Anglican Commemoration
Bishop of Lincoln & Scholar
October 9 · d. 1253
also known as Grosseteste, Robert of Lincoln
English bishop, natural philosopher, and ecclesiastical reformer whose prolific writings on optics, theology, and pastoral care established him as one of the most learned men of the thirteenth century. His courageous resistance to papal abuses and royal interference in clerical appointments made him a model of episcopal integrity.
Grosseteste's veneration rests primarily on his documented intellectual achievements and principled episcopal resistance rather than on miraculous tradition. Matthew Paris records that at his death supernatural signs were observed, and an informal local cult developed, but he was never formally canonized. His inclusion in the Anglican calendar reflects Protestant and Anglican appropriation of his resistance to papal authority as proto-reformational witness.
Robert Grosseteste was born around 1168, likely in Suffolk. He studied at Oxford and possibly Paris, mastering theology, natural philosophy, mathematics, and languages including Greek and Hebrew — a rare combination for Western scholars of his era. He served as the first chancellor of Oxford University (a role still being formalized) and lectured to the early Franciscan community at Oxford, forming a lasting bond with the friars.
In 1235, Grosseteste was appointed Bishop of Lincoln, then England's largest diocese. As bishop, he conducted rigorous visitations enforcing clerical discipline, education, and morality, frequently clashing with cathedral chapters, religious houses, and the papacy itself. His central contention was that the cure of souls was the bishop's paramount duty and could not be subordinated to administrative convenience or financial interests.
His prolific writings encompassed biblical commentary, scientific treatises on light and optics (De Luce, De Lineis, Angulis et Figuris), the pastoral allegory Château d'Amour, and extensive correspondence. He translated Aristotle's Nicomachean Ethics and the works of Pseudo-Dionysius directly from Greek, advancing Western access to key philosophical sources. Roger Bacon credited him as an inspiration for empirical investigation.
In 1253, Grosseteste wrote a landmark letter to Pope Innocent IV refusing a papal provision to a Lincoln canonry, asserting the bishop's duty to conscience over papal administrative mandate. He died on October 9, 1253. Never formally canonized, he is commemorated in the Anglican calendar for his learning, pastoral integrity, and prophetic witness against ecclesiastical corruption.
Almighty God, you gave your servant Robert Grosseteste special gifts of grace to understand and teach the truth revealed in Christ Jesus: Grant that by this teaching we may know you, the one true God, and Jesus Christ whom you have sent; who lives and reigns with you and the Holy Spirit, one God, for ever and ever. Amen.
