Orders of Service

An Order of Service (also know as an Order of the Day, or a Mass Book) guides your guests through the wedding ceremony.
In a Church service, it includes the words to hymns, prayers and titles of readings etc. In a civil ceremony, it usually lists
the order of proceedings, timings and readings. It can include whatever details you feel necessary to ensure the smooth running of your ceremony.

Mass Books tend to list the service, including Responses and Bidding Prayers in full.
