Kontakion in the Plagal of the Fourth Tone Creation found delight and joy in thine august nativity and the good cheer of thy numberless miracles on thy divine memorial. Now bestow thereof richly on our souls and wash clean the stains of our every sin, Euthymius most righteous, that we may chant: Alleluia!

Righteous Euthymios the Great

Reading from the Synaxarion:

This Saint, who was from Melitene in Armenia, was the son of pious
parents named Paul and Dionysia. He was born about 377. Since his
mother had been barren, he was named Euthymius-which means "good cheer"
or "joy"-for this is what his parents experienced at his birth. He
studied under Eutroius, the Bishop of Melitene, by whom he was ordained
and entrusted with the care of the monasteries of Melitene. Then,
after he had come to Palestine about the year 406, he became the leader
of a multitude of monks. Through him, a great tribe of Arabs was
turned to piety, when he healed the ailing son of their leader
Aspebetos. Aspebetos was baptized with all his people; he took the
Christian name of Peter, and was later consecrated Bishop for his tribe,
being called "Bishop of the Tents." Saint Euthymius also fought
against the Nestorians, Eutychians, and Manichaeans. When Eudocia, the
widow of Saint Theodosius the Younger, had made her dwelling in
Palestine, and had fallen into the heresy of the Monophysites which was
championed in Palestine by a certain Theodosius, she sent envoys to Saint
Symeon the Stylite in Syria (see Sept. 1), asking him his opinion of
Eutyches and the Council of Chalcedon which had condemned him; Saint
Symeon, praising the holiness and Orthodoxy of Saint Euthymius near whom
she dwelt, sent her to him to be delivered from her error (the holy
Empress Eudocia is commemorated Aug. 13). He became the divine oracle of
the Church, or rather, "the vessel of divine utterance," as a certain
historian writes. He was the instructor and elder of Saint Sabbas the
Sanctified. Having lived for ninety-six years, he reposed in 473, on January
20.

Apolytikion in the Fourth Tone
Be glad, O barren one, that hast not given birth; be of good cheer,
thou that hast not travailed; for a man of desires hath multiplied thy
children of the Spirit, having planted them in piety and reared them in
continence to the perfection of the virtues. By his prayers, O Christ our
God, make our life peaceful.
