I appologize for the length due to my answers
I have AoG background as well, and 18 months Berean Bible college courses in the 80s.
However ths scriptures do not ever say "THE evidence of speaking in tongues" It can be one evidence, but any gift of the Spirit can be."
Paul also makes it clear not all speak in tongues.
Surely you must know that before any believer can operate in any of the other gifts of the Spirit, they must have the evidence of speaking in tongues.
And, surely you understand from your AoG background that the apostle Paul was in that above text referring to the ministry gifts of publically speaking forth tongues that is a separate operation from every Christian believer to whom God has given without partiality, to speak in tongues.
The very example of all speaking in tongues is in evidence within the believers at Corinth.. clearly they all practiced it, yet he told them without apology, and without pride, Thank God that I speak in tongues more than you all.
Consider Acts 4:31 as well:
"And when they had prayed, the place was shaken where they were assembled together; and they were all filled with the Holy Ghost, and they spake the word of God with boldness."
The context indicates that it is useful for any believer who might be timid about sharing their faith with anyone, especially in the face of perceived or real opposition.
Acts 19:6 states they both spake with tongues AND prophesied.
"And when Paul had laid his hands upon them, the Holy Ghost came on them; and they spake with tongues, and prophesied."
Are you giving this as an example of what you think should accompany every incidence of speaking in tongues? That would have to be an assumption on your part.
Have you not consulted every verse that speaks on the topic? On the day of Pentecost in Acts 2:4, there is no indication that they all prophesied after they'd been filled with the Holy Spirit.
There are any number of other incidences that don't include prophesying when there is the report of speaking in tongues.
1 Corinthians 14:1
Follow after charity, and desire spiritual gifts, but rather that ye may prophesy.
This verse indicates that prophesying does not automatically follow speaking in tongues, as I think that you are attempting to imply. But the apostle Paul encourages believers in prophesying as a goal to attain to by faith as they continue to practice the speaking in tongues.
Who is going to require the pace of that attaining such a goal? The apostle Paul didn't give any.
Then the entire chapter goes on about tongues and prophecy..with instructions on how to properly exercise the gift of tongues, which I have seen many Christians and entire churches go way of track...especially this:
verses 27 - 28
"If any man speak in an unknown tongue, let it be by two, or at the most by three, and that by course; and let one interpret.
But if there be no interpreter, let him keep silence in the church; and let him speak to himself, and to God."
This assumes that the church is practiced enough concerning the teachings that the congregation is aware that there would be no one there who has the ministry of interpretation operating among them.
Who is to put an achievement pace on any church assembly? The believer in the pew looking with disapproval on all other believers? .. the pastor?..
Your AoG background should tell you, why Paul gives only encouragement, not disapproval, not rebuking, for those who speak in tongues to seek to be able to interpret and therefore prophesy to edify the entire congregation.
The verse about being silent and speaking to himself and to God is speaking to those who do speak with tongues, therefore following the verse, "he that speaks in tongues edifies himself."
Yet I have seen people blurt out tongues with no interpretation, or a bunch of people start speaking tongues with no interpretation, not just 2 or 3.
Since you come from an AoG background, You should recall the pastoral leadership that gives permission for such things to be allowed.
And, you should recall that it is during congregational prayer, worship and praise unto God.. which is personal and therefore does not need to be interpreted for the entire congregation to know what private matters are being communicated.
Another place where "he that speaks in tongues edifies himself" comes into practice.
Your AoG background should remind you that the stipulation of 2 or 3 to interpret at the most is to limit the offerings of what would otherwise be the unorderly multiple interpretations that would ensue.. or simply the zealous believer speaking in tongues too loudly and be mistaken for a ministry tongue.
This teaching of Paul's is according to those in the church assembly who are operating in the ministry gift of tongues.. they should either have unction of the Holy Spirit to interpret it themselves, or wait for the ministry of interpretation. If no one knows that they have such a ministry, then the church has what you describe.
Which is where the encouragement of Paul to follow after being perfected in God's love, if the Holy Spirit should grant, to operate in the ministry of interpretation.
But, with that first is experienced awkward occasions until the teachings and the faith and spiritual knowhow and growth finally produces the well sounded symphony of the operational gifts of the Spirit.
All of this is what I've learned from having an AoG background.
