Papal teaching for today

Traditionally, Saturday is devoted to the Blessed Mother, and therefore our Papal teaching for today concerns Mary  The following is taken from the Apostolic Exhortation "Marialis Cultus" of Pope Paul VI, promulgated in 1974 (full text here):

Mary is also the Virgin-Mother-she who "believing and obeying...brought forth on earth the Father's Son. This she did, not knowing man but overshadowed by the Holy Spirit."(52) This was a miraculous motherhood, set up by God as the type and exemplar of the fruitfulness of the Virgin-Church, which "becomes herself a mother.... For by her preaching and by baptism she brings forth to a new and immortal life children who are conceived by the power of the Holy Spirit and born of God."(53) The ancient Fathers rightly taught that the Church prolongs in the sacrament of Baptism the virginal motherhood of Mary. Among such references we like to recall that of our illustrious predecessor, Saint Leo the Great, who in a Christmas homily says: "The origin which (Christ took in the womb of the Virgin He has given to the baptismal font: He has given to water what He had given to His Mother-the power of the Most High and the overshadowing of the Holy Spirit (cf Lk. 1:35), which was responsible for Mary's bringing forth the Savior, has the same effect, so that water may regenerate the believer."(54) If we wished to go to liturgical sources, we could quote the beautiful Illatio of the Mozarabic liturgy: "The former [Mary] carried Life in her womb; the latter [the Church] bears Life in the waters of baptism. In Mary's members Christ was formed; in the waters of the Church Christ is put on."(55)
