What the Sunday Watchtard said...
In 1876, an article written by Charles Taze Russell was published in the magazine Bible Examiner. That article, “Gentile Times: When Do They End?,” pointed to 1914 as a significant year. The article linked the “seven times” of Daniel’s prophecy with “the appointed times of the nations” spoken of by Jesus.
What Gentile Times: When Do They End? (1876) said....
At the commencement of our Christian era, 606 years of this time had passed, (70 years captivity, and 536 from Cyrus to Christ) which deducted from 2520, would show that the seven times will end in A.D. 1914: when Jerusalem shall be delivered forever, and the Jew say of the Deliverer, “Lo, this is our God, we have waited for Him and He will save us.” When Gentile Governments shall have been dashed to pieces; when God shall have poured out of his fury upon the nation, and they acknowledge him King of Kings and Lord of Lords.
So... it sounds like he didn't say it was "significant", it sounds like he said it was going to be Armageddon to me... But what do i know
