Pope Pius XII
Mystici Corporis Christi §111
Mystici Corporis Christi: On the Mystical Body of Christ
111 May she, then, the most holy Mother of all the members of Christ, to whose Immaculate Heart We have trustfully consecrated all mankind, and who now reigns in heaven with her Son, her body and soul refulgent with heavenly glory - may she never cease to beg from Him that copious streams of grace may flow from its exalted Head into all the members of the Mystical Body. May she throw about the Church today, as in times gone by, the mantle of her protection and obtain from God that now at least the Church and all mankind may enjoy more peaceful days.
