Why we can't cancel the Service on Sunday to be service on Sunday?

Let's just have some fun with this one. Why can't we cancel the service (serve-us) on Sunday to be service on Sunday? Instead of going to church certain times a year -cancel the service and be the church service in the community by serving on Sunday. I'm not recommending that we cancel the Sunday service every week. I'm not saying the Sunday service is a bad thing. I'm not saying that it is either or. But let's set it up. Let's say some leaders or members wanted to cancel the Sunday service in order the be Sunday service to show the community who Jesus is as the one who cares for widows, orphans, the poor or those who just need Him, then what?

What would the "members & pastors" say are the reasons" they cannot cancel the Sunday service to be service on an occasional Sunday? I'll offer the obvious and you can add to the list.

1) Pastor's would fear being crucified by the members..
2) Members would dig in and if there is no service to attend there will be no service either.
3) Pastors would fear they would be labeled as un-spiritual for suggesting such a thing.
4) How could we pay for the buildings, salaries and programs. One missed offering will cripple.
5) The choir can't sing.
6) What would the community think?
7) What if a visitor shows up and we our service is closed?
8) What would we do, where would we go, how do we find those in need?
9) Some of our people will go to other services if we do service.

Where I have pastored (Illinois/Indiana) we got allot of snow. When it snowed all ears were glued to the radio. As churches would start closing - I was always among the last to call off the service. Because of that, the phones would ring off the hook and people would tell me about all the larger churches that cancelled service. It was odd to me that a few stood with me in holding out but the majority was happy when I finally called it off.

We can cancel the Sunday service for other reasons but never so that the church can be service on Sunday?

What other reasons can you add - Why we can't cancel the Sunday service to be service on Sunday?
