The youth Bible club "Owasso Kids for Christ" has filed suit in Oklahoma, claiming a local school district violated the group's constitutional rights.
The lawsuit against Owasso Public Schools was filed in federal court this week by the Alliance Defense Fund.
The group said the school district banned its students from promoting their events, like before-school Bible study.
The lawsuit also claimed Owasso Kids for Christ wasn't allowed to participate in a school Open House.
According to World Net Daily, the lawsuit stems from an April incident in which club members wanted to send their peers home with a flyer that contained the phrase, "Reaching the world for Christ!"
But Superintendent Clark Ogilvie said the flyer violated district policies.
In a statement, Ogilvie said the issue was "taken out of context."
Owasso Public Schools has a general policy stating, "No literature will be distributed that contains primarily religious, objectionable, or political overtones which may be beneficial to any particular group or business at the expense of others."
