The song of Mary (Luke 1:46-55) is the oldest Advent hymn. It is the most passionate, most vehement, one might say, most revolutionary Advent hymn ever sung. It is not the gentle, sweet, dreamy Mary that we so often see portrayed in pictures, but the passionate, powerful, proud, enthusiastic Mary, who speaks here. None of the sweet, sugary, or childish tones that we find so often in our Christmas hymns, but a hard, strong, uncompromising song of bringing down rulers from their thrones and humbling the lords of this world, of God’s power and of the powerlessness of men. These are the tones of the prophetic women of the Old Testament: Deborah, Judith, Miriam, coming alive in the mouth of Mary.Mary, filled with the Spirit and prepared. Mary, the obedient handmaid, humbly accepting what is to happen to her, what the Spirit asks of her, to do with her as the Spirit will, speaks now by the Spirit of the coming of God into the world, of the Advent of Jesus Christ. She knows better than anyone what it means to wait for Christ. He is near to her than to anyone else. She awaits him as his mother. She knows about the mystery of his coming, of the Spirit who came to her, of the Almighty God who works his wonders. She experiences in her own body that God does wonderful things with the children of men, that his ways are not our ways, that he cannot be predicted by men, or circumscribed by their reasons and ideas, but that his way is beyond all understanding of his own will.
