Mother of the Church

In Roman Catholic Mariology, Mother of the Church (in Latin Mater Ecclesiae) is a title, officially given to Mary during the Second Vatican Council by Pope Paul VI. The title was first used in the 4th century by Saint Ambrose of Milan, as rediscovered by Hugo Rahner.

The title "Mother of the Church" was used by Pope Benedict XIV in 1748 and then by Pope Leo XIII in 1885. The title was also used by Pope John Paul II and is also found in the Catechism of the Catholic Church.

Pope John Paul II stated that overall the title indicates the Blessed Virgin Mary's maternity of Christ's faithful, as deriving from her maternity of Christ in that "Mary is present in the Church as the Mother of Christ, and at the same time as that Mother whom Christ, in the mystery of the Redemption, gave to humanity in the person of the Apostle John [cf. John 19:27]. Thus, in her new motherhood in the Spirit, Mary embraces each and every one in the Church, and embraces each and every one through the Church."

The Church has traditionally portrayed the Blessed Virgin Mary together with the apostles and disciples gathered at that first Pentecost, joined in prayer with the first members of the Church. The title, Mater Ecclesiae is found in the writings of Berengaud, bishop of Treves (d. 1125). In the 1895 encyclical Adjutricem populi (Helper of the People) Pope Leo XIII wrote, "She is invoked as Mother of the Church and the teacher and Queen of the Apostles". Following the title's usage by Leo XIII, it was later used many times in the teachings of John XXIII and Paul VI,John Paul II and Benedict XVI.

The use of the Mater Ecclesiae title to the Virgin Mary goes back to Ambrose of Milan in the 4th century, but this was not known until its 1944 rediscovery by Hugo Rahner. Rahner's Mariology, following Ambrose, sees Mary in her role within the Church. His interpretation, based solely on Ambrose and the early Fathers, greatly influenced Vatican II and Pope Paul VI, who, quoting Ambrose, declared Mary the "mother of the Church".
