Against Heresies

In Against Heresies, St. Irenaeus, Bishop of Lyons, delves into the various Gnostic schools that thrived in the early days of Christianity, prior to the Nicene period. He boldly counters these divergent beliefs, labeling them as heresies in stark contrast to what he defines as the true, universal faith of orthodox Christianity. This compelling work reveals the rich tapestry of beliefs, debates, and divisions that characterized the nascent Christian era. (Summary by JoeD)
