Church Fathers

Bishop of Alexandria and defender of Nicene orthodoxy against Arianism.

Gregory of Nyssa, also known as Gregory Nyssen, was an early Christian theologian who served as the bishop of Nyssa from 372 to 376 and from 378 until his death in 394. He is venerated as a saint in Eastern Orthodoxy, the Catholic Church, Oriental Orthodox Churches, Anglicanism, and Lutheranism.

Hilary of Poitiers or St Hilarius was Bishop of Poitiers and a Doctor of the Church. He was sometimes referred to as the "Hammer of the Arians" and the "Athanasius of the West". His name comes from the Latin word for happy or cheerful.

Augustinian monk and Reformer whose Ninety-Five Theses sparked the Reformation.

Bishop of Antioch. Eusebius in his "Chronicle" places the name of Theophilus against that of Pope Soter (169-77), and that of Maximinus, Theophilus's successor, against the name of Eleutherus (177-93). This does not mean that Maximinus succeeded Theophilus in 177, but only that Theophilus and Maximinus flourished respectively in the times of Soter and Eleutherus. Lightfoot and Hort showed that Eusebius, having no such precise chronological data for the bishops of Antioch as he had for those of Rome and Alexandria, placed the names of the Antiochene bishops against those of contemporary Roman bishops (Lightfoot, "St. Ignatius", etc., II, 468 sq., and "St. Clement", etc., I, 224 sqq.). When therefore we find in the third book of Theophilus, "Ad Autolychum", that the writer was alive after the death (180) of Marcus Aurelius, it does not follow, as even writers like Harnack and Bardenhewer suppose, that Eusebius made a chronological blunder.
