3 It is gratifying to recall that We ourselves, on the first day of November of the Holy Year 1950, before a huge multitude of Cardinals, Bishops, priests, and of the faithful who had assembled from every part of the world, defined the dogma of the Assumption of the Blessed Virgin Mary into heaven where she is present in soul and body reigning, together with her only[1a] Son, amid the heavenly choirs of angels and Saints. Moreover, since almost a century has passed since Our predecessor of immortal memory, Pius IX, proclaimed and defined the dogma that the great Mother of God had been conceived without any stain of original sin, We instituted the current Marian Year And now it is a great consolation to Us to see great multitudes here in Rome - and especially in the Liberian Basilica - giving testimony in a striking way to their faith and ardent love for their heavenly Mother. In all parts of the world We learn that devotion to the Virgin Mother of God is flourishing more and more, and that the principal shrines of Mary have been visited and are still being visited by many throngs of Catholic pilgrims gathered in prayer.
