Terry: JW's were defeated, dispirited, and depressed and they just gave up.
Those people have swallowed the whole thing and shit it out and flushed it away like it never happened.
There. That's your answer.
Cognitive dissonance.
Pre-1975, the brains of Brooklyn were still laboring under the notion that there were 7 creative days of 7,000 years each. They believed that Eve's creation marked the end of the 6th creative day and that the next 7,000 year period was god's rest day.
They concluded that Adam had been created in 4026 BCE and that Eve was created shortly afterward. If you add 6,000 years to the year date of 4026 (no zero year), the result is 1975 CE. By 1975, 6/7ths of god's rest day would have been expended. It made such a neat package to say that the last 1,000 years of god's rest day would be the 1,000 year reign of Christ. So, 1975 must be the beginning of the 1,000 year reign, ergo armageddon is coming or will be over by 1975.
After the big letdown that Terry described, the spin doctors had to come up with something to rally the troops. So they claimed that they missed the mark on 1975 because there is no way to tell how long the period was between the date when Adam was created in 4026 and when Eve was created. Now, they conveniently decided that it could have been a few months or it could have been a few years, which pushed out the 6,000 year anniversary of the end of creation a bit. That bought them enough time so that some of the faithful let the whole thing drop, and no longer "served Jehovah for a date". Yes, according to the Society, this whole thing was our fault. We were the ones who pushed ahead and made 1975 into such a big deal.
Some JWs couldn't dismiss that whole mess quite as easily, some dropped out, some couldn't cope. I am very sorry to hear of what happened to your wife, Terry. What a tragedy.
