Here's some other snippets from the WTS. concerning the two different dates.
"THE SCRIPTURES SHOW" JESUS RETURNED IN 1874
From 1876 Charles T Russell who founded the Watchtower Society – the publishing/legal channel of the Jehovah's Witness sect – promoted 1874 as the date for Christ's return and the start of Christ's "invisible presence".
That Christ returned in 1874 was official doctrine until 1930:...the Bridegroom came in the Autumn of 1874, and he appeared to the eyes of faith – seen by the light of the lamp – the Word. (Zion's Watch Tower Reprints October/November 1881 p. 289)
Our Lord's presence as Bridegroom and Reaper was recognized during the first three and a half years, from A.D. 1874 to A.D. 1878. Since that time it has been emphatically manifest that the time had come in A.D. 1878 when kingly judgment should begin at the house of God. (Studies in the Scriptures Vol. II 1889 p. 239)
…he [Jesus] would in reality assume the kingly office, power, etc.; viz., in the spring of 1878, three and a half years after his second advent at the beginning of the harvest period, in the fall of 1874. (Studies in the Scriptures Volume III 1891 p. 234)
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: and the formal inauguration of his kingly office dates from April 1878, A.D. (Studies in Scriptures Vol. IV 1897 p. 621)
Pastor Russell...believed and taught that we are living in the time of the second presence of our Lord, and that his presence dates from 1874... (WT December 1, 1916 p. 5998)
Fall 1874 A.D. Second Advent of the Lord. (The Finished Mystery 1917 p. 60)
Some of the Scriptures, which, when understood in their connections and significance, prove that the Lord's Second Advent occurred in the Fall of 1874 are as follows: [A list of 88 interpretations followed] …and these are but 88 of the proofs hastily collected. (The Finished Mystery 1917 pp. 68, 71)
The time of the Lord's second presence dates from 1874... (The Harp of God 1921 p. 231)
The Scriptures show that the second presence (of the Lord) was due in 1874... This proof shows that the Lord has been present since 1874... (WT March 1, 1923 p. 67)
Surely there is not the slightest room for doubt in the mind of a truly consecrated child of God that the Lord Jesus Christ is present and has been since 1874. (WT January 1, 1924 p. 5)
The second coming of the Lord therefore began in 1874... (Creation 1927 pp. 289, 291, 297, 298, 318)
The Scriptural proof is that the second presence of the Lord Jesus Christ began in 1874 A.D. (Prophecy 1929 p. 65)
From 1874 onward is the time of the Lord's second presence, as above stated… This circumstantial evidence fulfilling prophecy is what constitutes the physical facts, and is proof corroborative of the Lord's presence since 1874… His presence beginning in 1874, he has carried on his harvest work from 1874 forward… (Our Lord's Return 1929 pp. 27, 33, 37)JESUS' "RETURN" SWITCHED FROM 1874 TO 1914
In 1930 Christ's return and "presence" was switched from 1874 to 1914.
In The Golden Age magazine (1930 p.503) Joseph Rutherford, the second president of the WTS, wrote "Jesus has been present since 1914" but he gave no supporting explanation. In 1932:The prophecy of the Bible, fully supported by the physical facts in fulfilment thereof, shows that the second coming of Christ dates from the fall of the year 1914. (What is Truth? 1932)
Until 1943 there was little further mention of this doctrinal change. Then in 1943 the WTS published The Truth Shall Make You Free which revised the WTS's Bible chronology by bringing the date of Adam's creation 100 years forward. This removed any remaining prophetic significance of 1874. Christ's return in 1914 thus became the official truth for Jehovah's Witnesses (JWs).
After switching Jesus' "return" from 1874 to 1914 the WTS writers began to claim or imply that their early Bible Students had anticipated 1914 as the date of Christ's "presence" from their beginnings!
Consider some examples:
DECEITFUL CLAIM REGULARLY REPEATEDAs for the time of Christ's second presence, Daniel's prophecy is again the one that gives the chronology for it. (Dan. 4:16) It was figured out as pointing to A.D. 1914, and The Watchtower called notice to the significance of 1914 in the year 1879. (WT1952 November 1, p. 658)
Why, then, do the nations not realize and accept the approach of this climax of judgment? It is because they have not heeded the world wide advertising of Christ's return and his second Presence. Since long before World War I Jehovah's witnessespointed to 1914 as the time for this great event to occur. (WT 1954 June 15 p. 370)
Bible chronology also fixes the time for Christ's second presence and the assuming of his right to rule as at 1914; this date was published in the Watchtower as early as 1879, 35 yearsbefore 1914. (Tract: Sign of Christ's Presence 1955 p. 3)
…history confirms that Jehovah's witnesses were the only Christian group found awake as to 1914… (WT 1960 July 15 p. 433)
As we look back over the years, we can clearly see how God's organization in modern times has progressed in understanding. For example, it learned that Christ's second presence was to be in the spirit, and not in the flesh as many professed Christians believe. His rule would be from the heavens. This was a new revelation of great importance to God's people who had been anxiously awaiting his second presence toward the end of the nineteenth century. (WT1965 July 15 p. 428)
For over thirty years before that date and for half a century since, Jehovah's witnesses have pointed to the year 1914 as the time for the end of "the appointed times of the nations" and the time in which Christ would begin his Kingdom rule.(Luke 21:24) (WT 1966 February 15 p. 103)
"Do you believe in the second advent of the Lord?" I asked the young man [a WTS colporteur in 1928] who came to the door. "Christ's second advent was realized in 1914" he answered. In astonishment, I told him that was impossible. "You should read this book," he said, handing me The Harp of God. I was baptized the following year, March 23, 1929... (WT 1988 May 1 p. 22)
[Note: Nowhere in The Harp of God (1921) is the "second advent" of Christ put in 1914. On the contrary, 1874 as the date of the "presence" of Jesus is mentioned in The Harp of God on pages 230, 231, 234, 235, 236, 237 241, 244, 271). Also "the young man" could not have known in 1928 that "Christ's second advent" was realized in 1914" because that teaching had not been published at that time! Even the later editions of The Harp of God (1937 & 1940) retained 1874 as the date of Christ's "presence".]
He [a WTS colporteur of 1921] explained to me that Jesus had been present since 1914, invisible to man. This was the most thrilling news I had ever heard... In late 1921 I was transferred back to England, and in the spring of 1922, I was discharged from the army. (WT l990 September 1 p. 11) [Note: When this purported conversation occurred in 1921 no WTS publication had mentioned 1914 as the date for the "return of Christ'' – nor for nine years afterwards!]
The Watchtower has consistently presented evidence…that Jesus' presence in heavenly Kingdom power began in 1914. Events since that year testify to Jesus' presence. (WT 1993 January 15, p. 5)
…a prophecy providentially caused sincere 19th-century Bible students to be in expectation. By linking the "seven times" of Daniel 4:25 with "the times of the Gentiles", they anticipated that Christ would receive Kingdom power in 1914. (WT 1998 September 15 p. 15)
IGNORANT DUMB DOGS REJECT 1874
So certain was the 1874 date still in 1929 that Rutherford, the WTS's second president, warned against ministers who disagreed with that date as follows:Paul was a real Christian. He was not a D.D., unable to understand, such as are the D.D.'s of this present time. (Isaiah 56:10, 11) Here the prophet says that some who claim to be watchmen will be blind and ignorant; and that these would be ‘d-d-s, sleeping and lying down, loving slumber'. He then says that they are greedy, never able to get enough, shepherds of congregations that can not understand; that they look out only for themselves, to get gain from their own congregations. (Our Lord's Return 1929 p. 21)
To followers of Rutherford the abbreviation "D.D." or "d.d." meant dumb dog but was also a pun on "Doctor of Divinity". The pun was a Rutherford joke for 25 years:[C T Russell]…had too much of God's work to do to pay attention to the yelpings of little men – of the D.D's of Christendom (Isa. 56:10), who love slumber, but who snarl and bite when disturbed in their dreams of "peace, peace" (Jer. 6:14), social and civic gospels, church unity, and evangelistic raids on the pockets of the masses. (The Finished Mystery 1917 p. 383)
Consolation magazine (1940 March 6 p. 24 Australian edition) carried the joke further with a photo of a dog wearing a sign advertising a Rutherford lecture. The caption to the photo is "NOT A DUMB DOG".
Pastors, church ministers and Doctors of Divinity were people most likely to demonstrate the nonsense of Christ's return in 1874. Hence the booklet Our Lord's Return – prior to discussing 1874 in detail – disposed of them as "blind", "ignorant" and "D.D.'s"
Incidentally, thousands of anti-church comments like the above between 1917 and 1942 – mingled with ever-changing doctrines all labelled "truth" and with self-praises such as "peaceful Christians", "saintly", "watchful", "enlightened", etc – were leading causes of persecution of JWs during that era. But that's another story. Here the quote regarding "D.D.s" is used to show how certain the 1874 date still was in 1929.
WHAT WAS PREDICTED FOR 1914?
The early JWs or Russellites did preach about 1914 but not as the date for Christ's "invisible presence" since that, to them, occurred in 1874. What they did predict for 1914/1915 is that they themselves would ascend to Heaven, the world's nations and religions would be destroyed, and the survivors would be ruled by the Old Testament heroes like Abraham who would be resurrected and live in Jerusalem! For example:Be not surprised then, when in subsequent chapters we present proofs that the setting up of the Kingdom of God is already begun, that it is pointed out in prophecy as due to begin the exercise of power in A.D. 1878, and that the ‘battle of the great day of God Almighty' (Rev. 16:14) which will end in A.D. 1915, with the complete overthrow of earth's present rulership, is already commenced. (Studies in the Scriptures Volume II, 1889, p. 101)
And with the end of A.D. 1914, what God calls Babylon, and which men call Christendom, will have passed away, as already shown from prophecy. (Studies in the Scriptures Volume III, 1891, p. 153)
JWs ADMIT MISTAKES
WTS writers sometimes publish "recollections" of aged JWs – like the two above. Their reminiscences – that in the 1920s it was taught Christ came in 1914 – are false. Historically the things "remembered" are anachronisms and could not have happened. Anyone who taught in the 1920s that Christ returned in 1914 would have been expelled and shunned for apostasy!
WTS publications say that JWs admit mistakes:Be big enough to admit a mistake…In striking contrast to the position taken by the popes is that taken by the Christian witnesses of Jehovah. They readily admit to having made mistakes as to doctrine and worship. (WT 1972 November 1 p. 643-644)
JW Leaders publish lies about what was predicted for 1914, yet boast that the early followers were correct regarding 1914 even though they were wrong, and then boast again that JWs "readily admit…mistakes" when in fact they don't readily do so! That's why this article is called "Boastful Lies".A religion that teaches lies cannot be true. (WT 1991 December 1, p. 7)
