From Anglican Mainstream.
The earlier antiphons have already alluded to the Messiah coming not only to Israel but to convert the gentile nations and breaking down all barriers to the freedom and peace that he is. While the Messiah is the cornerstone on whom our spiritual foundations are laid, we are reminded today that there are other examples of faith from unlikely sources like the women of Galilee in the person of Mary and Elizabeth who are persons of great faith. The canticle they pray gives us a sense of what Kingdom this King of the Gentiles is going to establish.
