therefore still free to divest of their direct religious value all realistic and historical elements of the tradition, while still retaining them as parts of a huge apparatus of proof, which accomplished what was really the only thing that many sought in Christianity, viz., the assurance that the theory of the world obtained from other sources was the truth. The danger which here threatened Christianity as a religion was scarcely less serious than that which had been caused to it by the Gnostics. These remodelled tradition, the Apologists made it to some extent inoperative without attacking it. The latter were not disowned, but rather laid the foundation of Church theology, and determined the circle of interests within which it was to move in the future.[6] But the problem which the Apologists solved almost offhand, namely, the task of showing that Christianity was the perfect and certain philosophy, because it rested on revelation, and that it was the highest scientific knowledge of God and the world, was to be rendered more difficult. To these difficulties all that primitive Christianity has up to the present transmitted to the Church of succeeding times contributes its share. The conflict with Gnosticism made it necessary to find some sort of solution to the question, "What is Christian?" and to fix this answer. But indeed the Fathers were not able to answer the question confidently and definitely. They therefore made a selection from tradition and contented themselves with making it binding on Christians. Whatever was to lay claim to authority in the Church had henceforth to be in harmony with the rule of faith and the canon of New Testament Scriptures. That created an entirely new situation for Christian thinkers, that is, for those trying to solve the problem of subordinating Christianity to the Hellenic spirit. That spirit never became quite master of the situation; it was obliged to accommodate itself to it.[7] The work first began with the scientific treatment of individual articles contained in the rule of faith, partly with the view of disproving Gnostic conceptions, partly for the purpose of satisfying the Church's own needs. The framework in which these articles were placed virtually continued to be the apologetic theology, for this maintained a doctrine of God and the world, which seemed to correspond to the earliest tradition as much as it ran counter to the Gnostic theses. (Melito), Irenaeus, Tertullian and Hippolytus, aided more or less by tradition on the one hand and by philosophy on the other, opposed to the Gnostic dogmas about Christianity the articles of the baptismal confession interpreted as a rule of faith, these articles being developed into doctrines. Here they undoubtedly learned very much from the Gnostics and Marcion. If we define ecclesiastical dogmas as propositions handed down in the creed of the Church, shown to exist in the Holy Scriptures of both Testaments, and rationally reproduced and
