*** w29 11/1 p. 323 The Day of His Preparation ***
JEHOVAH’s lightnings now make it plain that the periods of time mentioned in the Scriptures as "the day of his preparation" and the time of "preparing the way before the Lord" are not the same. In his own due time God sends his beloved Messenger to prepare the way before him. (Mal. 3:1) That period of time began about 1878 and continued until 1918, and there ended. Thereafter the period of time designated "the day of preparation", as described by another prophet, began, and is still in progress. (Nah. 2:3)
*** w30 1/1 pp. 6-7 Sing Unto Jehovah ***
Prior to 1915 certain of the purposes of Jehovah unfolded and matured, and exactly on time. Some who had made a covenant with the Lord induced themselves to believe that the "faithful and wise servant" of Jehovah was one man, and they take an unwise course accordingly. In consequence they stumble into the error that no truth has been revealed by Jehovah to his people since 1916. Such have not seen the revealed truths that have been given to God's anointed during the past few years and do not now understand present truth...
Former things concerning God’s purposes that did come to pass were understood after the Lord came to his temple and the lightnings of Jehovah illuminated his Word. This same class then see new things which God has declared. In the light of prophecy in the course of fulfilment, and of the further illumination thereof by Jehovah, the remnant class is permitted to see other things that are shortly to follow.
*** w30 8/1 pp. 229-230 A Great Image — Part 1 ***
More than fifty years ago some good, honest Christian people who were called Adventists published an interpretation of the foregoing prophecy of Daniel which in substance states that the terrible image that Daniel saw represented the successive world powers, to wit, Babylon, Medo-Persia, Greece and Rome; that the golden head of the image represented Babylon, the breast of silver represented or pictured the Medo-Persian empire; that the copper (mistranslated brass) pictured the Grecian world power; and the legs of iron pictured the Pagan Roman world power; and the feet composed of iron and clay pictured Papal Rome or what is otherwise called the "Holy Roman Empire". The Watch Tower publications, having no better explanation, practically adopted the forgoing interpretation. There are some good reasons why the above interpretation of the prophecy is not correct...
[T]he true meaning of the terrible image could not be understood by any of those whom Daniel represented until after the coming of the Lord to his temple. The foregoing interpretation having been made long before the coming of the Lord to his temple, it is hardly likely that it would be correct. That would not mean that any criticism is leveled against any of those who thus interpreted it. Without doubt God was pleased with them because they sought the truth. Daniel's prophecy says: "This secret is not revealed to me for any wisdom that I have more than any living, but for their sakes that shall make known the interpretation." And furthermore that 'the God of heaven revealeth secrets of what shall be in the latter days'. (Dan. 2:28, 30) These "latter days" must refer to the "day of the Lord", which means the time beginning when God places his King upon his holy hill in Zion. (Ps. 2:6) That event occurred in 1914, and surely then the understanding could not be had until after that time. It was after the Lord came to his temple in 1918 that his anointed people began to have a better understanding of the prophecies, because the temple in heaven was opened. (Rev. 11:19)
What is ironic about the last comment is that the old pre-1918 view is the one that the Society today teaches; they have abandoned the "new light" that Rutherford here presents as superior to what previously was taught (i.e. Rutherford claimed that the head of gold corresponds to Satan, the silver chest corresponds to Satan's chief angels, the copper corresponds to the lower echlons of angels in Satan's organization, and the legs of iron correspond to the earthly kingdoms of the earth). And then in 1935, Rutherford claimed that this new understanding of Nebuchadnezzar's dream was not due to any human interpretation of scripture, but was revealed directly by Jehovah through the angels, like an "automaton to give utterance to what God had caused to be injected into his mind" (15 February 1935 Watchtower, pp. 51-52). In reality, the whole "Lord coming to his temple in 1918" doctrine was a convenient device to discredit the Russellite teachings he wanted to replace. What is interesting is that in many cases (such as also the "superior authorities" teaching), the "faithful and discreet slave" afterwards went right back to those pre-1918 beliefs that Rutherford replaced. So much for God implanting the new understandings of prophecy in Rutherford's mind.
