The Divine Maternity of MaryWhen Mary of Nazareth conceived in Her womb the Word of God, that conception was the effect of the fullness of Her grace, and of an action of the Holy Spirit which occurred in Her soul first of all, thereby making of Her flesh a tabernacle and a sanctuary. The dignity of the Mother of God is Her great sanctity, it is the incomparable grace which raises Her above all the Angels, the grace in which She was predestined and created for this glorious purpose. By the acts of Her blessed Maternity, She bordered on divinity while remaining entirely human. In this way She seems to exhaust, as it were, the power of God — the fullness of the grace accorded Her cannot be surpassed. It is easier for us to conceive of the greatness of Mary, however, when we consider Her maternity of the Mystical Body, the Church, which like Herself is entirely human, and composed of persons who are very far indeed from being what our Saviour was, a Divine Person incarnate.
