The DIDACHE is at above URL.
CHAPTER 11
11:1 Whosoever, therefore, shall come and teach you all these things aforesaid, him do ye receive;
11:2 but if the teacher himself turn and teach another doctrine with a view to subvert you, hearken not to him; but if he come to add to your righteousness, and the knowledge of the Lord, receive him as the Lord.
11:3 But concerning the apostles and prophets, thus do ye according to the doctrine of the Gospel.
11:4 Let every apostle who cometh unto you be received as the Lord.
11:5 He will remain one day, and if it be necessary, a second; but if he remain three days, he is a false prophet.
11:6 And let the apostle when departing take nothing but bread until he arrive at his resting-place; but if he ask for money, he is a false prophet.
The Didache is clear about false prophets as is Scripture, but these days, in charismatic circles, a so-called "prophet" who predicts the future saying it is a prophecy from God is not required to meet the test of Scripture of 100% accuracy 100% of the time, they just have to have a good rap.
As opposed to Scripture's exhortation to "test the spirits", I believe that "Quix" would have us take these so-called "prophets" carte blanche as being the real article, no matter how many times their "prophecies" are wrong. That's a shame.
