A Florida judge is considering whether her order banning school prayer is legal.
U.S. District Judge Casey Rodgers issued the order earlier this year after the American Civil Liberties Union challenged Pace High School in Pensacola.
The order banned school officials from praying or arranging for prayer during school events.
The ACLU accused the school of endorsing religion after an athletic director prayed at an after-school event with other adults.
The Liberty Counsel is challenging the order in federal court. The group's Mat Staver told CBN News the outcome has national implications.
"This is a very broad order that not only covers activities during school hours, but after school hours and on their own time," he explained. "This is an attempt that I've never seen before, so broad it really is an attempt to criminalize Christianity."
Rodgers is expected to rule on the order this week.
