ABOUT THE AUTHOR: Saint John Cassian was a Christian theologian celebrated in both the Western and Eastern Churches for his mystical writings. He is known both as one of the "Scythian monks" and as one of the "Desert Fathers."
Saint John Cassian was a monk and theologian. Born in the region of Scythia Minor (today's Romania and Bulgaria). As a member of wealthy family he received a good classical education (he was bilingual, knew Latin and Greek). Died in Marseille in 435. Celebrated in both the Western and Eastern Churches for his mystical writings. Cassian is noted for bringing the ideas and practices of Egyptian monasticism to the early medieval West. Influenced St. Benedict, who included many of Cassian's principles into his monastic rule.
(This was read from The Philokalia Vol.1 this is part of The Institutes) Cassian’s short essays do an excellent job of diagnosing and giving remedy to 8 vices. Cassian’s explanations are deeply rooted in scripture and has many practical applications. This is a difficult, but rich read. My basic summary is that Cassian is strong advocate for intentional Godly community and for God’s grace and mercy that empowers our climb to holiness. There are a few things that I might disagree with Cassian on, but overall a great work that more people should read.
(Also if you decide to read this remember that it is written for Monks)
