I wholeheartedly support the endeavor. Seriously.
Schools are about educating kids. The Bible falls within the “realm of knowledge,” i.e. it's yet another thing for them to learn about.
As is unfiltered, objective sex education, for example.
Public school Bible classes are electives, and must remain that way if the schools are going to maintain church-state separation.
Further, the classes must not be taken as license for students or teachers to go around trying to convert or witness to others at their school.
And additional courses along similar lines, e.g. the Talmud or Quran, should in all fairness be considered.
Though I have written vociferously against prayer in public schools, this is different. It’s a class, not a conformation exercise that students are required to participate in en masse, like morning prayers or the Pledge of Allegiance.
Nor does my support for Bible classes contradict my rejection of the teaching of Intelligent Design in science classes (here, here and here). ID isn’t science and doesn’t belong in any science class. If you want to have an “unsupportable theories” class, however, have at it.
By allowing Bible classes in public schools, we’ll steal some of the divine thunder of the “Christianity is under attack in America” crowd. It may be just what we need to derail their self-pitying, self-serving crusade and pacify them for a little while.
