Irenaeus - Irenaeus' Theology and Contrast With Gnosticism

Irenaeus' Theology and Contrast With Gnosticism

The central point of Irenaeus' theology is the unity and the goodness of God, in opposition to the Gnostics' division of God into a number of divine "Aeons", and their distinction between the utterly transcendent "High God" and the inferior "Demiurge" who created the world. Irenaeus uses the Logos theology he inherited from Justin Martyr. Irenaeus was a student of Polycarp, who was said to have been tutored by John the Apostle. (John had used Logos terminology in the Gospel of John and the letter of 1 John). Irenaeus prefers to speak of the Son and the Spirit as the "hands of God".

His emphasis on the unity of God is reflected in his corresponding emphasis on the unity of salvation history. Irenaeus repeatedly insists that God began the world and has been overseeing it ever since this creative act; everything that has happened is part of his plan for humanity. The essence of this plan is a process of maturation: Irenaeus believes that humanity was created immature, and God intended his creatures to take a long time to grow into or assume the divine likeness. Thus, Adam and Eve were created as children. Their Fall was thus not a full-blown rebellion but rather a childish spat, a desire to grow up before their time and have everything with immediacy.

Everything that has happened since has therefore been planned by God to help humanity overcome this initial mishap and achieve spiritual maturity. The world has been intentionally designed by God as a difficult place, where human beings are forced to make moral decisions, as only in this way can they mature as moral agents. Irenaeus likens death to the big fish that swallowed Jonah: it was only in the depths of the whale's belly that Jonah could turn to God and act according to the divine will. Similarly, death and suffering appear as evils, but without them we could never come to know God.

According to Irenaeus, the high point in salvation history is the advent of Jesus. Irenaeus believed that Christ would always have been sent, even if humanity had never sinned; but the fact that they did sin determines his role as a savior. He sees Christ as the new Adam, who systematically undoes what Adam did: thus, where Adam was disobedient concerning God's edict concerning the fruit of the Tree of Knowledge of Good and Evil, Christ was obedient even to death on the wood of a tree. Irenaeus is the first to draw comparisons between Eve and Mary, contrasting the faithlessness of the former with the faithfulness of the latter. In addition to reversing the wrongs done by Adam, Irenaeus thinks of Christ as "recapitulating" or "summing up" human life. This means that Christ goes through every stage of human life, from infancy to old age, and simply by living it, sanctifies it with his divinity. Although it is sometimes claimed that Irenaeus believed Christ did not die until he was older than is conventionally portrayed, the bishop of Lyons simply pointed out that because Jesus turned the permissible age for becoming a rabbi (30 years old and above), he recapitulated and sanctified the period between 30 and 50 years old, as per the Jewish custom of periodization of human life, and so touches the beginning of old age when one becomes 50 years old. (see Adversus Haereses, book II, chapter 22).

In the passage of Adversus Haereses under consideration, Irenaeus is clear that after receiving baptism at the age of thirty, citing Luke 3:23, Gnostics then falsely assert that "He preached only one year reckoning from His baptism," and also, "On completing His thirtieth year He suffered, being in fact still a young man, and who had by no means attained to advanced age." Irenaeus argues against the Gnostics by using scripture to show that Jesus lives at least several years after his baptism by referencing 3 distinctly separate visits to Jerusalem. The first is when Jesus makes wine out of water, He went up to the Paschal feast-day, after which He withdraws and is found in Samaria. The second is when Jesus goes up to Jerusalem for Passover and cures the paralytic, after which He withdraws over the sea of Tiberias. The third mention is when He travels to Jerusalem, eats the Passover, and suffers on the following day.

Irenaeus quotes scripture, which we reference as John 8:57, to suggest that Jesus ministers while in his 40's. In this passage, Jesus' opponents want to argue that Jesus has not seen Abraham, because Jesus is too young. Jesus' opponents argue that Jesus is not yet 50 years old. Irenaeus argues that if Jesus was in his thirties, his opponents would've argued that He's not yet 40 years, since that would make Him even younger. Irenaeus' argument is that they would not weaken their own argument by adding years to Jesus' age. Irenaeus also writes that "The Elders witness to this, who in Asia conferred with John the Lord's disciple, to the effect that John had delivered these things unto them : for he abode with them until the times of Trajan. And some of them saw not only John, but others also of the Apostles, and had this same account from them, and witness to the aforesaid relation."

In Demonstration (74) Irenaeus reinforced his view that Jesus was at least 45 with the statement "For Herod the king of the Jews and Pontius Pilate, the governor of Claudius Caesar, came together and condemned Him to be crucified." This would place the crucifixion no earlier then AD 42.

Irenaeus conceives of our salvation as essentially coming about through the incarnation of God as a man. He characterizes the penalty for sin as death and corruption. God, however, is immortal and incorruptible, and simply by becoming united to human nature in Christ he conveys those qualities to us: they spread, as it were, like a benign infection. Irenaeus therefore understands the atonement of Christ as happening through his incarnation rather than his crucifixion, although the latter event is an integral part of the former.

By comparison, according to the Gnostic view of Salvation, creation was perfect to begin with; it did not need time to grow and mature. For the Valentinians, the material world is the result of the loss of perfection which resulted from Sophia's desire to understand the Forefather. Therefore, one is ultimately redeemed, through secret knowledge, to enter the pleroma of which the Achamoth originally fell.

According to the Valentinian Gnostics, there are three classes of human beings. They are the material, who cannot attain salvation; the psychic, who are strengthened by works and faith (they are part of the church); and the spiritual, who cannot decay or be harmed by material actions. Essentially, ordinary humans—those who have faith but do not possess the special knowledge—will not attain salvation. Spirituals, on the other hand—those who obtain this great gift—are the only class that will eventually attain salvation.

In his article entitled "The Demiurge," J.P. Arendzen sums up the Valentinian view of the salvation of man. He writes, "The first, or carnal men, will return to the grossness of matter and finally be consumed by fire; the second, or psychic men, together with the Demiurge as their master, will enter a middle state, neither heaven (pleroma) nor hell (whyle); the purely spiritual men will be completely freed from the influence of the Demiurge and together with the Saviour and Achamoth, his spouse, will enter the pleroma divested of body (húle) and soul (psuché)."

Irenaeus is also known as one of the first theologians to use the principle of apostolic succession to refute his opponents.

In his criticism of Gnosticism, Irenaeus made reference to a Gnostic gospel which portrayed Judas in a positive light, as having acted in accordance with Jesus' instructions. The recently discovered Gospel of Judas dates close to the period when Irenaeus lived (late 2nd century), and scholars typically regard this work as one of many Gnostic texts, showing one of many varieties of Gnostic beliefs of the period.
