Doesn't the bible mention something about false prophets needing to be put to death? And a prophet is not just some dude with a walking stick, long flowing white hair and beard, and a name like Ezekiah. It's anyone who engages in prophesies.
As has been posted above somewhere . . . there are several examples in the Old Testament where highest quality prophets missed it in a sense and were not stoned to death.
Then there's the whole issue of Holy Spirit operating today is different from OT when He was only resident in a few.
And, AS I Cor 14 illustrates, THE LOCAL BODY OF CHRIST--THE LOCAL CONGREGATION IS TO DISCERN WHETHER A GIVEN PROPHECY IS ACCURATE, FITTING OR NOT. AND THERE IS NO HINT IN THOSE MANUAL VERSES OF AN EXHORTATION TO STONE THE PROPHET WHEN A GIVEN PROPHECY IS NOT UP TO SNUFF.
Consider the WHOLE COUNSEL OF GOD IN THE WHOLE OF SCRIPTURE when deciding an issue.
BTW, I'm not very willing to argue about this.
