When the prince saw St Febronia, he fell in love with her because of her piety, wisdom and virtue, and vowed to marry her after being healed. St Febronia healed the prince and became his wife. The holy couple loved each other through all their ordeals. The haughty boyars did not wish to have a princess of common origin, and they urged that the prince leave her. St Peter refused, and so they banished the couple. They sailed off on a boat from their native city along the River Oka, and St Febronia continued to console St Peter. Soon the wrath of God fell upon the city of Murom, and the people begged the prince return together with St Febronia.
The holy couple was famous for their piety and charity. They died on the same day and hour, June 25, 1228, having received the monastic tonsure with the names David and Evphrosyne. The bodies of the saints were put in the same grave.
Sts Peter and Febronia showed themselves exemplary models of Christian marriage, and are considered the patron saints of newly-weds.
