St. Vincent Pallotti always desired to be one among those who were present in the community of the Cenacle and a special fruit of the spiritual marriage with Mary is the foundation of the Union of Catholic Apostolate for the honour and under the special care of the Blessed Mary, Queen of Apostles. Pallotti expects of the members as his spiritual heirs, to receive Mary not only as Patroness but first of all as a Mistress of spiritual life. That is why in his spiritual testament he invites us to the Jerusalem Cenacle, which is a school of Mary, the Spouse of the Holy Spirit. Here, in our Pallottine Cenacle, we can contemplate and imitate Mary primarily as a woman obedient to the voice of the Holy Spirit.
