Our Righteous Father Marcellus, Abbot of the Monastery of the Unsleeping Ones
Saint Marcellus, who was from the city of Apamea in Syria, was born of renowned parents. Adorned with virtue and learning, he succeeded Saint Alexander to the abbacy of the Monastery of the Unsleeping about the year 460. This monastery was so named because the monks there were divided into three ranks, and took turns in succession for the execution of the sacred services both day and night, and thus ceaselessly sent up praise to God, without any lapse. The author of this practice was the aforementioned Alexander. As the biographer of both these Saints writes: "Later, a venerable monastery was established near the mouth of Pontus - that is, the place where the Black Sea tracts into the Bosphorus - and he introduced a rule that, though new, was superior to any found elsewhere; that is, that henceforth they should never be any cessation in the hymnody offered to God, but that through an unbroken succession of those that served in turn, there should be achieved this continuous and unceasing glorification of our Master."
Apolytikion in the Plagal of the Fourth Tone
The image of God, was faithfully preserved in you, O Father. For you took up the Cross and followed Christ. By Your actions you taught us to look beyond the flesh for it passes, rather to be concerned about the soul which is immortal. Wherefore, O Holy Marcellus, your soul rejoices with the angels.
Kontakion in the Fourth Tone
Though clad in a mortal body, O Marcellus most wise, thou strovest to emulate the Angels' choirs in divine perpetual hymnody. And as an unsleeping shepherd of thy monastics, thou wast an example of true prayer and devoutness; O Father, intercede with the Lord, that He would save our souls.
