Several Oklahoma schools are speaking out against State Superintendent Ryan Walters’ directive to teach the Bible in public school grades 5 through 12.

Walters recently released guidelines on his controversial Bible mandate in public schools after ordering educators to incorporate the religious text into their lessons, arguing that the Bible is necessary to ensure “students grasp the core values and historical context of our country.”

In a June 27 meeting, Walters spoke on the requirement, saying, “every teacher and every classroom in the state will have a Bible in the classroom and will be teaching from the Bible in the classroom.”

The order was followed by intense backlash from civil liberties groups and the Oklahoma Education Association – a collective of educators, administrators and other school employees — who say it infringes on students’ and educators’ freedom of religion.

Now, several Oklahoma schools have publicly stated that there will not be any changes to their curriculum and that they will continue to adhere to current school standards despite Walters’ recently announced guidelines.

In a July 25 statement, Owasso Public Schools Superintendent Margaret Coates said the district “will continue to adhere to the curriculum and instructional materials previously adopted by the district.”

“As a public school system, it is crucial that we maintain neutrality and objectivity in our curriculum and instructional practices,” Coates continued.

Many school district superintendents noted that Walters cannot solely mandate curriculum or instructional resources — pointing to the state law that requires standards to receive legislative approval on a six-year cycle and state statutes that give local districts the ability to determine reading and instructional materials.

Currently, the 2019 approved Oklahoma state education standards include religion as it relates to its historical role and to cultures around the world. According to the current “World History Content Standards,” educators are to discuss “the origins, major beliefs, spread and lasting impact of the world’s major religions and philosophies, including Judaism, Hinduism, Buddhism, Christianity, Islam, Confucianism, and Sikhism.”

Stillwater Public Schools Superintendent Uwe Gordon said in an online statement that the school will neither be purchasing class copies of the Bible nor will it deliver lessons from Bibles or any other religious text.

“SPS prides itself on being respectful of the myriad religions, cultures, traditions, worldviews, and belief systems inherent in our community,” said Gordon. “The district also holds itself to adherence with the state’s established academic standards and the laws of the land.”

Gordon also reaffirmed students’ abilities to pray in schools, read religious texts on their own, wear religious garb and meet with religious student-led clubs.

In a statement on the Bixby Public Schools district website, Superintendent Rob Miller said he agrees with Walters on “the importance of studying the role of religion in historical and cultural contexts.”

However, the district argues that the teaching of any specific religious doctrine or ideology is not part of the current state standards. Therefore, Bixby Public Schools said it will not change its curriculum.

Moore Public Schools Superintendent Robert Romines clarified in a statement on July 18 that while students should learn about religion’s role in historical and cultural contexts, the teaching of specific religious doctrines or practices is not a part of the current education standards.

“Our goal is to continue providing a respectful environment that acknowledges various perspectives while adhering to the set and approved Oklahoma educational standards,” said Romines.

Walters told ABC News in a statement: “Some Oklahoma educators have indicated they won’t follow the law and Oklahoma standards, so let me be clear: they will comply, and I will use every means to make sure of it.”

ABC News asked for clarification on the consequences educators or schools could face if they did not comply, but his office did not provide a response.

Walters’ guidelines require educators to incorporate the Bible by looking at “only its historical, literary and secular benefits” by noting the Bible’s influence on Western civilization, American history, literature, art and music.

The guidelines also repeatedly state that the Bible “is not to be used for religious purposes such as preaching, proselytizing or indoctrination” and that “maintaining neutrality and objectivity is crucial.”

When it comes to the constitutionality of religion in schools, the U.S. Supreme Court has ruled against mandated religious practices or texts in schools.

In 1980, the U.S. Supreme Court determined that Kentucky’s then-law requiring that a copy of the Ten Commandments be posted in public classrooms “had no secular legislative purpose” and was “plainly religious in nature.”

Nearly 20 years before that, the Supreme Court ruled that school-sponsored devotional prayer and Bible readings in public schools are unconstitutional.

Local news outlet Tulsa World recently reported comments from Walters in which he appeared to welcome lawsuits against the Bible directive, in hopes that the U.S. Supreme Court could overturn previous precedent on the separation of church and state.

Miller, from Bixby Public Schools, noted that these comments seem to be a “tacit acknowledgment that this directive may not pass constitutional muster based on current statutes and legal precedent and may require a future review by the Supreme Court.”

“Bixby Schools will continue to comply with existing case law to ensure that the rights of our students and employees are fully protected,” Miller said.
