Educators in Oklahoma are refusing a state order to incorporate the Bible into their lesson plans, setting up an inevitable showdown with the start of the school year just weeks away.

Ryan Walters, the state superintendent of public instruction, last week released guidelines to schools for how they should be integrating the Bible into classrooms, saying educators who are against the initiative “will comply, and I will use every means to make sure of it.”

The message from some schools in the state: Bring it on.
