D. A. Carson, “On Drawing Lines, When Drawing Lines Is Rude,” ch. 8 in The Gagging of God: Christianity Confronts Pluralism (Grand Rapids: Zondervan, 1996), 347–67 (numbering added):

- The distinction between orthodoxy and heresy models it.
- The plurality of errors calls for it.
- The entailments of the gospel confront our culture—and must be lived out.
