I believe I can speak to this situation, since I had a very similar experience. In 2007, I was appointed to a divided congregation. We only had one service, at 10:30 AM, and tired to mix traditional music with contemporary.Not long after I came, members of the church and pastor's council began to lobby for a return to Sunday night services. The proponents of this move assured me that everyone wanted to have evening services, so I agreed. Big mistake. Only about 25-30% of the people came back for evening service. Musicians wouldn't come back. Sound people wouldn't come back. Praise Team members wouldn't come back. I never knew who, or what I was going to have, in order to execute the worship service. Interestingly, some of the loudest proponents, were the most lax in their attendance.I think resuming Sunday night is a mistake, based on my direct experience.If you are lucky, 30% of your congregation will come back. With that number in mind, consider:1. The church will have to run power, water, heat/air, etc.2. The church will have to be staffed (music, sound, nursery, ushers)3. You will have to prepare another sermon4. What will that evening service accomplish?To me....I said to ME.....Its likely that those who attend Sunday pm service are already saved. They are probably well established Christians. They probably went to the morning service. That is a lot of effort, just to preach to the choir. I've heard every reason in the book, to have Sunday night and none of them hold water:We might get some visitors (Not likely on Sunday night)We might get some people, whose churches don't have Sunday PM (Uh...No, those folks are on the lake)Remember the Sabbath day and keep it holy (Really? What'd you do from 1:00-5:30)Look, I know anything is possible. But clearly you don't feel good about resuming pm service. My suggestion? Make Sunday night a prayer service. No singing. No devotion. Just prayer. After a month, see what the evening attendance is
