On Easter Sunday, April 20, 2014, the Duke and Duchess of Cambridge attended service at St. Andrew’s Church in Sydney, Australia. At the church, William and Catherine signed the First Fleet Bible and Prayer Book. The Bible was used in 1788 in the first Christian service held in Australia. The Bible has since been signed by various members of the British royal family including Queen Elizabeth II in 1954. Photos by Getty Images and Bauer Griffin.
