Purpose

''Against Heresies'' can be dated to sometime between 174 and 189 AD, as the list of the Bishops of Rome includes Eleutherius, but not his successor Victor. The earliest manuscript fragment of ''Against Heresies'', P. Oxy. 405, dates to around 200 AD. Irenaeus' primary goal in writing ''Against Heresies'' was to attack sects that deviated from his own form of Christianity, mainly the

and Marcionites. In particular, he sought to disprove what he saw as incorrect interpretations of scripture on the part of Gnostics such as Valentinus. Irenaeus sought to present "what was understood as an authentic form of century-old Christian tradition against various forms of Gnosticism." As James VanderKam notes, elements of this early Christian tradition drawn upon by Irenaeus include apocalyptic traditions such as 1 Enoch. As bishop, Irenaeus felt compelled to keep a close eye on the Valentinians and to safeguard the church from them. In order to fulfill this duty, Irenaeus became well informed of Gnostic doctrines and traditions. His studies of Gnosticism eventually led to the compilation of this treatise.

Main ideas

Irenaeus argued that orthodox Christianity was passed down to him from the apostles who knew Jesus personally, while the

and Marcionites were distorting this apostolic tradition. While the Gnostics offered salvation through secret knowledge available only to a few, Irenaeus contended that the true doctrines of the Christian faith are the same taught by bishops in different areas. While many of the Gnostics viewed the material world as flawed and from which believers sought to escape to an eternal realm of spirit, Irenaeus saw creation as good and ultimately destined for glorification. As Mark Jeffrey Olson points out, is quoted more than any other verse from the letters of Paul in ''Against Heresies'': Both Irenaeus and the Valentinians use this verse to argue for their own understandings of the resurrection of the dead. The Valentinians believed that resurrection was a purely spiritual phenomenon, while Irenaeus insisted that Christians would be raised from the dead in fleshly bodies. According to Irenaeus, this verse was used by the Gnostics to argue that "the handiwork of God is not saved."
