THIS DAY IN CHURCH HISTORY
Historical Events in Church Annals for July 30:
Death of Saint Peter Chrysologus, bishop and Doctor of the Church. For more on him, see TODAY'S LITURGY.
Death of Saint Olaf Skottkonung, king of Sweden. Not to be confused with Saint Olaf, king of Norway, this Olaf was converted by Saint Sigfrid and established Christianity in Sweden. It was one of the few cases in history where two saints fought each other in battle as in the case of both kings in which Olaf of Sweden defeated Olaf of Norway. When he refused to sacrifice to pagan gods, rebellious followers murdered Olaf of Sweden in Stockholm.
Death of Blessed Anthony della Chiesa, a Dominican priest from Vercelli in northern Italy.
