Saint Alexander, Founder of the Monastery of the “Unsleeping Ones,” was born in Asia and received his education at Constantinople. He spent some time in military service but, sensing a calling to other service, he left the world and received monastic tonsure in one of the desert monasteries near Antioch under the guidance of Igumen Elias.
Having advanced through all the degrees of monastic obedience, he received a blessing from the igumen to dwell in the wilderness. The saint lived an ascetical life in the wilderness, taking only the Holy Gospel with him. Afterwards, the Lord summoned him to preach to pagans. He converted to the faith the local city-head Rabbul, who afterwards prospered in the service of the Church, attaining the rank of bishop, and for thirty years, he occupied the bishop’s cathedra in the city of Edessa.
Finally, Saint Alexander settled not far from the Euphrates River. Monks gathered around him, attracted by the loftiness of his prayerful asceticism and spiritual experience. A monastery of 400 monks eventually sprang up there.
Then the holy igumen in his prayerful zeal decided to offer never-ceasing praise to the Lord at the monastery both by day and by night. For three years the holy abba prayed that God might reveal to him whether it was pleasing to Him to establish such a monastic rule. He received an answer by divine revelation. All the monks were divided into twenty-four watches of prayer. Changing shifts each hour, two choirs sang the holy Psalms both day and night, except when divine services were celebrated in church. Hence the name “Monastery of Unsleeping Ones,” since the ascetics offered unceasing praise to God.
Saint Alexander guided the monastery on the Euphrates for twelve years. Thereafter, having left the experienced Elder Trophimus as igumen, he set off with some chosen brethren through the cities bordering on Persia, to preach the Gospel. Having arrived at Constantinople, capital of the Byzantine Empire, he also established a monastery there with his Rule of unceasing praise. The abba died at a great old age after fifty years of monastic struggles. His death occurred in the year 430.
Saint Alexander is also commemorated on July 3.
