I was in my teenage years during the 1975 fiasco. I was not much of a '75 person, more of a 1914+generation believer but I still took it somewhat seriously.
Two things about '75 stood out.
First was the mid-week meeting. They were reading from the kingdom ministry paper. It was the part where they said that there where "reports of brothers selling their homes and spending the remaining time available pioneering".
Then there was Freddie the chronological voodoo priest. I went to a meeting at the forum stadium in Inglewood, California (where they played basketball) where Freddie gave a talk on 1975. There was a packed audience with seats at the floor of the court (10,000?).
It was a long talk where he started with the creation of the universe, went through human history - a la Bible - and climaxed at 1975 which he explained in detail. And there was a detail about '75 that I never hear mentioned amongst the 'Apostate' community. It was the "Adam and Eve gap".
The Adam and Eve gap was the time period between the creation of Adam and the creation of Eve. It was only when Adam were both together that the 6,000 year period began and it would affect the beginning of the Millennium - the last 1,000 year of God's final 'creative day of 7,000. That Adam and Eve gap could have been months or years (actually up to 130 years before Seth's birth minus the amount of time it took for Cain and Abel to grow until one killed the other).
Freddie explained in meticulous detail how the Adam and Eve gap could affect the 'Great Tribulation. Based on his explanation the tribulation could actually start within several months to several years after October of 1975. On a bizarre note, even though that gap could have lasted for decades Freddie said that it would not. The reason? If Adam had no Eve for several decades he would have been tempted into bestiality. Yes, that was his phrasing. I actually recorded that but I don't know what happened to the recording cassette.
This was the type of reasoning that kept me from wearing orthopedic braces to correct my scoliosis. To this day I walk with a crooked back.
