What is the usual Spanish name for the quinceañera’s formal religious service?

The usual Spanish name for a quinceañera’s formal religious service is misa de acción de gracias.

The phrase translates as “thanksgiving Mass,” reflecting the practice of giving thanks for the celebrant’s life and asking for blessings as she enters a new stage. In Catholic families, this service may take place before the reception and can include readings, music, and a blessing.

Participation is not universal. Some families hold a quinceañera without a church service, while others belong to different Christian denominations or other faiths. The religious component therefore depends on family belief and local custom.

The service should not be confused with a wedding Mass. A quinceañera Mass is a birthday and coming-of-age observance, not a marriage ceremony.
