Irenaeus of Lyon
Unknown author / Wikimedia Commons, Public domain Public domainSource page

Irenaeus, from Asia Minor, became bishop after the Lyon persecution of 177. His Against Heresies attacks teachers he groups as falsely named 'gnosis,' especially Valentinian systems, and defends a four-gospel collection and an apostolic rule of faith. He is a principal source for what those teachers said, and also a hostile one.

Raised in Smyrna, Irenaeus became bishop of Lyon after the martyrdoms of 177. Against Heresies attacks Gnostic systems and gives the first full argument for a four-Gospel canon and apostolic succession.
