The following comes from William Rowlands, Twyll Mormoniaeth: yn nghyd a hanes bywyd a marwolaeth Joseph Smith, o America, Prophwyd Santyddol y Dyddiau Diweddaf (English: Deceit of Mormonism: Together with the History of the Life and Death of Joseph Smith, from America, the Hallowed Prophet of the Latter Daysi) (Merthyr Tydfil: David Jones, 1852), we read the following appeal to Rev 22:18-19 on pp. 13-14 (proving the more things change, the more they remain the same):
Q. Is it not
possible, as in times of old, to chronicle and set forth the revelations of the
Bible?
A. No, it
is not possible.
Q. Why not?
A. Because the
Book of Revelation of Jesus Christ to John in his prophecies extends to the end
of time; and there is a commandment not to add to it, or to take anything away from
it.
Q. Yes, to
the prophecy of that Book, but would it perhaps be permissible to add to the
Bible, despite that?
A. No, it would
absolutely not be permissible, since the Book of Revelation, is the last book
of the Bible, and it was written, Woe unto anyone who adds to it.
Q. What does
the Revelation of Jesus Christ to John say about this?
A. “If any
man shall add unto these things, (namely the words of this prophecy) God shall
add unto the plagues that are written in this book,” Rev. 22, 18, 19. It might
be thought that it might be sufficient to any man who treasures the salvation of
his soul more than the hypocritical whim and sinful pride of his corrupt heart.
