But even apart from the content which Christianity here received, this process in itself represents a progressive secularising of the Church, This would be self-evident enough, even if it were not confirmed by noting the fact that the process had already been to some extent anticipated in the so-called Gnosticism (See vol. I. p. 253 and Tertullian, de praescr. 35). But the element which the latter lacked, namely, a firmly welded, suitably regulated constitution, must by no means be regarded as one originally belonging and essential to Christianity. The depotentiation to which Christianity was here subjected appears still more plainly in the facts, that the Christian hopes were deadened, that the secularising of the Christian life was tolerated and even legitimised, and that the manifestations of an unconditional devotion to the heavenly excited suspicion or were compelled to confine themselves to very narrow limits. But these considerations are scarcely needed as soon as we turn our attention to the second series of developments that make up the history of this period. The Church did not merely set up dykes and walls against Gnosticism in order to ward it off externally, nor was she satisfied with defending against it the facts which were the objects of her belief and hope; but, taking the creed for granted, she began to follow this heresy into its own special territory and to combat it with a scientific theology. That was a necessity which did not first spring from Christianity's own internal struggles. It was already involved in the fact that the Christian Church had been joined by cultured Greeks, who felt the need of justifying their Christianity to themselves and the world, and of presenting it as the desired and certain answer to all the pressing questions which then occupied men's minds.
