I never believed that one false prophecy made a false prophet. I think the false prophets were the prophets of Baal and such. Kim Clement made a couple mistakes. Does that make him a false prophet? He claimed he might be a wrong prophet but not a false prophet. If we kill everyone that made a mistake the whole population would disappear.
If the person is claiming to be passing on some word from God, IOW a prophecy, then he'd better be right 100% of the time. Otherwise, nobody can trust any future pronouncements.

According to Scripture it does.
Deuteronomy 13 and 18 address this.
If the person who calls themselves a prophet is wrong even once, then how can you know you can trust them the next time they claim to speak out a prophecy?
Taking every *Thus saith the Lord* pronouncement as from God, is a sure fire way to fall into deception.
It's not grieving the Holy Spirit to use discernment to test the spirits as God commanded us to do.
