While not pre-1914.... 1932's Preservation pg 193, 194 (Rutherford) had a nice little 'gem' :
"By his spirit, the holy spirit, Jehovah God guides or leads his people up to a certain point of time, and thus he did until the time when "the comforter" was taken away, which would necessarily occur when Jesus, the Head of his organization, came to the temple and gathered unto himself those whom he found faithful when he, as the great Judge, began his judgment, in 1918."

Why is this 'relevant' in our time..... simply because it is true that Rutherford is more our 'founder' then Russell and all of his 'interpretations' were done so under the alleged influence of 'angels' rather than holy spirit.
This of course explains why we have a different truth or gospel than traditional Christendom. We even say so directly in the 1981 WT
w81 5/1 p. 17 par. 3 If God Has an Organization, What Is It? ***
3 Let the honest-hearted person compare the kind of preaching of the gospel of the Kingdom done by the religious systems of Christendom during all the centuries with that done by Jehovah’s Witnesses since the end of World War I in 1918. They are not one and the same kind. That of Jehovah’s Witnesses is really “gospel,” or “good news,” as of God’s heavenly kingdom that was established by the enthronement of his Son Jesus Christ at the end of the Gentile Times in 1914.
You can follow up by asking him to read Gal 1:6-9 from the NWT!
(Galatians 1:6-9) 6 I marvel that YOU are being so quickly removed from the One who called YOU with Christ’s undeserved kindness over to another sort of good news. 7 But it is not another; only there are certain ones who are causing YOU trouble and wanting to pervert the good news about the Christ. 8 However, even if we or an angel out of heaven were to declare to YOU as good news something beyond what we declared to YOU as good news, let him be accursed. 9 As we have said above, I also now say again, Whoever it is that is declaring to YOU as good news something beyond what YOU accepted, let him be accursed.
To review..... WT 'gospel' not Christ impaled (1 Cor 1:23) rather Christ enthroned in 1878 1914, this revelation was not under the guidance of 'holy spirit' but of Angel(s).
I also suggest anything prior to 1922 , the FInished Mystery 1917 edition is a nice read....I believe the archive one is 1918 but has the 1917 pages at the end of the pdf!
