Theme: that is pretty obvious, isn't it? :)
Sentence: To you is born this day in the city of Davd, a Saviour, who is the Messiah, the Lord (Luke 2:11).
Collect: (from NZ Lectionary 2017)
God of light and life,
you are born among us as a baby, in the flesh, as one of us.
As we rejoice in our bodies in the beauty of summer
grant that we may also celebrate the wonder of your incarnation
and rejoice in the mystery of God becoming one flesh.
We ask this through our Lord Jesus Christ,
who shares our human nature and'who is alive and reigns with you,
in the unity of the Holy Spirit, one God, now and for ever. Amen.
Readings: [I am just giving one set from the NZ Lectionary]
In this prophecy, as originally given, the hope and expectation concerns restoration of the greatness and supremacy of the Davidic throne.
At the point of writing, Israel's situation is oppressive: note the implicit violence of the language of "yoke," "bar," "rod," and "boots" in verses 4-5.
Verse 4's reference to "Midian" is a recollection of story of Gideon's defeat of Midian (Judges 7:15-25).
Verses 6 onwards celebrate the birth of a new David (perhaps, at the time of writing, the birth of Hezekiah). Christian readers of these verses have read these verses as perfectly correlated with the birth of Jesus and his subsequent growth to be the adult preacher and leader of the Kingdom of God.
This psalm is coherent with the hope and expectation of the restoration of Israel, foreshadowed in the Isaiah reading above.
11: In the life, death and resurrection of Jesus Christ, the grace of God has appeared (been manifested) to the world. "Bringing salvation to all" is enigmatic: does it imply that all will be saved? At the very least it is stating that the salvation the Saviour brings is available to all humanity.
12: The coming of the Saviour (the birth and life of Jesus Christ) and the expectation of his return to earth (v. 13) creates a "present age" in which we (followers of Jesus Christ) need to know how to live. Paul thus speak of the same "grace of God" which has saved us also working within us to train us to "renounce impiety and worldly passions, and in the present age to live lives that are self-controlled, upright, and godly."
13: This training scheme (so to speak) endures "while we wait for the blessed hope and manifestation of the glory of our great God and Saviour, Jesus Christ." Christ is unseen in our midst during this time but we will know when he comes in glory because it will be manifest among us. Note the rare occasion here when Jesus Christ is identified within the New Testament as God.
14: Who is Jesus Christ? Three notable characteristics are mentioned in this verse. First, "who gave himself for us" (see also Galatians 1:4; 2:20; Ephesians 5:2; 1 Timothy 2:6). Christ came for our sakes and in his coming gave himself over to death that we might live. Secondly, "redeem us" or, in the context of Paul's day, buy us out of slavery (to Satan, to sin): see also Romans 3:24; 1 Corinthians 1:30; 6:20; 7:23; Ephesians 1:7; Colossians 1:14; Mark 10:45). Christ gave himself in costly sacrifice that we might be redeemed. Thirdly, "purify for himself a people of his own": see also Deuteronomy 7:6-8; exodus 9:5-16; 1 Peter 2:9. Christ came to restore and enlarge the people of God, according to the promises made long ago to Israel (see above, Isaiah and Psalm readings).
There is a wonderful but quite technical debate within the first few verses of this passage concerning the reference to Quirinius and thus to the time of this registration (census). In short, the debate concerns whether we can match what we know of Quirinius as a Roman official and the time when we think Jesus was born (according to Matthew's chronology which places Jesus' birth before the death of Herod the Great). See here for a discussion of the issues.
What is undebatable is what Luke is attempting in these first few verses. First, he is locating the birth of King Jesus in the world ruled by another king, the Roman emperor Augustus (1). The whole story of Luke-Acts tells us how the king born in Bethlehem, via the preaching of his apostles, became a rival king to the Emperor in Rome itself. Secondly, he is explaining how Jesus of Nazareth (i.e. Jesus who grew up in Nazareth) nevertheless was born in Bethlehem, some distance away (2-4). Thirdly, he is connecting the birth of Jesus as king with the house of David, the greatest King of Israel (4, 11).
Of course for there to be a bay there needs to be a birth, and with the preliminaries of time and place out of the way, we finally read that Jesus is born (6-7). Note how the specific location of his first days/weeks of life "in a manger" is a tiny detail within these verses. Do we make too much of this when we talk much of Jesus being born in a stable, seemly unwanted in the inn? Nevertheless, in a passage mentioning Augustus and David, the reference to Jesus being placed after birth in a feeding trough underlines the obscurity of Jesus' beginning to his life: he is born in Palestine (at the edge of the Roman Empire), in Bethlehem (an insignificant village relative to the great city of Jerusalem) and placed in a manger (outside of ordinary human residency).
Why do we then meet shepherds (8-14) as the first, in Luke's telling, to greet the newborn king? Obviously we must speculate as Luke gives no hints. But shepherds in the context of associating Jesus with King David (the shepherd king) suggests that shepherds are very appropriate as a group to recognise the new Shepherd King Jesus.
They are good shepherds, incidentally, because in the middle of the night they are "keeping watch over their flock" (8) Understandably they are afraid when unexpectedly an angel appears, the glory of the Lord shines around them and they hear a voice (9-10). Everything here, including the fear, is redolent of many instances in the Old Testament when the angel of the Lord appears to a person or a couple or a group. As then so now the first words of the angel are "Do not be afraid" (10). The angel has not come to judge the shepherds but to announce good news to them and to ask them to be part of the celebration of that announcement, which is "good news of great joy for all the people" (10-11).
Verse 11 piles on the titles for Jesus! He is "A Saviour, who is the Messiah, the Lord." With these three titles the angel is saying that the newborn baby is the full fulfilment of all Old Testament prophecies about the one who would come to restore Israel (see, again, our passage from Isaiah above, as one such prophecy). And "Lord" is particularly significant as it equates Jesus with God himself (since the exclusive name of the God of Israel, YHWH, is translated by the same Greek word, kyrios, in the Greek Old Testament).
Verse 12 adds a little to the meaning of the manger. How will the shepherds know where to find this baby? (Remember, no GPS, no cellphones in those days!) Presumably more than one baby was born at that time. But only one had been placed in a manger. The others would have been in their cots and cribs in their homes. A few questions in the nosy, gossipy community of Bethlehem and the shepherds would have easily found the baby-in-a-manger.
With a final burst of song, verses 13-14, the angels were gone and the shepherds were on their way to Bethlehem (15). But what a burst of song it was. What would we give in the world today for the simple matter of "peace"?
