I still celebrate Christmas the way I was brought up to celebrate it.
I do not believe that Jesus was born on that particular day, but I still
enjoy the Christmas music that is played at that time. It is special music.
I still enjoy buying presents, and putting them under a tree,(real or
artificial) makes no difference to me, and hanging up all of the lights
and decorations, (it may be pagan in origin) but I think that they are
pretty. I still like to send cards to my friends, and to receive them as
well.
 
I have studied Jewish traditions and feast days, but I was not born
into a Jewish family, so I do not feel like I should celebrate these
days. I think that having the knowledge of what they mean is
enough. Jesus told the Samaritan woman that someday people
will worship God in spirit and truth. Not in a particular place, or
in a particular way.
 
I think that the celebration of Christmas is a good way for
Christians to spread the gospel to an unbelieving world. The
atheists want to stamp out Christmas, and it's traditions for
that very reason. The gospel can be told to people at that time,
because the story of the birth of Jesus is everywhere you turn.
Anytime Jesus is glorified, it is good. Whether it is through a
pagan tradition, or through the church itself. Christmas may be
the only time some people ever hear the story of Christ.
