Order of Celebrating Matrimony within Mass is a preferred form of the Catholic wedding liturgy when both the bride and the groom are Catholic.
The Order of Celebrating Matrimony states that the celebration of marriage "should normally be celebrated within Mass; receiving holy communion together strengthens the couple's love and lifts up all present into communion with Christ and one another.
Because this form includes both Mass and the Celebration of Matrimony, it typically lasts between 45 and 90 minutes, depending on the length of elements such as the readings, homily, music, procession, and so on.
