Despite the First Amendment’s prohibition on government entities favoring one religion over others, Walters defended his decision by citing a state law about historical documents. He emphasized that the Bible holds significant importance to the foundation of America, according to Tulsa CBS affiliate KOTV.

“The Bible is a crucial historical and cultural reference point,” Walters stated. “Without a basic understanding of it, Oklahoma students cannot fully grasp the foundation of our nation. This is why Oklahoma educational standards include its instruction. This directive is not just about education; it is vital for ensuring our students understand the core values and historical context of our country.”

In his memo, Walters instructed teachers to include the Bible in lessons for certain grade levels, specifically mentioning grades 5 through 12.

This directive was issued just 10 days after Louisiana became the first state to require the Ten Commandments to be displayed in every public school classroom. The ACLU is currently challenging this rule in court.

HuffPost contacted the Oklahoma Board of Education to ask if other religious historical documents will also be required in classes, but did not receive an immediate response.

Following the memo’s release, Walters addressed the backlash, stating, “The left is upset, but one cannot rewrite history.”
