Mamas
Martyr, Μάμας
St. Mamas was a young shepherd of Caesarea in Cappadocia, born to parents who had themselves suffered imprisonment for Christ. Living simply in the hills with his flock, he confessed the faith openly during the persecutions of the third century and endured torture and death rather than deny his Lord.
John the Faster of Constantinople
Hierarch, Ιωάννης ο Νηστευτής
St. John IV, called the Faster, was a goldsmith of Constantinople who embraced the monastic life and rose, against his own wishes, to the patriarchal throne in 582. He was famed for his extreme fasting, his almsgiving, and his gift of healing, and he composed canons of penance that were long used in the Church.
Theodosius of the Kiev Caves
Venerable, Θεοδόσιος των Σπηλαίων
St. Theodosius was born near Kiev in the eleventh century and from youth longed for the monastic life, fleeing his mother's opposition to join St. Anthony in the caves above the Dnieper. He became abbot of the Kiev Caves and gave the brotherhood the cenobitic rule of the Studion monastery.
Diomedes, Julian, Philip and those with them
Martyr, Διομήδης, Ιουλιανός, Φίλιππος
The holy martyrs Diomedes, Julian, Philip, Eutychian, Hesychius, Leonides, Eutychius, Philadelphus, Melanippus and the holy woman Parthagape suffered together for Christ in the time of the pagan persecutions. Tradition relates that they were put to death by various torments, some by fire and some by the sword, refusing to the end to deny the faith.
Eleazar and Phinehas the Righteous
Saint, Ελεάζαρ και Φινεές
The righteous Eleazar was the son of Aaron and succeeded him as high priest of Israel, serving beside Joshua in the division of the Promised Land.

Venerable, Κοσμάς ο Ερημίτης
