On Sunday, Oct. 20, King Charles and his wife Queen Camilla attended religious services at St. Thomas's Anglican Church in Sydney, Australia. During the visit, as the Daily Mail notes, the monarch signed the country's first official Bible and the book of common prayer.

King Charles III embarked on his first tour since his cancer diagnosis as he and Queen Camilla travel throughout Australia this week. The country greeted the royal duo on Oct. 18 with a spectacular display of photos projected onto the Sydney Opera House from their visits over the years.
