To be, in the manner of the Virgin of the Annunciation, the instrument of Christ carrying out the will of the Father in the reality of the present moment, in the midst of the world, "wherever Christ has His rights."

The members of the Institute recognize in Mary Immaculate their mother and teacher in the faith and the apostolic mission. They also recognize in her their perfect model, she whose life was one of total assent to the will of God. That is why the Institute has chosen for its patronal feast the Annunciation, the day on which the entire Church celebrates the mystery of the Virgin Mary's Fiat.
