I find your response interesting but not fully founded in truth. I am saying that respectfully. Yet you do have an opinion concerning the "upper Room experience". you said "the vernaculars of Aramaic and Greek, "
Acts 2:5 "
And there were dwelling in Jerusalem Jews, devout men, from every nation under heaven.
If it was not the 120 which I think it was and it was only the 12 that means had to speak more than one languages when we see in scripture approx. 70 were heard. and not all Jews were Hebrew speaking Jews or even Greek they, however, made the journey to Jerselum to visit the temple. which was the reason wht they were there. If you are saying all who speak in tongues was only in Aramaic and Greek , the Acts chapter 2 account is not in agreement with that understanding.
ESV Acts 2:7-11
And they were amazed and astonished, saying, “Are not all these who are speaking Galileans? 8 And how is it that we
hear, each of us in his own native language? 9 Parthians and Medes and Elamites and residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia, 10 Phrygia and Pamphylia, Egypt and the parts of Libya belonging to Cyrene, and visitors from Rome, 11 both Jews and proselytes, Cretans and Arabians—we hear them telling in our own tongues the mighty works of God.”
In addition, the 120 contextually present, supports the job of organizing the newly 300 won to the Lord on that day. were only 12 going to disciple 3000?. Cause and effect.
In chapter 1 verse 14-15 is very telling :
14"14 All these with one accord were devoting themselves to prayer, together with the women and Mary the mother of Jesus, and his brothers.[
c] "
that was more than the 12.
"15 In those days Peter stood up among the brothers (the company of persons was in all about 120) "
Nothing states they left. Nothing states the 120 were not present. that is an assumption.
The last thing I would never record myself. That is immaturity. I disagree with your assertion below
"It’s interesting that many people, when asked to record themselves speaking tongues and then really listen to it, will say that one does not submit a gift of the Spirit to an electronic test. But it must be pointed out that it is not the test that shows what tongues-speech really is, it only confirms it."
The word of God confirms it and the effects AFTER the gift has been used. Did the gift Edify, Comfort, and exhort. Were people saved? doing something to prompt human reasoning is not needed. Nor should one demonstrate a gift to prove naysayers. Jesus never did that for the Pharisees. No test shows any proof of the Holy Spirit done by a secular humanist. Those same types will tell you Jesus did not die or rose from the dead. But just so you know test has been done but not accepted. Those against the gifts of the Holy for today will not and those for the Gifts will.
What did the gift produce ? is the Biblical test. They are languages. There is foolishness too did not see anyone disagree with that.
