Jesus reigning as King since 1878:
The Life-giver is present; and, since 1878, when he took his great power and began the exercise of his authority, none of his members need to sleep. -Thy Kingdom Come, 1891, page 240.
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. It is here that Rev. 14:14-20 applies, and our Lord is brought to view as the Reaper crowned. The year A.D. 1878, being the parallel of his assuming power and authority in the type, clearly marks the time for the actual assuming of power as King of kings, by our present, spiritual, invisible Lord-the time of his taking to himself his great power to reign, which in the prophecy is closely associated with the resurrection of his faithful, and the beginning of the trouble and wrath upon the nations.-The Time Is At Hand, 1902, page 239.
Jesus' Invisible Presence began in 1874:
"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)
"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)
