before the 1975 failure, here's what WT promoted:
1974 "Yes, the end of this system is so very near! Is that not reason to increase our activity?...Reports are heard of brothers selling their homes and property and planning to finish out the rest of their days in this old system in the pioneer service. Certainly this is a fine way to spend the short time remaining before the wicked world's end." (Kingdom Ministry, May 1974, p. 3)
After 1975 failed, suddenly WT didn't really say what they said in 1974:
1976: "It may be that some who have been serving God have planned their lives according to a mistaken view of just what was to happen on a certain date or in a certain year. They may have, for this reason, put off or neglected things that they otherwise would have cared for. But they have missed the point of the Bibles warnings concerning the end of this system of things, thinking that Bible chronology reveals the specific date." (Watchtower, July 15, 1976, p. 440)
1979: Partly because of eagerness to be alive when Jesus Christ reveals himself in glory, there have been believers throughout the centuries who began looking for a particular period or a year for the windup of the ungodly system of things. this has happened right down to these "last days." Since certain expectations were not realized, many stumbled and returned to the ways of the world. In fulfillment of Peter's words, even today we hear the voice of ridiculers. (2 Peter 3:3,4) (Choosing The Best Way Of Life; 1979; p. 169)
"But some of their time calculations and the expectations that they associated with these gave rise to serious disappointments. Following 1925, meeting attendance dropped dramatically…. Again, in 1975, there was disappointment when expectations regarding the start of the Millennium failed to materialize. As a result, some withdrew from the organization…. Although these tests resulted in a sifting… others remained firm. Why?… ‘Those who had set their confidence in Jehovah remained steadfast and continued their preaching activity.’"—Jehovah’s Witnesses — Proclaimers of God’s Kingdom, Watchtower Bible & Tract Society, 1993, p. 633
Isn't "sifting" great?
WT demands that JWs believe false prophecies and build their lives around specific dates. Then when WT's prophecies fail, its attitude toward those who recognize false prophecies and leave WT, is, 'good riddance!' We have no tolerance for people who get disappointed when "god's sole channel of communication' promotes false prophecies.
In other words, shame on you (rank and file JWs) for actually believing us (WT)!
Oh, by the way, here's our latest prediction you have to believe....
