A traditional Catholic quinceañera often includes a Catholic Mass.
The religious service is commonly called a quinceañera Mass or Misa de acción de gracias, a Mass of thanksgiving. Families may use it to give thanks for the honoree's life and to ask for guidance as she enters a new stage.
The Mass is not required for every modern quinceañera. Religious practice varies among families, and some celebrations are entirely secular. In a Catholic service, the honoree may participate in prayers, readings, or a dedication, depending on local parish customs.
The church service is usually only one part of the occasion. A reception may follow with a formal entrance, a meal, speeches, music, dancing, and photographs. These social traditions differ substantially across countries and families.
