Cassian
Cassian (John Cassian)c.360–433, abbot. Born probably in Romania, Cassian became a monk at Bethlehem, but left in c.385 with his friend Germanus to study monasticism in Egypt. Here he was influenced by the teaching of Evagrius Ponticus. In c.400 he was in Constantinople, where he was ordained deacon and became the fervent disciple and defender of John Chrysostom, who had favoured and promoted Origenist monks. For a time Cassian seems to have shared the charge of the cathedral treasury. A few years later, however, when Chrysostom was deposed at the Synod of the Oak, his disciples, Cassian included, left Constantinople for Italy, where he pleaded Chrysostom's cause with the pope, Innocent I. From then onwards his life was spent in the West.
Ordained priest probably at Marseilles, Cassian founded two monasteries there in c.415: one for men (at the tomb of Victor), the other for women. At this time Provence was overrun by refugees from the barbarian invasions; the monastic movement, approved by some and attacked by others, both Christian and pagan, needed leadership, example, and an interpreter of the Egyptian tradition to Gaul. This Cassian became through his monastic writings, the Institutes and the Conferences.
The Institutes were concerned with life in community, the Conferences are supposedly sermons of Egyptian hermits, but inevitably there is much overlap between the two treatises. Cassian insisted that monastic life was apostolic in origin, based on the practice of the early Church of the Acts of the Apostles. He recognized the theoretical superiority of the hermit life, but seemed in practice to dissuade anyone ‘imperfect’ from undertaking it. According to some scholars the solitude which was higher than the community was ‘not naked solitude but the society of hermits with a common worship and discipline’. This, however, was not how his teaching was always understood. It does seem certain that Cassian's own monasteries were, like Benedict's, schools for beginners or cenobites. It was through Benedict's recommendation of Cassian as a spiritual guide to his monks that Cassian's writings attained very wide diffusion. With Augustine and Gregory he was a standard monastic guide throughout the Middle Ages and beyond.
Cassian's other works include a treatise on the Incarnation, requested by Leo to acquaint Western readers with the teaching of Nestorius. More damaging to his posthumous reputation was his teaching on Grace. Here he reacted so strongly against what he saw as Augustine's excesses on predestination that he is sometimes called the founder of semi-Pelagianism. A well-meant reaction led to his falling into error, teaching that the first steps towards the Christian life were taken by the human will which only later was helped powerfully by divine grace.
There are no Acts of Cassian, no record of miraculous cures at his tomb in Marseilles. But his body, that of a big man, was kept in the later Middle Ages (and probably before), in a marble tomb on four pillars. Urban V, an Avignon pope and formerly abbot of Marseilles, caused his head to be enclosed in a silver casket and engraved ‘Head of St. Cassian’. In the diocese of Marseilles but not outside it his feast was kept on 23 July. His name is in the Roman Martyrology; as a writer for monks and a monastic founder. Feast: 23 July: 29 February in the East.
