On pgs. 66, 69, 211, 423, 560, 648, and 719 of Jehovah's Witnesses--Proclaimers of God's Kingdom, reference is made to The Finished Mystery, which was the 7th of the Studies in the Scriptures series published by the WTS in 1917 (pg 66, 719), and was the major publication of the WTS at that time. On pgs. 88, 648, and 651, a picture of this book appears, complete with the winged disk symbol of the Egyptian sun god Ra on its front cover. Is it true that The Finished Mystery taught that Christ was the Almighty of Rev 1:8 (pg 15), that Christ established a "Church" (pg 17), that Christ returned invisibly in 1874 (pg 54, 60, 68). that the Holy Spirit has a personality (pg 57), that the great pyramid of Giza was God's stone witness and was used to predict the year of Armageddon (pg 60), that Armageddon would definitely occur in the spring of 1918 (pg 62), that Christ was crucified (pg 68), that Leviathan of the Bible refers to the steam locomotive (pg 85), and that Michael is the Pope of Rome and the angels are his bishops (pg 188)? According to "current" WTS teachings, Christ returned invisibly in 1914 and in 1918 chose the WTS as his earthly organization because they were the only ones teaching "the Truth". If this was so, then Jesus would have known the teachings of the WTS as put forth in The Finished Mystery, published in 1917. Do you really think that Jesus would have chosen an organization which taught so many things that were not correct according to "current" WTS teachings and are no longer taught as "the truth"?
When Jehovah's Witnesses are confronted with this type of question from a Catholic who is obviously familiar with the early writings of the Watchtower it might be wise to reverse the question and have them consider some of the idiotic teachings and practices of Catholicism that demonstrably come straight from Babylon. Perhaps ask them to account for the millions of people who have been murdered by the Vatican through incessant wars, like the Crusades and religious wars against Protestants; the torturing and flailing of "heretics" and those who dared to translate and publish or even read the Bible. Could God possibly have anything to do with an organization that makes deals with dictators and tyrants and shares the loot with plunderers? Get real!
