The Church asks us to understand that Christ, who came once in the flesh, is prepared to come again. When we remove all obstacles to his presence he will come, at any hour and moment, to dwell spiritually in our hearts, bringing with him the riches of his grace.
In her concern for our salvation, our loving mother the Church uses this holy season to teach us through hymns, canticles and other forms of expression, of voice or ritual, used by the Holy Spirit. She shows us how grateful we should be for so great a blessing, and how to gain its benefit: our hearts should be as much prepared for the coming of Christ as if he were still to come into this world.
-Saint Charles Borromeo
