After the Mass, we pray the Angelus (or, from Easter to Trinity Sunday, the Regina Coeli). This prayer expresses our devotion to Mary, the mother of God, and reflects on the Incarnation of Christ at the Annunciation—that profoundly holy moment in which the Angel Gabriel announced God’s invitation for Mary to be the mother of the Messiah, and she said yes. When the Angelus is prayed by more than one person, a leader says the first part, with everyone else reciting the responses.
