What must Mary have felt as she heard from the mouth of Peter, John, James and the other Apostles the words spoken at the Last Supper: “This is my body which is given for you” (Lk 22:19)? The body given up for us and made present under sacramental signs was the same body which she had conceived in her womb! For Mary, receiving the Eucharist must have somehow meant welcoming once more into her womb that heart which had beat in unison with hers and reliving what she had experienced at the foot of the Cross.
57. “Do this in remembrance of me” (Lk 22:19). In the “memorial” of Calvary all that Christ accomplished by his passion and his death is present. Consequently all that Christ did with regard to his Mother for our sake is also present. To her he gave the beloved disciple and, in him, each of us: “Behold, your Son!”. To each of us he also says: “Behold your mother!” (cf. Jn 19: 26-27).
Experiencing the memorial of Christ's death in the Eucharist also means continually receiving this gift. It means accepting – like John – the one who is given to us anew as our Mother. It also means taking on a commitment to be conformed to Christ, putting ourselves at the school of his Mother and allowing her to accompany us. Mary is present, with the Church and as the Mother of the Church, at each of our celebrations of the Eucharist. If the Church and the Eucharist are inseparably united, the same ought to be said of Mary and the Eucharist. This is one reason why, since ancient times, the commemoration of Mary has always been part of the Eucharistic celebrations of the Churches of East and West.
