Irenaeus, Bishop & Martyr

June 28, 2021 all-day

If theology is thinking about faith and arranging those thoughts in some systematic order, then Irenaeus has been righty recognized by both Catholics and Protestants as the first great systematic theologian. He was a third generation Christian, having been discipled by Polycarp who was discipled by John. He in turn took Christianity to Lyon in southern France.
Iraneaus’s enduring fame rests mainly on his large treatise, entitled Against Heresies. Here Irenaeus describes the major Gnostic systems thoroughly, clearly, and often with biting humor. This defense of Christianity has become a classic.
