Queen Esther: Patron saint of crypto-Jews
Faced with threat of execution for Jewish observance, Sephardi conversos created the festival of Santa Esterica to replace Purim
When the Spanish Catholic monarchs Ferdinand and Isabella established the Spanish Inquisition in 1478, many Jews converted to Catholicism outwardly. Inwardly, they kept practicing Judaism in secret, becoming anusim, conversos, or crypto-Jews.
Queen Esther was an inspiration to the anusim in that she modeled a way for them to remember and retain their true, hidden Jewish identity while integrating into the society around them. The conversos implemented a strategy to be able to continue practicing Jewish customs while hiding their observance by inserting a Jewish tradition into a Catholic practice or “syncretism” — the mixing of rituals from different religions.
When the Roman Catholic Church formally recognizes a person as a saint, this person is canonized. A person who has not been canonized may, however, still be referred to as a saint if it is believed that they are “completely perfect in holiness.” The crypto-Jews took advantage of this loophole.
Although Queen Esther was not canonized by the Catholic Church, the anusim transformed her into Saint Esther. They called her Santa Ester or Santa Esterica. They were able to continue honoring Purim by reinventing it as “The Festival of Saint Esther.”
