If the Gospel is not Good News to the poor, the oppressed, the prisoner, the lowly, the least, the last, the lost, the rejected, the marginalized, the asylum seeker, then it is not the Good News Mary proclaimed.
If the Gospel is not a warning to the rich, the powerful, the mighty, those with influence, the privileged, then it is not the Good News of which Mary sang.
If the Gospel is not also a promise to deliver the rich from the prison of wealth, the powerful from the temptations of dominance, the mighty from their abilities to lord it over others, the influencers from their pride, and the privileged from the captivity of their status, then it is not the Good News that Mary embraced.
If the deliverance spoken by Mary is purely spiritualized to refer only to saving the human soul, then it is not the salvation of which Mary speaks. Mary's song is not a heavenly-minded refrain that does no earthly good. It shouts the arrival of the coming upheaval that God had long promised to bring to the world.
