The canon of scripture is closed just as special revelation is closed.

Those who “receive a special revelation from God” had better be “receiving” something already revealed in the Bible, or they are false prophets, saying something God has not said. Revelation 1:18 is self-referential and states that thie Revelation of Jesus Christ covers “what shall be hereafter.” When combined with Revelation 22:18,19 it paints a dire fate for these false prophets. 22:18 and :19 lay a curse on anyone who would add to or take away from this revelation. That curse is damnation, having one’s part removed from the Book of life.
I wasn’t referring to private revelation.
