Holy Name of Mary
This feast is a counterpart to the Feast of the Holy Name of Jesus (January 3); both have the possibility of uniting people easily divided on other matters.
The feast of the Most Holy Name of Mary began in Spain in 1513 and in 1671 was extended to all of Spain and the Kingdom of Naples. In 1683, John Sobieski, king of Poland, brought an army to the outskirts of Vienna to stop the advance of Muslim armies loyal to Mohammed IV in Constantinople. After Sobieski entrusted himself to the Blessed Virgin Mary, he and his soldiers thoroughly defeated the Muslims. Pope Innocent XI extended this feast to the entire Church.
