We each choose our churches through unscientific, highly personal processes. Some people spend their whole lives worshipping in the same parish—just as their grandparents did and just as their grandchildren will. Others are ecclesiastical butterflies, flitting from congregation to congregation, feeding a little here and a little there. Some people must visit a church for weeks or many months until they decide it’s a good fit. Others know instantly that a church is not for them. A bad experience with one congregation can color a person’s sentiments about an entire denomination forever—or not.
