Mary, Mother of God, Mother of the Holy Vine

Pope Pius XII hereby made it a magisterial teaching and authenticated this title as a mystery to be delved into profoundly as the basis for a special spirituality. Since Jesus spoke of the vine and branches at the Last Supper, the title is Eucharistic. The application of it to Our Lady by both popes makes it a Marian title as well. Therefore, it can be the foundation of a distinct Marian Eucharistic spirituality developed through “prayerful meditation” and study, as the Venerable Pope Pius XII stated. He identifies her as the “Mediatrix of Eucharistic Holiness.”
