I don't believe the true test of a prophet applies to this one. I believe these are false teachers, who are incorrectly intrepreting the written word; they're not false prophets.
It seems like a small difference, but I like to be precise when drawing conclusions from the bible. It helps to avoid nonsense like this nuke hitting the eighteenth floor, second window from the right, at ten fifteen AM, when the moon is in the second house, and jupitor aligns with Mars, and ........
"predictions" was the word first used in the article which is what led me to my statement, since predictions and prophesy are somewhat similiar. But you may be correct since the article does not say they are using "new revelation" for their prediction. Since they are using the words of God already prophesied to make their "prediction", false teacher is the better term.
