I think Bible as literature classes in schools should be supported by all Christians. I have found most people who are hostile to Christianity have worse than zero Bible knowledge. They have popular misconceptions of the Bible as their only Biblical knowledge.
Would captive students in the public schools be taught the blasphemous documentary hypothesis, or that the Bible is mere "literature" or "mythology?" I am adamantly opposed to any such thing.
Religious Truth is no less true than anay other kind. It is not speculative or subjective and it deserves to be taught as fact.
