Eusebius explains, “Irenaeus, whose name means ‘peaceable’ and who by temperament was a peacemaker, pleased and negotiated for the peace of the churches.” There was a dispute between Bishop Viktor of Rome and the Asian dioceses over the length of a church fast, he was threatening excommunication over this dispute. Irenaeus interceded, arguing that “the dispute is not only about the day, but also about the actual character of the fast.” He pointed out the variations were differences in practice extending back to their forefathers. Although they had their differences, “they all lived in peace with one another, and so do we: the divergences in the fast emphasizes the unanimity of the faith.” […]
This discourse on the Apostle’s Creed was delivered by St Augustine to a local church council in North Africa. In this treatise he repeats his classical explanation of the Trinity:
The Father is truly God, the Son is truly God, and the Holy Spirit is truly God.
The Father is not sometimes the Son, and the Father is not sometimes the Holy Spirit, and God is One. We have God the Father, God the Son, and God the Holy Spirit, but “there are not three Gods in that Trinity, but One God and one substance.” […]
St Irenaeus elegantly summarizes his refutation of Gnosticism, “If Christ was not born, neither did He die. If Christ did not die, neither did He rise from the dead. If He did not rise from the dead, He did not conquer death and abolish its reign. If Christ did not conquer death, how are we to ascend to the light, we who from the beginning have been subject to death? Those who rob man of redemption do not believe that God will raise man from the dead.” […]
St Irenaeus teaches us, “The redemption depends on the real Incarnation, the real suffering on the Cross, and the real resurrection of the flesh. All three of these are a scandal for Gnosticism. On their view, Mary is not really Mother of God, and Christ did not really suffer, NO, the heavenly Christ escaped before the man Jesus suffered, and there can be no question at all of an actual resurrection of the flesh. Underlying this refusal of the flesh and its saving role in the Incarnation is a confusion between the human spirit (nous) and the divine Holy Spirit.” The Gnostics want to replace the Holy spirit with the human spirit. Irenaeus preaches “the salvific character of the Incarnation of God’s Son and Word.” […]
