(b) In a congregation, only two or three people at most should speak in tongues (1 Cor. 14:27), and each must speak in turn. This is the case even though there may be hundreds or even thousands of people in a church. The many Protestant churches that call upon many people, even hundreds during a service, to speak in tongues contravenes Paul’s divine mandate, and raises doubts about its authenticity.
(c) The tongue-speaking must be done for the edification of the Church (1 Cor. 14:5,26). Paul says that a person who speaks in tongues edifies himself (1 Cor. 14:4) which is good, but Paul also says tongues must edify the Church. This is why Paul requires one to interpret the tongue, and why Paul says only two or three at the most should speak in tongues during an assembly. A mass proliferation of tongue-speaking in an assembly would lead to confusion. This would not be of divine origin because Paul says, in connection with tongue-speaking, that God is not the author of confusion (1 Cor. 14:33).
(d) After setting the parameters of tongue-speaking and warning against avoiding confusion, Paul says that “women should keep silence in the churches. For they are not permitted to speak but should be subordinate, even as the law says” (1 Cor. 14:34). This means that women are not allowed to speak in tongues in church. Paul is underscoring that this is a divine command from God when he ends his statement with “even as the law says.” Again, many Protestant churches contravene this divine command by allowing women to speak “in tongues” in their assemblies.
(e) Paul teaches that a proliferation of tongue-speaking in a church may actually be a sign of unbelief and God’s ensuing judgment upon them. When Paul teaches the Corinthians about the proper use of tongues (1 Cor. 14:21), he quotes from Isaiah 28:11-12: “By men of strange tongues and by the lips of foreigners will I speak to this people, and even then they will not listen to me, says the Lord.” Paul’s use of Isaiah is significant because he is referring to the apostate Jews of the 8th century right before they were destroyed by the Assyrians. To punish the Jews, God first allowed the Assyrians to speak in foreign tongues to them to confuse them before they were ultimately destroyed. God’s judgment being revealed in the form of foreign tongues was first prophesied to Israel in the 15th century, B.C. (see Deut. 28:49-50). Remember also how God sent unintelligible tongues to punish His people for their lack of faith at the tower of Babel (Genesis 11).
