The religious ceremony traditionally held before or during many quinceañera celebrations is a Mass.
A quinceañera Mass, often called a thanksgiving Mass, gives the honoree and her family an opportunity to express gratitude and receive a blessing. It is commonly held in a Catholic church and may include special prayers, readings, music, and the presentation of symbolic gifts.
The religious service is separate from the reception, although the two events are often scheduled on the same day. Not every modern quinceañera includes a Mass: families may choose a secular celebration, follow another faith, or adapt the tradition to local customs.
