LadyWiz,
We start at 10 and we're done by 12. Also insert a welcome/fellowship between praise & worship and announcements. Pastor doesn't believe it takes all day. Sunday, we could have gone like that though!
At my last church we started at 1245am and ended by 2 to 2:15pm!
We had cut out things like announcements, and just placed them on the bulletin board. The message was usually about 30-40 minutes.....
....but back in Detroit, we'd be in church all day, literally, especially if you were a musician. Your church may have dismissed, but most likely, you'd go to one of your friend's churches. I know I did at least. I always like the late services the most, between 7pm and 11pm.
