Now it is this very reality and depth, and hence the rich Unity, the growth, variety, and manifold fruitfulness of His life and teaching, which explain, as a necessity and an advantage, that we should have those successive pictures and conceptions of Him which already the New Testament presents. _Because_ Socrates was so great and impressive, we have the two successive, remarkably divergent, portraits of him: the external, historical, by Xenophon; the internal, typical one, by Plato; and _that_ is all. _Because_ our Lord is so unspeakably greater, and continues, with inexhaustible freshness, to be the very life of the lives of Christians, we have three or four classical portraits of Him in the New Testament; and, in a certain true manner and degree, each successive age, in a measure each single soul, forms, and has to form, its own picture of Him. We can roughly classify these pictures under the three successive types of the “Petrine,” the “Pauline,” and the “Joannine,” provided we do not forget that the precise limits of the first of these divisions are difficult to draw, and that there are growths and diversities of aspect to be found within the Pauline type. For the Petrine type will here be sought in the Synoptic Gospels, and in particular in those accounts and sayings there which appear to give us the closest reproduction of our Lord’s very acts and words and of the impressions produced by these upon the original witnesses. The Pauline type will embrace four main stages or developments: that of the four or five of the earlier Epistles--the two to the Thessalonians and those to the Galatians, Corinthians, and Romans; that of the Epistles of the Captivity, Colossians, Philippians, Ephesians; that of the Pastoral Epistles; and that of the Epistle to the Hebrews. And even in the least diversified, the Joannine type, there is the variation between the Gospel and Epistles on the one hand, and the Apocalypse on the other. But taking these three types as each a unity, we shall hardly be guilty of an empty schematization, if the Petrine or Primitive-Apostolic group represents to us mainly the simplest statement of the external facts, and specially of the traditional, the Jewish side of our Lord’s teaching; and if the Pauline and Joannine groups each mainly represent to us, in various degrees and combinations, the two manners in which the hidden significance of these facts, as intended for all men and for all time, can be penetrated, viz. by thought and speculation, and by feeling and operative experience.
