The Episcopate of Irenæus was distinguished by labours, “in season and out of season,” for the evangelization of Southern Gaul; and he seems to have sent missionaries into other regions of what we now call France. In spite of Paganism and heresy, he rendered Lyons a Christian city; and Marcus seems to have retreated before his terrible castigation, taking himself off to regions beyond the Pyrenees.5 But the pacific name he bears, was rendered yet more illustrious by his interposition to compose the Easter Controversy, then threatening to impair, if not to destroy, the unity of the Church. The beautiful concordat between East and West, in which Polycarp and Anicetus had left the question, was now disturbed by Victor, Bishop of Rome, whose turbulent spirit would not accept the compromise of his predecessor. Irenæus remonstrates with him in a catholic spirit, and overrules his impetuous temper. At the Council of Nice, the rule for the observance of Easter was finally settled by the whole Church; and the forbearing example of Irenæus, no doubt contributed greatly to this happy result. The blessed peacemaker survived this great triumph, for a short time only, closing his life, like a true shepherd, with thousands of his flock, in the massacre (a.d. 202) stimulated by the wolfish Emperor Severus. The Introductory Notice of the learned translators6 is as follows:— 311 The work of Irenæus Against Heresies is one of the most precious remains of early Christian antiquity. It is devoted, on the one hand, to an account and refutation of those multiform Gnostic heresies which prevailed in the latter half of the second century; and, on the other hand, to an exposition and defence of the Catholic faith. In the prosecution of this plan, the author divides his work into five books. The first of these contains a minute description of the tenets of the various heretical sects, with occasional brief remarks in illustration of their absurdity, and in confirmation of the truth to which they were opposed. In his second book, Irenæus proceeds to a more complete demolition of those heresies which he has already explained, and argues at great length against them, on grounds principally of reason. The three remaining books set forth more directly the true doctrines of revelation, as being in utter antagonism to the views held by the Gnostic teachers. In the course of this argument, many passages of Scripture are quoted and com- mented on; many interesting statements are made, bearing on the rule of faith; and much 5 On the authority of St. Jerome. See Guettée, De l’église de France, vol. 1. p. 27. 6 The first two books of Irenæus Against Heresies have been translated by Dr. Roberts. The groundwork of the translation of the third book, and that portion of the fourth book which is continued in this volume, has been furnished by the Rev. W. H. Rambaut. An attempt has been made, in rendering this important author into English, to adhere as closely as possible to the original. It would have been far easier to give a loose and flowing translation of the obscure and involved sentences of Irenæus; but the object has been studiously kept in view, to place the English reader, as much as possible, in the position of one who has immediate access to the Greek or Latin text. 836 Introductory Note to Irenæus Against Heresies
