times that Mary was preserved by God from the contagion of original sin. Eastern Catholics while not observing the Latin-Rite holy day, have no difficulty affirming it or even dedicating their churches to the Virgin Mary under this title. Centers for Mariological studies The formal study of Mariology within the circles associated with the Holy See took a major step forward between the Holy Year 1950 and 1958 based on the actions of Pope Pius XII, who authorized institutions for increased academic research into the veneration of the Blessed Virgin Mary. Pontifical Marian International Academy – The PAMI is an international pontifical organization connecting all Promoters of Mariology, Catholics, Orthodox, Protestants and Muslim. John XXIII with the Apostolic Letter Maiora in Dies defined the purpose of the PAMI: to promote and animate studies of Mariology through International Mariological Marian Congresses and other academic meetings and to see to the publication of their studies.

The Centro promulgates the teachings of Louis de Montfort, who was earlier canonized by Pius XII. It publishes the monthly Madre e Regina, which promulgates the Marian orientation of Montfort. Marianum was created in 1950 and entrusted to the Order of Servites. It is authorized to grant all academic degrees, including a doctorate in theology. Since 1976, every two years the Marianum organizes international conferences to find modern formulations which approximate the mystery of Mary.

It coordinates activities of Marian centres in Italy, and organizes Marian pilgrimages and Marian study weeks for priests. In addition it started Marian youth gatherings and publishes the journal Madonna. Of these organizations, the Marianum Pontifical Theological Faculty is the most
