Here's the beautiful Introit Gaudeamus in omnes Domino for today's Mass:
Translation: Let us all rejoice in the Lord , celebrating a festival day, in honor of all: at whose solemnity the Angels rejoice, and give praise to the Son of God. In the Lord, O ye just: praise becometh the upright. Glory...
And this excerpt from a sermon of St. Bernard comes from today's Office of Readings:
"Come, brothers, let us at length spur ourselves on. We must rise again with Christ, we must seek the world which is above and set our mind on the things of heaven. Let us long for those who are longing for us, hasten to those who are waiting for us, and ask those who look for our coming to intercede for us. We should not only want to be with the saints, we should also hope to possess their happiness. While we desire to be in their company, we must also earnestly seek to share in their glory. Do not imagine that there is anything harmful in such an ambition as this; there is no danger in setting our hearts on such glory."
And to spur us on, here's Fra Angelico's beautiful painting of the forerunners of Christ with the saints and martyrs.
