and 3’s getting together several times a week, most of the group getting together once or twice a week for whatever, celebrating birthdays and anniversaries, just generally being a family, being the people of God. Not that they are totally insular, plenty of new people come; the friends of the people that are already a part of it, in fact at any given time, as many as 50% of the people might not identify themselves as Christians.
Got any thoughts, what might the pros and cons be?
