Below is the Order of a Catholic Wedding Mass (not just a Ceremony). Priests will vary parts of the wedding service a bit, but this is the program they follow closely. The Catholic Wedding Mass usually lasts about one hour. They may last longer if the number of wedding guests receiving Communion at the Mass is above 200 people.
When most couples plan a Wedding in a Catholic Church, the #1 Question they need to answer is: “Are we having a Catholic Wedding Ceremony or a Full Nuptial Mass?” This decision is made in consultation with the Parish Priest or Deacon who will be presiding over the service and is the Most Important decision to make. This decision effects the length of the service and effects how many musical selections will be needed as well as how many musicians you might need to hire.
Deciding whether or not your Catholic Service will be a Ceremony or a Full Nuptial Mass effects most of the Music-Related Decisions you’ll make later on. Once this decision is made, then most other decisions affecting the music for the wedding service itself follow.
