Well, Hello!
I must say that I am somewhat impressed. You actually took the time to provide some sort of proof that the Watchtower Society was indeed selected by Jesus Christ in the year 1919 C.E.. You are unlike my wife who, when confronted with this question, will resort to questioning my motives or my character in some sort of fashion. You certainly get an A for effort.
BUT...
I do not see any verifiable facts to prove all of your assertions. Rejected false teachings like the Trinity and the immortal soul? Based on what? You can't say the Bible because I can pluck scriptures to argue for these beliefs just as easily as I can pluck scriptures to argue against these beliefs. Tainted by Babylonish practices? Do you perhaps mean the pyramidology and the belief that Christ began reigning invisibly in 1874? Who amongst Christendom was teaching that save for the Second Adventist in regards to the 1874 teaching.
You then go on to speak about Rutherford and others being arrested and later released. How does this prove that Jesus selected them in 1919? Why were they arrested in the first place? Then they were released "to the chagrin of their religious enemies." What enemies? The 'proof' continues to go on about the Bible Students facing their 'relentless enemy,' Babylon The Great. Then goes on to say that 'the facts show that anointed Christians began to enjoy in the year 1919.' What? What facts? Furthermore, don't the Bible Students exist seperate from the Jehovah's Witnesses of today? If so, then assuming that this whole 1919 selection is even remotely true, perhaps it was the Bible Students that was selected and not the Jehovah's Witnesses.
Do you have anything that I can independently verify? Thanks for your effort, keep trying.
