Here are a few things to consider…
Procession
Does the bride want to come into church with her father or mother or other significant relative?
Does the bride want to come into church alone?
Do you want the bridesmaids to precede the bride? [American style]
Do you want the bridesmaids to enter after the bride? [British tradition]
Readings
What readings would you like?
A portion of Scripture [the Bible] is essential, but other readings or poems can also be included.
Music
Do you want any Hymns?
And if you do, do you want an organist? or a choir?
What music do you want playing as the bride enters the church?
What music do you want playing as bride and groom leave the church?
[Please discuss your options with the vicar]
Do you want to decorate the church?
If your wedding is in winter do you want extra heating in the church?
Do you want a video of your wedding?
Do you want to have a Champagne Reception whilst the photographs are being taken?
Do you want to include a candle ceremony?
Who will be your witnesses and sign the register? [often best man and chief bridesmaid]
Please discuss these options with the Vicar
