As there are some , such as Dr Grudem/DA Carson, who would argue for at least prophecy still remaining for church today?

The problem with "prophesy", in particular, it presents an insurmountable problem in regard to verbal plenary inspiration. IF someone claims, "God told me that such and such is going to happen, etc." and it doesn't come to pass exactly as allegedly told, then Deut 18:20-22 is applicable. The claim to prophesy in the name of God after the Canon was closed is to deny a closed Canon and assert that God continues to communicate to private individuals with divine truth. And divine truth MUST be infallible and it must also be obeyed. ALL that God has desired to communicate to man and what is required of man in this life is contained FULLY in Scripture and Scripture alone.

I fully agree with you, and also think those 2 brothers know that we would claim they are violating the scriptures with extra biblical revealtion, so forced to see it not as sense of a prophet, more like in the sense of gining insight/widom from God, so watered down the term!

Thoughts? I would argue they are very inconsistent. It is an incorrect position. It is surprising to me that any could have said position....
HOWEVER....many of us, myself included, have positions OTHERS would consider inconsistent. This i NOT a post to say 'anything goes'...far from it! But when we notice what we deem an inconsistency...we should explore it further, to ensure it IS so.

If you study Acts you will find that only the Apostles had the Baptism of the Holy Spirit, which included the Charismatic gifts. Called the signs of an Apostle. They alone spoke in tongues along with those they laid their hands on. Peter was present at the gentile outpouring linking him to that event.

The first clue that today's gifts are fraudulent comes from Paul when he says understanding what is said edifies. He then says those who speak in tongues edify themselves. This can only mean they understood what they were saying. None of today's "tongue speakers" know what they are saying.
