In a traditional quinceañera ceremony, what is the thanksgiving Mass called in Spanish?

A traditional quinceañera thanksgiving Mass is called a Misa de acción de gracias.

The phrase translates as “Mass of thanksgiving.” In Catholic families, the religious service may take place before the reception and gives the honoree an opportunity to give thanks for her life and family. The priest may also bless the honoree and pray for her future.

The Mass is not universal. Many quinceañeras are celebrated without a church service, especially when the family is not Catholic or when local customs differ. A quinceañera is therefore both a cultural celebration and, for some families, a religious observance.

The reception that follows may include formal clothing, a court of honor, a waltz, symbolic gifts, and a meal. These elements vary substantially between countries and families.
