You would think that they were predicting the fall of Babylon based on this quote. But what did The Finished Mystery actually say about this?
*** The Finished Mystery 118-9 ***
And it was said unto them.— Not actually, but by the teachings of the parallel dispensations, which show that as Christ was raised from the dead in A. D. 33, the sleeping saints would be raised 1845 years later, in the Spring of 1878. See Rev. 3:14, 20.
That they should rest yet for a little season.— Greek Chronos, 360 years. See Rev. 2:21. This is the item which Pastor Russell had in mind in the following footnote: "When, in a succeeding volume, we examine the wonderful visions of the Revelator, it will be clearly seen that the time here pointed out by the word ‘henceforth,' as marked by events, synchronizes closely with 1878, as indicated by the prophecies herein noted." (C241.) Luther nailed the proclamation on the church door at Wittenberg Oct. 31, 1517, which was already one month into the year 1518, Jewish reckoning. But it took some time for the news to travel to all parts of Europe. Three hundred and sixty years from the Spring of 1518 brings us to the Spring of 1878, when we understand that God's promise made to the sleeping saints was fulfilled. They were raised from the dead, and Babylon was cast off.
*** The Finished Mystery 226 ***
[Ezechiel] 14:16. And He that sat on the cloud.— The Lord Jesus, during His Parousia, overruling and withholding the Time of Trouble.Thrust in His sickle on the earth; and the earth was reaped.— Reading verses 13-16 connectedly, we note that the resurrection of the sleeping saints is recorded, and is immediately followed by the Harvest. This suggests that the Harvest proper began in 1878; and that the three and a half years prior to the spring of 1878 was devoted to preliminary work, but not to Harvest work in the full sense. It was not proper to say "Come out of her, My people," until Babylon was cast off, in the Spring of 1878.— Rev. 3:14; Matt. 13:30; 24:31.
*** The Finished Mystery 273 ***
Saying, [Babylon the great is] fallen, is BABYLON THE GREAT [fallen]. — "The expression, ‘ Babylon is fallen,' indicates that at some time a sudden and utter rejection is to come upon Babylon, when all favor will forever cease, and when judgments will follow — just such a rejection as we have shown was due in 1878." — C155; Isa. 13:19-22; 21:9; Jer. 51:8-13; Rev. 14:8; 16:59.
