Philip the Apostle
According to a legend, Chet received estates near Kostroma in 1330 during the reign of Ivan I of Moscow and was baptized as Zachary. He also had a vision of the Virgin Mary with prestanding Philip the Apostle and hieromartyr Hypatius of Gangra, which resulted in his healing from sickness. In a gratitude for healing at that place was established Hypatian Monastery.
