defender of truth I was using my phone last night and now I am able to use the computer. These are a few quotes from the publication that the slave felt we needed to study in 1974.
God's Eternal Purpose Now Triumphing for Man's Good (1974 WTB&TS) In the front of this book my wife has written the date August 1974 and the assembly she recieved the book. Inside there are several other dates relating to when it was studied at the meeting, starting in December 1974 and the last date is May 1975. Which to me means that at that time it was the most up to date fresh spiritual food given by the faithful slave.
On page 131 in paragraph 5 it states,
"The first half or 'evening' period of God's seventh creative 'day' was now closing, 3,500 years from the creation of Adam and Eve. The morning of this creative 'day' was due to begin at 526 B.C.E ."
This was under the heading, "Morning of the seventh Creative day begins 526 B.C.E."
Earlier in the book on Page 51 there is a subheading "Evening of the Seventh Creative Day begins 4026 B.C.E."
From these statements I would conclude that the seventh creative day was 7000 years in length and started in 4026 BCE. Maybe I reading it wrong but I don't think so as this is what I understood at the time that we believed the creative days to be 7000 years long.
On Page 53 the book says "At the beginning of this 'seventh day' almost six thousand years ago God 'proceeded to bless the seventh day and make it sacred.'"
As it says it was almost 6000 years into the seventh creative day. Which I believe would be exactly 6000 years in in October of 1975 from the start date of 4026 BCE
The last chapter of the book is "Making the Seventh Creative 'Day' Sacred" page 187.
on page 189 talking about Satan the Devil it reads,
"For six thousand years he and his seed have been allowed to continue their effort to make it seem to be a cursed day unsacred... During the thousand years that the Great Serpent and his demon seed are abyssed, Jehovah will reverse all the wickedness."
This thousand years of the Devil being abyssed was yet to come but before the end of the 7000 year seventh creative day.
On the following Page 190 it says,
"...God's seventh creative day will end up blessed, sacred, sanctified. Jehovah having blessed that day six thousand years ago..."
On page 186 it says "With all his earthly seed destroyed at Har-Magedon," it then asks the question "Are the original serpent and his invisible demonic seed to be left on the loose in the vicinity of our earth down to which they have been ousted from heaven? No!"
"By removing the Serpent and his demons from the nieghborhood of the earth and hurling them into the abyss and sealing them up there, bound as with chains for the next thousand years. Revelation 20:1-3 pictures this, not as a part of the war at Har-magedon, but as a follow up of that war."
I would conclude from this that Har-magedon is before the last 1000 years of the 7th creative day which started in 4026BCE and 6000 years is up in October 1975 and we have been provided with this material in 1974 and studied it after. I think this was the most up to date material at the time maybe i'm missing something in reading it or understanding it.
On the internet site that you mention i believe that it says one of the reasons that people focus on 1975 is to show that the Watchtower are false prophets. The reason I focus on it at times is because it altered my life and even up to recently i've had elders who say it was brothers speculating on what the faithful and discreet slave class were providing as spiritual food, I don't feel that is true.
