Have declared no such thing.
And you know it.
You are the ones insisting on an Old Testament response to a New Testament reality.
Have you decided the NT is of little or no value to the Christian life?
Tell us, Quix, what is the appropriate "New Testament Response"? More specifically, what is the New Testament test to determine false prophecy? Tests of accuracy, i.e. "didn't come to pass as prophesied", are part of the "Old Testament Reality" that you repeatedly claim has little application to our NT-era lives.
While you're at it, show me the NT injunction against beastiality. There was one in the OT, but none in the NT. Using your "OT vs NT" Rules of Reality, sleeping with farm animals is no longer a sinful offense.
Do you have a friend who considers himself, or perhaps you consider yourself, to be an anointed Prophet of the Lord?
