The original aim of CT Russell in starting the Watchtower magazine in 1879 was to announce to the world his pet idea that Jesus had come to rule in the heavens five years earlier back in 1874. For the young entrepreneur this new magazine looked like a commercial runner and it was!
Most of us know how profoundly false the prophecy was but if you don't mind I'll give a brief overview for newbies:
1874 was the failed Adventist prediction year for the return of Christ in the heavenly glory, which Russell was now saying was the right year after all. He said that Jesus did arrive that year, not visibly but instead invisibly as king of the kingdom. One significant evidence which Adventists had been relying on was the scripture in Daniel based on 607 BCE as the date when Jerusalem was destroyed by Cyrus. Russell said that this date 607 BCE was the pivotal date for predicting the end of god’s enemies on Earth. Working out and projecting forward “seven times” by Biblical fancy footwork and corroboration by pyramid measurements, he taught the very latest time by which the planet would be rid of Satan's influence was to be by 1914. Given a Biblical forty years from 1874 to make 1914 the time it would take this new heavenly kingdom to destroy God's enemies and restore the world to paradise purity.
The Watchtower magazine got every detail wrong. . . as wrong as wrong can be. Remember too that this prophecy was the very reason for its existence!
I hardly need remind you that 1914 was anything but paradise. How can invisible heavenly events ever be proved anyway? No academic historian concludes 607 BCE to be the year of Jerusalem’s final destruction by Cyrus, this being critical in pinpointing 1914, Daniel (who could not have written Daniel) wrote his prophecies in around 165 BCE, centuries after the events foretold! Nice move ‘Daniel’ whoever you were! And what have pyramids got to do with anything here?
Since ABSOLUTELY EVERYTHING about Russell’s predictions were wrong; therefore the foundations of JW beliefs were also wrong: - what legitimacy for their very existence do the inheritors of the Watchtower have?
