Catholicism is the religious tradition most historically associated with quinceañera thanksgiving Masses.
In many Catholic Latino communities, a quinceañera may attend a Misa de acción de gracias, or thanksgiving Mass, as part of the celebration. The service can include blessings, readings, prayers, and the presentation of the honoree to the congregation.
A quinceañera is not itself one of the seven sacraments of the Catholic Church. The religious service is an optional devotional element, while the reception and symbolic customs are social and family practices.
Practices differ widely. Some families hold a church service, some celebrate entirely outside a church, and some belong to other Christian denominations or no religion. Thus Catholic association is historically strong but does not make every quinceañera Catholic.
