Interestin to see the differences in the outlandish claims :
The finished mystery on page 144 said they were chosen in 1879 and that it was the CORPORATION that was chosen.
8:3. And another angel.-Not the "voice of the Lord,"
mentioned in the preceding chapter, but the corporate
body-the WATCH TOWEB BIBLE AND TBACT SOCIETY, which
Pastor Russell formed to finish his work. This verse shows
that, though Pastor Russell has passed beyond the veil,
he Is still managing every feature of the Harvest work.
"The WATCH TOWEB BIBLE AND TRACT SOCIETY IS the
greatest corporation In the world, because from the time
of Its organization until now the Lord has used it as His
channel through which to make known the Glad Tidings.'*
-Z.17-22; Rev. 14:18; 19:17.
Watchtower 1919 April 1 p.6414
...Is not the Watch Tower Bible and Tract Society the one and only channel which the Lord has used in dispensing his truth continually since the beginning of the harvest period?
Watchtower April 1, 1920, pp.100, 101
We would not refuse to treat one as a brother because he did not believe the Society is the Lord's channel. If others see it in a different way, that is their privilege. There should be full liberty of conscience.
Watchtower 1933 May 15 pp.154-155
Surely Jehovah has an organization on earth, because everything with him is done orderly. For many years he has used the Watchtower Bible & Tract Society. There is but one class of people that are doing his work on earth today and these we call "the Society", acting under the direction of the Watchtower Bible & Tract Society and putting forth the Watchtower publications.
(The emphasis changed in 2001. You'd have to read the whole thing (it's only short) but this is the essence of it:)

... Making a very significant point, Brother Barr stated: "'The faithful and discreet slave' and its Governing Body have had entrusted to them interests that are higher and far more encompassing than those granted to legal corporations. Set out in the chartered purposes of each of such entities are matters that are limited in their scope. Our Master, Jesus Christ, however, has appointed the faithful slave class over all his 'belongings,' or Kingdom interests here on earth."-Matthew 24:45-47. ...
... Brother Barr told the audience that recently certain members of the Governing Body of Jehovah's Witnesses who had been serving as directors and officers voluntarily stepped aside from the boards of directors of all the corporations used by "the faithful and discreet slave" in the United States. Responsible brothers of the other sheep class were elected as replacements.
This decision is beneficial indeed. It allows members of the Governing Body to spend more time in preparing spiritual food and in otherwise caring for the spiritual needs of the worldwide brotherhood.
In conclusion, the chairman told his delighted audience: "While various legal and administrative duties have been assigned to experienced overseers, . . . all of them serve under the spiritual direction of the Governing Body ...
(Also see p. 28f., "How the Governing Body Differs From a Legal Corporation" in the same issue.
You'll notice that since the 2000s, occurrences of "the Society" have dropped drastically from previous decades).
So, in 1919 when they were "chosen" they thought Jesus was choosing a Legal Corporation. By 2001 they thought differently, it was now all the Anointed, inc. the GB, were appointed over Christ's "Belongings", and as we know this has all changed as of recently, as contained in the July 15 2013 WT.
If they got it so wrong in 1919 and 2001, what confidence can JW's have that they have it right now ?
