It seems to me that this Holy Day should be set aside for the church family to gather and worship the birth of the King. Yet search a bit and you will see that the very WELS churches that don't admit they are Lutherans are the same ones following the evengelical trend of not having a worship service on Christmas Day. They love the pregame Rock show on Christmas eve but don't show up for the actual event on Christmas Day.
Heb. 10.25 "Let us not give up meeting together, as some are in the habit of doing, but let us encourage one another-- and all the more as we see the Day approaching."
These Rock and Roll churches of course balk at the liturgy and the liturgical calendar. They scream we don't have to go to church on Christmas. We don't have to use the liturgy. We don't have to follow the liturgical calendar. Again the identity of the Lutheran church is lost as they follow the trend of the non-demonational church down the road.
