the WT / JW position on this has been consistent since Russell.
Wait wait wait. I don't care WHAT the WT position is as to what a prophet is. I'm concerned about what the Bible's position is on what is a true prophet!
According to Deut 18:20-22 a prophet speaks in God's name. A false prophet speaks in Gods name (or authority) and says that something will happen and it doesn't happen. The bible says, THIS MAN SHOULD DIE!
So there is no cherry picking here. The Bible doesn't say that if the prophecy doesn't come true and you apologize for it then you are NOT a false prophet. It does not say that if you are moral and teach OTHER things that are correct that you are not a false prophet.
The FRUIT of a prophet is: True Prophecy. The FRUIT of a false prophet is: False Prophecy. The one that produces bad fruit, or false prophecy, is cut off and thrown into the fire. That is the result that these false prophets have waiting for them, per Jesus Christ.
