Saint Nil the Ascetic was born in Constantinople, received a good education, and was appointed prefect of the capital. Realizing the vanity of worldly life, he left the world, giving his possessions to the poor and retreating with his son Theodulus to Mount Sinai. Here he labored in fasting and prayer for forty years, living in a cave dug by his own hands. His wisdom attracted many, and he became a spiritual mentor.
The saint rebuked Emperor Arcadius for the exile of Saint John Chrysostom. His son Theodulus was captured by barbarians, but he was saved by the bishop of the city of Emesa, who later ordained him as a presbyter. Nil, not wishing to remain in the city, returned to Sinai with his son, where he peacefully departed this life.
From him remain numerous soul-beneficial letters and works on faith and piety, in which he shared his experience and teachings.
