Nicholas Ridley ( – 16 October 1555) was an English Bishop of London (the only bishop called "Bishop of London and Westminster"). Ridley was one of the Oxford Martyrs burned at the stake during the Marian Persecutions, for his teachings and his support of Lady Jane Grey. He is remembered with a commemoration in the calendar of saints (with Hugh Latimer) in some parts of the Anglican Communion (Church of England) on 16 October. Early years and advancement (c.1500–50) Ridley came from a prominent family in Tynedale, Northumberland. He was the second son of Christopher Ridley, first cousin to Lancelot Ridley and grew up in Unthank Hall from the old House of Unthank located on the site of an ancient watch tower or pele tower. As a boy, Ridley was educated at the Royal Grammar School, Newcastle, and Pembroke College, Cambridge, where he proceeded to Master of Arts in 1525. Soon afterward he was ordained as a priest and went to the Sorbonne, in Paris, for further education. After returning to England around 1529, he became the senior proctor of Cambridge University in 1534. Around that time there was significant debate about the Pope's supremacy. Ridley was well versed on Biblical hermeneutics, and through his arguments the university came up with the following resolution: "That the Bishop of Rome had no more authority and jurisdiction derived to him from God, in this kingdom of England, than any other foreign bishop." He graduated B.D. in 1537 and was then appointed by the Archbishop of Canterbury, Thomas Cranmer, to serve as one of his chaplains. In April 1538, Cranmer made him vicar of Herne, in Kent. In 1540–1, he was made one of the King's Chaplains, and was also presented with a prebendal stall in Canterbury Cathedral. In 1540 he was made Master of Pembroke College and in 1541 was awarded the degree of Doctor of Divinity. In 1543 he was accused of heresy, but he was able to beat the charge. Cranmer had resolved to support the English Reformation by gradually replacing the old guard in his ecclesiastical province with men who followed the new thinking. Ridley was made the Bishop of Rochester in 1547, and shortly after coming to office, directed that the altars in the churches of his diocese should be removed, and tables put in their place to celebrate the Lord's Supper. In 1548 he helped Cranmer compile
