As JWs we learned the utmost central Watchtower doctrine that Jesus returned "invisibly" in 1914 (well it was 1874, but then J. F. Rutherford decided Jesus really, really, really returned at a later date ... this is also known to JWs as "Jesus Second Presence" (Greek: parousia = English: presence):
Ref. related new thread at: http://www.jehovahs-witness.com/6/70098/1.ashx
This teaching, above all others, is the cornerstone of JW theology ... and is based on Charles Taze Russell's exposure to Bible students in Pennsylvania who talked of this "Second Presence" ... it is where Charles got the idea that the reason they (Second Adventist) did not "see" Jesus is that the Greek word "parousia" is not a visible "coming" but an invisible one ... and it is why Jesus left in clouds to conceal his departure, so by George, he must return in a cloudly murkey - hence - invisible manner too ... its all in the Bible ... NOT.
What does "Parousia or Presence" really mean? A fellow engineer I worked with years ago is from Greece. [George Davliakos] ... he is well versed in modern Greek, Koine Greek, Classical Greek, and about every other kind of Greek you can think of ... so, being the good JW that I was, I would often try to witness to George by getting him to comment on Greek as the New World translation goes ... I would drag out the Interlinear, the Diaglott, etc. and he would read it fluently ... then explain translation to me ... btw: George is also fluent is several languages, besides English ... but Greek is special to him.
"George, please tell me about the meaning of "Parousia." Most often, George would agree with how the NWT was translated (the NWT is not always bad) ... he would take exceptions here and there, but they were not too serious ... so, I enjoyed how George validated my JW NWT Bible to some extent at least ... and the times where he disagreed with the NWT, I would ignore it or decide that more research was needed ... but then ... one day ... we discussed that word, parousia.
He said it means - "Coming." ... No, George, you have it wrong, the Greek word "parousia" means "presence" such as being there by being invisible - just like the Society says ... they have Greek translators you know ... No, Jim, you are an idiot for believing that ... Greek no more justifies "invisibility" than does the English word "presence." Neither word has anything to do with "invisibility" ... for that matter, if Jesus is invisible, he can be "coming" invisibly or "present" invisibily ... so the assumption by your religion is wrong ...
He went on to tell me that for nearly two thousand years, Greek speaking Christians have anticipated Jesus "coming" when they read the word "parousia" because to be coming, as you might be approaching a place but everyone sees you coming, or to be there as present, and everyone sees you there is a matter of small difference, almost symantic. No, the Bible says that every eye will see Jesus ... and for that matter, Jesus really left "visibly" before he disappeared ... so, in like manner he returns in his "coming" to emerge from the invisible to become visible ... just as scripture says ...
No George, it is like this, you see ... and I went on to "witness" to him about the ugly truth regarding his native Greek language and how "parousia" really means invisible ... yes, I was the idiot ... a good JW ... but an idiot nonetheless ... now, I understand the real ugly truth about "parousia or presence" ... that it neither requires visibility or invisibility ... the whole CENTRAL DOCTRINE of the Watchtower is based on a Red Herring as is most all of their other teachings.
