Dr. Ernest Martin and Fred Coulter are part of the Armstrong's Worldwide Church of God
and its splinter groups. These groups do not believe in the deity of the Holy Spirit
and have other false doctrines. Even worse, the group's behaviors (mind control, etc)
are not acceptable before the Lord.
You can learn more about Armstrong's Church of God and its splinter groups at
as well as in Amazon. The reviews (Scott L. Adams, Richard Hopkins, TJ, G. Miller, etc) for 1st edition leather-bounded
OOB had been deleted. They were placed back in the (1st edition) paperback OOB. If they get moved again, look at the
reviews for other editions (leather-bounded and paperback).
If you wish to read more commentaries about the bible being 49, instead of 66 books, books, then read free online book
of "Restoring the Original Bible" by Dr. Ernest Martin and the commentary of the expensive OOB. Be careful of
false theologies. I did not perceive the deception for several months.
