Let’s say, for argument’s sake, that you have something to share that is not the normal biblical sermon. Perhaps you have an announcement to make, a vision to cast, an update on the new building project, some other leadership issue to address. Even though you are in church, don’t automatically attach a Bible text.
Typically, if not always, there will be a biblical basis for what is being communicated or done. It is obviously fine to share that, but make it clear that is not an authoritative warrant for the action. For example, you can present a biblical basis for fellowship, but don’t leverage that biblical content to add pressure for attending a church social event. There are biblical examples of God’s people working together on a building project, but that is not divine pressure for your people to sign up to the current project. It is fine to give some biblical support, but evaluate if it is really fair and helpful.
Don’t automatically attach a Bible text. Just because you’re in church doesn’t mean every announcement has to be “sanctified” in this way. Let people evaluate what they hear on its own merits, not with the unnecessary pressure of apparent biblical warrant. This is not a hard and fast rule, it’s a judgment call. If the church is following through on church discipline, I would strongly suggest you do give a biblical explanation for the procedure. But for a social event, just take the pressure off and let them choose!
