My husband was preaching Sunday morning from Philippians on what may have been an early Christian hymn about the Incarnation (Christmas). Paul quotes it as if it is a familiar song or reading. Maybe he was a little like Charles in that he would break into song during his sermons too. ;) They really didn't celebrate Christmas yet, but they certainly did know what it was all about.
A Christmas Card from Philippi:
1If you have any encouragement from being united with Christ, if any comfort from his love, if any fellowship with the Spirit, if any tenderness and compassion, 2then make my joy complete by being like-minded, having the same love, being one in spirit and purpose. 3Do nothing out of selfish ambition or vain conceit, but in humility consider others better than yourselves. 4Each of you should look not only to your own interests, but also to the interests of others.
5Your attitude should be the same as that of Christ Jesus:
6Who, being in very nature God,
did not consider equality with God something to be grasped,
7but made himself nothing,
taking the very nature of a servant,
being made in human likeness.
8And being found in appearance as a man,
he humbled himself
and became obedient to death—
even death on a cross!
9Therefore God exalted him to the highest place
and gave him the name that is above every name,
10that at the name of Jesus every knee should bow,
in heaven and on earth and under the earth,
11and every tongue confess that Jesus Christ is Lord,
to the glory of God the Father.
12Therefore, my dear friends, as you have always obeyed—not only in my presence, but now much more in my absence—continue to work out your salvation with fear and trembling, 13for it is God who works in you to will and to act according to his good purpose.
14Do everything without complaining or arguing, 15so that you may become blameless and pure, children of God without fault in a crooked and depraved generation, in which you shine like stars in the universe 16as you hold out the word of life—in order that I may boast on the day of Christ that I did not run or labor for nothing.
