A stunning egotist and vain person, Herbert Armstrong, whose biographer Herman Hoeh, claimed Armstrong to be "of royal blood", claimed that this book was "The Greatest Book Since the Bible". Upon reading it, however, it is more than filled with heresy, trite aphorisms stolen from other cultic religions, endless plagiarism and the shallowest hermeneutics a first year baptist Bible College student could take apart in 10 minutes.
The book was wholly written to serve Armstrong's enormous ego and unify, doctrinally, his paper maché cult, The Worldwide Church of God; which promptly dissolved upon his death in January of 1986 into many unprosperous and ineffective splinter cultettes to say nothing of the large production of a new pile of atheists. Of whom, I am one.
(Addendum) Not to mislead. The above two previous sentences do imply I left the faith to Armstrong. No. Not as Hebrews says, no "root of bitterness" was endemic in me. More like what Buddha said, "I'm awake." Like a sinless Pilate, washed my hands of the whole scheme and happily walked away.
