1 Corinthians 14:37-40

1Co 14:37 If anyone considers himself a prophet, or spiritual, he should really know that the things I am writing to you are a command of the Lord,
1Co 14:38 but if anyone ignores them, he should be ignored.
1Co 14:39 So then, brothers, seek to prophesy, and do not prevent speaking in other languages.
1Co 14:40 But all these things should be done properly and tactfully.

properly and tactfully

The minor theme of disorder in the public worship (which Paul had been addressing since chapter 11) is now seen to be a part of the major theme in 1 Corinthians: divisions caused by idolising leaders. Some of the leaders of the Corinthian congregations were actually ringleaders in the circus. That is, they were the cause behind all these confusing assemblies. They would not be inclined to obey Paul’s commands (which came from the Lord himself). So, Paul says, if you have a leader who chooses to ignore this sound advice, that leader himself should be ignored. Public worship needs to be done properly and tactfully (kata taxin), and anyone demanding confusion and disorder is not doing so as a true prophet of God, and cannot blame the Holy Spirit, because disorder is not spiritual.

LORD, as leaders, may we lead your church faithfully, and lead others to worship you properly and tactfully.
