Note (return) — Chapter I

2. The degree of influence exercised by particular ecclesiastics on the development of the Church and its doctrines is also obscure and difficult to determine. As they were compelled to claim the sanction of tradition for every innovation they introduced, and did in fact do so, and as every fresh step they took appeared to themselves necessary only as an explanation, it is in many cases quite impossible to distinguish between what they received from tradition and what they added to it of their own. Yet an investigation from the point of view of the historian of literature shows that Tertullian and Hippolytus were to a great extent dependent on Irenæus. What amount of innovation these men independently contributed can therefore still be ascertained. Both are men of the second generation. Tertullian is related to Irenæus pretty much as Calvin to Luther. This parallel holds good in more than one respect. First, Tertullian drew up a series of plain dogmatic formulæ which are not found in Irenæus and which proved of the greatest importance in succeeding times. Secondly, he did not attain the power, vividness, and unity of religious intuition which distinguish Irenæus. The truth rather is that, just because of his forms, he partly destroyed the unity of the matter and partly led it into a false path of development. Thirdly, he everywhere endeavoured to give a conception of Christianity which represented it as the divine law, whereas in Irenæus this idea is overshadowed by the conception of the Gospel as real redemption. The main problem therefore resolves itself into the question as to the position of Irenæus in the history of the Church. To what extent were his expositions new, to what extent were the standards he formulated already employed in the Churches, and in which of them? We cannot form to ourselves a sufficiently vivid picture of the interchange of Christian writings in the Church after the last quarter of the second century.17 Every important work speedily found its way into the churches of the chief cities in the Empire. The diffusion was not merely from East to West, though this was the general rule. At the beginning of the fourth century there was in Cæsarea a Greek translation of Tertullian's Apology and a collection of Cyprian's epistles.18 The influence of the Roman Church extended over the greater part of Christendom. Up till about the year 260 the Churches in East and West had still in some degree a common history.
