CCC 333 From the Incarnation to the Ascension, the life of the Word incarnate is surrounded by the adoration and service of angels. When God “brings the firstborn into the world, he says: ‘Let all God’s angels worship him.’”1 Their song of praise at the birth of Christ has not ceased resounding in the Church’s praise: “Glory to God in the highest!”2 They protect Jesus in his infancy, serve him in the desert, strengthen him in his agony in the garden, when he could have been saved by them from the hands of his enemies as Israel had been.3 Again, it is the angels who “evangelize” by proclaiming the Good News of Christ’s Incarnation and Resurrection.4 They will be present at Christ’s return, which they will announce, to serve at his judgement.5
CCC 530 The flight into Egypt and the massacre of the innocents6 make manifest the opposition of darkness to the light: “He came to his own home, and his own people received him not.”7 Christ’s whole life was lived under the sign of persecution. His own share it with him.8 Jesus’ departure from Egypt recalls the exodus and presents him as the definitive liberator of God’s people.9
