The permanence of the communities, however, depended on the discovery of such a standard. They were no longer held together by the _conscientia religionis_, the _unitas disciplinae_, and the _foedus spei_. The Gnostics were not solely to blame for that. They rather show us merely the excess of a continuous transformation which no community could escape. The gnosis which subjected religion to a critical examination awoke in proportion as religious life from generation to generation lost its warmth and spontaneity. There was a time when the majority of Christians knew themselves to be such, (1) because they had the "Spirit" and found in that an indestructible guarantee of their Christian position, (2) because they observed all the commandments of Jesus ([Greek: entolai Iesou]). But when these guarantees died away, and when at the same time the most diverse doctrines that were threatening to break up the Church were preached in the name of Christianity, the fixing of tradition necessarily became the supreme task. Here, as in every other case, the tradition was not fixed till after it had been to some extent departed from. It was just the Gnostics themselves who took the lead in a fixing process, a plain proof that the setting up of dogmatic formulae has always been the support of new formations. But the example set by the Gnostics was the very thing that rendered the problem difficult. Where was a beginning to be made? "There is a kind of unconscious logic in the minds of masses of men when great questions are abroad, which some one thinker throws into suitable form."[33] There could be no doubt that the needful thing was to fix what was "apostolic," for the one certain thing was that Christianity was based on a divine revelation which had been transmitted through the medium of the Apostles to the Churches of the whole earth. It certainly was not a single individual who hit on the expedient of affirming the fixed forms employed by the Churches in their solemn transactions to be apostolic in the strict sense. It must have come about by a natural process. But the confession of the Father, Son, and Spirit and the _kerygma_ of Jesus Christ had the most prominent place among these forms. The special emphasising of these articles, in opposition to the Gnostic and Marcionite undertakings, may also be viewed as the result of the "common sense" of all those who clung to the belief that the Father of Jesus Christ was the creator of the world, and that the Son of God really appeared in the flesh. But that was not everywhere sufficient, for, even admitting that about the period between 150 and 180 A.D. all the Churches had a fixed creed which they regarded as apostolic in the strict sense--and this cannot be proved,--the most dangerous of all Gnostic schools, viz., those of Valentinus, could recognise this creed, since they already possessed the art of explaining a given text in whatever way they chose. What was needed was an apostolic creed
