Congregación Mariana
Throughout the centuries the devotion to and the veneration of the Virgin Mary by Roman Catholics has both led to, and been influenced by a number of Roman Catholic Marian Movements and Societies. These societies form part of the fabric of Roman Catholic Mariology. As early as the 16th century, the Holy See endorsed the Sodality of Our Lady and Pope Gregory XIII issued a Papal Bull commending it and granting it indulgences and establishing it as the "mother sodality", and other sodalities were formed thereafter.
