As I mentioned a few times in this thread, this is why
1stCenturyLady and a small number of Pentecostals feel that they have a need to say that the Holy Spirit fell upon both the 120 and the unregenerate crowd in that unlike the Epistles and with the other examples in Acts, the situation in Acts 2 on the surface goes against the grain in that on this single occasion tongues were given in known human languages.
So, even though on the Day of Pentecost the Holy Spirit spoke through the 120 in known human languages and that this differs from what Paul has told us in 1 Cor 14:2;
(14:2) For anyone who speaks in a tongue does not speak to people but to God. Indeed, no one understands them; they utter mysteries by the Spirit.
Those who feel that they have a need to try and reconcile the known human languages of Acts with Paul’s teachings in
1 Corinthians 13 & 14 that tongues are always spoken to God within inarticulate tongues, they need to keep in mind a number of things:
1. The Day of Pentecost was a unique and unrepeatable event in that this was this giving of the Holy Spirit to the Children of God.
2. The content of what the 120 were saying to the Father matches that of 1 Cor 14 in that they are also words of praise being directed to the Father and not some supposed Gospel message to the unregenerate. As with the Epistles, the tongues that Paul speaks of and the occurrence on the Day of Pentecost, both are being directed to the Father and as Paul has told us, tongues are ALWAYS directed to the Father and NEVER to man, so Acts 2 is in line with 1Cor 14.
3. On the Day of Pentecost tongues were also accompanied by the sound of a rushing wind and tongues of fire resting upon the Believers, this has never occurred since this time.
4. The crowd were so confused by what they were hearing that this matches what Paul said in 1Cor 14:23 that when the unregenerate encounter everyone speaking in tongues that “they will say that you are mad”. If Peter had not provided an evangelistic message then the crowd would have moved on thinking that the Galileans were in fact drunk.
5. Whereas Paul forbids the corporate use of tongues where everyone within a congregation sings or speaks words of praise to the Father during times of praise and worship, we find all of the 120 speaking words of praise to the Father on the Day of Pentecost.
6. Paul also demands that every occurrence of tongues first be interpreted before another is given and of course this did not happen on the Day of Pentecost.
7. Unlike congregational tongues which must only be undertaken when they know that someone is present who the Holy Spirit provides an interpretation, this did not occur on the Day of Pentecost.
