Many years ago I took a course on Gnosticism in Rome under Fr. Antonio Orbe, SJ, an expert on the subject. Gnosticism, an early heresy that threatened Christianity in the 2nd century eventually waned as a movement and its writings were destroyed. Until a large cache of gnostic writings was discovered recently in the sands of Egypt, most of what was known about the the gnostics came from the writings of St. Irenaeus, the bishop we honor today in our liturgy.

He said he was struck by how accurately and fairly Irenaeus reported what the gnostics taught in his writings, not distorting what they said or omitting their ideas. He was fair and respectful to friend and foe alike. He was a peace-maker.
