Agreed, however the Church at Corinth was not a mission condition.
The entire reference point of Paul was about languages and foreign dialects/languages also in the assembly.
The entire reference point of Paul was about languages and foreign dialects/languages . It has it foundation in Isaiah 28 and has to do with atheist Jews who refuse to hear the gospel. Like Cain in Genesis or Easu who saw no value in the things not seen . They made a mockery of the word of God over and over . God with stammering lips (mocking deriding) Sent as sign to confirm their unbelief (No faith ).
Once the sign is confirm as to who and what it points to .Then its smooth sailing the rest of the doctrine will fall into place.
A say the sign confirms unbelief(no faith ) What do you say .and not what do other say? Make the foundation of tongues of no effect?
