In the Old Testament the three classes or canons have been generally estimated by the Jews according to their respective antiquity; though the sacrificial worship enjoined in the Pentateuch never formed an essential part of the Jewish religion; the best prophets having set small value upon it. The pure monotheistic doctrine of these last writers, chiefly contained in the second canon, lifts that class up to the highest rank; yet the Decalogue in the Pentateuch is sufficient to stamp the first canon with great worth. It must be confessed, however, that the Mosaic law was meagre, in the domain of pure ethics; and that it promoted among the people a slavish spirit of positivism by laying more stress on acts than dispositions, and insisting on small regulations. For this reason, the prophets combated its narrow externality. The three canons were regarded with a degree of veneration corresponding to the order in which they stand. To apportion their respective values to the individual parts of them is a difficult task. As to the New Testament writings, we think that some of them might conveniently occupy the position of _deutero-canonical_, equivalent to those of the Old Testament having that title. We allude to 2 and 3 John, Jude, James, 2 Peter, the Revelation. It is true that a few of these were prior in time to some of the universally-received gospels or epistles; but time is not an important factor in a good classification. Among the Pauline epistles themselves, classification might be adopted; for the pastoral letters are undoubtedly post-Pauline, and inferior to the authentic ones. In classifying the New Testament writings, three things might be considered—the reception they met with from the first, their authenticity, above all, their internal excellence. The subject is not easy, because critics are not universally agreed about the proper rank and authenticity of a few documents. The Epistle to the Colossians, for example, creates perplexity; that to the Ephesians is less embarrassing, its post-Pauline origin being tolerably clear. What is wanted is a rational historic criticism to moderate the theological hypothesis with which the older Protestants set out, the supernatural inspiration of the books, their internal inseparability, and their direct reference to the work of salvation. It must be allowed that many points are independent of dogmatics; and that the right decision in things historical may be reached apart from any ecclesiastical standpoint.
