conception that destroyed the unity of origin of the Old Testament and the old idea which neither acknowledged various constituents in the book nor recognised the peculiarities of Christianity. We are therefore justified in regarding this history of salvation approved by the Church, as well as the theological propositions of Irenaeus and Tertullian generally, as a Gnosis "toned down" and reconciled with Monotheism. This is shown too in the faint gleam of a historical view that still shines forth from this "history of salvation" as a remnant of that bright light which may be recognised in the Gnostic conception of the Old Testament.[635] Still, it is a striking advance that Irenaeus has made beyond Justin and especially beyond Barnabas. No doubt it is mythological history that appears in this history of salvation and the recapitulating story of Jesus with its saving facts that is associated with it; and it is a view that is not even logically worked out, but ever and anon crossed by the proof from prophecy; yet for all that it is development and history. The fundamental features of Irenaeus' conception are as follow: The Mosaic law and the New Testament dispensation of grace both emanated from one and the same God, _and were granted for the salvation of the human race in a form appropriate to the times_.[636] The two are in part different; but the difference must be conceived as due to causes[637] that do not affect the unity of the author and of the main points.[638] We must make the nature of God and the nature of man our point of departure. God is always the same, man is ever advancing towards God; God is always the giver, man always the receiver;[639] God leads us ever to the highest goal; man, however, is not God from the beginning, but is destined to incorruptibility, which he is to attain step by step, advancing from the childhood stage to perfection (see above, p. 267 f.). This progress, conditioned by the nature and destination of man, is, however, dependent on the revelation of God by his Son, culminating in the incarnation of the latter and closing with the subsequent bestowal of the Spirit on the human race. In Irenaeus therefore the place of the many different revelation-hypostases of the Valentinians is occupied by the one God, who stoops to the level of developing humanity, accommodates himself to it, guides it, and bestows on it increasing revelations of grace.[640] The fundamental knowledge of God and the moral law of nature, i.e., natural morality, were already revealed to man and placed in his heart[641] by the creator. He who preserves these, as for example the patriarchs did, is justified. (In this case Irenaeus leaves Adam's sin entirely out of sight). But it was God's will to bring men into a higher union with himself; wherefore his Son descended to men from the beginning and accustomed himself to dwell among them. The patriarchs loved God and refrained from injustice towards their
