Venerable Neilos the Ascetic of Sinai

Saint Neilos the Ascetic of Sinai, a native of Constantinople, lived during the V century and was a disciple of Saint John Chrysostom, who exerted a tremendous influence upon their lives and their spiritual struggles.1 After receiving a fine education, the Saint was appointed to the important post of prefect of the capital while still a young man. During this period, Neilos was married and had children, but the couple found courtly life distasteful.

About the year 390, by mutual consent, they decided to abandon the world and entered monasteries. Neilos's wife and daughter went to one of the women’s monasteries in Egypt, while he and his son Theódoulos went to Mount Sinai, where they settled in a cave, which they dug out with their own hands. For forty years this cave served as the abode of Saint Neilos. By fasting, vigil, and prayer, he attained a high degree of spiritual perfection. People began coming to him from every occupation and social rank, from the Emperor down to the farmer, and all of them received counsel and comfort from the Saint.

On Sinai, Saint Neilos wrote many soul-profiting works to guide Christians on the path of salvation. In one of his letters there is an angry denunciation of the Emperor Arkadios, who had unjustly exiled Saint John Chrysostom. The ascetical writings of Saint Neilos are widely known: they are perfectly executed in form, profoundly Orthodox in content, and are clear and lucid in expression. His Ascetic Discourse is found in Volume I of the English Philokalia.

Saint Neilos suffered many misfortunes in the wilderness. Once, Saracens captured his son Theódoulos, whom they intended to offer as a sacrifice to their pagan gods. By the Saint's prayers the Lord rescued Theódoulos, and his father found him with the Bishop of Emessa, who had ransomed the young man from the barbarians. This bishop ordained both of them as presbyters. After ordination they returned to Sinai, where they lived as ascetics together until Saint Neilos reposed. His holy relics were transferred to Constantinople in the reign of Justin II (565-578), and were placed in the church of the Holy Apostles.

The Greek Philokalia has a quote from Saint Neilos beneath his icon: "The state of prayer is a passionless, settled disposition of the soul which, by supreme love, transports the wisdom-loving mind to spiritual heights." (See the English Philokalia, 153 Sections. Concerning Prayer, # 53).


1 In earlier editions of the Synaxaristes and the Menaion, it was erroneously stated that Saint Neilos lived during the reign of Emperor Maurikios (582-602). This was corrected in later editions, since he was a disciple of Saint John Chrysostom, and was esteemed by Emperor Arkadios because of his virtues.
