Saint Rudesind was a Galicianbishop and abbot. He was also a regional administrator and military leader under his kinsmen, the Kings of León. Rudesind was born into the nobility: his father was Count Gutierre Menéndez, brother-in-law to Ordoño II and supporter of Alfonso III of León, and his mother was St. Ilduara Eriz, daughter of count Ero Fernández. His sister Hermesenda became wife of Count Pelayo González and mother-in-law of count Gonzalo Menéndez. Rudesind was the grandson of Ermesenda Gatónez, sister of his predecessor in the see of Mondoñedo, Bishop Sabarico II, and was also related to the abbess Saint Senorina. He became a monk at a young age and became bishop of Mondoñedo at the age of 18. He served as Bishop from 925 to 950, then after a hiatus in which his nephew Arias Núnez filled the role, again served briefly from 955 to 958, to be followed again by Arias. Another nephew, Arias Peláez, would later hold the see.
Rudesind had already served as bishop of Mondoñedo - Dumio. After the killing of Sisnand in the battle of Fornelos, Rudesind was appointed administrator of the See of Iria Flavia, and he was in charge of that diocese from 968 to 977. After 977, he retired from his sees.
Career as abbot
Rudesind succeeded St. Franquila as abbot of Celanova. As abbot of Celanova, he was a leading figure of his time, and received visits from religious leaders throughout Galicia and Portugal who wanted spiritual advice. A deacon named Egila, in a donation that he made to Celanova, wrote this to Rudesind: "To you, eminent bishop, Rudesind, holiest father, true teacher, who teaches your subjects with your words and deeds...". He earned a reputation for performing miracles.
Veneration
In 1601, his relics were exhumed and placed in a silver urn at the principal altar of the church of Celanova Abbey.
Legends
A legend told of Rudesind concerns his birth. His mother had previous children, but they had all died in infancy. When her husband Gutierre went on an expedition to Coimbra with Alfonso III, Ilduara accompanied him. She prayed at the hermitage of San Salvador on Mount Coruba, after climbing up to it alone and barefoot. There she received the knowledge, from Saint Michael, that she would bear a son who would become not only a great leader of men but also a holy man. In gratitude, she ordered the construction of a church there and remained until Rudesind had been born. She wanted to baptize her son at San Salvador, but the cart used to haul up the baptismal fontbroke down. The workers went to get another cart. Meanwhile, however, Saint Michael had the broken cart move up the hill on its own accord.
