In summary:
Now Jehovahs Witnesses believe in the Rapture. . . . but they don't call it the Rapture
And they believe in tithing. . . . . but they don't call it tithing.
As a side note, I told my wife about this letter and she is very impressed with my predictive "powers." Over a year ago I told her I thought they might implement some sort of tithing arrangement, and she thought that was impossible. Looking at it from a business perspective though (which no JW does) it only makes sense as your base shrinks in developed nations and is expanding in poor uneducated countries.
