if you are interested in the cycle of readings from the common lectionary that many churches throughout the world use their Sunday readings; you can find some commentaries on this website.
They are posted Sunday by Sunday.
Most of us have our own impressions of what Christmas has come to mean in our modern culture. A time of festivity spent with family and friends; a time of goodwill and hopefully, charity. A time of beautiful decorations and colourful lights that lighten the night, of carols both secular and religious. Christmas is also a time for reflection. It is probably in the carols that many of us get a glimpse of the deeper meaning of Christmas. For example, ‘O Little Town of Bethlehem’, just to name one:
“How silently, how silently
The wondrous gift is given
So God imparts to human hearts
The blessings of His heaven
No ear may hear His coming
