I have a pretty enthusiastic American Literature professor here at the University of Southern California. Actually, enthusiastic might not be the right word for it; I think the words "intellectual agitator" best describe his personality. He's one of those guys that want you to question everything that you know and believe, but in a good way.
There is wisdom to do so in a much-neglected portion of Scripture, chapters 14-15 of Paul's Letter to the Romans. Paul introduces a category he calls "disputable matters," which in their time, were toe-curling controversies over big-ticket moral issues. He says that the good news of Jesus lays some demands on us when we're dealing with Uncle Harry and Cousin Mildred.
