Multitudes of angels assist at every Mass. St. Gregory: "The heavens open and the multitudes of angels come to assist at the Holy Sacrifice." St. Augustine: "The angels surround and help the priest when he is celebrating Mass." St. John Chrysostom: "When Mass is being celebrated, the Sanctuary is filled with countless angels who adore the Divine Victim immolated on the altar."

The efficacy of the Mass is so wonderful, God's mercy and generosity are then so unlimited that there is no moment so propitious to ask for favors as when Jesus is born on the altar. What we then ask for we shall almost certainly receive, and what we do not obtain in the Mass we may scarcely hope to receive by all other prayers, penances or pilgrimages. The angels know this full well and come in multitudes to adore God and make their petitions at this hour of mercy. What an example for us!

We read in the revelations of St. Bridget: "One day, when I was assisting at the Holy Sacrifice, I saw an immense number of holy angels descend and gather around the altar, contemplating the priest. They sang heavenly canticles that ravished my heart; Heaven itself seemed to be contemplating the great Sacrifice. And yet we poor blind and miserable creatures assist at the Mass with so little love, relish and respect!" Oh, if God would open our eyes, what wonders should we not see!
