0 ENCYCLICAL OF POPE PIUS XII ON THE POSSIBILITY OF DEFINING THE ASSUMPTION OF THE BLESSED VIRGIN MARY AS A DOGMA OF FAITH TO THE PATRIARCHS, PRIMATES, ARCHBISHOPS, AND OTHER ORDINARIES AT PEACE AND IN COMMUNION WITH THE APOSTOLIC SEE. The Christian people have never ceased to invoke and experience the Blessed Virgin Mary's assistance, and therefore they have, at all times, venerated her with ever growing devotion.
