Early Church Leaders: IRENAEUS OF LYONS

SHARE

 IRENAEUS OF LYONS

Irenaeus was a native of Asia Minor—probably Smyrna—where he was born around the year 130. There he was a disciple of Polycarp, of whose martyrdom we have already told in an earlier chapter. Throughout his life, Irenaeus was a fervent admirer of Polycarp, and in his writings he often speaks of an “old man”—or a presbyter—whose name is not given, but who is probably Polycarp.

In any case, unknown reasons led Irenaeus to migrate to Lyons, in what is today southern France. There he became a presbyter, and as such was sent to Rome with a message for the bishop of that city. While he was in Rome, persecution broke out in Lyons and nearby Vienne—these are the events discussed in Chapter 5—and Bishop Photinus perished. Upon his return to Lyons, Irenaeus was elected bishop of the church in that city. He served as such until his death, probably as a martyr, in 202.

Irenaeus was above all a pastor. He was not particularly interested in philosophical speculation nor in delving into mysteries hitherto unsolved, but rather in leading his flock in Christian life and faith. Therefore, in his writings he did not seek to rise in great speculative flights, but simply to refute heresy and instruct believers. Only two of his works survive: Demonstration of Apostolic Preaching, and Exposure and Refutation of Knowledge Falsely So-Called (also known as Against Heresies). In the first of these, he instructs his flock on some points of Christian doctrine. In the latter, he seeks to refute Gnosticism. In both, his goal is to expound the faith that he has received from his teachers, without adorning it with his own speculations. Therefore, the writings of Irenaeus are an excellent witness to the faith of the church toward the end of the second century.

Irenaeus, who sees himself as a shepherd, also sees God as above all a shepherd. God is a loving being who creates the world and humankind, not out of necessity nor by mistake—as Gnostics claimed—but out of a desire to have a creation to love and to lead, like the shepherd loves and leads the flock. From this perspective, the entirety of history appears as the process whereby the divine shepherd leads creation to its final goal.

The crown of creation is the human creature, made from the beginning as a free and therefore responsible being. That freedom is such that it allows us to become increasingly conformed to the divine will and nature, and thus to enjoy an evergrowing communion with our creator. But, on the other hand, the human creature was not made from the beginning in its final perfection. Like a true shepherd, God placed the first couple in Eden. They were not mature beings, but were rather “like children,” with their own perfection as such. This means that God’s purpose was that human beings would grow in communion with the divine, eventually surpassing even the angels.

The angels are above us only provisionally. When the divine purpose is fulfilled in the human creature, we shall be above the angels; for our communion with God will be closer than theirs. The function of angels is similar to that of a tutor guiding the first steps of a prince. Although the tutor is temporarily in charge of the prince, eventually the prince will rule even the tutor.

Humankind is to be instructed, not only by the angels, but also by the “two hands” of God: the Word and the Holy Spirit. Led by those two hands, humans are to receive instruction and growth, always with a view to an increasingly close communion with God. The goal of this process is what Irenaeus calls “divinization”—God’s purpose is to make us ever more like the divine. This does not mean, however, that we are somehow to be lost in the divine, nor that we shall ever be the same as God. On the contrary, God is so far above us that no matter how much we grow in our likeness to the divine we shall always have a long way to go.

But one of the angels was jealous of the high destiny reserved for humankind, and for that reason led Adam and Eve into sin. As a result of sin, the human creature was expelled from paradise, and its growth was thwarted. From that point on, history has unfolded under the mark of sin.

Although the actual course of history is the result of sin, the fact that there is history is not. God always had the purpose that there be history. The situation in paradise, as described in Genesis, was not the goal of creation, but its beginning.

From this perspective, the incarnation of God in Jesus Christ is not merely a response to sin. On the contrary, God’s initial purpose included being united with humankind. In fact, the future incarnate Word was the model that God followed in making humans after the divine image. Adam and Eve were so created that, after a process of growth and instruction, they could become like the incarnate Word. What has happened because of sin is that the incarnation has taken on the added purpose of offering a remedy for sin, and a means for defeating Satan.

Even before the incarnation, and from the very moment of the first sin, God has been leading humanity toward closer communion with the divine. For this reason, God curses the serpent and the earth, but only punishes the man and the woman. At the very moment of the fall, God is working for human redemption.

Israel has an important role in the drama of redemption, for it is in the history of the chosen people that the two “hands of God” have continued their work, preparing humankind for communion with God. Therefore, the Old Testament is not the revelation of a God alien to the Christian faith, but is rather the history of the unfolding redemptive purposes of the same God whom Christians know in Jesus Christ.

At the proper time, when humankind had received the necessary preparation, the Word was incarnate in Jesus Christ. Jesus is the “second Adam” because in his life, death, and resurrection a new humanity has been created, and in all his actions Jesus has corrected what was twisted because of sin. Furthermore, Jesus has defeated Satan, and this in turn has enabled us to live in renewed freedom. Those who are joined to him in baptism, and nourished in his body through communion, are also participants in his victory. Jesus Christ is literally the head of the church, which is his body. This body is nourished through worship particularly communion—and is so joined to its head that it is already receiving the first benefits of Christ’s victory. In his resurrection, the final resurrection has dawned, and all who are part of his body will partake of it.

Even at the end, when the Kingdom of God is established, God’s task as shepherd will not be finished. On the contrary, redeemed humanity will continue growing into greater communion with the divine, and the process of divinization will go on eternally, taking us ever closer to God.

In conclusion, what we find in Irenaeus is a grand vision of history, so that the divine purposes unfold through it. The focal point of that history is the incarnation, not only because through it God’s word has straightened the twisted history of humankind, but also because from the very beginning the union of the human with the divine was the goal of history. God’s purpose is to be joined to the human creature, and this has taken place in a unique way in Jesus Christ.
