We have spoken thus far as if the whole biblical-critical problem had been that of the New Testament. In reality the same impulses which had opened up that question to the minds of men had set them working upon the problem of the Old Testament as well. We have seen how the Christians made for themselves a canon of the New Testament. By the force of that conception of the canon, and through the belief that, almost in a literal sense, God was the author of the whole book, the obvious differences among the writings had been obscured. Men forgot the evolution through which the writings had passed. The same thing had happened for the Old Testament in the Jewish synagogues and for the rabbis before the Christian movement. When the Christians took over the Old Testament they took it over in this sense. It was a closed book wherein all appreciation of the long road which the religion of Israel had traversed in its evolution had been lost. The relation of the old covenant to the new was obscured. The Old Testament became a Christian book. Not merely were the Christian facts prophesied in the Old Testament, but its doctrines also were implied. Almost down to modern times texts have been drawn indifferently from either Testament to prove doctrine and sustain theology. Moses and Jesus, prophets and Paul, are cited to support an argument, without any sense of difference. What we have said is hardly more true of Augustine or Anselm than of the classic Puritan divines. This was the state of things which the critics faced. The Old Testament critical movement is a parallel at all points of the one which we have described in reference to the New. Of course, elder scholars, even Spinoza, had raised the question as to the Mosaic authorship of certain portions of the Pentateuch. Roman Catholic scholars in the seventeenth century, for whom the stringent theory of inspiration had less significance than for Protestants, had set forth views which showed an awakening to the real condition. Yet, at the beginning of the nineteenth century, no one would have forecast a revolution in opinion which would recognise the legendary quality of considerable portions of the Pentateuch and historical books, which would leave but little that is of undisputed Mosaic authorship, which would place the prophets before the law, which would concede the growth of the Jewish canon, which would perceive the relation of Judaism to the religions of the other Semite peoples and would seek to establish the true relation of Judaism to Christianity.
