And in the same region there were shepherds out in the field, keeping watch over their flock by night.9 And an angel of the Lord appeared to them, and the glory of the Lord shone around them, and they were filled with great fear.10 And the angel said to them, “Fear not, for behold, I bring you good news of great joy that will be for all the people.11 For unto you is born this day in the city of David a Savior, who is Christ the Lord.12 And this will be a sign for you: you will find a baby wrapped in swaddling cloths and lying in a manger.”13 And suddenly there was with the angel a multitude of the heavenly host praising God and saying,
14 “Glory to God in the highest, and on earth peace among those with whom he is pleased!”
15 When the angels went away from them into heaven, the shepherds said to one another, “Let us go over to Bethlehem and see this thing that has happened, which the Lord has made known to us.”16 And they went with haste and found Mary and Joseph, and the baby lying in a manger.17 And when they saw it, they made known the saying that had been told them concerning this child.18 And all who heard it wondered at what the shepherds told them.
John 1:1-4, 14
In the beginning was the Word, and the Word was with God, and the Word was God.2 He was in the beginning with God.3 All things were made through him, and without him was not any thing made that was made.4 In him was life, and the life was the light of men.
14 And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth.
This, from Westminster Abby, is a rich high church celebration of this invitation to worship Christ the Lord.
