From this week's readings in the Treasury of Daily Prayer:
...As an entire race is brought to honor by a marriage, so the marriage of the Son of God with humanity has restored the human race to honor (Matt. 22:2), What wonder, then, that the angels serve us, since the Son of God, the Lord of the angels, came to earth that He might serve us? - Johann Gerhard
This made me think about someone of low social standing "marrying up" - which is a small picture of what happens with the lowly church and her glorious bridegroom, the Christ!
