Curtis, unless what they are talking about is someone teaching/preaching to believers with a different language. It would be like an American church today saying we are not going to allow an evangelist from Mexico who only speaks Spanish to preach at our church which would require an interpreter.Tongues are not required for salvation but they are a sign that follows those who believe, per Mark 16.
The personal prayer language unknown tongue is for all believers.
The specialized gift of speaking in tongues aloud in church with a message from God, is not for everyone.
Tongues spoken aloud in church were not known languages, but unknown languages that need interpreted by someone with the HS gift of interpretation.
If tongues in church were known languages, that would mean that when the Corinthian church forbade tongues, they forbade speaking in a known language - which would mean a VERY silent church service!
Paul tells us in 1 Corinthians 14:11that he does not know the meaning of the language I shall be a foreigner to that person and that person who speaks will be a foreigner to him.
I think many choose to brush aside, to ignore 1 Corinthians 14:2 For he who speaks in a tongue does not speak to men but to God, for no one understands him; however, in the spirit he speaks mysteries. This would mean that someone speaking in an unknown utterance in Church is speaking TOO GOD.
1 Corinthians 14 is very interesting. Things can be understood in various ways mostly dependent on how YOU WANT to understand. We all have our bias for whatever reason. What I come away with in regard to the gift of Tongues is that its languages and prayer language. Tongues are valid today. Prayer language/utterances are valid today BUT some have elevated their role in salvation and are fixated on that one gift of many. Others are fixated on healing ministry the same way. Churches fail to teach the full Gospel to their members. A Spirit inspired message from the pulpit is wonderful but I think a Spirit inspired expository teaching of the scriptures are just as important. Pastors ignore scripture that might raise questions of conflict with denominational beliefs. Paul clearly seems to diminish the gift of Tongues in 1 Corinthians 14:19-23.
Its difficult for me to ignore all the scriptures about how someone willfully committing sin, convincing themselves they are not in sin, when God says they are a liar. That God is not in them. Does it make any sense that a prostitute practicing her trade is at the same time a temple of the Holy Spirit? Can someone who is filled with the Holy Spirit (sealed with the Holy Spirit) sleep with prostitutes on Saturday and speak in Tongues from a pulpit on Sunday and repeat that many many times? What Spirit did he have? A Pastor friend told me we should not attempt to reconcile that behavior from Jimmy Swaggart. I can't reconcile it and I can't understand it either. Is the Holy Spirit jumping in and out of us based upon our behavior? Is speaking in an unknown tongue really any evidence at all? What evidence was it for Jimmy Swaggart? Bad on Saturday, Good on Sunday. Can tongues be a deception? Some have faked it and admitted it later. Repeating "I ride a Honda" over and over very fast. It would be interesting to do some research in Jimmy Swaggart's tongues and interpretations during that period.
