"And I saw a woman sitting on a scarlet beast which was full of names of blasphemy, having seven heads and ten horns. The woman was arrayed in purple and scarlet, and adorned with gold and precious stones and pearls, having in her hand a golden cup full of adominations and the filthiness of her fornication. And on her forehead a name was written:
MYSTERY, BABYLON THE GREAT, THE
MOTHER OF HARLOTS AND OF THE
ABOMINATIONS OF THE EARTH.
I saw the woman, drunk with the blood of the saints and with the blood of the martyrs of Jesus. And when I saw her, I marveled with great amazement."
Revelation 17:3-6 (NKJV)
In the world of sola scriptura, don't they read the part that says false prophesy regarding such scripture is extremely sinful?
