He was born in Tuscany and given the name Hildebrand. He became a monk, and assisted several successive Popes in reforming and purifying the Church. He was elected pope in 1073 and took the name of Gregory VII. He fought single-mindedly to free the Church from harmful influences and dependence on the state. This brought him into conflict with the Emperor Henry IV, who was excommunicated by Gregory, then submitted to him, then changed his mind and besieged and captured Rome. Gregory was “rescued” by the Norman Robert Guiscard, who captured Rome amid scenes of appalling violence, and Gregory had to flee to Salerno, where he died.

He was born in the north of England, near the monastery of Wearmouth. He joined that monastery, and spent all his life there or at Jarrow, teaching and writing. He was the outstanding ecclesiastical author of his time. He wrote commentaries on Scripture; an ecclesiastical history of the English people, which is a unique and irreplaceable resource for much of early English history; and the first martyrology (collection of saints’ lives) to be compiled on historical principles. He was also the first known writer of English prose, though this has not survived. He died at Jarrow on 25 May 735: he taught and worked until the last moments of his life, which are narrated by Cuthbert in today’s Office of Readings. He is venerated as the “light of the Church” in the Dark Ages, and as a forerunner of the 8th and 9th century renaissance of the Western Church.
