The Tennessee Board of Education has approved guidelines on how to teach the Bible in public high schools. The curriculum approved last week is in response to 2008 legislation, which authorized the state to create a course for a “nonsectarian, nonreligious academic study of the Bible.” State officials said they tried to develop principles that are safe from court challenges. But some are concerned a state-approved Bible course could violate church and state separation, depending on who is teaching it. Hedy Weinberg is director of the American Civil Liberties Union of Tennessee. She told The Tennessean that the state seemed sensitive to concerns that the classes could be used to try to convert individuals. However, there are few details on how the classes will be run.
