Saint Ivo of Chartres
Feast Day: May 23
Born in Beauvais, France, Ivo became a canon regular of St. Augustine at Saint-Quentin. He taught Scripture, theology and canon law there before becoming prior in 1078, and was elected bishop of Chartres in 1090. He was a councilor to King Philip I until he denounced the king’s plan to divorce his wife to marry a count’s third wife. Ivo was imprisoned briefly by the king, but the pope secured his release. Ivo was involved in two controversies of his age: He mediated several investiture disputes and zealously protested simony in the papal court. Three treatises helped secure his reputation as one of the most learned canonists of his time.
