Initially, Russell taught that the Harvest of the "elect," an elite group that
included himself and whoever agreed with everything he said (which would be a
little group) was to last until 1881, although that date changed as time went
by. Russell eventually specified that the elect, otherwise called the "little
flock," was the 144,000 of Rev.14:1-5 taken literally to be 144,000 followers.
("Watchtower Reprints," 1881, p.224; 1880, p.172)
1880 Russell taught that the 144,000 of Rev.14:1 are the "little flock" he's
part of, not those of the "nominal church" of corruption, by which he meant most
all other Christians. "Christendom" isn't a derogatory word unless it's meant
that way, and he meant it that way. (Practically none of them taught a created
Jesus you worship, let alone when he invisibly appeared, etc.) The ability to
join the 144,000 would end in Oct., 1881:
"Dearly beloved, if we believe these things, our works will attest our faith.
If you and I believe that the door to the 'high calling' closes in less than a
year, should we not increase our efforts to bring all Christians into the light
of present truth--the knowledge of the bridegroom's presence--that they and we
may be more fully separated from the world." ("Watchtower Reprints," Nov., 1880,
pp.155,156,172)
1914 "The evidences seem to be that there are still quite a number of vacan-
cies in the elect number, because there are people coming into Present Truth and
consecrating who have come directly from the world. This would seem to indicate
that there are not at present a sufficient number fully consecrated to complete
the 144,000. If there were, these would be given the preference over those not
consecrated." ("Watchtower Reprints," March 1, 1914, p.5411)
1916 Russell taught that the ability to join the alleged literal 144,000
would end in "perhaps a year or two or three." "...we anticipate that before a
very long time--perhaps a year or two or three--the full number of the Elect
will be completed, and all will have gone beyond the Veil and the door will be
shut." ("Thy Kingdom Come," forward to 1916 edition, pp.i,ii)
Russell played prophet whether he claimed any contact with angels, or admitted
it or not, on any one occasion, by pretending to be the spokesman for a literal
144,000. The things he meant to justify the exclusiveness (and damning others)
included things like New Earth creationism, a created Jesus who was to be
worshiped for 1st cent. Jewish monotheism, when Jesus invisibly appeared and
would visibly appear, pyramidology, etc. The movement may have gotten even
stricter with Rutherford, but the phoniness started with the claim of being the
spokeman of a literal 144,000, and having to cook things up for the pretension
of exclusiveness, which started with Russell.
