Prince William has a sense of duty that “runs deep” and he “wants to draw a line in the sand” when it comes to addressing speculation over his future role of head of the Church of England. This week, the Prince of Wales will represent his father, the King, at the enthronement of the new Archbishop of Canterbury, Dame Sarah Mullally, at Canterbury Cathedral.

Unlike the King or his late grandmother Elizabeth II, William, 43, is not known to be a regular churchgoer or a devout Christian. It had led to questions about his personal faith, especially as he will be Supreme Governor of the Church of England and known as ‘Defender of the Faith’ when he becomes King.

There had also been speculation that William may consider not taking on the formal role held by the country’s monarchs since Henry VIII. However, sources close to the future King have now spoken about his “quiet faith” and “commitment to the Church of England” ahead of Wednesday’s service, which he will attend with the Princess of Wales.
