The Plan of Redemption
From the treatise Against Heresies by Saint Irenaeus, bishop (125-202)
The plan of redemption through the Incarnation
God is man’s glory. Man is the vessel which received God’s action and all his wisdom and power.
Just as a doctor is judged in his care for the sick, so God is revealed in his conduct with men. That is Paul’s reason for saying: God has made the whole world prisoner of unbelief that he may have mercy on all. He was speaking of man, who was disobedient to God, and cast off from immortality, and then found mercy, receiving through the Son of God the adoption he brings.
If man, without being puffed up or boastful, has a right belief regarding created things and their divine Creator, who, having given them being, holds them all in his power, and if a man perseveres in God’s love, and in obedience and gratitude to him, he will receive greater glory from him. It will be a glory which will grow ever brighter until he takes on the likeness of the one who died for him.
He it was who took on the likeness of sinful flesh, to condemn sin and rid the flesh of sin, as now condemned. He wanted to invite man to take on his likeness, appointing man an imitator of God, establishing man in a way of life in obedience to the Father that would lead to the vision of God, and endowing man with power to receive the Father. He is the Word of God who dwelt with man and became the Son of Man to open the way for man to receive God, for God to dwell with man, according to the will of the Father.
For this reason the Lord himself gave as the sign of our salvation, the one who was born of the Virgin, Emmanuel. It was the Lord himself who saved them, for of themselves they had no power to be saved. For this reason Paul speaks of the weakness of man, and says: I know that no good dwells in my flesh. He means that the blessing of our salvation comes not from us but from God. Again, he says: I am a wretched man; who will free me from this body doomed to die? Then he speaks of a liberator, thanks to Jesus Christ our Lord.
Isaiah says the same: Hands that are feeble, grow strong! Knees that are weak, take courage! Hearts that are faint, grow strong! Fear not – see, our God is judgment and he will repay. He himself will come and save us. He means that we could not be saved of ourselves but only with God’s help.

St. Irenaeus (125-202) was born is Asia Minor, probably at Smyrna. He was well educated and probably knew and was influenced by men who knew the Apostles, especially St. Polycarp, who was a pupil of St. John the evangelist. According to Gregory of Tours, Polycarp sent Irenaeus as a missionary to Gaul, where he was a priest under St. Pothinus at Lyons. Irenaeus was sent to Rome in 177 with a letter from his fellow Christians to Pope St. Eleutherius pleading for leniency to the Montanists in Phrygia. In Irenaeus’ absence a violent persecution of Christians broke out at Lyons, claiming Pothinus as one of its martyrs. Irenaeus was named Bishop of Lyons on his return in 178. He was the first great Catholic theologian. Irenaeus wrote in Greek and two of his profound works survived in tact. His five-book treatise against the heresy of Gnosticism constitutes an invaluable source of information on Church Christ established from its beginnings to the end of the second century. His work also conveys the apostolic tradition in it and is a powerful testimony to the primacy of the Pope.
