I hear that a number of churches - mostly large, evangelical types - are not holding any services on Christmas Sunday, the main reason given that families can spend time together. So, using that logic, why should there be any church meetings on any other Sunday of the year? After all, family time is important all year round.
I find this decision sad (fortunately my church is still meeting). If there were ever a day were one ought to make a little effort to get dressed and go worship the Lord in a formal-church-sort-of-way, then Christmas would be it! Basically, I guess people just don't want to tear themselves away from the presents for any amount of time.
