So, there’s this site called National Council on Bible Curriculum in Public Schools, and it tries to say some non-threatening stuff:

The curriculum for the program shows a concern to convey the content of the Bible as compared to literature and history. The program is concerned with education rather than indoctrination of students. The central approach of the class is simply to study the Bible as a foundation document of society, and that approach is altogether appropriate in a comprehensive program of secular education.

But I’m sure there’s no long-term goal for any of this.
