armoury which supplied the succeeding period with the keenest weapons against herself.[126] The place of the Gospel was taken by a book with exceedingly varied contents, which theoretically acquired the same authority as the Gospel. Still, the Catholic Church never became a religion "of the book," because every inconvenient text could be explained away by the allegoric method, and because the book was not made use of as the immediate authority for the guidance of Christians, this latter function being directly discharged by the rule of faith.[127] In practice it continued to be the rule for the New Testament to take a secondary place in apologetic writings and disputes with heretics.[128] On the other hand it was regarded (1) as the directly authoritative document for the direction of the Christian life,[129] and (2) as the final court of appeal in all the conflicts that arose within the sphere of the rule of faith. It was freely applied in the second stage of the Montanist struggle, but still more in the controversies about Christology, that is, in the conflict with the Monarchians. The apostolic writings belong solely to the Church, because she alone has preserved the apostolic doctrine (regula). This was declared to the heretics and therewith all controversy about Scripture, or the sense of Scripture passages, was in principle declined. But within the Church herself the Holy Scripture was regarded as the supreme and completely independent tribunal against which not even an old tradition could be appealed to; and the rule [Greek: politeuesthai kata to euangelion] ("live according to the Gospel") held good in every respect. Moreover, this formula, which is rarely replaced by the other one, viz., [Greek: kata ten kainen diatheken] ("according to the New Testament"), shows that the words of the Lord, as in the earlier period, continued to be the chief standard of _life and conduct_.
