CHAPTER V.

THE BEGINNINGS OF AN ECCLESIASTICO-THEOLOGICAL INTERPRETATION AND REVISION OF THE RULE OF FAITH IN OPPOSITION TO GNOSTICISM ON THE BASIS OF THE NEW TESTAMENT AND THE CHRISTIAN PHILOSOPHY OF THE APOLOGISTS: MELITO, IRENÆUS, TERTULLIAN, HIPPOLYTUS, NOVATIAN.[⁴⁶⁰]

1. The theological position of Irenæus and the later contemporary Church teachers.

Gnosticism and the Marcionite Church had compelled orthodox Christianity to make a selection from tradition and to make this binding on Christians as an apostolical law. Everything that laid claim to validity had henceforth to be legitimised by the faith, i.e., the baptismal confession and the New Testament canon of Scripture (see above, chap. 2, under A and B). However, mere "prescriptions" could no longer suffice here. But the baptismal confession was no "doctrine;" if it was to be transformed into such it required an interpretation. We have shown above that the interpreted baptismal confession was instituted as the guide for the faith. This interpretation took its matter from the sacred books of both Testaments. It owed its guiding lines, however, on the one hand to philosophical theology, as set forth by the Apologists, and on the other to the earnest endeavour to maintain and defend against all attacks the traditional convictions and hopes of believers, as professed in the past generation by the enthusiastic forefathers of the Church. In addition to this, certain interests, which had found expression in the speculations of the so-called Gnostics, were adopted in an increasing degree among all thinking Christians, and also could not but influence the ecclesiastical teachers.[⁴⁶¹] The theological labours, thus initiated, accordingly bear the impress of great uniqueness and complexity. In the first place, the old Catholic Fathers, Melito,[⁴⁶²] Rhodon,[⁴⁶³] Irenæus, Hippolytus, and Tertullian were in every case convinced that all their expositions contained the universal Church faith itself and nothing else. Though the faith is identical with the baptismal confession, yet every interpretation of it derived from the New Testament is no less certain than the shortest formula.[⁴⁶⁴] The creation of the New Testament furnished all at once a quite unlimited multitude of conceptions, the whole of which appeared as "doctrines" and offered themselves for incorporation with the "faith."[⁴⁶⁵] The limits of the latter therefore seem to be indefinitely extended, whilst on the other hand tradition, and polemics too in many cases, demanded an adherence to the shortest formula. The oscillation between this brief formula, the contents of which, as a rule, did not suffice, and that fulness, which admitted of no bounds at all, is characteristic of the old Catholic Fathers we have mentioned. In the second place, these fathers felt quite as much need of a rational proof in their arguments with their christian opponents, as they did while contending with the heathen;[⁴⁶⁶] and, being themselves children of their time, they required this proof for their own assurance and that of their fellow-believers. The epoch in which men appealed to charisms, and "knowledge" counted as much as prophecy and vision, because it was still of them same nature, was in the main a thing of the past.[⁴⁶⁷] Tradition and reason had taken the place of charisms as courts of appeal. But this change had neither come to be clearly recognized,[⁴⁶⁸] nor was the right and scope of rational theology alongside of tradition felt to be a problem. We can indeed trace the consciousness of the danger in attempting to introduce new termini and regulations not prescribed by the Holy Scriptures.[⁴⁶⁹] The bishops themselves in fact encouraged this apprehension in order to warn people against the Gnostics,[⁴⁷⁰] and after the deluge of heresy, representatives of Church orthodoxy looked with distrust on every philosophic-theological formula.[⁴⁷¹] Such propositions of rationalistic theology as were absolutely required, were, however, placed by Irenæus and Tertullian on the same level as the hallowed doctrines of tradition, and were not viewed by them as something of a different nature. Irenæus uttered most urgent warnings against subtle speculations;[⁴⁷²] but yet, in the naivest way, associated with the faithfully preserved traditional doctrines and fancies of the faith theories which he likewise regarded as tradition and which, in point of form, did not differ from those of the Apologists or Gnostics.[⁴⁷³] The Holy Scriptures of the New Testament were the basis on which Irenæus set forth the most important doctrines of Christianity. Some of these he stated as they had been conceived by the oldest tradition (see the eschatology), others he adapted to the new necessities. The qualitative distinction between the fides credenda and theology was noticed neither by Irenæus nor by Hippolytus and Tertullian. According to Irenæus I. 10. 3 this distinction is merely quantitative. Here faith and theological knowledge are still completely intermixed. Whilst stating and establishing the doctrines of tradition with the help of the New Testament, and revising and fixing them by means of intelligent deduction, the Fathers think they are setting forth the faith itself and nothing else. Anything more than this is only curiosity not unattended with danger to Christians. Theology is interpreted faith.[⁴⁷⁴]

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.

It is different with Irenæus. The Christianity of this man proved a decisive factor in the history of dogma in respect of its content. If Tertullian supplied the future Catholic dogmatic with the most important part of its formulæ, Irenæus clearly sketched for it its fundamental idea, by combining the ancient notion of salvation with New Testament (Pauline) thoughts.[⁴⁷⁹] Accordingly, as far as the essence of the matter is concerned, the great work of Irenæus is far superior to the theological writings of Tertullian. This appears already in the task, voluntarily undertaken by Irenæus, of giving a relatively complete exposition of the doctrines of ecclesiastical Christianity on the basis of the New Testament, in opposition to heresy. Tertullian nowhere betrayed a similar systematic necessity, which indeed, in the case of the Gallic bishop too, only made its appearance as the result of polemical motives. But Irenæus to a certain degree succeeded in amalgamating philosophic theology and the statements of ecclesiastical tradition viewed as doctrines. This result followed (1) because he never lost sight of a fundamental idea to which he tried to refer everything, and (2) because he was directed by a confident view of Christianity as a religion, that is, a theory of its purpose. The first fundamental idea, in its all-dominating importance, was suggested to Irenæus by his opposition to Gnosticism. It is the conviction that the Creator of the world and the supreme God are one and the same.[⁴⁸⁰] The other theory as to the aim of Christianity, however, is shared by Irenæus with Paul, Valentinus, and Marcion. It is the conviction that Christianity is real redemption, and that this redemption was only effected by the appearance of Christ. The working out of these two ideas is the most important feature in Irenæus' book. As yet, indeed, he by no means really succeeded in completely adapting to these two fundamental thoughts all the materials to be taken from Holy Scripture and found in the rule of faith; he only thought with systematic clearness within the scheme of the Apologists. His archaic eschatological disquisitions are of a heterogeneous nature, and a great deal of his material, as, for instance, Pauline formulæ and thoughts, he completely emptied of its content, inasmuch as he merely contrived to turn it into a testimony of the oneness and absolute causality of God the Creator; but the repetition of the same main thoughts to an extent that is wearisome to us, and the attempt to refer everything to these, unmistakably constitute the success of his work.[⁴⁸¹] God the Creator and the one Jesus Christ are really the middle points of his theological system, and in this way he tried to assign an intrinsic significance to the several historical statements of the baptismal confession. Looked at from this point of view, his speculations were almost of an identical nature with the Gnostic.[⁴⁸²] But, while he conceives Christianity as an explanation of the world and as redemption, his Christocentric teaching was opposed to that of the Gnostics. Since the latter started with the conception of an original dualism they saw in the empiric world a faulty combination of opposing elements,[⁴⁸³] and therefore recognised in the redemption by Christ the separation of what was unnaturally united. Irenæus, on the contrary, who began with the idea of the absolute causality of God the Creator, saw in the empiric world faulty estrangements and separations, and therefore viewed the redemption by Christ as the reunion of things unnaturally separated—the "recapitulatio" (ανακεφαλαιωσις).[⁴⁸⁴] This speculative thought, which involved the highest imaginable optimism in contrast to Gnostic pessimism, brought Irenæus into touch with certain Pauline trains of thought,[⁴⁸⁵] and enabled him to adhere to the theology of the Apologists. At the same time it opened up a view of the person of Christ, which supplemented the great defect of that theology,[⁴⁸⁶] surpassed the Christology of the Gnostics,[⁴⁸⁷] and made it possible to utilise the Christological statements contained in certain books of the New Testament.[⁴⁸⁸]

So far as we know at least, Irenæus is the first ecclesiastical theologian after the time of the Apologists (see Ignatius before that) who assigned a quite specific significance to the person of Christ and in fact regarded it as the vital factor.[⁴⁸⁹] That was possible for him because of his realistic view of redemption. Here, however, he did not fall into the abyss of Gnosticism, because, as a disciple of the "elders", he adhered to the early-Christian eschatology, and because, as a follower of the Apologists, he held, along with the realistic conception of salvation, the other dissimilar theory that Christ, as the teacher, imparts to men, who are free and naturally constituted for fellowship with God, the knowledge which enables them to imitate God, and thus by their own act to attain communion with him. Nevertheless to Irenæus the pith of the matter is already found in the idea that Christianity is real redemption, i.e., that the highest blessing bestowed in Christianity is the deification of human nature through the gift of immortality, and that this deification includes the full knowledge and enjoying of God (visio dei). This conception suggested to him the question as to the cause of the incarnation as well as the answer to the same. The question "cur deus—homo", which was by no means clearly formulated in the apologetic writings, in so far as in these "homo" only meant appearance among men, and the "why" was answered by referring to prophecy and the necessity of divine teaching, was by Irenæus made the central point. The reasons why the answer he gave was so highly satisfactory may be stated as follows: (1) It proved that the Christian blessing of salvation was of a specific kind. (2) It was similar in point of form to the so-called Gnostic conception of Christianity, and even surpassed it as regards the promised extent of the sphere included in the deification. (3) It harmonised with the eschatological tendency of Christendom, and at the same time was fitted to replace the material eschatological expectations that were fading away. (4) It was in keeping with the mystic and Neoplatonic current of the time, and afforded it the highest imaginable satisfaction. (5) For the vanishing trust in the possibility of attaining the highest knowledge by the aid of reason it substituted the sure hope of a supernatural transformation of human nature which would even enable it to appropriate that which is above reason. (6) Lastly, it provided the traditional historical utterances respecting Christ, as well as the whole preceding course of history, with a firm foundation and a definite aim, and made it possible to conceive a history of salvation unfolding itself by degrees οικονομια Θεου. According to this conception the central point of history was no longer the Logos as such, but Christ as the incarnate God, while at the same time the moralistic interest was balanced by a really religious one. An approach was thus made to the Pauline theology, though indeed in a very peculiar way and to some extent only in appearance. A more exact representation of salvation through Christ has, however, been given by Irenæus as follows: Incorruptibility is a habitus which is the opposite of our present one and indeed of man's natural condition. For immortality is at once God's manner of existence and his attribute; as a created being man is only "capable of incorruption and immortality" ("capax incorruptionis et immortalitatis");[⁴⁹⁰] thanks to the divine goodness, however, he is intended for the same, and yet is empirically "subjected to the power of death" ("sub condicione mortis"). Now the sole way in which immortality as a physical condition can be obtained is by its possessor uniting himself realiter with human nature, in order to deify it "by adoption" ("per adoptionem"), such is the technical term of Irenæus. The deity must become what we are in order that we may become what he is. Accordingly, if Christ is to be the Redeemer, he must himself be God, and all the stress must fall upon his birth as man. "By his birth as man the eternal Word of God guarantees the inheritance of life to those who in their natural birth have inherited death."[⁴⁹¹] But this work of Christ can be conceived as recapitulatio because God the Redeemer is identical with God the Creator; and Christ consequently brings about a final condition which existed from the beginning in God's plan, but could not be immediately realised in consequence of the entrance of sin. It is perhaps Irenæus' highest merit, from a historical and ecclesiastical point of view, to have worked out this thought in pregnant fashion and with the simplest means, i.e., without the apparatus of the Gnostics, but rather by the aid of simple and essentially Biblical ideas. Moreover, a few decades later, he and Melito, an author unfortunately so little known to us, were already credited with this merit. For the author of the so-called "Little Labyrinth" (Euseb., H. E. V. 28. 5) can indeed boast with regard to the works of Justin, Miltiades, Tatian, Clement, etc., that they declared Christ to be God, but then continues: Τα Ειρηναιου τε και Μελιτωνος και των λοιπων τις αγνοει βιβλια, θεον και ανθρωπον καταγγελλοντα τον Χριστον ("Who is ignorant of the books of Irenæus, Melito, and the rest, which proclaim Christ to be God and man"). The progress in theological views is very precisely and appropriately expressed in these words. The Apologists also professed their belief in the full revelation of God upon earth, that is, in revelation as the teaching which necessarily leads to immortality;[⁴⁹²] but Irenæus is the first to whom Jesus Christ, God and man, is the centre of history and faith.[⁴⁹³] Following the method of Valentinus, he succeeded in sketching a history of salvation, the gradual realising of the οικονομια Θεου culminating in the deification of believing humanity, but here he always managed to keep his language essentially within the limits of the Biblical. The various acting æons of the Gnostics became to him different stages in the saving work of the one Creator and his Logos. His system seemed to have absorbed the rationalism of the Apologists and the intelligible simplicity of their moral theology, just as much as it did the Gnostic dualism with its particoloured mythology. Revelation had become history, the history of salvation; and dogmatics had in a certain fashion become a way of looking at history, the knowledge of God's ways of salvation that lead historically to an appointed goal.[⁴⁹⁴]

But, as this realistic, quasi-historical view of the subject was by no means completely worked out by Irenæus himself, since the theory of human freedom did not admit of its logical development, and since the New Testament also pointed in other directions, it did not yet become the predominating one even in the third century, nor was it consistently carried out by any one teacher. The two conceptions opposed to it, that of the early Christian eschatology and the rationalistic one, were still in vogue. The two latter were closely connected in the third century, especially in the West, whilst the mystic and realistic view was almost completely lacking there. In this respect Tertullian adopted but little from Irenæus. Hippolytus also lagged behind him. Teachers like Commodian, Arnobius, and Lactantius, however, wrote as if there had been no Gnostic movement at all, and as if no Antignostic Church theology existed. The immediate result of the work carried on by Irenæus and the Antignostic teachers in the Church consisted in the fixing of tradition and in the intelligent treatment of individual doctrines, which gradually became established. The most important will be set forth in what follows. On the most vital point, the introduction of the philosophical Christology into the Church's rule of faith, see Chapter 7.

The manner in which Irenæus undertook his great task of expounding and defending orthodox Christianity in opposition to the Gnostic form was already a prediction of the future. The oldest Christian motives and hopes; the letter of both Testaments, including even Pauline thoughts; moralistic and philosophical elements, the result of the Apologists' labours; and realistic and mystical features balance each other in his treatment. He glides over from the one to the other; limits the one by the other; plays off Scripture against reason, tradition against the obscurity of the Scriptures; and combats fantastic speculation by an appeal sometimes to reason, sometimes to the limits of human knowledge. Behind all this and dominating everything, we find his firm belief in the bestowal of divine incorruptibility on believers through the work of the God-man. This eclectic method did not arise from shrewd calculation. It was equally the result of a rare capacity for appropriating the feelings and ideas of others, combined with the conservative instincts that guided the great teacher, and the consequence of a happy blindness to the gulf which lay between the Christian tradition and the world of ideas prevailing at that time. Still unconscious of the greatest problem, Irenæus with inward sincerity sketched out that future dogmatic method according to which the theology compiled by an eclectic process is to be nothing else than the simple faith itself, this being merely illustrated and explained, developed and by that very process established, as far as "stands in the Holy Scripture," and—let us add—as far as reason requires. But Irenæus was already obliged to decline answering the question as to how far unexplained faith can be sufficient for most Christians, though nothing but this explanation can solve the great problems, "why more covenants than one were given to mankind, what was the character of each covenant, why God shut up every man unto unbelief, why the Word became flesh and suffered, why the advent of the Son of God only took place in the last times etc." (I. 10. 3). The relation of faith and theological Gnosis was fixed by Irenæus to the effect that the latter is simply a continuation of the former.[⁴⁹⁵] At the same time, however, he did not clearly show how the collection of historical statements found in the confession can of itself guarantee a sufficient and tenable knowledge of Christianity. Here the speculative theories are as a matter of fact quite imbedded in the historical propositions of tradition. Will these obscurities remain when once the Church is forced to compete in its theological system with the whole philosophical science of the Greeks, or may it be expected that, instead of this system of eclecticism and compromise, a method will find acceptance which, distinguishing between faith and theology, will interpret in a new and speculative sense the whole complex of tradition? Irenæus' process has at least this one advantage over the other method: according to it everything can be reckoned part of the faith, providing it bears the stamp of truth, without the faith seeming to alter its nature. It is incorporated in the theology of facts which the faith here appears to be.[⁴⁹⁶] The latter, however, imperceptibly becomes a revealed system of doctrine and history; and though Irenæus himself always seeks to refer everything again to the "simple faith" (φιλη πιστις), and to believing simplicity, that is, to the belief in the Creator and the Son of God who became man, yet it was not in his power to stop the development destined to transform the faith into knowledge of a theological system. The pronounced hellenising of the Gospel, brought about by the Gnostic systems, was averted by Irenæus and the later ecclesiastical teachers by preserving a great portion of the early Christian tradition, partly as regards its letter, partly as regards its spirit, and thus rescuing it for the future. But the price of this preservation was the adoption of a series of "Gnostic" formulæ. Churchmen, though with hesitation, adopted the adversary's way of looking at things, and necessarily did so, because as they became ever further and further removed from the early-Christian feelings and thoughts, they had always more and more lost every other point of view. The old Catholic Fathers permanently settled a great part of early tradition for Christendom, but at the same time promoted the gradual hellenising of Christianity.
