“In perfect love this law holds: that the lover become like the one he loves.”While the Council Fathers at Ephesus reflected on the mystery of the Incarnation, they were led inevitably to this paradox: the God of eternity has a human mother, and her name is Mary. Mary of Nazareth hasn't simply "left a legacy" or "made a mark." In her humility, she won’t boast in her own actions, her own choices. Nevertheless, we call her “blessed,” because her participation in God's saving plan has decisively changed humanity forever. She was offered a unique role in God's saving union with humanity and with creation: to give God his human face, and his human life. To that offer, she simply said, “Here am I, the servant of the Lord; let it be with me according to your word” (v. 38). “All generations will call me blessed.” As we know, the Spirit of God has ensured that this exclamation of the Mother of God would come true. Thanksgiving for Mary's unique role began with the Scriptural origins of the Church, such as in the accounts of her and the Beloved Disciple at the foot of the cross (John 19:26), her presence with the Apostles after the Ascension and at Pentecost (Acts 1:14), the image of the crowned woman in Revelation 12:1, and, indeed, St. Luke's intentional inclusion of her Song of Praise in his Gospel account. On this Third Sunday of Advent, portions of this Song of Mary – known as the Magnificat for its opening word in Latin – take the place usually given to a Psalm of David. For much of the history of the Western Church, the Magnificat has found its place on the lips of clergy and religious in their daily recitation of Vespers or Evening Prayer. It's had a particular influence in the English-speaking world, since it forms the centrepiece of the Anglican service of Evensong. That service, so prevalent throughout the modern era and now part of the Roman Catholic liturgical family through the Ordinariates, has received its fair share of magnificent choral settings over the last few centuries. Here’s an early example of a setting by William Byrd, a distinctive composer who navigated both sides of the English Reformation: From the moment that Mary of Nazareth uttered her Song of Praise to today, all generations have truly called her "Blessed."
