Note (return) — Chapter V

Corresponding to the baptismal confession there thus arose at the first a loose system of dogmas which were necessarily devoid of strict style, definite principle, or fixed and harmonious aim. In this form we find them with special plainness in Tertullian.475 This writer was still completely incapable of inwardly connecting his rational (Stoic) theology, as developed by him for apologetic purposes, with the Christological doctrines of the regula fidei, which, after the example of Irenæus, he constructed and defended from Scripture and tradition in opposition to heresy. Whenever he attempts in any place to prove the intrinsic necessity of these dogmas, he seldom gets beyond rhetorical statements, holy paradoxes, or juristic forms. As a systematic thinker, a cosmologist, moralist, and jurist rather than a theosophist, as a churchman, a masterly defender of tradition, as a Christian exclusively guided in practical life by the strict precepts and hopes of the Gospel, his theology, if by that we understand his collective theological disquisitions, is completely devoid of unity, and can only be termed a mixture of dissimilar and, not unfrequently, contradictory propositions, which admit of no comparison with the older theology of Valentinus or the later system of Origen.476 To Tertullian everything lies side by side; problems which chance to turn up are just as quickly solved. The specific faith of Christians is indeed no longer, as it sometimes seems to be in Justin's case, a great apparatus of proof for the doctrines of the only true philosophy; it rather stands, in its own independent value, side by side with these, partly in a crude, partly in a developed form; but inner principles and aims are nearly everywhere sought for in vain.477 In spite of this he possesses inestimable importance in the history of dogma; for he developed and created, in a disconnected form and partly in the shape of legal propositions, a series of the most important dogmatic formulæ, which Cyprian, Novatian, Hosius, and the Roman bishops of the fourth century, Ambrosius and Leo I., introduced into the general dogmatic system of the Catholic Church. He founded the terminology both of the trinitarian and of the Christological dogma; and in addition to this was the first to give currency to a series of dogmatic concepts (satisfacere, meritum, sacramentum, vitium originis etc., etc.). Finally it was he who at the very outset imparted to the type of dogmatic that arose in the West its momentous bias in the direction of auctoritas et ratio, and its corresponding tendency to assume a legal character (lex, formal and material), peculiarities which were to become more and more clearly marked as time went on.478 But, great as is his importance in this respect, it has no connection at all with the fundamental conception of Christianity peculiar to himself, for, as a matter of fact, this was already out of date at the time when he lived. What influenced the history of dogma was not his Christianity, but his masterly power of framing formulæ.
