58. In the Eucharist the Church is completely united to Christ and his sacrifice, and makes her own the spirit of Mary. This truth can be understood more deeply by re-reading the Magnificat in a Eucharistic key. The Eucharist, like the Canticle of Mary, is first and foremost praise and thanksgiving. When Mary exclaims: “My soul magnifies the Lord and my spirit rejoices in God my Saviour”, she already bears Jesus in her womb. She praises God “through” Jesus, but she also praises him “in” Jesus and “with” Jesus. This is itself the true “Eucharistic attitude”.
At the same time Mary recalls the wonders worked by God in salvation history in fulfilment of the promise once made to the fathers (cf. Lk 1:55), and proclaims the wonder that surpasses them all, the redemptive incarnation. Lastly, the Magnificat reflects the eschatological tension of the Eucharist. Every time the Son of God comes again to us in the “poverty” of the sacramental signs of bread and wine, the seeds of that new history wherein the mighty are “put down from their thrones” and “those of low degree are exalted” (cf. Lk 1:52), take root in the world. Mary sings of the “new heavens” and the “new earth” which find in the Eucharist their anticipation and in some sense their programme and plan. The Magnificat expresses Mary's spirituality, and there is nothing greater than this spirituality for helping us to experience the mystery of the Eucharist. The Eucharist has been given to us so that our life, like that of Mary, may become completely a Magnificat!
