He was a Fellow of St. John's College, Cambridge in 1537. He was Dean of Durham 1551 to 1553, and again 1559 to 1560. During his time as Dean he was responsible for removing ornamentation from Durham Cathedral. He was somewhat isolated. In exile, he was at Zurich, Frankfurt and Strasburg. He wrote additional material for a book of homilies by Jean Calvin (1553).
