People are far too loose with the labels of prophecy and prophet. In Torah, a prophet is held to a higher standard than anyone but the High Priest.

According to Deuteronomy 13:1-5, any prophet who leads the people to serve any god except YHWH--even a god masquerading under the name of a righteous saint, such as Mary or Peter--is to be tried and executed by the civil court and the people, even if his prophecies are true.

According to Deuteronomy 18:20, if anyone claims to be a prophet and his prophetic predictions are proven false, we are to ignore everything else he says.
