Is there ever a right time to give announcements during a worship service?
Whenever you do them, announcements feel awkward. They interrupt the flow of worship. They inject mundane matters like church potlucks into the middle of praising God for his holiness and grace.
So where do you put them? This is certainly a judgment call—there’s no biblical teaching on this. And every place has certain advantages and disadvantages. That said, placing announcements at the very beginning of the service, even before the call to worship, seems to least disrupt the service.
