It's one thing for an individual to decide that he's going to sleep in on Sunday/Christmas or open his presents, and just go to the Saturday service instead or not go at all. That is his individual decision and affects only him.
But when the church decides to close on Christmas, it affects every single parishioner. Even if they had made a personal, individual decision to attend on Christmas Day.
Doesn't directly concern us Catholics of course, because Mass is celebrated 24/7/365, whether anybody shows up or not. We had a really bad ice storm last winter, roads were bad and power was out at the church. My husband sees any snow and ice as a personal challenge, so he and my son went to church anyhow (daughter and I were out of town.)
It was a tiny service, maybe 10-20 people there out of a very large parish. The folks who were there organized to act as altar servers, scratch up a (a capella) choir, and get the job done. It was a heart-warming event. But even if nobody at all showed up the priest would have celebrated Mass anyway.
Maybe part of the disconnect with all of this is that Protestant pastors tend to be married and have family of their own.
I don't have a problem with churches closing on Christmas, especially if they are having lots of services on Christmas Eve. I figure the pastors and their families are doing their duties the day before. I'm sure it is well-publicized.
My church is small and meets in a school. For 2 summers, we've had to be very creative about church while the school was unavailable due to contruction. It gives you a whole new perspective about what church is.
Some people would have a hard time meeting in a school because because they care more about the building than about the people. However, my husband and I think the church is more about the people than the location or the time.
