This spring a certain Christian layperson has been criticized for not exiting his local church when he disagreed with something his pastor preached.
The experts on the subject have been, as far as I can tell, media personnel who never go to church, do not know what sermons are for, and have not experienced lively congregational participation; people who value fidelity very little and church hopping and sermon shopping very highly; those who have political stakes in their judgment; and people who pay no attention to the contexts of messages.
