The most glorious title of the Blessed Virgin, and the reason for all her greatness and privileges, is to be the Mother of God. At the celebration of the XV centenary of the Council of Ephesus, which defined the divine Motherhood of Mary, proclaiming it, in Greek, Theotocos, and in Latin, Deípara, Mother of God, Pope Pius XI instituted the feast that we celebrate today.
V/. Most Holy Mary.
R/. Pray for us.
