Heads up on the 1914 date for Jesus return...
this is the core creed of the Jehovah's Witnesses
In the early 1820's, a strange fellow by the name of John Aquila Brown took a few Bible texts completely out of context and came up with an absurd speculative calculation (360 X 7 = 2,520) in a half-assed attempt to determine the length of the Gentile Times.
A few decades later, leaders of several "dooms-day" religions, including the Adventists read "The Even Tide" (1823) by John Aquila Brown and saw an opportunity to cash in on some well-organized fear-mongering campaigns. This was the beginning of the Armageddon craze.
Charles Taze Russell liked what he saw and wanted a piece of this action. So he jumped on the band wagon but decided to create his own unique product so he searched for Bible texts to take out of context and created an incredibly embarrassing list of new doctrines which has taken the Watchtower over 100 years to clean up albeit they're still stuck with quite a few.
Some of these religions even pointed to particular years such as 1913, 1915, 1917, etc.
Charles Taze Russell decided to go with October 1914.
Obviously, Armageddon didn't arrive in 1913, 1915, 1917 or even the Bible Student's date of October 1914. So all of these religions decided to abandon this completely unauthorized calculation (Acts 1:7). But Russell saw an opportunity to clean up his mess by simply latching on to World War I (which really started in July 1914... not October 1914) and then simply used a phrase that is still in use by the Watchtower Corporation today... "Current Understanding".
The phrase "current understanding" along with Proverb 4:18 soon became the Jehovah Witnesses free pass to change their flawed doctrines and failed predictions at will.
While all of this was ongoing, the Bible Students certainly DID NOT expect Jesus to return in 1914 (as the WT would have the rank & file believe today) as they were taught in no ambiguous terms that he had already returned in 1874 and it wasn't until the late 1920's that Rutherford decided to move 1874 to 1914.
Fast forward to 2010... Governing Body member Anthony Morris III (in the DVD "Faith In Action") stated: "The fact that they (the Bible Students) were able to pinpoint that year is just phenomenal" giving credit to the Bible Students for the 2,520-year calculation even though it really originated with John Aquila Brown and NOTHING that was predicted by the Bible Students actually came true. This DVD even states on TWO (2) occasions that the Bible Students looked to 1914 decades in advance as the year that Jesus would return. Obviously, this is completely and utterly false as is plainly evident in WT publications printed before the 1920's.
