It is helpful to recall that we do not have a journalist’s account of this meeting. Rather Luke, speaking for the Church, gives a prayerful poet’s rendition of the scene. Elizabeth’s praise of Mary as “the mother of my Lord” can be viewed as the earliest Church’s devotion to Mary. As with all authentic devotion to Mary, Elizabeth’s (the Church’s) words first praise God for what God has done to Mary. Only secondly does she praise Mary for trusting God’s words.
Then comes the Magnificat (Luke 1:46-55). Here, Mary herself—like the Church—traces all her greatness to God.
Reflection
One of the invocations in Mary’s litany is “Ark of the Covenant.” Like the Ark of the Covenant of old, Mary brings God’s presence into the lives of other people. As David danced before the Ark, John the Baptist leaps for joy. As the Ark helped to unite the 12 tribes of Israel by being placed in David’s capital, so Mary has the power to unite all Christians in her son. At times, devotion to Mary may have occasioned some divisiveness, but we can hope that authentic devotion will lead all to Christ and therefore, to one another.
