The Reason We Don't Count Wikipedia As a Scholarly Source

Thanks to Justin Taylor for this (check it out in its entirety here)

This quote is located in the Wikipedia entry for Jonathan Edwards:
"His sermons such as 'Sinners in the Hands of an Angry God' inspired his parishioners to coin what has now become an American colloquialism: 'Ain’t no sermons like a J. Edwards sermon, ’cause dem J. Edwards sermon don’ stop.'"

This is almost too good to be true.
