The man Friday night “spoke in tongues” twice.
If anyone speaks in a tongue, it should be by two or at the most three, and each in turn, and one must interpret; 28 but if there is no interpreter, he must keep silent in the church; and let him speak to himself and to God. 1 Cor. 14:27-28
False teachers want us to think that they are filled with the Holy Spirit. How could the Holy Spirit give them power to do something against His own Word? When they do this, they write in capital letters that they are at best disinterested in obedience, and at worst they actively disregard it. And if they can blatantly step over the clear statements of Scripture, wherein do they prove themselves Christians at all?
Tongues in a setting like this is one more mark of entertainment. The music, the clothing, the language, and the theme all bespeak entertainment. Speaking in tongues is just one more added trick.
