The movement which resulted in the Catholic Church owes its right to a place in the history of Christianity to the victory over Gnosticism and to the preservation of an important part of early Christian tradition. If Gnosticism in all its phases was the violent attempt to drag Christianity down to the level of the Greek world, and to rob it of its dearest possession, belief in the Almighty God of creation and redemption, then Catholicism, inasmuch as it secured this belief for the Greeks, preserved the Old Testament, and supplemented it with early Christian writings, thereby saving--as far as documents, at least, were concerned--and proclaiming the authority of an important part of primitive Christianity, must in one respect be acknowledged as a conservative force born from the vigour of Christianity. If we put aside abstract considerations and merely look at the facts of the given situation, we cannot but admire a creation which first broke up the various outside forces assailing Christianity, and in which the highest blessings of this faith have always continued to be accessible. If the founder of the Christian religion had deemed belief in the Gospel and a life in accordance with it to be compatible with membership of the Synagogue and observance of the Jewish law, there could at least be no impossibility of adhering to the Gospel within the Catholic Church. Still, that is only one side of the case. The older Catholicism never clearly put the question, "What is Christian?" Instead of answering that question it rather laid down rules, the recognition of which was to be the guarantee of Christianism. This solution of the problem seems to be on the one hand too narrow and on the other too broad. Too narrow, because it bound Christianity to rules under which it necessarily languished; too broad, because it did not in any way exclude the introduction of new and foreign conceptions. In throwing a protective covering round the Gospel, Catholicism also obscured it. It preserved Christianity from being hellenised to the most extreme extent, but, as time went on, it was forced to admit into this religion an ever greater measure of secularisation. In the interests of its world-wide mission it did not indeed directly disguise the terrible seriousness of religion, but, by tolerating a less strict ideal of life, it made it possible for those less in earnest to be considered Christians, and to regard themselves as such. It permitted the genesis of a Church, which was no longer a communion of faith, hope, and discipline, but a political commonwealth in which the Gospel merely had a place beside other things.[3] In ever increasing measure it invested all the forms which this secular commonwealth required with apostolic, that is, indirectly, with divine authority. This course disfigured Christianity and made a knowledge of what is Christian an obscure and difficult matter. But, in Catholicism, religion for the first time obtained a formal dogmatic system.
