Quinceañeras have been a custom among Hispanics since pre-Columbian days, when indigenous tribes in South America inducted young women into the community on their 15th birthdays. Over time, this rite of passage has evolved into the kind of lavish ceremony one might associate with a debutante ball.
The Roman Catholic Church recently has taken steps to institutionalize the ceremony by introducing a prayer book especially for quinceañeras. The Order for the Blessing on the Fifteenth Birthday, available in English and Spanish, is a collection of prayers and benedictions specifically designed to "honor the Latino cultural heritage" and "encourage young women to renew their baptismal commitment," according to the book, published by the United States Conference of Catholic Bishops.
Streamlining the ceremony was no easy task. Because quinceañeras are not considered sacraments, no official ritual book exists. Priests are free to tailor the ceremonies according to the family's requests or their own ideas about what is appropriate.
It took a committee of 10 bishops, priests, nuns and laypeople, representing Cuba and Spain, almost a decade to reach consensus on the prayer book, which consists of Scripture readings, blessings and prayers, said Sister Doris Turek of the Conference. Although a similar book was published in 1976, this is the first to be approved by the Vatican.
