As King Charles III prepares for his coronation on 6 May, the ceremony will remain a deeply Christian affair, but the monarch's long‑standing desire to reflect the UK's religious diversity is expected to reshape the understanding of his title 'Defender of the Faith'. Almost 30 years ago, Charles triggered controversy by suggesting he would prefer to be 'defender of faith' in general, rather than 'defender of the faith'.
The coronation oath itself will be unchanged from that sworn by his predecessors for nearly 500 years. However, for the first time, Archbishop of Canterbury Justin Welby will preface the oath with words stating that the Church of England 'will seek to foster an environment in which people of all faiths and beliefs may live freely'. This innovation reflects Charles's vision, which he has articulated since the death of Queen Elizabeth II.
In September 2022, Charles told faith leaders that as a 'committed Anglican' he had a 'duty to protect the diversity of our country, including by protecting the space for faith itself'. He also acknowledged the growing number of people with no religion, saying he felt bound to respect 'those who seek to live their lives in accordance with secular ideals'.
According to Ian Bradley, emeritus professor at the University of St Andrews, Charles's faith is 'deep and strong, but more questing, more intellectual, more complex' than his mother's. He is drawn to Eastern Orthodox Christianity and aspects of Islam, and has long emphasised the importance of the sacred in public life.
The coronation liturgy, produced in close consultation with the king, will include a greeting by leaders and representatives of other faiths, a significant departure from previous ceremonies. While the title 'Defender of the Faith' remains unchanged, its interpretation is being reimagined to encompass a broader, more inclusive role.
