"So in like manner, in the order of grace, the head and the members are born of one and the same Mother" --St. Louis de Montfort

The entire body--head and members--of a child is born of one and the same mother. Mary, espoused by the Holy Spirit, gave birth to Christ. In the Bible we find references to the Mystical Body of Christ, with Christ as the Head and His followers the members. If this is the case, then we too must be born of Mary, our Mother, for else we do not belong to His Body.
