With effect from 1 September 2024, Percy has been appointed as Professor of Religion and Culture in the Faculty of Religious Studies and Philosophy at University of Saint Joseph in Macao.

In 2013, The Times Literary Supplement praised Percy for his work towards unity within the Anglican Communion and the Church of England, describing him as displaying a "peaceable, polite and restrained" approach whilst "making peace between competing communities of conviction".

[6] His doctoral thesis was titled "Signs, Wonders and Church Growth": The Theme of Power in Contemporary Christian Fundamentalism with Special Reference to the Works of John Wimber.

During Percy's tenure, the multi-award-winning Bishop Edward King Chapel (shortlisted for the Stirling Prize in 2013) and a new education centre (Harriet Monsell House) were built.

[18] Supporters of the dean criticised Christ Church's complaints process, as it was claimed no investigation or disciplinary hearing was necessary prior to his suspension from office and putting him on trial.

The statutory tribunal process Percy was subject to was presided over by Sir Andrew Smith, a High Court judge and estimated to have cost the college at least £1.9m.

In May 2020, 41 members of Christ Church's governing body published a letter they claimed to have sent to the Charity Commission accusing Percy of "unsound judgment" and of having breached his legal, fiduciary and safeguarding duties since the Smith tribunal.

[28] As with previous complaints, Christ Church referred the allegation to Thames Valley Police, the NST and was also party to bringing a case under the 2016 Clergy Discipline Measure.

[31] One of Britain's most senior Court of Appeal judges, Dame Sarah Asplin, President of Tribunals for the Church of England, carried out a detailed investigation.

Despite this, the Bishop of Oxford engaged in proactive, extensive and repeated measures to prohibit Percy from teaching and preaching, and also refused to license him, thereby depriving him of the possibility of any further paid ministry or pensionable service within the Church of England.

[34] The 2022 Annual Report of the Christ Church Governing Body stated that 'under the terms of the settlement, Dr Percy received monies to cover legal fees and compensation for early termination of his appointment.

[38] The warning stated that "in the context of a long running dispute with the former Dean, the Commission has determined there has been mismanagement and/or misconduct in the management and administration of the Charity" (para.

[39][40][41] His viewpoints typically argue for the "middle ground" between evangelical and catholic positions, with appeals to Anglican comprehensiveness, and the tradition of respecting theological differences.

[42] Percy's main interlocutors in his writings comprise a trinity of American theologians: Daniel W. Hardy, Urban T. Holmes III, and James F. Hopewell.

[46][47] However, his writings affirm orthodox Christian positions on the incarnation, atonement, resurrection and ascension; he has consistently defended the historicity of Jesus' healing and nature miracles.

[48] Noted for his work on fundamentalism and revivalism, for which he engages with sociology and anthropology, he was described in the academic journal Theology, by Nigel Rooms, as the British theologian who is the closest to being a "missionary anthropologist".

[49] In 2002, Percy co-founded the Society for the Study of Anglicanism with Tom Hughson, which meets annually at the American Academy of Religion and is now in a full partnership with Virginia Theological Seminary.

He has spoken and written about the threat of schism in the Anglican Communion, arguing that churches should embrace the diversity of belief that exists, rather than allowing such divisions to result in separation.

Illustrating this, he described Anglicanism as an "archipelago – a connection of provincial islands that shares doctrinal, liturgical and cultural aspects", as opposed to being "one vast, catholic continent".

[52] He made similar remarks following Jeffrey John's withdrawal as Bishop of Reading, in July 2003, suggesting debate on gay rights should instead be shifted towards reflecting on the "more central gospel themes".

[54] Percy described Welby's plans to send senior clergy on leadership courses, contained in the 2014 report of the Lord Green Steering Group,[55] as showing a poor judgment of the church's priorities and lacking in theological understanding.

In August 2016, Percy renewed his criticism of Welby, describing the direction he was leading the Church of England as being "driven by mission-minded middle managers" that alienated congregations and the wider British public.

[57] Percy has also commented on an emerging theological anaemia among bishops in the Church of England, and highlighted the weaknesses and risks this poses for Anglican polity.

Regarding the controversy surrounding the issue in the worldwide Anglican Communion, he noted that the church's position has alienated an increasingly progressive country, particularly the younger generation of Christians in Britain;[54] he also called on Justin Welby to formally apologise for the church's role in introducing homophobic teachings to cultures across the British Empire, during the 19th century:[60] In 41 of the 53 countries within the British Commonwealth, homosexual conduct is still regarded as a serious crime.

The Archbishop of Canterbury could begin the Primates' meeting by accepting responsibility for the part the Church of England has played in perpetrating this discrimination and the subsequent injustices – and publicly repenting of them.

[64] In the wake of the United Kingdom EU membership referendum in June 2016, Percy has argued that a national "failure of liberal values" was made evident by the result.

[67] A subsequent independent report by Lord Carlile of Berriew found that there was no basis in law for presuming that the allegations made against Bell could have been sustained.

That is why we must all protest, and invite everybody to show solidarity with the abused, and stand apart from the Church of England until such time as it submits, completely, to public standards of justice and truth…then repents, apologises and starts full and proper redress for its victims.

[73]Following the General Synod's narrow rejection of a motion to legalise the ordination of women as bishops in November 2012, Percy wrote in The Daily Telegraph criticising church leaders for failing to create sufficient consensus about the issue.

'"[78] Percy is also commended in Adam Sisman’s The Professor and the Parson for his role in managing a serial fraudster who was working in both church and higher education.
