Dobson took aim at examples Obama cited in asking which Biblical passages should guide public policy - chapters like Leviticus, which Obama said suggests slavery is OK and eating shellfish is an abomination, or Jesus' Sermon on the Mount, "a passage that is so radical that it's doubtful that our own Defense Department would survive its application."

"Folks haven't been reading their Bibles," Obama said.

Dobson and Minnery accused Obama of wrongly equating Old Testament texts and dietary codes that no longer apply to Jesus' teachings in the New Testament.

"I think he's deliberately distorting the traditional understanding of the Bible to fit his own worldview, his own confused theology," Dobson said.
