Diarmaid MacCulloch  Diarmaid Ninian John MacCulloch (; born 31 October 1951) is an English historian and academic, specialising in ecclesiastical history and the history of Christianity. Since 1995, he has been a fellow of St Cross College, Oxford; he was formerly the senior tutor. Since 1997, he has been Professor of the History of the Church at the University of Oxford. Though ordained a deacon in the Church of England, he declined ordination to the priesthood because of the Church's attitude to homosexuality. In 2009 he encapsulated the evolution of his religious beliefs: "I was brought up in the presence of the Bible, and I remember with affection what it was like to hold a dogmatic position on the statements of Christian belief. I would now describe myself as a candid friend of Christianity." MacCulloch sits on the editorial board of the "Journal of Ecclesiastical History". Diarmaid MacCulloch was born in Kent, England, to parents Nigel J. H. MacCulloch (an Anglican priest) and Jennie MacCulloch ("née" Chappell). He attended Hillcroft Preparatory School and Stowmarket Grammar School in Suffolk. He subsequently studied history at Churchill College, Cambridge, where he obtained a Bachelor of Arts degree in 1972; this was promoted to a Master of Arts degree in 1976. During that period, he was also organ scholar at the college. After completing a Diploma in Archive Administration at Liverpool University in 1973, he then returned to Cambridge to complete a PhD degree in 1977 on Tudor history under the supervision of Geoffrey Elton, combining this with a position as Junior Research Fellow at Churchill College. MacCulloch joined the Gay Christian Movement in 1976, serving twice on its committee and briefly as honorary secretary. From 1978 to 1990 he tutored at Wesley College, Bristol, and taught church history in the department of theology at the University of Bristol. He interrupted his teaching to study for the Oxford Diploma in Theology (awarded 1987) at Ripon College Cuddesdon. In 1987 he was ordained a deacon in the Church of England and from 1987 to 1988 he served as a non-stipendiary minister at All Saints' Clifton with St John's in the Diocese of Bristol. However, in response to a motion put before the General Synod in 1987 by Tony Higton regarding the sexuality of clergy, he declined ordination to the priesthood and ceased to minister at Clifton.
