 The Inn has had a Chaplain since at least 1400 , where a court case is recorded as being brought by the " Chaplain of <unk> Inn " . During the 16th century the Inn began hiring full @-@ time preachers to staff the Chapel — the first , John <unk> , was appointed in 1576 . A radical Puritan in a time of religious conflict , <unk> held his post for only a short time before being replaced by a Thomas Crooke in 1580 . After Crooke 's death in 1598 Roger Fenton served as preacher , until his replacement by Richard <unk> , later Master of Catherine Hall , Cambridge , in 1616 . Gray 's Inn still employs a Preacher ; Michael Doe , former Bishop of Swindon and more recently General Secretary of the United Society for the Propagation of the Gospel , was appointed in 2011 .
