Prince Harry and Meghan Markle will make their wedding modern, but with his grandmother heading the Church of England, Saturday's service will still be a traditional Anglican ceremony.
The couple's influence is more likely to be found in the mood and feel of the event at St. George's Chapel in Windsor Castle, rather than the structure.
But the frame will remain that of a classic church service in England.
Here is a summary of what to expect:
– Keep Peace –
A Wedding Service of the Church of England begins with a welcome and a hymn.
David Conner, the dean of Windsor, the chaplain's cleric, will give the prelude.
This is followed by the explanations and pledges s.
The presiding minister asks if anyone, for some reason, knows why the couple is not allowed to marry lawfully, and says they should declare it immediately or keep it at peace forever.
Justin Welby, archbishop of Canterbury, will then officiate the vows
The archbishop is the senior primate of the Church of England and the spiritual leader of Anglicans worldwide.
The wording depends on which version of the marriage service the couple prefers.
Some opt for very traditional language and explanations, while others favor more modern interpretations.
Markle has to recite all of Harry's first names: Henry Charles Albert David. Royal brides have often stumbled upon this hurdle.
Both use the answer "I want", whereupon the pastor declares them husband and wife.
At this point the spouses are legally married.
– US pastor's sermon –
The hour-long service will then be provided with hymns, a Bible reading, the Lord's Prayer and a sermon.
The main address of the wedding is held by Michael Curry, the Anglican leader of the United States
The Primate of the Episcopal Church will write his own address on the nature and duties of marriage.
Curry, the country's first African-American leader, is a lively, vivacious speaker in the US tradition and could turn the star around in a rigorous, formal environment.
Markle's father is an Episcopalist, while his mother is a member of another Protestant church.
Nevertheless, Markle attended a private Roman Catholic girls' school in Los Angeles.
She was baptized by us in the Church of England in March.
It is believed that she joined the Church of England out of respect for Queen Elizabeth, although the decision also removes doubts about the couple's reputation in the royal family.
The ministry will end with the national anthem "God bless the queen".
Then the couple has to go and sign the marriage register.
Harry will bow to Queen Elizabeth, and his bride will break off as they leave.
– State Church –
For marriages to be legal in England, they must be performed by or in the presence of a person entitled to register marriages in the district.
The marriage must be entered in the marriage register and signed by both parties, two witnesses, the person who performed the ceremony and the person who registered the marriage, if it is not the head of the ceremony.
Couples can marry in England at 18 or 16 with parental consent.
Runaway English couples aged 16-18 burned to Gretna Green, the first village in Scotland where they could marry under Scottish law without their parents' sayings.
