PRINCESS JOANNA OF AUSTRIA (1535-1573)
Demise of Princess Juana, Regent of Spain, the Emperor Charles V's daughter. She died with her Jesuit vows. "The only female Jesuit in the Church's history," writes Hugo Rahner.
Born in the royal court of Madrid, Joanna was the daughter of Charles V, the first king of united Spain and was also the sister of King Philip II of Spain. She served as regent to Philip during his trip to England to marry at the age of 17, her first cousin. The marriage was cut short when her husband died of tuberculosis. However, Joanna was pregnant by that time, and the future Portuguese king Sebastián I was born. Joanna returned to Spain at the request of her father, leaving her new-born son with her mother-in-law, the Portuguese Queen Catherine of Austria. Joanna never remarried and never returned to Portugal. She never saw her son Sebastian again. Meanwhile she used her power to compel the Society of Jesus to secretly make her a member. Ignatius Loyola had received official papal recognition for his order in 1540, but the Jesuit leadership had decided not to establish an associated group for pious woman. But Joanna was determined to join the Society and had sufficient influence to prevail. Jesuit leaders admitted her in 1554 under the alias of "Mateo Sanchez," and she remained a member of the Society for the rest of her life as a permanent Scholastic. When she pronounced three vows as a Jesuit, absolute secrecy was enjoined on everyone. Her faith intensified, and since she could not publicly be an official part of the Jesuits, in 1557, Joanna founded the Convent of Our Mother of Consolation for the nuns of the order of Poor Clares. Joanna died at the age of 37 of tumours and was buried in the convent she had founded.
