In his chapter on the doctrine of Scripture in the helpful book Reforming or Conforming, theologian Paul Wells writes:
The analogy is not really an analogy at all in the formal sense of the word, since the mystery of the personal union of the two natures in Christ does not serve to shed light on the nature of the union in the divine-human word of Scripture. Christ and Scripture are not equivalent realities as there is but one hypostatic union. Following along this line, it can be said that "an incarnational model may not be the best because, whereas with Christ's incarnation there is one person with two natures, with Scripture there are two persons (God and the human prophet) and one nature (the one Scriptural speech act). Thus to try to make the analogy may be like comparing apples to oranges" (Henri Blocher from a review of Inspiration and Incarnation in Journal of the Evangelical Theological Society).Apples and oranges indeed. For the errantist the incarnational model serves as a way to explain the Bible's supposed errors. But what does this say about their understanding of incarnation? We already know that their doctrine of inspiration does not allow for God to ensure that His words were acurately written through human authors. Could it be that their inderstanding of incarnation allows for something less than a perfect Christ? I am only speculating. It just seems strange that a miracle as awesome as the incarnation of God in human flesh would be used as analogy to promote the idea that the Bible errs.
