Sodality of Our Lady
The Sodality of Our Lady was formed in 1563 in Rome by members of the Society of Jesus and has remained the official Marian society of the Holy See for centuries. In 1584, Pope Gregory XIII issued a Papal Bull commending this Sodality, granting it indulgences and establishing it as the "mother Sodality". The Bull "Gloriosae Dominae" of Pope Benedict XIV increased the privileges of the sodality and the 1948 Apostolic Constitution Bis Saeculari of Pope Pius XII summarized the historical and contemporary relevance of the sodality.
