Hypatius of Bithynia
Saint Hypatius of Bithynia was a monk and hermit of the fifth century. A Phrygian, he became a hermit at the age of nineteen in Thrace. He then traveled to Constantinople and then Chalcedon with another hermit named Jason. He became abbot of a hermitage at Chalcedon.
He was an opponent of Nestorianism and sheltered Saint Alexander Akimetes and others whose safety was threatened by the Nestorians.
He is credited with halting a revival of the Olympic games because of their pagan origins.
His feast day is June 17 in the Eastern Orthodox and Byzantine Catholic Churches.
