I came across this older WT which I assume C T Russell wrote the article. Unlike modern practitioners of numerology who calculate a value for each letter of the alphabet, Russell simply adds up the number of letters in each word to arrive at [horror of horrors] 666.
And he lists there on the page each one of the organisations that must accordingly be part of the Great Harlot with 18 letters [in English] in their titles, because 18 is clearly 6+6+6 or 666!
Strangely he hasn't stopped to think about another possibility for an 18 letter title. It is "Charles Taze Russell" adding up to 18 letters or 666.
It'd make you laugh, except for the fact that people took everything Russell said as if it was coming from the mouth of Jehovah. A flawed way of thinking that permeates right down to this day.
