What do you mean by that? I was never taught the word parousia. It wasn't in the literature when I studied. Granted I know the word now, but that is for different reasons, because parousia proves them wrong not right.
Anna, thanks for asking that question!
Director Alfred Hitchcock described something he called MacGuffin,
"I mean the emptiest, the most nonexistent, and the most absurd plot device - the mysterious object in a spy thriller that sets the whole chain of events into motion or purports to EXPLAIN without really doing so."
Charles Taze Russell made use of a MacGuffin (parousia) to move his theology out of trouble.
Here is what happened.
In his early twenties, Russell was heavily influenced by the Adventist movement, begun by William Miller, who had predicted that Christ would return in 1844. This was the origin of one of the trademark JW characteristics: the creation of fanciful biblical chronologies and date-setting. Miller himself admitted that his chronology had failed (which was indeed self-evident after 1844). A number of his followers, however, rationalized the failure by inventing a doctrine of Christ’s invisible return.
Russell, who began to lead, in 1870, a Bible study group which evolved into today’s Jehovah’s Witnesses, repeated this unfortunate practice. He wrote in 1881 about the speculations of his short-term partner, Nelson H. Barbour, an Adventist from Rochester, New York, who had originally predicted the physical return of Christ in 1874:
. . . When 1874 came and there was no outward sign of Jesus in the literal clouds and in a fleshly form, there was a general re-examination of all the arguments . . . It was soon discovered that the expectation of Jesus in the flesh at the second advent was a mistake . . . that Jesus was quickened or made alive in spirit . . . Though the manner in which they had expected Jesus was in error, yet the time . . . was correct, and that the Bridegroom came in the Autumn of 1874. (Watchtower, Oct/Nov 1881, 3)
Russell and his followers agreed with Barbour’s original prophecy and explained its failure by transforming the Second Coming into an “invisible presence,” as is evident in Russell’s later account:
As we look backward, we can see that our pathway has been . . . progressive . . . A new view of truth can never contradict a former truth . . . Bro. Keith (one of our contributors) was used of the Lord . . . His surprise was, at finding that the Greek word parousia, which signifies “presence,” had in our common version been improperly rendered “coming” . . . Can it be possible that Jesus does not come in a fleshly body at his second advent? . . . Examination revealed the fact that Jesus since his resurrection is a totally different being from the Jesus who died . . . he is no longer a natural, but a spiritual body. (Watchtower, February 1881, 3)
Russell discussed biblical chronology with Barbour at length in January 1876 and adopted the view which he held until 1914, namely, that Christ returned invisibly in 1874, that the rapture of the church would occur in 1878, and that the dawn of a golden age would commence in 1914 (see section III). He wrote his first booklet, The Object and Manner of Our Lord’s Return (published by Barbour) in 1877. It set forth the doctrine of the invisible “presence” without delving into dates.
About 1930, Rutherford moved the “Parousia” from 1874 to 1914. He made this change about 16 years after the supposed Parousia had taken place.
