There is nothing in the text of Acts 2 to suggest the 120 were conducting the first prayer and praise service of the church. They were given those tongues for a reason and Peter makes it clear in verse 21.
We do have Acts chapter 3 to show us a distinction between what is clearly 'praise for God' and what is preaching the Gospel:
There has certainly been a huge amount of older commentary that has suggested that the words that the Holy Spirit spoke through the 120 were supposed to be an evangelistic message to the unregenerate Jews but there is nothing in the context that suggests that this was the case. What we do see from the text is that they were (v.11) “declaring the wonders of God in our own tongues” which is exactly the same as what occurs during times of praise and worship within the context of the congregational setting. As with 1Cor 14:2 the tongues of Acts 2 were being directed toward the Father which is who the Holy Spirit will always speak to when he prays through us.
About all the crowd could figure out was that these Galileans were speaking in languages that they would not be expected to know about the wonders of God. If some in the crowd had not approached the Twelve, which enabled Peter to preach the Gospel, the crowd would have left the precinct not knowing what was going on.
What I am trying to point out in my posts, is that the tongues in Acts 2 are most likely not the tongues Paul speaks of in
1 Corinthians 12-14. It is clear in Acts 2 foreigners (or diaspora Jews who were born in raised in foreign countries) heard their specific language that day. And that tells me what happened on Pentecost was different from what Paul speaks of when he says: "For he who speaks in a tongue does not speak to men but to God, for no one understands
him..." (
1 Corinthians 14:2). It is obvious on Pentecost the tongues heard were understood by those of various languages. Therefore, there is a difference here.
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.
To answer the OP in that one must speak in tongues to be saved; or do the saved all speak in tongues (the tongue which speaks to God and not men---no one understands him), the answer is
1 Corinthians 12:
Even though Paul indicates that it was normative for the Christians of his day to speak in tongues, he never indicates that someone must demonstrate their ability to speak in tongues before we can deem them to be Saved.
As a Pentecostal who understands this, I still acknowledge that this normative experience is for the entire Church age, where prior to a Salvation call, any Pentecostal meeting that does not encourage potential initiates to speak in tongues essentially disenfranchises or cheats the prospective new Believer out of a full Spirit empowered Salvation experience; but, if someone confesses their sin and acknowledges Jesus as their Lord and Saviour then they are indeed Saved, but sadly, they have missed out on a full Biblical Salvific experience – but as I said, they are still Born Again of the Spirit of God.
