BOOK 3 PREFACE
Thou hast indeed enjoined upon me, my very dear friend, that I should bring to light the Valentinian doctrines, concealed, as their votaries imagine; that I should exhibit their diversity, and compose a treatise in refutation of them. I therefore have undertaken–showing that they spring from Simon, the father of all heretics–to exhibit both their doctrines and successions, and to set forth arguments against them all. Wherefore, since the conviction of these men and their exposure is in many points but one work, I have sent unto thee [certain] books, of which the first comprises the opinions of all these men, and exhibits their customs, and the character of their behaviour. In the second, again, their perverse teachings are cast down and overthrown, and, such as they really are, laid bare and open to view. But in this, the third book I shall adduce proofs from the Scriptures, so that I may come behind in nothing of what thou hast enjoined; yea, that over and above what thou didst reckon upon, thou mayest receive from me the means of combating and vanquishing those who, in whatever manner, are propagating falsehood. For the love of God, being rich and ungrudging, confers upon the suppliant more than he can ask from it. Call to mind then, the things which I have stated in the two preceding books, and, taking these in connection with them, thou shalt have from me a very copious refutation of all the heretics; and faithfully and strenuously shalt thou resist them in defence of the only true and life-giving faith, which the Church has received from the apostles and imparted to her sons. For the Lord of all gave to His apostles the power of the Gospel, through whom also we have known the truth, that is, the doctrine of the Son of God; to whom also did the Lord declare: “He that heareth you, heareth Me; and he that despiseth you, despiseth Me, and Him that sent Me.” 
The apostles did not commence to preach the Gospel, or to place anything on record until they were endowed with the gifts and power of the Holy Spirit. They preached one God alone, Maker of heaven and earth.
1. We have learned from none others the plan of our salvation, than from those through whom the Gospel has come down to us, which they did at one time proclaim in public, and, at a later period, by the will of God, handed down to us in the Scriptures, to be the ground and pillar of our faith.  For it is unlawful to assert that they preached before they possessed “perfect knowledge,” as some do even venture to say, boasting themselves as improvers of the apostles. For, after our Lord rose from the dead, [the apostles] were invested with power from on high when the Holy Spirit came down [upon them], were filled from all [His gifts], and had perfect knowledge: they departed to the ends of the earth, preaching the glad tidings of the good things [sent] from God to us, and proclaiming the peace of heaven to men, who indeed do all equally and individually possess the Gospel of God. Matthew also issued a written Gospel among the Hebrews  in their own dialect, while Peter and Paul were preaching at Rome, and laying the foundations of the Church. After their departure, Mark, the disciple and interpreter of Peter, did also hand down to us in writing what had been preached by Peter. Luke also, the companion of Paul, recorded in a book the Gospel preached by him. Afterwards, John, the disciple of the Lord, who also had leaned upon His breast, did himself publish a Gospel during his residence at Ephesus in Asia. 2. These have all declared to us that there is one God, Creator of heaven and earth, announced by the law and the prophets; and one Christ the Son of God. If any one do not agree to these truths, he despises the companions of the Lord; nay more, he despises Christ Himself the Lord; yea, he despises the Father also, and stands self-condemned, resisting and opposing his own salvation, as is the case with all heretics.
The heretics follow neither Scripture nor tradition.
1. When, however, they are confuted from the Scriptures, they turn round and accuse these same Scriptures, as if they were not correct, nor of authority, and [assert] that they are ambiguous, and that the truth cannot be extracted from them by those who are ignorant of tradition. For [they allege] that the truth was not delivered by means of written documents, but viva voce: wherefore also Paul declared, “But we speak wisdom among those that are perfect, but not the wisdom of this world.”  And this wisdom each one of them alleges to be the fiction of his own inventing, forsooth; so that, according to their idea, the truth properly resides at one time in Valentinus, at another in Marcion, at another in Cerinthus, then afterwards in Basilides, or has even been indifferently in any other opponent,  who could speak nothing pertaining to salvation. For every one of these men, being altogether of a perverse disposition, depraving the system of truth, is not ashamed to preach himself.
2. But, again, when we refer them to that tradition which originates from the apostles, [and] which is preserved by means of the succession of presbyters in the Churches, they object to tradition, saying that they themselves are wiser not merely than the presbyters, but even than the apostles, because they have discovered the unadulterated truth. For [they maintain] that the apostles intermingled the things of the law with the words of the Saviour; and that not the apostles alone, but even the Lord Himself, spoke as at one time from the Demiurge, at another from the intermediate place, and yet again from the Pleroma, but that they themselves, indubitably, unsulliedly, and purely, have knowledge of the hidden mystery: this is, indeed, to blaspheme their Creator after a most impudent manner! It comes to this, therefore, that these men do now consent neither to Scripture nor to tradition.
3. Such are the adversaries with whom we have to deal, my very dear friend, endeavouring like slippery serpents to escape at all points. Wherefore they must be opposed at all points, if perchance, by cutting off their retreat, we may succeed in turning them back to the truth. For, though it is not an easy thing for a soul under the influence of error to repent, yet, on the other hand, it is not altogether impossible to escape from error when the truth is brought alongside it.
A refutation of the heretics, from the fact that, in the various Churches, a perpetual succession of bishops was kept up.
1. It is within the power of all, therefore, in every Church, who may wish to see the truth, to contemplate clearly the tradition of the apostles manifested throughout the whole world; and we are in a position to reckon up those who were by the apostles instituted bishops in the Churches, and [to demonstrate] the succession of these men to our own times; those who neither taught nor knew of anything like what these [heretics] rave about. For if the apostles had known hidden mysteries, which they were in the habit of imparting to “the perfect” apart and privily from the rest, they would have delivered them especially to those to whom they were also committing the Churches themselves. For they were desirous that these men should be very perfect and blameless in all things, whom also they were leaving behind as their successors, delivering up their own place of government to these men; which men, if they discharged their functions honestly, would be a great boon [to the Church], but if they should fall away, the direst calamity.
2. Since, however, it would be very tedious, in such a volume as this, to reckon up the successions of all the Churches, we do put to confusion all those who, in whatever manner, whether by an evil self-pleasing, by vainglory, or by blindness and perverse opinion, assemble in unauthorized meetings; [we do this, I say,] by indicating that tradition derived from the apostles, of the very great, the very ancient, and universally known Church founded and organized at Rome by the two most glorious apostles, Peter and Paul; as also [by pointing out] the faith preached to men, which comes down to our time by means of the successions of the bishops. For it is a matter of necessity that every Church should agree with this Church, on account of its pre-eminent authority,  that is, the faithful everywhere, inasmuch as the apostolical tradition has been preserved continuously by those [faithful men] who exist everywhere.
3. The blessed apostles, then, having founded and built up the Church, committed into the hands of Linus the office of the episcopate. Of this Linus, Paul makes mention in the Epistles to Timothy. To him succeeded Anacletus; and after him, in the third place from the apostles, Clement was allotted the bishopric. This man, as he had seen the blessed apostles, and had been conversant with them, might be said to have the preaching of the apostles still echoing [in his ears], and their traditions before his eyes. Nor was he alone [in this], for there were many still remaining who had received instructions from the apostles. In the time of this Clement, no small dissension having occurred among the brethren at Corinth, the Church in Rome despatched a most powerful letter to the Corinthians, exhorting them to peace, renewing their faith, and declaring the tradition which it had lately received from the apostles, proclaiming the one God, omnipotent, the Maker of heaven and earth, the Creator of man, who brought on the deluge, and called Abraham, who led the people from the land of Egypt, spake with Moses, set forth the law, sent the prophets, and who has prepared fire for the devil and his angels. From this document, whosoever chooses to do so, may learn that He, the Father of our Lord Jesus Christ, was preached by the Churches, and may also understand the apostolical tradition of the Church, since this Epistle is of older date than these men who are now propagating falsehood, and who conjure into existence another god beyond the Creator and the Maker of all existing things. To this Clement there succeeded Evaristus. Alexander followed Evaristus; then, sixth from the apostles, Sixtus was appointed; after him, Telesphorus, who was gloriously martyred; then Hyginus; after him, Pius; then after him, Anicetus. Soter having succeeded Anicetus, Eleutherius does now, in the twelfth place from the apostles, hold the inheritance of the episcopate. In this order, and by this succession, the ecclesiastical tradition from the apostles, and the preaching of the truth, have come down to us. And this is most abundant proof that there is one and the same vivifying faith, which has been preserved in the Church from the apostles until now, and handed down in truth.
4. But Polycarp also was not only instructed by apostles, and conversed with many who had seen Christ, but was also, by apostles in Asia, appointed bishop of the Church in Smyrna, whom I also saw in my early youth, for he tarried [on earth] a very long time, and, when a very old man, gloriously and most nobly suffering martyrdom,  departed this life, having always taught the things which he had learned from the apostles, and which the Church has handed down, and which alone are true. To these things all the Asiatic Churches testify, as do also those men who have succeeded Polycarp down to the present time,–a man who was of much greater weight, and a more stedfast witness of truth, than Valentinus, and Marcion, and the rest of the heretics. He it was who, coming to Rome in the time of Anicetus caused many to turn away from the aforesaid heretics to the Church of God, proclaiming that he had received this one and sole truth from the apostles,–that, namely, which is handed down by the Church.  There are also those who heard from him that John, the disciple of the Lord, going to bathe at Ephesus, and perceiving Cerinthus within, rushed out of the bath-house without bathing, exclaiming, “Let us fly, lest even the bath-house fall down, because Cerinthus, the enemy of the truth, is within.” And Polycarp himself replied to Marcion, who met him on one occasion, and said, “Dost thou know me?” “I do know thee, the first-born of Satan.” Such was the horror which the apostles and their disciples had against holding even verbal communication with any corrupters of the truth; as Paul also says, “A man that is an heretic, after the first and second admonition, reject; knowing that he that is such is subverted, and sinneth, being condemned of himself.”  There is also a very powerful  Epistle of Polycarp written to the Philippians, from which those who choose to do so, and are anxious about their salvation, can learn the character of his faith, and the preaching of the truth. Then, again, the Church in Ephesus, founded by Paul, and having John remaining among them permanently until the times of Trajan, is a true witness of the tradition of the apostles.
The truth is to be found nowhere else but in the Catholic Church, the sole depository of apostolical doctrine. Heresies are of recent formation, and cannot trace their origin up to the apostles.
1. Since therefore we have such proofs, it is not necessary to seek the truth among others which it is easy to obtain from the Church; since the apostles, like a rich man [depositing his money] in a bank, lodged in her hands most copiously all things pertaining to the truth: so that every man, whosoever will, can draw from her the water of life.  For she is the entrance to life; all others are thieves and robbers. On this account are we bound to avoid them, but to make choice of the thing pertaining to the Church with the utmost diligence, and to lay hold of the tradition of the truth. For how stands the case? Suppose there arise a dispute relative to some important question  among us, should we not have recourse to the most ancient Churches with which the apostles held constant intercourse, and learn from them what is certain and clear in regard to the present question? For how should it be if the apostles themselves had not left us writings? Would it not be necessary, [in that case,] to follow the course of the tradition which they handed down to those to whom they did commit the Churches?
2. To which course many nations of those barbarians who believe in Christ do assent, having salvation written in their hearts by the Spirit, without paper or ink, and, carefully preserving the ancient tradition,  believing in one God, the Creator of heaven and earth, and all things therein, by means of Christ Jesus, the Son of God; who, because of His surpassing love towards His creation, condescended to be born of the virgin, He Himself uniting man through Himself to God, and having suffered under Pontius Pilate, and rising again, and having been received up in splendour, shall come in glory, the Saviour of those who are saved, and the Judge of those who are judged, and sending into eternal fire those who transform the truth, and despise His Father and His advent. Those who, in the absence of written documents,  have believed this faith, are barbarians, so far as regards our language; but as regards doctrine, manner, and tenor of life, they are, because of faith, very wise indeed; and they do please God, ordering their conversation in all righteousness, chastity, and wisdom. If any one were to preach to these men the inventions of the heretics, speaking to them in their own language, they would at once stop their ears, and flee as far off as possible, not enduring even to listen to the blasphemous address. Thus, by means of that ancient tradition of the apostles, they do not suffer their mind to conceive anything of the [doctrines suggested by the] portentous language of these teachers, among whom neither Church nor doctrine has ever been established.
3. For, prior to Valentinus, those who follow Valentinus had no existence; nor did those from Marcion exist before Marcion; nor, in short, had any of those malignant-minded people, whom I have above enumerated, any being previous to the initiators and inventors of their perversity. For Valentinus came to Rome in the time of Hyginus, flourished under Pius, and remained until Anicetus. Cerdon, too, Marcion’s predecessor, himself arrived in the time of Hyginus, who was the ninth bishop.  Coming frequently into the Church, and making public confession, he thus remained, one time teaching in secret, and then again making public confession; but at last, having been denounced for corrupt teaching, he was excommunicated  from the assembly of the brethren. Marcion, then, succeeding him, flourished under Anicetus, who held the tenth place of the episcopate. But the rest, who are called Gnostics, take rise from Menander, Simon’s disciple, as I have shown; and each one of them appeared to be both the father and the high priest of that doctrine into which he has been initiated. But all these (the Marcosians) broke out into their apostasy much later, even during the intermediate period of the Church.
Christ and His apostles, without any fraud, deception, or hypocrisy, preached that one God, the Father, was the founder of all things. They did not accommodate their doctrine to the prepossessions of their hearers.
1. Since, therefore, the tradition from the apostles does thus exist in the Church, and is permanent among us, let us revert to the Scriptural proof furnished by those apostles who did also write the Gospel, in which they recorded the doctrine regarding God, pointing out that our Lord Jesus Christ is the truth,  and that no lie is in Him. As also David says, prophesying His birth from a virgin, and the resurrection from the dead, “Truth has sprung out of the earth.”  The apostles, likewise, being disciples of the truth, are above all falsehood; for a lie has no fellowship with the truth, just as darkness has none with light, but the presence of the one shuts out that of the other. Our Lord, therefore, being the truth, did not speak lies; and whom He knew to have taken origin from a defect, He never would have acknowledged as God, even the God of all, the Supreme King, too, and His own Father, an imperfect being as a perfect one, an animal one as a spiritual, Him who was without the Pleroma as Him who was within it. Neither did His disciples make mention of any other God, or term any other Lord, except Him, who was truly the God and Lord of all, as these most vain sophists affirm that the apostles did with hypocrisy frame their doctrine according to the capacity of their hearers, and gave answers after the opinions of their questioners,–fabling blind things for the blind, according to their blindness; for the dull according to their dulness; for those in error according to their error. And to those who imagined that the Demiurge alone was God, they preached him; but to those who are capable of comprehending the unnameable Father, they did declare the unspeakable mystery through parables and enigmas: so that the Lord and the apostles exercised the office of teacher not to further the cause of truth, but even in hypocrisy, and as each individual was able to receive it!
2. Such [a line of conduct] belongs not to those who heal, or who give life: it is rather that of those bringing on diseases, and increasing ignorance; and much more true than these men shall the law be found, which pronounces every one accursed who sends the blind man astray in the way. For the apostles, who were commissioned to find out the wanderers, and to be for sight to those who saw not, and medicine to the weak, certainly did not address them in accordance with their opinion at the time, but according to revealed truth. For no persons of any kind would act properly, if they should advise blind men, just about to fall over a precipice, to continue their most dangerous path, as if it were the right one, and as if they might go on in safety. Or what medical man, anxious to heal a sick person, would prescribe in accordance with the patient’s whims, and not according to the requisite medicine? But that the Lord came as the physician of the sick, He does Himself declare saying, “They that are whole need not a physician, but they that are sick; I came not to call the righteous, but sinners to repentance.”  How then shall the sick be strengthened, or how shall sinners come to repentance? Is it by persevering in the very same courses? or, on the contrary, is it by undergoing a great change and reversal of their former mode of living, by which they have brought upon themselves no slight amount of sickness, and many sins? But ignorance, the mother of all these, is driven out by knowledge. Wherefore the Lord used to impart knowledge to His disciples, by which also it was His practice to heal those who were suffering, and to keep back sinners from sin. He therefore did not address them in accordance with their pristine notions, nor did He reply to them in harmony with the opinion of His questioners, but according to the doctrine leading to salvation, without hypocrisy or respect of person.
3. This is also made clear from the words of the Lord, who did truly reveal the Son of God to those of the circumcision– Him who had been foretold as Christ by the prophets; that is, He set Himself forth, who had restored liberty to men, and bestowed on them the inheritance of incorruption. And again, the apostles taught the Gentiles that they should leave vain stocks and stones, which they imagined to be gods, and worship the true God, who had created and made all the human family, and, by means of His creation, did nourish, increase, strengthen, and preserve them in being; and that they might look for His Son Jesus Christ, who redeemed us from apostasy with His own blood, so that we should also be a sanctified people,–who shall also descend from heaven in His Father’s power, and pass judgment upon all, and who shall freely give the good things of God to those who shall have kept His commandments. He, appearing in these last times, the chief cornerstone, has gathered into one, and united those that were far off and those that were near;  that is, the circumcision and the uncircumcision, enlarging Japhet, and placing him in the dwelling of Shem.
