LONDON >> It will be a coronation of many faiths and many languages.

King Charles III, keen to show that he can be a unifying figure for everyone in the United Kingdom, will be crowned in a ceremony that will for the first time include the active participation of faiths other than the Church of England.

Buddhist, Hindu, Jewish, Muslim and Sikh leaders will take part in various aspects of the coronation, the Archbishop of Canterbury’s Office said Saturday as it revealed details of a service it described as an act of Christian worship that will reflect contemporary society.

The ceremony also will include female bishops for the first time, as well as hymns and prayers sung in Welsh, Scottish Gaelic and Irish Gaelic, as well as English.

“The service contains new elements that reflect the diversity of our contemporary society,’’ Archbishop Justin Welby, spiritual leader of the Church of England, said in a statement.

Built around the theme “Called to Serve,” the coronation service will begin with one of the youngest members of the congregation — a Chapel Royal chorister — greeting the king. Charles will respond by saying, “In his name and after his example, I come not to be served but to serve.”

The moment is meant to underscore the importance of young people in the world today, according to Lambeth Palace, the home of the Archbishop of Canterbury.

The service also will include many historic elements underscoring the ancient traditions through which power has been passed on to new kings and queens throughout the centuries.
