Mother of the Faithful People, Mater populi fidelis: title and iconography

Mater Populi Fidelis, origin and meaning of the Marian title

The title Mater Populi Fidelis (“Mother of the Faithful People”) is one of the most profoundly ecclesial Marian titles of the Catholic tradition. While titles such as Theotókos or Mater Dei underline Mary’s relation to Christ, Mater Populi Fidelis underlines her relation to the People of God, the pilgrim Church that she accompanies and for which she intercedes. The title articulates the twofold Mariological dimension defined by the Second Vatican Council in Lumen Gentium: Mary as Mother of Christ and as Mother of the Church (Mater Ecclesiae).

The expression has roots in Christian antiquity. The concept of Mary as mother of all the faithful is found already in Origen (third century), who interpreted Jn 19:27, “Behold your mother,” as the institution by Christ of Mary’s spiritual motherhood in relation to all the disciples. This reading was taken up by Ambrose, Augustine, and, in a systematized form, by Saint Bernard of Clairvaux in the twelfth century. Paul VI, in closing the third session of the Second Vatican Council (November 21, 1964), solemnly proclaimed Mary Mater Ecclesiae, ratifying this tradition in the contemporary Magisterium.

The image of Our Lady Mater Populi Fidelis

The devotion to the Mater Populi Fidelis found its most venerated iconographic expression in the image present in the Church of Santa Maria in Aracoeli, on the Capitoline Hill in Rome. This image, of Byzantine tradition, shows Mary in a frontal position with the Child Jesus in her arms, the iconographic typology of the Hodegetria (she who points out the way). Pope Francis, on several occasions, visited this image to entrust to the Virgin the intentions of the Church. The form of papal veneration of this Roman image continues the centuries-old tradition of the bishops of Rome of placing the great ecclesial decisions under Mary’s protection.

In Peru, there is an image of great popular devotion also called Mater Populi Fidelis, identified with Our Lady of Sorrows. The Marian cult in this region of South America integrates the dimension of compassion (Mary by the Cross, Stabat Mater) with that of intercession before her Son for the suffering Church, a synthesis of the two dimensions of the title: sorrowful mother and interceding mother.

Mater Populi Fidelis and Marian ecclesiology

Lumen Gentium, chapter VIII (nn. 52-69), is the fundamental magisterial text for understanding the relation between Mary and the Church. The Council affirmed that Mary is “a most eminent and altogether singular member of the Church, her type and most excellent model in faith and charity” (LG 53). This formulation, Mary as type of the Church, is the point of articulation between Mariology and ecclesiology: the Church is what Mary is in her singular fullness, and Mary is the mirror in which the Church sees her eschatological destiny.
