Part of my strategy in talking with current JW's is using the Watchtowers own publications against them. It is not sipmly good enough to show them something wrong in an old publication, you also must show where they covered up or contradicted the particuliar teaching or event in a more rescent publication. A prime example of this is how the Watchtower states that a correct understanding of spiritism must have been understood by the group who became the faithful slave. Notice this rescent quote:
*** w90 3/15 p. 13 par. 18 ?The Faithful Slave? and Its Governing Body *** On arriving to inspect his slaves in 1918, therefore, whom did the Master, Jesus Christ, find giving to his body of attendants their measure of food supplies at the proper time? Well, by then, who had given sincere truth-seekers the correct understanding of the ransom sacrifice, the divine name, the invisibility of Christ?s presence, and the significance of 1914? Who had exposed the falsehood of the Trinity, immortality of the human soul, and hellfire? And who had warned of the dangers of evolution and spiritism? The facts show that it was the group of anointed Christians associated with the publishers of the magazine Zion?s Watch Tower and Herald of Christ?s Presence, now called The Watchtower Announcing Jehovah?s Kingdom. (emphasis added)
So they should have been free from spiritism at this time right? Wrong. The Golden Age Magazine promoted a book that was written by a spirit medium, called 'Angels and Women':
What other contradictions and lies do you know of that exist in the more current publications?
