IRENAEUS OF LYONS

Dan Petty

Irenaeus (born ca. a.d. 120 or 140) was probably a native of Smyrna where Polycarp was bishop. Serving as bishop of Lyons from ca.177 until his death in ca. 202, Irenaeus spend much of his life dealing with the gnostic heresy. Of his two writings that still exist, the best known is Against Heresies (A Refutation and Subversion of Knowledge Falsely So Called), consisting of five books dealing with gnosticism.  Until the discovery of Gnostic texts at Nag Hammadi in 1946, most information about gnosticism came to us through Irenaeus’ writings.

 

            Most gnostics taught that the material world is inherently evil, having been created by a being (demiurge) that fell away from God; that Christ did not come in the flesh, nor experience a bodily resurrection; and that salvation is achieved through a special knowledge (gnosis) that frees the human spirit from the material body, and through strict denial of the flesh (asceticism). Many of them rejected the Old Testament and much of the New.   

 

            In responding to the Gnostics, Irenaeus emphasized the unity of the Old and New Testaments, as shown by fulfilled prophecy and by the parallelism between Adam and Christ. He saw the divine plan for the new covenant as a “recapitulation” of the original creation. Adam was created in the image and likeness of God. Sin resulted in the loss of the moral likeness, but not the divine image. Human beings were created free and responsible beings. The incarnation of Christ was not the result of sin, as the Gnostics said, but rather a remedy for sin. In Christ the divine Word assumed a humanity like Adam possessed before the fall. He became man so man could be made in the divine image. Salvation is a restoration of what was lost in Paradise. The purpose of history to Ireneaus is an on-going process by which God teaches, guides, and tutors man to a state of communion with God. Mankind is growing to maturity, but mistakes were made in man’s infancy. The fall was permitted as part of the discipline and growth process. This was Ireneaus’ answer to the gnostics’ preoccupation with evil in the world.

 

Apostolic Authority of Scripture

 

In responding to the Gnostics, Ireneaus also provided reasons for accepting the authority of the New Testament books. He believed the New Testament should be accepted because it rests on apostolic authority. “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. . . .” (Against Heresies 3). “We have learned from none others the plan of our salvation, than from those through whom the Gospel has come down to us [the apostles, dwp], 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” (Against Heresies 3.1.1). He acknowledged as authoritative those books that virtually correspond to the 27 books of the canon. He believed the Bible taken as a whole is self-evident and that we should interpret scripture in the light of scripture.

The Doctrine of Apostolic Succession

 

Irenaeus went beyond scripture, however, and taught that orthodoxy is also based ultimately on a succession of teachers, the bishops, in any church founded by an apostle. This is called the doctrine of apostolic succession. “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” (Against Heresies 3.3.1). Since the teachings of the gnostics are of recent origin and are not taught by the successors to the apostles, Irenaeus concluded, they must not be orthodox. Irenaeus went so far as to provide a list of bishops of the church at Rome, which he argued, proved an unbroken succession from Peter and Paul down to his own day. “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” (Against Heresies 3.3.3).

 

Authority of Church Tradition

 

Irenaeus also contributed to the concept that the tradition of the church, passed down from the apostles to their successors, is equally authoritative along with scripture. “For it is a matter of necessity that every Church should agree with this Church [Rome, dwp], on account of its preeminent authority, that is, the faithful everywhere, inasmuch as the apostolic tradition has been preserved continuously by those [faithful men] who exist everywhere” (Against Heresies 3.3.2). His argument was that the authority of the church in Rome rested on the uniformity of its tradition with the tradition of the church as a whole. This paved the way for the Roman Catholic doctrine that revealed truth does not come through scripture alone. “Both Scripture and Tradition must be accepted and honored with equal sentiments of devotion and reverence” (Catechism of the Catholic Church [1995 ed.], 31).

 

Early Development of Creeds

 

Irenaeus’ theory of apostolic succession also contributed to the development of creeds. These “summaries of Christian faith, known as Rules of Faith, became common in the second half of the second century. . . . They also provided theological material for defense against the heretics” (John Leith, ed., Creeds of the Churches 20). Ireneaus believed heresy and division could be avoided by retaining what he called the “rule of the truth” acknowledged by the churches (Against Heresies 1.9.4). He was one of the first to outline such a “rule of faith” (1.10.1), and taught that “the Church, having received this preaching and this faith . . . carefully preserves it” (1.10.2).

 

Growth of Church Hierarchy

 

It was only natural, given Irenaeus’ emphasis on the inherent authority of bishops as successors to the apostles, that efforts would soon be given to organizing the church on the universal level. Churches that were believed to be “apostolic churches,” whose bishops were direct apostolic successors, enjoyed greater status than others. Notice Irenaeus’ statements regarding the church at Rome: “. . . 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 succession of the bishops” (Against Heresies 3.3.2). The large city churches began to influence or take oversight of the smaller churches in the villages or countryside.

 

The New Testament Pattern

 

The New Testament shows how churches in the first century were organized and governed. Local churches were autonomous, each governed by a plurality of elders (Acts 14:23; Tit. 1:5). The church was never organized universally or beyond the local level. History’s lessons of efforts to centralize the church should not go unheeded. Missionary societies, human institutions or sponsoring churches violate the New Testament pattern as much as the hierarchy of the Catholic Church. But so does the tendency of papers, schools, elderships or preachers to wield undue pressure or influence upon the affairs of other churches.

 

Apostolic authority is found in the New Testament, not in any man. The apostles were uniquely called, appointed and sent out by the Lord (Mark 3:13f) and were eyewitnesses of His resurrection (Acts 1:15-26; 1 Cor. 9:1). Their powers were never passed down to others; but their teachings helped form the foundation of the church (Eph. 2:20) and have been passed down in the New Testament. We continue in the apostles’ teaching (Acts 2:42). The New Testament is thus all-sufficient as our guide in spiritual matters (Gal. 1:6-9; Eph. 3:3-5; 1 Thess. 2:13).
