Leo IX
Leo IX (1002–54), pope. Born of noble, bilingual parents in Alsace, he was educated at Toul, mainly by Adalbert, later bishop of Metz. As a deacon of the pre-Gregorian unreformed Church he was given command of troops provided by the bishop to put down a Lombard rebellion. He was most successful and gained a reputation for handling men skilfully. In 1027 he was chosen bishop of Toul. He reformed the canons who served the cathedral, and the monasteries of Moyenmoutier and Saint-Dié. He also held many synods and visitations. In 1048 the Emperor Henry III chose him as pope, and Leo was acclaimed by the Roman clergy and people.
Once pope, he travelled through Italy, Germany, and France, holding twelve reforming synods. This process was a useful innovation which greatly helped to eliminate simony and nepotism, long taken for granted, and clerical marriage. At Reims, for example, his synod led to the deposition of certain bishops, while others, including the host-bishop of the assembly, had to make their peace privately with the pope by resigning their charge and accepting it again from him, significantly with a new crozier. The movement spread through Europe, obtaining English participation and support through delegates sent to the councils. It was paradoxical that Leo IX, usually regarded as the initiator of the Gregorian Reform which liberated the Church from both the emperors and the Roman nobility, owed his appointment to both. The ideal of independence from the secular power emerged later; in early days the Gregorian papal reformers were ready to work with and through the kings. So close was their partnership that at the end of his life Leo tried to form a political and military alliance against the Norman invaders of southern Italy. He led an army against them, but was defeated and captured at Civitella. Peter Damian and others criticized severely this military involvement: battles should be fought by emperors, not popes.
Another important setback just before his death was the breach with Constantinople, which eventually led to the Eastern Schism. He sent legates to Constantinople to deal with accusations of heresy which came from Michael Cerularius, the patriarch: he did not live to see the full conflict unfold of mutual accusation and separation. Leo placed his bed and his coffin side by side in St. Peter's and died there on 19 April. Within forty years, it is said, seventy cures, believed to be miraculous, took place; Leo was acclaimed as a saint; in 1087 his relics were enshrined. Another link between Leo IX and England was his friendly relationship with Edward the Confessor. Edward had vowed to go on pilgrimage to Rome but found himself unable to do so. Instead Leo accepted his plan to refound Westminster Abbey. Feast: 19 April.
