What I regard as a really distinctive trait of our two orders, and what seems to me to be without a precedent in all the religious orders I know of, is the fact, as I have said, that we embrace the religious life in the name and for the glory of the Blessed Virgin, and for the sake of devoting ourselves to her, that is to say, our bodies and all that we possess, in order to make her known, loved and served.Religious life is to Christianity what Christianity is to humanity. It is as imperishable in the Church as the church is imperishable in human society. For this reason, it would be futile to pretend to re-establish Christianity without the institutions which permit men to practice the evangelical counsels.
However, it would be difficult and inopportune to try to revive these institutions today under the same forms they had before the Revolution. But no form is essential to the religious life. One can be a religious under a secular appearance. It will be less offensive to the misguided. It will be more difficult for them to be opposed. The world and the Church will be even further edified. Let us then form a religious association by pronouncing the three vows of religion, but without name or costume. Nova bella elegit Dominus (The Lord had chosen new wars); and let us put the entire plan under the protection of Mary Immaculate, to whom her Divine Son has reserved the final victories over hell.Let us be, my child,... let us be, in our humility the heel of the Woman.
