George Barna is now saying that in the US "9% of adults attend a house church during a typical week" -- up from 1% a year ago.
I'm generally open to the house church movement and try to follow what's happening -- a great opportunity to make some connections. But 9%? House church life requires a high level of commitment. You can't be a casual participant in a house church and yet American church life if anything is moving toward more casual participation -- across the board.
Possibilities: 1) I'm totally blind. 2) The survey questions were poorly worded. 3) Most people tend to lie when they report church participation. 4) All of the above.
