Royal Wedding Ceremony Details Revealed

The official program for the royal wedding of Prince William and Catherine Middleton has been released by Buckingham Palace. The 27-page program includes the full order of service, a personal message of thanks from the bride and groom, and a new black and white photograph of Will and Kate taken by engagement photographer and invited wedding guest Mario Testino.

The message from Prince William and Catherine reads, "We are both so delighted that you are able to join us in celebrating what we hope will be one of the happiest days of our lives. The affection shown to us by so many people during our engagement has been incredibly moving, and has touched us both deeply. We would like to take this opportunity to thank everyone most sincerely for their kindness."

The order of the service includes full details on the processions, music, hymns, prayers and reading.

Middleton will walk down the aisle to the coronation anthem, "I was Glad" by Sir Charles Hubert Hastings Parry. It was composed for the crowning of Prince William's great-great-great grandfather Edward VII at Westminster Abbey in 1902.

When William and Catherine are wed, they will say the following: "I (groom/bride's name), take thee (bride/groom's name) to my wedded wife/husband, to have and to hold from this day forward, for better, for worse; for richer, for poorer; in sickness and in health; to love and to cherish, till death do us part, according to God's holy law; and thereto I give thee my throth.

The program confirms that Catherine will break with royal tradition, just as Princess Diana did, by not promising to "obey" her new husband. Instead, Catherine will vow to "love, comfort, honor and keep" William.

The bride's brother, James Middleton, will deliver the only reading at the royal wedding from Romans 12: 1-2, 9-18, which says, "Let love be genuine; hate what is evil, hold fast to what is good; love one another with mutual affection; outdo one another in showing honor."
