The gift of interpretation is not mentioned in that passage. It is hard to figure out exactly what you are reading into that passage. I understand every word in that sentence, but I don't get your point.
Peter did not speak in tongues . Tongues are sign for those who believe not.
I don't see anyone in this thread glorifying Peter or claiming that the ability to speak in tongues or for other people to hear him came from Peter.
1Co 14:22 Wherefore "tongues are for a sign", not to them that believe, but to them that believe not: but prophesying serveth not for them that believe not, but for them which believe.
What would be blaspheming? And how is whatever you are talking about relevant to the discussion?
Men neither get the credit for speaking prophecy in their own language and the same to those in whom the Holy Spirit did the interpreting.
All of the gifts work in each person to the one who speaks the word of God to the one that hears it in their own language.
Divers tongues is also given to individuals in the body of Christ for the common good. The individual who speaks in tongues edifies himself. We know this is a good thing because of Paul's comment, 'I would that ye all spake with tongues'. It is better to interpret in addition to speaking in tongues or else prophesy, which we could see in Paul's other comment 'but rather that ye prophesied.'
You say that over and over again.
I don't know what you mean by that. I suspect no one else on the forum does but yourself. The term 'sign gift' is typically used by cessationists who want a category to put all the gifts they aren't comfortable with in so they can get rid of the whole category in their theology, at least as far as practical application in the church today is concerned.
I would think living in a society that is taught the idea of “sign gifts” is where what I would call in this case the confusion begins. No such things as a sign gift to prove a person has the Holy Spirit.
The apostate Jews sought after a sign of themselves doing (experiencing) some religious work as evidence Christ is with them. (self righteousness) The cross was their stumbling block that remains today.
It is why Christ said to them below.
And ye have not “his word” abiding in you: for whom he hath sent, him ye believe not.”Search the scriptures”; for in them ye think ye have eternal life: and they are they which testify of me.And ye will not come to me, that ye might have life.I receive “not honour” from men.. Joh 5:38
Therefore making the word of Christ, the faith of God without effect.
We walk by the faith of Christ, not after some work we can do and call that a gift. Signs are for those who believe not.
That law is not subject to change by an outward work we could perform..
