These, then, were the two modes in which the Christian Faith pursued and attained its orderly increase; as a seed it grew to a plant in each city, and as a plant it ramified, or as Tertullian says, carried “the vine-layer of the faith”216 from city to city, from province to province. In the meantime the last disciples of the Apostles, those who from the especial veneration with which they were regarded as teachers of the Faith and “second links in the chain of tradition,” were termed Presbyters,217 had died out. S. Polycarp, at the time of his martyrdom in 167, was probably the sole remaining one, though his pupil S. Irenæus had known others. When the latter, upon the martyrdom of S. Pothinus in 177, is raised to the government of the See of Lyons, we may consider that no one survived in possession of that great personal authority which belonged to those who had themselves been taught by Apostles; and so at the third generation from the last of these the Church throughout the world stood without any such support, simply upon that basis of the tradition and teaching of the truth, and of the succession of rulers, on which the Apostles had placed it, to last for ever. Now in this position it had already, throughout the whole course of the second century, been violently assaulted by a family of heresies, which growing upon one root – a natural philosophy confusing the being of God with the world – burst forth into an astonishing variety of outward forms. Gnosticism completely altered and defaced Christian doctrine under each of the four great heads, the Being of God, the Person of Christ, the nature of man, the office and function of the Church. Into the Godhead it introduced a dualism, recognising with the absolute good an absolute evil represented by matter: it denied the reality of the Incarnation; it made the body a principle of evil in man's nature: but we will here limit ourselves to the characteristic and formal principle of the system from which it derived its name, to Gnosis as the means of acquiring divine truth. Now the Christian religion taught that revealed truth was to be attained by the individual through receiving, upon the ground of the divine veracity, those mysterious doctrines superior but not contrary to reason which it unfolded; and that the communication of such doctrines might continue unimpaired and unchanging, it taught that our Lord had established a never-failing authority charged with the execution of this office, and assisted by the perpetual presence of His Spirit with it to the end. But the Gnostics admitted only in the case of the imperfect or natural man that faith was the means for acquiring religious truth; to the spiritual, the proper gnostic, gnosis should take the place of faith: for to many a heathen, accustomed to unlimited philosophical speculation, the absolute subjection of the intellect to divine authority, required by the principle of faith, was repugnant. Now this Gnosis was in their mind not knowledge grounded upon faith, but either philosophic science, or a supposed intuition of truth, which was not only to replace faith, but the whole moral life, inasmuch as the completion and sanctification of man were to be wrought by it. And thus instead of an external authority the individual reason was set up as the highest standard of religious truth, the issue of which could only be rationalism in belief and sectarianism in practice.
This formal principle of Gnosticism when duly carried out would deny the idea of the Church, its divine institution, its properties and prerogatives. For the gnostic mode of attaining divine truth, as above stated, contains in it such a denial. Besides this, the gnostic doctrine that matter was the seat of evil, destroyed the belief that Christ had assumed a body: the gnostic doctrine that the supreme God could enter into no communion with man made their Æon Christ no member of human society, but a phantom which had enlightened the man Jesus, and then returned back to the “Light-realm.” Not being really the Son of God, he could have no Church which was his body: not really redeeming, for sin to the gnostic had only a physical, not a moral cause, he was but a teacher, and therefore had created no institution to convey grace; which, moreover, was superfluous, for whatever elements of good human nature had were derived from creation and not from redemption. Nor was such an universal institution wanted, since not all men but only the spiritual were capable of being drawn up to the Light-realm. The Gnostic therefore required neither hierarchy nor priesthood, since the soul of this system was the gnosis of the individual. For this a body enjoying infallibility through the assistance of the Holy Ghost was not needed. It was enough for enthusiasts and dreamers to pursue their speculations without any limit to free inquiry, save what themselves chose to impose as the interpretation of such scriptures as they acknowledged, or as the exhibition of a private tradition with which they held themselves to be favoured.
Lastly, the idea of Sacraments, as conveying grace under a covering of sense, would be superfluous to the gnostic, inasmuch as the spiritual elements in man belong to him by nature, and are not communicated by a Redeemer, and would be repulsive to him because matter is a product of the evil principle, and cannot be the channel of grace from out the Light-realm.218
My purpose here has only been to say just so much of Gnosticism as may show how the whole Christian truth was attacked by it, and especially the existence and functions of the Church.
And this may indeed be termed the first heresy in that it struck its roots right up into Apostolic times. Irenæus, Eusebius, and Epiphanius account Simon Magus to be its father, and the father of all heresy. As such it is not without significance that he encountered the first of the Apostles in Samaria, endeavouring to purchase from him the gifts of grace and miraculous power, and that he likewise afterwards encountered him at Rome. To this the first manifestation of Gnosticism succeed heretical doctrines concerning the Person of our Lord, which sprung out of Judaism; but no sooner are these overcome than Gnosticism in its later forms spreads from Syria and Alexandria over the whole empire, everywhere confronting the Church, seducing her members, and tempting especially speculative minds within her. A mixture itself of Platonic, Philonic, Pythagorean, and Parsic philosophy, affecting to gather the best out of all philosophies and religions, in which it exactly represented the eclectic spirit of its age, arraying itself in the most fantastic garb of imagination, but at the bottom no dubious product of the old heathen pantheism, it set itself to the work, while it assumed Christian names, of confusing and distracting Christian truth. From the beginning of the second century it was the great enemy which beset the Church. It may, then, well represent to us the principle of heresy itself, and as such let us consider on what principles it was met by the Church's teachers.
Now to form a correct notion of the danger to which the Christian people at this time was exposed, we must have before us that it was contained in several hundred communities, each of them forming a complete spiritual society and government. These had arisen under the pressure of such hostility on the part of the empire that it is only in the time of the last emperor during this period, Alexander Severus, that churches are known to have publicly existed at Rome.219 For a very long time all meetings of Christians and all celebration of their worship was secret. It is obvious what an absolute freedom of choice on the part of all those who became Christians this fact involved. Nor did that freedom cease when they had been initiated into the new religion. Their fidelity to the Christian faith was all through their subsequent life solicited by the danger in which as Christians they stood. Only a continuous freedom of choice on their part could maintain it. And not only did every temporal interest turn against it, but in the case at least of the more intellectual converts the activity of thought implied in their voluntary acceptance of a new belief served as a material on which the seductions of false teachers might afterwards act, unless it was controlled by an everliving faith, and penetrated by an active charity. The more these Christian communities multiplied, the more it was to be expected that some of them would yield to the assaults of false teachers. It is in just such a state of things that a great dogmatic treatise was written against Gnosticism by one who stood at only a single remove from the Apostle John, being the disciple of his disciple Polycarp. Irenæus, by birth a native of lesser Asia, enjoyed when young the instructions and intimate friendship of the bishop of Smyrna. In his old age he delighted to remember how Polycarp had described his intercourse with John, and with those who had seen the Lord: how he repeated their discourse, and what he had heard from them respecting the teaching and the miracles of that Word of life whom they had seen with their own eyes. “These things,” says Irenæus, “through the mercy of God I then diligently listened to, writing them down not on paper, but on my heart, and by His grace I ruminate upon them perpetually.”220 Later in life he left Smyrna, and settled in Lyons, of which Church he was a presbyter when the terrible persecution of 177 broke out there. Elected thereupon to succeed a martyr as bishop, he crowned an episcopate of twenty-five years with a similar martyrdom. He wrote, as he says, during the episcopate of Eleutherius, who was the twelfth bishop of Rome from Peter, and sat from 177 to 192. After describing at length the Gnostic errors concerning the divine nature, he sets forth in contrast the unity of the truth as declared by the Church in the following words:
“The Church, though she be spread abroad through the whole world unto the ends of the earth, has received from the Apostles and their disciples faith in one God;” and he proceeds to recite her creed, in substance the same as that now held: then he adds, dwelling with emphasis on the very point which I have been noting, the sprinkling about, that is, of distinct communities so widely dispersed, which yet are one in their belief.
“This proclamation and this faith the Church having received, though she be disseminated through the whole world, carefully guards, as the inhabitant of one house, and equally believes these things as having one soul and the same heart, and in exact agreement these things she proclaims and teaches and hands down, as having one mouth. For, though the languages through the world be dissimilar, the power of the tradition is one and the same. Nor have the churches founded in Germany otherwise believed or otherwise handed down, nor those in Spain, nor in Gaul, nor in the East, nor in Egypt, nor those in the middle of the world. But as the sun, God's creature, in all the world is one and the same, so too the proclamation of the truth shines everywhere, and lights all men that are willing to come to the knowledge of the truth. Nor will he among the Church's rulers who is most powerful in word say other than this, for no one is above his teacher;221 nor will he that is weak in word diminish the tradition, for the Faith being one and the same, neither he that can say much on it has gathered too much, nor he that can say little is deficient.”
Against the gnostic claim to possess a private tradition, in virtue of which each of them “depraving the rule of the truth was not ashamed to preach himself,” he sets forth the one original tradition which the Apostles,222 only “when they had first been invested with the power of the Holy Ghost coming down on them, and endued with perfect knowledge,” delivered to the churches founded by them. “And this tradition of the Apostles, manifested in the whole world, may be seen in every church by all who have the will to see what is true, and we can give the chain of those who by the Apostles were appointed bishops in the churches, and their successors down to our time, who have neither taught nor known any such delirious dream as these imagine. For, had the Apostles known any reserved mysteries, which they taught to the perfect separately and secretly from the rest, assuredly they would have delivered them to those especially to whom they intrusted the churches themselves. For very perfect and irreprehensible in all respects did they wish those to be whom they left for their own successors,223 delivering over to them their own office of teaching, by correct conduct on whose part great advantage would accrue, as from their fall the utmost calamity. But since it were very long, in a volume like this, to enumerate the succession of all the churches, we take the church the greatest, the most ancient, and known to all, founded and established at Rome by the two most glorious Apostles Peter and Paul, and pointing out the tradition which it has received from the Apostles, and the faith which it has announced to men, reaching down to us by the succession of its bishops, we confound all those who form societies other than they ought, in any way, whether for the sake of self-fancied doctrines, or through blindness and an evil mind. For, with this church, on account of its superior principate, it is necessary that every church agree, that is, the faithful everywhere (every church) in which by the (faithful) everywhere, the apostolic tradition is preserved.
“The blessed Apostles, then, having founded and built up the church, committed to Linus the administration of its episcopate… Anencletus succeeds him, from whom in the third place from the Apostles Clemens inherits the episcopate… He is succeeded by Evaristus; Evaristus by Alexander, who is followed by Xystus sixth from the Apostles. Then Telesphorus, who was gloriously martyred; next Hyginus; then Pius; after whom Anicetus. Soter followed Anicetus; and now in the twelfth degree from the Apostles Eleutherius holds the place of bishop. By this order and succession the tradition from the Apostles in the Church and the teaching of the truth have come down to us. And this proof is most complete that it is one and the same life-giving Faith which has been preserved in the Church from the Apostles up to this time, and handed down in truth… With such proofs, then, before us, we ought not still to search among others for the truth, which it is easy to take from the Church, since the Apostles most fully committed unto this, as unto a rich storehouse, all which is of the truth, so that everyone, whoever will, may draw from it the draught of life. For this is the gate of life: all the rest are thieves and robbers. They must therefore be avoided; but whatever is of the Church we must love with the utmost diligence, and lay hold of the tradition of the truth. For how? if on any small matter question arose, ought we not to recur to the most ancient churches in which the Apostles lived, and take from them on the matter in hand what is certain and plain. And suppose the Apostles had not even left us writings, ought we not to follow that order of tradition which they delivered to those to whom they intrusted the churches? To this order many barbarous nations of believers in Christ assent, having salvation written upon their hearts by the Holy Spirit without paper and ink, and diligently guarding the old tradition.”224
This capital point of the ever-living teaching office he further dwells on:
“The Faith received in the Church we guard in it, which being always from the Spirit of God, like an admirable deposit in a good vessel, is young itself, and makes young the vessel in which it is. For this office on the part of God225 is intrusted to the Church, as the breath of life was given to the body, in order that all the members receiving may be quickened, and in this is placed the communication of Christ, that is, the Holy Spirit, the earnest of incorruption, the confirmation of our faith, and the ladder by which we ascend to God. For, says he, in the Church God has placed Apostles, Prophets, Teachers, and all the remaining operation of the Spirit; of whom all those are not partakers who do not run to the Church, but deprive themselves of life by an evil opinion and a still worse conduct. For where the Church is, there also is the Spirit of God: and where the Spirit of God is, there is the Church and all grace: but the Spirit is Truth. Wherefore they who are not partakers of Him are neither nourished unto life from the breasts of the mother, nor receive that most pure fountain which proceeds from the Body of Christ, but dig out for themselves broken cisterns from earthly ditches, and from the filth drink foul water, avoiding the Faith of the Church lest they be brought back, and rejecting the Spirit that they may not be taught. So estranged from the truth they deservedly wallow in every error, tossed about by it, having different opinions on the same subjects at different times, and never holding one firm mind, choosing rather to be sophists of words than disciples of the truth; for they are not founded upon the one rock, but on the sand, which has in it a multitude of pebbles.”226
And he elsewhere contrasts the certainty within, and the uncertainty without, this teaching power:
“The said heretics, then, being blind to the truth, cannot help walking out of the track into one path after another, and hence it is that the vestiges of their doctrine are scattered about without any rule or sequence. Whereas the road of those who are of the Church goes round the whole world, because it possesses a firm tradition from the Apostles, and gives us to see that all have one and the same faith, where all enjoin one and the same God the Father, believe one disposition of the Son of God's incarnation, know the same gift of the Spirit, meditate on the same precepts, guard the same regimen of ecclesiastical rule, await the same advent of the Lord, and support the same salvation of the whole man, body and soul alike. Now the Church's preaching is true and firm, in whom one and the same way of salvation is shown through the whole world. For to her is intrusted the light of God; and hence the wisdom of God, by which He saves all men, ‘is sung at her entrance, acts with confidence in her streets, is proclaimed on her walls, and speaks ever in the gates of the city.’ For everywhere the Church proclaims the truth: she is the seven-branched candlestick bearing Christ's light.”227
It has been necessary to give at considerable length the very words of S. Irenæus, because they are stronger and more perspicuous than any summary of them can be, and because they exhibit a complete answer not to this particular heresy only, but to all heresy for ever. Such an answer, coming from one who stood at the second generation from S. John, is of the highest value. Thus he meets the gnostic principle that divine truth is acquired by the individual through some process of his own mind, which in this particular case is termed gnosis, but which may bear many other names, by appealing to an external standard, the Rule of Faith in the Church from the beginning, which by its unity points to its origin and lineage from the apostles and Christ. And this serves to bring out the central idea which rules his whole mind, that “where the Church is, there also is the Spirit of God; and where the Spirit of God is, there is the Church and all grace: but the Spirit is Truth.” The deposit of which he spoke is not a dead mass, or lump of ore, requiring only safe custody, but a living Spirit dwelling in the Church, the source within her of unity, truth, and grace, using her teaching office, which is set up in her episcopate, for the drawing out and propagation of the deposit from the double fountain of Tradition and Scripture, for these her teachers as such have a divine gift of truth.228 It is thus that he expands without altering the doctrine of his teacher Polycarp's fellow-disciple, “Where Jesus Christ is, there is the Catholic Church.”229 And from it he proceeds to what follows necessarily on such a conception, that this Church must have a visible point of unity. As then he appeals to the churches founded by Apostles as the principal centres of living tradition, so before yet one of these churches had fallen into possession of heretics,230 before yet there was any disagreement between them, he singles out one for its superior principate, on account of which it was necessary for every church to agree with it, which he grounds on its descent from S. Peter and S. Paul, giving every link in the chain of succession during the hundred and ten years which had elapsed between their martyrdom and his own episcopate. He sees an especial prerogative lodged in that church as the means of securing the whole Church's organic unity; and this prerogative is, that it is among churches what S. Peter and S. Paul were among Apostles;231 as the first general western council expressed it, “in it the Apostles sit daily, and their blood without intermission bears witness to the glory of God.”232
Thus the conception expressed by Irenæus, with the greatest emphasis and continual repetition, in order to refute heresy, is that all truth and grace are stored up in the one body of the Church; to which his doctrine of the Roman Primacy is as the keystone to the arch. For everything in his view depends on the unity, the intrinsic harmony, of the truth which he is describing as lodged in the episcopate: the means therefore of securing that unity are part of its conception. Accordingly, to see in its due force his statement that every church must agree with the Roman Church, it must not be severed from the context and taken by itself, but viewed in connexion with the argument as part of which it stands. If the Church is to speak one truth with one mouth, which is his main idea, she must have an organic provision for such a result, which he places in the necessary agreement of all churches with one: and this is his second idea, subsidiary to the first, and completing it.
Irenæus by birth and education represents in all this the witness of the Asiatic churches; as bishop of Lyons, the churches of Gaul.
A few years after Irenæus, Tertullian in a professed treatise against heresy lays down exactly the same principles. With him, too, the main idea is the possession of all truth and grace by the one Body which Christ formed and the Apostles established. This he thus exhibits:
“We must not appeal to the Scriptures, nor try the issue on points on which the victory is either none, or doubtful, or too little doubtful. For though the debate on the Scriptures should not so turn out as to place each party on an equal footing, the order of things requires that that question should be first proposed which is the only one now to be discussed, To whom does the Faith itself belong? Whose are the Scriptures? From whom and through whom, when and to whom, was that discipline by which men become Christians delivered? For wherever the truth of that which is the Christian discipline at once and faith be shown to be, there will be the truth of the Scriptures, of their exposition, and of all Christian traditions. Our Lord Jesus Christ (may He suffer me so to speak for the present), whoever He is, of whatever God the Son, of whatever substance God and Man, of whatever reward the promiser, Himself declared so long as He was on earth, whether to the people openly, or to the disciples apart, what He was, what He had been, what will of the Father He administered, what duty of man He laid down. Of whom He had attached to his own side twelve in chief, the destined teachers of the nations. One of these having fallen off from Him, He bade the other eleven, on his departure to the Father after the resurrection, go and teach the nations, who were to be baptised into the Father, into the Son, and into the Holy Ghost. The Apostles then forthwith, the meaning of their title being the Sent, assuming by lot Matthias as a twelfth into the place of Judas, by the authority of the prophecy in the psalm of David, when they had obtained the promised power of the Holy Ghost for miracles and utterance, first through Judea bore witness to the Faith in Christ Jesus, and established churches, thence proceeding into the world promulgated the same doctrine of the same Faith to the nations, and thereupon founded churches in every city, from which the other churches thenceforth borrowed the vine-layer of the Faith and the seeds of the doctrine, and are daily borrowing them that they may become churches. And for this cause they are themselves also counted apostolical, as being the offspring of apostolical churches. The whole kind must be classed under its original. And thus these churches so many and so great are that one first from the Apostles, whence they all spring. Thus all are the first, and all apostolical, while all being the one prove unity: whilst there is between them communication of peace, and the title of brotherhood, and the token of hospitality.233 And no other principle rules these rights than the one tradition of the same sacrament.”234
Here is the summing up of what Irenæus had said with the force, brevity, and incisiveness which characterise Tertullian. Further on he rejects any appeal on the part of heretics to scripture:
“If the truth be in our possession, as many as walk by the rule which the Church has handed down from the Apostles, the Apostles from Christ, and Christ from God, the reasonableness of our proposition is manifest, which lays down that heretics are not to be allowed to enter an appeal to scriptures, since without scriptures we prove them to have no concern with scriptures. For if they are heretics, they cannot be Christians, inasmuch as they do not hold from Christ what they follow by their own choice, and in consequence admit the name of heretics.235 Therefore not being Christians, they have no right to Christian writings. To whom we may well say, Who are you? when did you come? and whence? What are you, who are not mine, doing in my property? By what right dost thou, Marcion, cut down my wood? By what license dost thou, Valentinus, turn the course of my waters? By what power remove my landmarks? This is my possession: how are you sowing it and feeding on it at your pleasure? It is mine, I repeat: I had it of old; I had it first: I have the unquestioned title-deeds from the first proprietors. I am the heir of the Apostles. According to their will, according to their trust, according to the oath I took from them, I hold it. You, assuredly, they have ever disinherited and renounced, as aliens, as enemies. But why are heretics aliens and enemies to Apostles, save from difference of doctrine, which each at his own pleasure has either brought forward or received against Apostles?”236
Thus Tertullian adds the witness of the African church to that of the Asiatic and Gallic churches in Irenæus.
We have noted the great church of Alexandria as a most complete instance of the growth whereby from the mother see the hierarchy took possession of a land. But the principle of such growth was the ecclesiastical rule, and its strength the energy with which that rule was preserved. This rule was twofold: the rule of discipline, or outward regimen, what we now call a constitution; and the rule of Faith. What the church of Alexandria was in discipline has been seen above: and now just at this time we have in the first great teacher of this church, who has come down to us, the most decisive exhibition of this rule as a defence against this same gnostic heresy. “As,” says Clement, “a man like those under the enchantment of Circe should become a beast, so whoever has kicked against the tradition of the Church, and started aside into the opinions of human heresies, has ceased to be a man of God, and faithful to the Lord.” … “There are three states of the soul, ignorance, opinion, knowledge. Those who are in ignorance, are the Gentiles; those in knowledge, the true Church; those in opinion, the adherents of heresies.” … “We have learnt that bodily pleasure is one thing, which we give to the Gentiles; strife a second, which we adjudge to heresies; joy a third, which is the property of the Church.” Again, he speaks of those who “not using the divine words well, but perversely, neither enter themselves into the kingdom of heaven, nor suffer those whom they have deceived to attain the truth. They have not indeed the key to the entrance, but rather a false key, whereby they do not enter as we do through the Lord's tradition, drawing back the veil, but cutting out a side way, and secretly digging through the Church's wall, they transgress the truth, and initiate into rites of error the soul of the irreligious. For that they have made their human associations later than the Catholic Church, it needs not many words to show.” Then, after referring to the origin and propagation “of the Lord's teaching,”237 exactly after the mode of Irenæus and Tertullian, he concludes, “So it is clear from the most ancient and true Church, that these heresies coming in subsequently to it, and others still later, are innovations from it, as coins of adulterate stamp. From what has been said, then, I consider it manifest that the true Church, the really ancient Church, is one, in which are enrolled all who are just according to (God's) purpose. For inasmuch as there is one God and one Lord, therefore that which is most highly precious is praised for being alone, since it is an imitation of the one Principle. The one Church, then, which they try by force to cut up into many heresies, falls under the same category as the nature of the One. So then we assert that the ancient and Catholic Church is one alone in its foundation, in its idea, in its origin, and in its excellence, collecting by the will of the one God, through the one Lord, into the unity of one Faith, according to the peculiar covenants, or rather to the one covenant at different times, the preordained whom God predestined, having known before the foundation of the world that they would be just. But the excellence of the Church, as the principle of the whole construction, is in unity, surpassing all other things, and having nothing similar or equal to itself.”238
