This episode contains part of a voluminous work by the next author in the series, Irenaeus. He was a disciple of Polycarp, placing him two generations from the apostles. He lived between A.D. 120 and A.D 202. Irenaeus wrote as a bishop in Lyons, France, and found himself part of a global church embroiled in heresy and schism. Because of this he devoted much of his life to understanding and refuting the heretics of his day. This has been preserved in a five volume series, titled “Against Heresies.” This episode contains the fifth and final book in the series in which the author refutes these strange teachings.
