That Irenæus, writing about 175, could appeal to the episcopal succession as commonly recognized and admitted, and use it as a basis of unity for the Church, is generally regarded as evidence of the existence of a wide-spread episcopal organization at an early date in the second century. Possibly the connection of Irenæus with Asia Minor, where the episcopal organization admittedly was earliest, diminishes the force of the argument. The reference to the “charisma of truth,” which the bishops were said to possess, was to furnish later a theoretical basis for the authority of bishops assembled in council. Ch. 2. Wherefore it is incumbent to obey the presbyters who are in the Church, those who, as I have shown, possess the succession from the Apostles; those who together with the succession of the episcopate have received the certain gift [charisma] of the truth according to the good pleasure of the Father; but also to hold in suspicion others who depart from the primitive succession and assemble themselves together in any place whatsoever.… Ch. 5. Such presbyters does the Church nourish, of whom also the prophet says: “I will give thy rulers in peace, and thy bishops in righteousness” [_cf._ Is. 60:17]. Of whom also the Lord did declare: “Who, then, shall be a faithful steward, good and wise, whom the Lord sets over His household, to give them their meat in due season? Blessed is that servant whom his Lord when he cometh shall find so doing” [Matt. 24:45 _f._]. Paul, then, teaching us where one may find such, says: “God hath placed in the Church, first, Apostles; secondly, prophets; thirdly, teachers” [I Cor. 12:28]. Where, then, the gifts of the Lord have been placed there we are to learn the truth; namely, from those who possess the succession of the Church from the Apostles, and among whom exists that which is sound and blameless in conduct, as well as that which is unadulterated and incorrupt in speech. (_b_) Tertullian, _De Præscriptione_, 32. (MSL, 2:52.) In Tertullian’s statement as to the necessity of apostolic succession, the language is more precise than in Irenæus’s. Bishop and presbyter are not used as interchangeable terms, as would appear in the passage in Irenæus. The whole is given a more legal turn, as was in harmony with the writer’s legal mind.
