St. Isaac the Syrian, Bishop of Nineveh, teacher of the spiritual life.
January 28
St. Isaac the Syrian lived in the seventh century and was for a short time Bishop of Nineveh before withdrawing to the solitary life in the mountains. His ascetical homilies, translated into Greek by the monks of St. Sabbas, became one of the most treasured spiritual books of the Orthodox Church.
He is commemorated on January 28 together with St. Ephrem the Syrian.
May 30
St. Isaac the Syrian lived in the seventh century. A monk from his youth, he was consecrated Bishop of Nineveh, but after only a short time he laid aside the episcopate and withdrew into the desert, giving himself wholly to stillness, prayer, and the study of the Scriptures until blindness and old age overtook him.
His Ascetical Homilies, born of that hidden life, speak of the mercy of God and the humble heart with a depth that has nourished monks and laity alike for centuries. He is commemorated on May 30.
September 28
St. Isaac the Syrian was born in the region of Qatar in the seventh century and became a monk, and for a short time bishop of Nineveh, before withdrawing to the mountains of Persia to live as a hermit. His ascetical homilies, translated into Greek at the Lavra of St. Sabbas, became one of the most cherished spiritual books of the Orthodox Church, teaching the love of God for all creation and the way of humility and prayer.
