The Winston-Salem Journal has the news:
Judge James A. Beaty Jr. of U.S. District Court ordered the county to stop having prayers under its current policy, which allows clergy to pray in any manner before board meetings on a first-come, first-served basis. Since the policy was set in March 2007 most prayers have made reference to Jesus.
Beaty said that the effect of the policy has been to "advance a specific faith or belief."
He said that the county has the option of having no prayer before meetings or requiring that prayers be nonsectarian.
