neighbours; hence it was not necessary that they should be exhorted with the strict letter of the law, since they had the righteousness of the law in themselves.[642] But, as far as the great majority of men are concerned, they wandered away from God and fell into the sorriest condition. From this moment Irenaeus, keeping strictly to the Old Testament, only concerns himself with the Jewish people. These are to him the representatives of humanity. It is only at this period that the training of the human race is given to them; but it is really the Jewish _nation_ that he keeps in view, and through this he differs very decidedly from such as Barnabas.[643] When righteousness and love to God died out in Egypt, God led his people forth so that man might again become a disciple and imitator of God. He gave him the written law (the Decalogue), which contains nothing else than the moral law of nature that had fallen into oblivion.[644] But when they made to themselves a golden calf and chose to be slaves rather than free men, then the Word, through the instrumentality of Moses, gave to them, as a particular addition, the commandments of slavery (the ceremonial law) in a form suitable for their training. These were bodily commandments of bondage which did not separate them from God, but held them in the yoke. The ceremonial law was thus a pedagogic means of preserving the people from idolatry; but it was at the same time a type of the future. Each constituent of the ceremonial law has this double signification, and both of these meanings originate with God, i.e., with Christ; for "how is Christ the end of the law, if he be not the beginning of it?" ("quomodo finis legis Christus, si non et initium eius esset") IV. 12. 4. Everything in the law is therefore holy, and moreover we are only entitled to blame such portions of the history of the Jewish nation as Holy Scripture itself condemns. This nation was obliged to circumcise itself, keep Sabbaths, offer up sacrifices, and do whatever is related of it, so far as its action is not censured. All this belonged to the state of bondage in which men had a _covenant_ with God and in which they also possessed the right faith in the one God and were taught before hand to follow his Son (IV. 12, 5; "lex praedocuit hominem sequi oportere Christum"). In addition to this, Christ continually manifested himself to the people in the prophets, through whom also he indicated the future and prepared men for his appearance. In the prophets the Son of God accustomed men to be instruments of the Spirit of God and to have fellowship with the Father in them; and in them he habituated himself to enter bodily into humanity.[645] Hereupon began the last stage, in which men, being now sufficiently trained, were to receive the "testamentum libertatis" and be adopted as Sons of God. By the union of the Son of God with the flesh the _agnitio filii_ first became possible to all; that is the fundamental novelty.
