A group of Oklahoma parents of public school students, teachers and ministers filed a lawsuit seeking to stop the state’s top education official from forcing schools to incorporate the Bible into lesson plans for students in grades 5 through 12.

Petitioners behind the lawsuit include religious leaders, public school teachers and parents in Oklahoma who argue the measure is harmful.

The Rev. Mitch Randall, one of the plaintiffs cited in the lawsuit, told McClatchy News he was born and raised in Oklahoma, and this mandate is personally offensive to him as a person who identifies with the Southern Baptist tradition and as a citizen of the Muscogee (Creek) nation.
