I’ve been to churches where the order of service hadn’t changed in decades. There’s an unspoken rhythm to worship in such a church that’s calming in its predictability. Having a worship structure set in stone means worshipers don’t expend mental energy following a new order of worship; they can just focus on the service. But that same predictability can also make the service rote or boring.
I’ve also attended a church whose service never seemed to be the same from week to week. The service would start a few minutes late as people filtered in; the worship band would sing three songs or five and the pastor took as much or as little time as he wanted to deliver his sermon. Sometimes the service would make you miss lunch appointments; other times, you found yourself with an extra 20 minutes after the service.
What about your church? Does your church follow a strict order of worship or does it change things weekly?
