You can home school your child in Oklahoma, the rules are pretty lax. You just have to make sure your kid studies for 180 days out of the year. There are guidelines and standards but nowhere does it say you can't teach the Bible.
Also Bible History is already an elective in many high schools. It falls under the umbrella of "social studies" which is a broad topic, it includes things like basic psychology and even Prager U is on the official resource list. Our kids did "college prep" which is pretty traditional, it focuses on American and European history ("western civilization") and stuff like that, but my daughter almost talked me into letting her take art history till I found out it was a do-nothing class for seniors then I told her to wait till she got to college.
