But the point of this post is to note that Packer had already given us marvelously clear guidance to the above question 50 years ago in his "Fundamentalism" and the Word of God. Some had been arguing that the evangelical view of Scripture, with its view of inerrancy etc, is like the Monophysite heresy, which denies the real humanness of Jesus.
1. At best, the analogy between the divine-human person of the Word made flesh, who is Christ, and the divine-human product of the Word written, which is Scripture, can be only a limited one.--J. I. Packer, "Fundamentalism" and the Word of God (Eerdmans, 1958), 82-84
2. If the point of the analogy is merely that human as well as divine qualities are to be recognized in Scripture, we can only agree, and add that it should be clear from what we have already said--which is no more than Evangelicals have said constantly for over a century--that we do in fact recognize the reality of both.
3. If we are to carry the analogy further, and take it as indicating something about the character which the human element has by virtue of its conjunction with the divine, we must say that it points directly to the fact that, as our Lord, though truly man, was truly free from sin, so Scripture, though a truly human product, is truly free from error. If the critics believe that Scripture, as a human book, errs, they ought, by the force of their own analogy, to believe also that Christ, as man, sinned.
4. If we are to carry the analogy further still, and take it as indicating something about the reality of the union between the divine and the human, we must say that it is in fact the approach of Evangelicals to Scripture which corresponds to Christological orthodoxy, while that of their critics really corresponds to the Nestorian heresy. Nestorianism begins by postulating a distinction between Jesus as a man and the divine Son, whom it regards as someone distinct, indwelling the man; but then it cannot conceive of the real personal identity of the man and the Son.
The right and scriptural way in Christology is to start by recognizing the unity of our Lord's Person as divine and to view His humanity only as an aspect of His Person, existing within it and never, therefore, dissociated from it. Similarly, the right way to think of Scripture is to start from the biblical idea that the written Scriptures as such are 'the oracles of God' and to study their character as a human book only as one aspect of their character as a divine book. Those who start by postulating a distinction between the Bible as a human book and the word of God that is in it are unable, on their own premises, to recognize and exhibit the real oneness of these two things, and when they try to state their mutual relationship they lapse into an arbitrary subjectivism. This is what happens to the critics. (Incidentally, once we see this, we see why they are so ready to accuse Evangelicals of Monophysitism; for Nestorians have always regarded orthodox Christology as Monophysite.)
We must dissent, therefore, from [the] assertion that our task is to discern the divinity in Christ's humanity and the word of God in the fallible words of man, and suggest that it is rather to appreciate the true manhood of the divine Word incarnate and the authentic human character of the inerrant divine Word written.
