I support the biblical account as the authorial intent meant it to be. Acts 1:8 and then manifested in Acts 2: 1-38 was a miracle and a birth of the church. Tongues was used as a sign as it is stated in 1 cor 14:22 the also mocked tongues that day too. you can read that in Acts 2:13 " Others mocking said, These men are full of new wine."
they did not understand what was happening .
This was somewhat the case in the Corinthian church as we read 1cor 12, 13, 14. This is why Paul addressed the misuse of the gifts. as far as supporting human languages can you tell me how many languages were spoken on the " Day of Pentecost" in acts 2? Some slipt hairs saying they spoke and the hearing of those was the miracle like it was transformed into languages they( the hears) understood . All I know is the bible says they spoke acts 2:4 "And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance."
and they ( the hearers) heard acts 2:6 " Now when this was noised abroad, the multitude came together, and were confounded, because that every man heard them speak in his own language."
I am not going to try an explain to you this wonderful working of God however, it is clear in the Scriptural text and in the context of tongues they spoke and they heard. and the Gifted used was that of tongues unknown. I do not need to explain how God did it I just believe God did it, as the bible states.
Huh. I hadn't noted what you say here about them being mocked. Every time I've read it I couldn't get past the wonder of each hearing in their own language! But some mocked. Some DIDN'T hear it in their own language. Their hearts were shut.
