From Peter Enns, on his blog:

But if intention to remain “true” to a “tradition” (which already assumes its non-growth) drives an academic assessment of real evidence (most of which was wholly unavailable when the tradition’s trajectories were set), one runs the risk of adjusting evidence to what one already “knows” to be true. We do not tolerate such sloppy thinking in any other area of human discourse, but when it comes to theological discourse in some circles, it seems to be the preferred method of interaction. When one’s position is by definition unfalsifiable, any meaningful exchange of ideas functionally ceases. Any tradition that aims to promote truth rather than obscure it must be eager to be open to critical evaluation.
