haud scio quid secutus: nam Eusebius et Tertullianus in hoc quod narro, consentiunt. Inter haec portenta latuerunt Potitus et Basiliscus, qui Marcionem secuti, duo rerum principia tradiderunt. Syrenus magis etiam delirans, tria principia, sive tres naturas induxit. Hos omnes secutus Tatianus, ex Justini discipulo factus haereticus, Valentini Marcionisque pestifera dogmata revocavit: discipulum habuit Calistionem. In tam longam seriem se porrexit illa detestanda lues a Simone Mago profecta, dictuque mirum quam aegre desiit. Jam enim Valentini nomen erat exstinctum, cum tamen non deessent Valentiniani. Nec omnino finis videbatur futurus, nisi venisset Montanus, qui caeteris omnibus abrogavit auctoritatem, se praedicans esse Spiritum sanctum a Christo promissum, qui deduceret in omnem veritatem. Quanquam et Manichaeus nonnihil erroris ex Basilide videtur hausisse. Accidit autem hic quod solet in febri vehementer tenaci, quae nunc est remissior, nunc acrior, nunc in aliam atque aliam speciem sese vertit, nec desinere potest, donec in phrenesim aut in aliud malum praesentius exeat. Adversus haec portenta scripsere Justinus, quem aliquoties citat Irenaeus, Miltiades, Proculus et Tertullianus: cujus libros quos eruditissimos scripsit adversus Valentinianos et Marcionem, praeterea de haeresibus et haereticorum praescriptis, si quis legere non gravabitur, rectius intelliget hos Irenaei libros.
I do not know what he followed: for Eusebius and Tertullian agree in what I relate. Among these monsters lurked Potitus and Basiliscus, who, following Marcion, taught two first principles of things. Syrenus, raving still more, brought in three principles, or three natures. Following all these, Tatian, made a heretic from a disciple of Justin, revived the pestilent dogmas of Valentinus and Marcion: he had Calistio as his disciple. To so long a series did that detestable plague, which set out from Simon Magus, stretch itself, and it is wonderful to say how hardly it ceased. For the name of Valentinus was already extinct, although Valentinians were still not lacking. Nor did there seem likely to be any end at all, had not Montanus come, who abrogated the authority of all the others, proclaiming himself to be the Holy Spirit promised by Christ, who should lead into all truth. Though Manichaeus too seems to have drawn something of error from Basilides. And here there happened what is wont to happen in a very tenacious fever, which is now milder, now sharper, now turns itself into one form and then another, and cannot cease until it issues in frenzy or in some other more immediate ill. Against these monsters wrote Justin, whom Irenaeus cites several times, Miltiades, Proculus and Tertullian: if anyone will not be loath to read the most learned books which he wrote against the Valentinians and Marcion, and besides on heresies and on the prescriptions of heretics, he will understand these books of Irenaeus more rightly.
Jam mihi videor satis praefatus, ornatissime praesul, quod ad hujus operis rationem attinet, et tempus erat finem imponere prologo: quod quidem faciam, si paucis aperuero, quae cogitatio subierit animum meum in hoc argumento versantis. Non enim queo satis admirari consilium inscrutabile Dei, qui miris modis sponsam suam Ecclesiam vindicarit, purgarit, erudierit, evexerit, illustrarit, in quibus omnibus nihil est non alienissimum ab humanis consiliis, quemadmodum ipse loquitur per Isaiam hominibus: Non enim cogitationes meae, cogitationes vestrae: neque viae meae, viae vestrae, dicit Dominus. Quia sicut exaltantur coeli a terra, sic exaltatae sunt viae meae a viis vestris, et cogitationes meae a cogitationibus vestris (Isa. LV, 8, 9). Quemadmodum igitur ipse Dominus descendens e coelis viam aperuit in coelos, et accepta forma servi paravit sibi dominium omnium quae in coelis, quaeque in terris, ac per summam ignominiam consecutus est aeternam gloriam, patiendo devicit hostem, morte promeruit immortalitatem: sic pusillum et imbellem gregem suum alienissimis a mundi ratione praesidiis provehit: per imperitos confutavit mundi sapientiam, per paucos subegit omnes mundi nationes, per imbecilles prostravit tyrannorum potentiam, per imbelles expugnavit omnem munitionem attollentem sese adversus Deum, per ignotos et humiles obscuravit universam mundi gloriam, per oves domuit leones, per columbos abegit serpentes. Et passus quidem est in oviculas suas Satanam et mundum hunc totis artibus ac viribus suis insurgere; verum arcanis suis consiliis omnia mala vertit electis suis in bonum. Solus enim ille Rex regum novit et uti bonis, et abuti malis in suam gloriam et Ecclesiae salutem. Infremuit adversus paucos et humiles Christi discipulos Judaeorum zelus, Pharisaeorum supercilium, sacerdotum auctoritas, tum regum legibus et copiis armata potentia, magorum praestigiae, philosophorum eruditio, haereticorum seditio. Tot machinis Satanas oppugnabat ovile Christi. Sed Domino temperante conatus et actiones hominum, suppliciis ac mortibus crevit et invaluit Ecclesia; impiorum philosophorum oblatrationibus confirmata est evangelica philosophia; praestigiae magorum illustrarunt Christi divinam virtutem in discipulis operantem; schismaticorum molimina piorum concordiam arctius junxerunt, ac velut in phalangem redegerunt; haereticorum impia dogmata, ad scrutandum arcanas litteras compulerunt. Itaque factum est ut, dum Judaei zelo legis, sed non secundum scientiam, pugnant adversus Evangelium, certius cognoverimus antiquatas esse legis umbras, et illustrata est Evangelii gloria. Rursus dum persecutor ignominiis, cruciatibus ac mortibus conatur fidem in Christum exstinguere, fidem auxerit, charitatem accenderit, spem reddiderit firmiorem, et piorum tolerantiam dum exercet, illustrarit. Postremo dum haereticorum argutationibus agitatur, magis uti didicit armatura divinarum litterarum, et confirmata est impugnata veritas. Primus Ecclesiae congressus fuit cum Judaeis, quorum utinam non exstarent et hodie reliquiae! Hic strenuum propugnatorem evangelicae libertatis praestitit apostolus Paulus. Magiae principem Petrus dejecit. Secundus fuit cum philosophis et haereticis, qui fere philosophiae praesidiis bellabant adversus Evangelium. Horum impressiones, post apostolos, exceperunt viri doctrina facundiaque praecellentes. Nec ideo damnanda est philosophiae sobria cognitio, quod a philosophis fere natae sunt omnes haereses, cum per philosophos item oppressae sint. Valentinus philosophus oppugnaverat Ecclesiam, sed Justinus philosophus, et Irenaeus philosophus defendit. Marcion philosophus impetiit veritatem, sed Tertullianus philosophus confecit hostem. Celsus philosophus blasphemias evomuit in Christum, sed Origenes melior philosophus ex illius blasphemiis illustravit Christi gloriam. Libanius sophista defendit idololatriam, sed hoc facundior Chrysostomus asseruit verum Dei cultum. Idem fecit orator Symmachus quod Libanius, sed hunc confodit potentior orator Prudentius. Itaque bona quaedam spes habet animum meum, fore ut hanc Ecclesiae tempestatem Dominus inscrutabili suo consilio vertat in bonos exitus, excitetque nobis Irenaeos aliquot qui, compositis dissidiis, pacem orbi restituant. Hunc interim Irenaeum velut ominis fausti loco laeta fronte dignaberis accipere, praesul optime, tui nominis auspiciis in lucem prodeuntem. Id ut facerem non tam mihi persuasit singularis quidam, ac ut gratuitus, ita perpetuus animi in me tui favor, quam uno omnium ore praedicata morum tuorum integritas, cum admirabili prudentia parique humanitate conjuncta. Sed nulla laus episcopo dignior, quam quod ubique studes paci concordiaeque Christiani populi. Atque hae quidem in te virtutes hoc sunt admirabiliores, quod aetate florenti Nestorem quemdam, ut ita loquar, praestas tum illustrissimo principi Ferdinando, tum Ecclesiae Christi. Nec ignota, nec tuas dotes praedico, sed pro donis in te collatis, et Deo gratias agimus, et nobis gratulamur. Amplitudinem tuam nobis omnibus augeat is, a quo solo proficiscitur vera felicitas. Datum Basileae sexto Kalend. Septembris. Anno MDXXVI.
I now seem to myself to have said enough by way of preface, most distinguished prelate, so far as concerns the plan of this work, and it was time to put an end to the prologue: which indeed I shall do, once I have disclosed in a few words what thought came into my mind while I was occupied with this subject. For I cannot sufficiently marvel at the inscrutable counsel of God, Who in wondrous ways has vindicated, purged, instructed, exalted and made illustrious His bride the Church, in all of which there is nothing that is not most foreign to human counsels, as He Himself speaks to men through Isaiah: For My thoughts are not your thoughts, nor are My ways your ways, says the Lord. For as the heavens are exalted above the earth, so are My ways exalted above your ways, and My thoughts above your thoughts (Isa. 55:8–9). As therefore the Lord Himself, descending from the heavens, opened the way into the heavens, and, having taken the form of a servant, gained for Himself dominion over all things that are in the heavens and that are on earth, and through the utmost ignominy attained eternal glory, conquered the enemy by suffering, and merited immortality by death: so He advances His little and unwarlike flock by defences most foreign to the reckoning of the world: through the unlearned He refuted the wisdom of the world, through a few He subdued all the nations of the world, through the weak He overthrew the power of tyrants, through the unwarlike He stormed every fortification that raises itself against God, through the obscure and lowly He darkened all the glory of the world, through sheep He tamed lions, through doves He drove away serpents. And He did indeed allow Satan and this world to rise up against His little sheep with all their arts and strength; but by His secret counsels He turned all evils to good for His elect. For He alone, the King of kings, knows both how to use good things and how to turn evil things to account for His own glory and the salvation of the Church. Against the few and lowly disciples of Christ there raged the zeal of the Jews, the haughtiness of the Pharisees, the authority of the priests, then power armed with the laws and forces of kings, the illusions of magicians, the learning of philosophers, the sedition of heretics. With so many engines did Satan assail the sheepfold of Christ. But, the Lord governing the endeavours and actions of men, the Church grew and gained strength through punishments and deaths; by the barking of impious philosophers the evangelical philosophy was confirmed; the illusions of the magicians made illustrious the divine power of Christ working in His disciples; the efforts of schismatics bound the concord of the godly more closely, and as it were drew them up into a phalanx; the impious dogmas of heretics drove them to search the secret writings. And so it came about that, while the Jews, with zeal for the law, but not according to knowledge, fight against the Gospel, we have learnt more surely that the shadows of the law are made obsolete, and the glory of the Gospel has been made illustrious. Again, while the persecutor tries by ignominies, tortures and deaths to extinguish faith in Christ, he has increased faith, kindled charity, made hope firmer, and, while he exercises the endurance of the godly, has made it illustrious. Lastly, while [the Church] is harried by the subtleties of heretics, she has learnt to use the armour of the divine writings the more, and the truth, being assailed, has been confirmed. The first encounter of the Church was with the Jews, whose remnants would that they did not survive even today! Here the apostle Paul showed himself a vigorous champion of evangelical liberty. Peter cast down the prince of magic. The second was with the philosophers and heretics, who mostly made war against the Gospel with the defences of philosophy. Their assaults, after the apostles, were met by men excelling in learning and eloquence. Nor is the sober knowledge of philosophy to be condemned on this account, that nearly all heresies were born of philosophers, since through philosophers likewise they have been crushed. Valentinus the philosopher had attacked the Church, but Justin the philosopher, and Irenaeus the philosopher, defended it. Marcion the philosopher assailed the truth, but Tertullian the philosopher finished off the enemy. Celsus the philosopher vomited blasphemies against Christ, but Origen, a better philosopher, made the glory of Christ illustrious out of his blasphemies. Libanius the sophist defended idolatry, but Chrysostom, more eloquent than he, upheld the true worship of God. Symmachus the orator did the same as Libanius, but Prudentius, a mightier orator, ran him through. And so a certain good hope holds my mind, that the Lord by His inscrutable counsel will turn this tempest of the Church to good outcomes, and will raise up for us some Irenaei, who, having settled the dissensions, may restore peace to the world. Meanwhile you will deign to receive this Irenaeus with a glad countenance, as by way of a good omen, best of prelates, as he comes forth into the light under the auspices of your name. To do this I was persuaded not so much by a singular favour of your mind towards me, as freely given as it is lasting, as by the integrity of your morals, proclaimed by the one voice of all, joined with admirable prudence and equal humanity. But no praise is worthier of a bishop than that you everywhere devote yourself to the peace and concord of the Christian people. And these virtues in you are the more admirable in this, that in the flower of your age you show yourself a Nestor, so to speak, both to the most illustrious prince Ferdinand and to the Church of Christ. I proclaim neither things unknown nor your own endowments, but for the gifts conferred on you we both give thanks to God and congratulate ourselves. May He from Whom alone true felicity proceeds increase your eminence for us all. Given at Basle on the sixth day before the Kalends of September. In the year MDXXVI.
