"The whole purpose of that booklet is to convince the readers..."  
How does this one isolated sentence convince the readers? 
========== 
There's an easy-to-understand difference between 
"The purpose of this book is"  
and  
"Every sentence in this book specifically pushes the purpose of this book, which is" 
This means that one can find individual sentences that don't push the purpose 
of a book written with a purpose.  
(If the entire Bible can be considered to have the purpose of the plan of salvation, 
whole chapters can be found that don't point to it.)  
CSBP, as a whole, WAS a booklet-long commercial designed to convince people that 
A) they needed to give 10% of their income, according to God 
(this has been proven false) 
B) twi, as the best vehicle for giving to God, was the proper recipient of the 
10% to give to God  
More of twi's other stuff was pointed at "the giving goes to twi" than the booklet. 
The booklet was primarily to convince people the giving was mandatory.  
Lots of other things here and there were pointed at giving to twi specifically- 
like vpw saying in twi that, instead of giving to other causes, why not give 
to Bible research-and pausing with a small smile to make sure that set in,  
and was viewed at the moment as a joke rather than part of the advertising  
campaign in twigs and all other types of twi meetings.  
But in twi, the special treatment for the wealthy and famous has been  
well-documented. They were honored in manners unofficial and official.  
They were introduced onstage at the ROA, and they were given WOW pins they 
never earned, and so on. Even lcm objected to vpw bringing a judge onstage 
at an ROA who was considered prideful- but he was influential. And some 
rank-and-file resented Tony Collins of the New England Patriots getting 
awarded a WOW pin by vpw personally despite never entering the WOW program. 
vpw invented some spin about him actually being a WOW while at work 
despite never actually fulfilling any requirements of the program. 
Even the innies at the time who heard of it objected, because it was a 
blatant example of "respect of persons."
