Bible Note: sigh... okay ... then let me leave you with this:
"We understand these words to imply that in the time of the Lord's presence (the present time--since 1874), through this Antichrist system (one of the principal of Satan's agencies for deceiving and controlling the world), as well as through all his other agencies, the devil will make a most desperate resistance to the new order of things about to be established." - Thy Kingdonm Come 1889 - page 360
again on page 364 of the same book:
"THE Time is at Hand for the establishment of the Redeemer's Kingdom. This is the concurrent testimony of the foregoing chapters. Nothing intervenes. We are already living in the seventh millennium--since Oct. 1872. The lease of power to the Gentile kingdoms must terminate with the year 1914. The great antitypical Jubilee, the Times of Restitution of all things, had its beginning in the year 1874, when the presence of the great Restorer was also due."
In volume four of Studies in the SCriptures he wrote:
"Our Lord, the appointed King, is now present, since October 1874, A. D. according to the testimony of the prophets, to those who have ears to hear it..." - The Battle of Armageddon, 1912 ed., page 621.
These are just a few quotes, in which taught and believed to the day he died in 1916 that the second advent of presence of the Lord began in 1874, the Watchtower after the death of Russel continued to this this which can be seen from the following quotes:
"No one can properly understand the work of God at this present time who does not realize that since 1874, the time of the Lord's return in power, there has been a complete change in God's operations." - "The Watchtower, September 15, 1922, p. 278
"The Scriptures show that his second presence was due in 1874…This proof shows that the Lord has been present since 1874…" - The Watchtower, March 1, 1923, p. 67
"The Scriptural proof is that the second presence of the Lord Jesus Christ began in 1874 AD. This proof is specifically set out in the booklet entitled Our Lord's Return." - Prophecy, 1929, p. 65, 66
In 1943 the date was officially chnaged by the Jehovah's Witnesses to 1914, in their own words:
"It is true that the editor and publisher of Zion's Watch Tower and Herald of Christ's Second Presence calculated that the "presence" or parousia of the heavenly bridegroom began in the year 1874 C.E. ...In the year 1943 the Watch Tower Bible and Tract Society published the book "The Truth Shall Make You Free." In its chapter 11, entitled "The Count of Time" it did away with the insertion of 100 years into the period of the Judges and went according to the oldest and most authentic reading of Acts 13:20, and accepted the spelled-out numbers of the Hebrew Scriptures. This moved forward the end of six thousand years of man's existence into the decade of the 1970's. Naturally this did away with the year 1874 C.E." - God's Kingdom Of A Thousand Years Has Approached. 1973. pp. 206, 209
So as you can see, Russell and his Bible Students believed and taught the second advent began in 1874, the Watchtower and their Jehovah's Witnesses changed the date to 1914.
