That is highly unusual if your hall only has 1 Congo.
Yes, I wonder what the reasoning was?
The first problem is when do you eat lunch? Early beforehand or later afterwards?
Secondly, it would seem that your Body of Elders have effectively killed off the Sunday Ministry for all apart from the uber-zealous
When do they expect the publishers to go out on the minstry on a Sunday?? I suspect from your description that your terittory AND publishers are spread out.
Ministry before the meeting is a push, particuarly if you're starting later on a Sunday and there's limited time in order to then have food (?) and actually get to the meeting - at least 20 minutes before it starts of course
Ministry afterwards is a killer - and rememeber you should associate after meeting, not rush off, and MSs have jobs to do, besides, again, when are you gonna eat? Even sandwiches need a time and place.
If you are the only congregation using the Hall, unless your Elders have an extremely good reason, I suspect the CO will make them go back to 10am.
Of course, your Elders might be trying to kill off Sunday Ministry anyway
And attendance... how far away is the next nearest Hall with a 10am meeting??
