What is the formal religious service sometimes held for a quinceañera called?

The formal religious service sometimes held for a quinceañera is called a Misa de Acción de Gracias.

This Spanish phrase means “Thanksgiving Mass.” In Catholic families, it may be held before the reception and provides an opportunity for the celebrant and relatives to give thanks, receive a blessing, and express hopes for the young woman’s future.

The Mass is not required for every quinceañera. Some celebrations are secular, while others include a church service with a different local format. Customs can also vary according to the parish, country, family, and wishes of the celebrant.

The religious service should not be confused with a wedding ceremony. A quinceañera may contain formal processions, special clothing, music, and family roles, but it does not make the celebrant married. Its central purpose is thanksgiving and a coming-of-age observance rather than marriage.
