In 2012, he wrote and presented How God Made the English, a three-part documentary series tracing the history of English identity from the Dark Ages to the present day. In 2013 he presented a documentary on Thomas Cromwell and his place in English ecclesiastical and political history. His 2015 series Sex and the Church on BBC Two explored how Christianity has shaped western attitudes to sex, gender and sexuality throughout history.

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.

MacCulloch was awarded a Doctor of Divinity (DD) degree by the University of Oxford in 2001; the DD is the highest degree awarded by the university.

In 1996 his book Thomas Cranmer: A Life won the James Tait Black Memorial Prize. His 2003 book Reformation: Europe's House Divided 1490–1700 won the 2004 National Book Critics Circle Award, the 2004 British Academy Book Prize and the Wolfson History Prize. A History of Christianity: The First Three Thousand Years was published in September 2009 with a related 6-part television series called A History of Christianity which first aired on BBC4 in 2009 and then on BBC2 and BBC4 in 2010. The book won McGill University's Cundill Prize, a $75,000 prize, the largest such prize in Canada at the time.

MacCulloch was elected a Fellow of the Society of Antiquaries of London (FSA) in 1978, a Fellow of the Royal Historical Society (FRHistS) in 1982, and a Fellow of the British Academy (FBA) in 2001. In 2003, he was awarded an honorary Doctor of Letters (DLitt) degree by the University of East Anglia. He was knighted in the 2012 New Year Honours for services to scholarship. While Debretts gives his formal style as "Prof Sir", MacCulloch has expressed the preference that he not be addressed in that manner, in accordance with protocol which dictates that clergy holding knighthoods are addressed as "Sir" only if so honoured before their ordination.

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.

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.
