When Charles is crowned King of England
Prince Charles has long been a proponent of religion - all types of religion. One of the titles given to the King or Queen of England is "Defender of the Faith" - the faith here refering to the Christian faith. However, Charles has long said that he would want to change this title to "Defender of the Faiths" in keeping with his snycretistic religious world view.
Along this line, it has emerged this week that when the time finally comes for Prince Charles to become King of England, his coronation will not be a distinctly Christian ceremony, breaking with the tradition of many centuries. Instead it will be a decidedly multi-faith event. See here.
