Yes. They have already proven they have the capacity to alter doctrine on the flimsiest of Scripture fragment and the congregants gulp it down greedily, despite the poison-laced nature of the waters they consume.
For instance, elders require confessions based on a Scripture directed toward those who are actively and willingly seeking the help of older men.
James 5:13-15—Is there anyone suffering evil among YOU? Let him carry on prayer. Is there anyone in good spirits? Let him sing psalms. 14 Is there anyone sick among YOU? Let him call the older men of the congregation to [him], and let them pray over him, greasing [him] with oil in the name of Jehovah. 15 And the prayer of faith will make the indisposed one well, and Jehovah will raise him up. Also, if he has committed sins, it will be forgiven him.
If it is not a Scriptural requirement for those suffering evil to carry on prayer and it is not a Scriptural requirement for those in good spirits to sing psalms, then how can the last one in the EXACT same context be a Scriptural requirement?
Another glaring example is the identity of the Faithful and Discreet Slave. From the context surrounding Matthew 24:45-47 it seems pretty clear that anyone can prove to be either wise (discreet) or foolish, good or bad, kind and loving or callous and hateful. From 24:45-25:46, Matthew records Jesus making this point in four different ways.
But not in this organization! Jehovah's Witnesses have to make it mean something prophetical and mysterious that only they can understand. More than one thing, for that matter. (1) At this organization's founding it was a single person, the FDS was Charles Taze Russell (who still plagues the JWs from beyond the grave ). (2) Then it became the Society—which was never directly defined in the early years but was distinctly referred to alongside the association of brothers that comprised the Bible Students, meaning that it was something other than the entire association no matter what it was. (3) Then it became everyone who partook. (4) Then it became everyone who didn't lie about being anointed when they partook (how can anyone else tell for sure?).
Currently, the only portion of the Faithful and Discreet Slave that is readily identifiable per doctrine is the Governing Body, who claim to be authorized representatives of the rest of the FDS. Only, the FDS never authorized these men to represent them. The Governing Body is descendant from a usurpation of Corporate control from those Russell left in charge. The original Governing Body was the Corporate leadership, not those who were appointed by the FDS to represent them and certainly nothing to do with holy spirit.
For all practical purposes, the average believing JW has to accept the word of men they have never met that they are the chosen elect who are meant to lead mankind to salvation, the tool that Jesus is using in modern times. And they accept on the basis of three verses that have been interpreted four distinctly different ways within 100 years.
It is no problem to manipulate the mush-minds they have created. The barest excuse of a Scripture will do.
