2. Mohler Jr., R. Albert. “Reformist Evangelicalism: A Center without a Circumference.” Page 131–50 in A Confessing Theology for Postmodern Times. Edited by Michael S. Horton. Wheaton: Crossway, 2000.
3. Grudem, Wayne. “Why, When, and for What Should We Draw New Boundaries?” Page 339–70 in Beyond the Bounds: Open Theism and the Undermining of Biblical Christianity. Edited by John Piper and Justin Taylor. Wheaton: Crossway, 2003.
“You can’t mark a boundary line without making distinctions and establishing differences.”
