It reminds me of the controversy in Thomas More's time about the Holy Maid of Kent. It seems she confessed to being a fraud (although how would we know? All the info about her confession is from Thomas Cromwell and Henry VIII's henchmen). She did speak the truth that Henry's divorce of Queen Catherine and marriage to Anne Boleyn was a sin. Some of her prophecies turned out true; some not.
My point (as I’m sure you understood) was that good results happen through God’s grace in situations that may not be (or clearly are not) holy in origin.
