Amen. When a teacher proposes something new and unfamiliar to those of us who have been around a little while, he had darn well better support his thesis with more than a quote or two from some extrabiblical source.

I think it is not possible to exegete from the scriptures that the Sadducees were motivated entirely by politics, and a teacher who would assert such a thing has exceeded the teachings of scripture and is out of bounds.
