Then we're agreed on that.
Oscarr, just be on guard. This can be a liability rather than a strength. Some of your posts are very revealing about how you arrive at your positions. As I stated, you appear to have gone overboard on conservative theology at some point, and this may have been where. I own a library full of scholarship, and they are not always right.
And how do you prove this exegetically? The text states that those who were speaking in tongues were Galileans. (Acts 2:1-7).
1 When the Day of Pentecost had fully come, they were all with one accord in one place. 2 And suddenly there came a sound from heaven, as of a rushing mighty wind, and it filled the whole house where they were sitting. 3 Then there appeared to them divided tongues, as of fire, and one sat upon each of them. 4 And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit gave them utterance. 5 And there were dwelling in Jerusalem Jews, devout men, from every nation under heaven. 6 And when this sound occurred, the multitude came together, and were confused, because everyone heard them speak in his own language. 7 Then they were all amazed and marveled, saying to one another, “Look, are not all these who speak Galileans?
Statements like these truly baffle me. Signs and wonders are not spiritual gifts? How is healing not a spiritual gift? (1 Corinthians 12:9)
Are you interpreting a "spiritual gift" to be an individual act rather than a spiritual endowment? If so, that would be taking the term out of context IMO.
