Is the Watchtower Bible and Tract Society an inspired prophet of God or not?
Yes: They claim to be prophets of God.
“So, does Jehovah have a prophet to help them, to warn them of dangers and to declare things to come? These questions can be answered in the affirmative. Who is this prophet?…This “prophet” was not one man, but was a body of men and women. It was the small group of footstep followers of Jesus Christ, known at that time as International Bible Students. Today they are known as Jehovah’s Christian witnesses….Of course, it is easy to say that this group acts as a “prophet” of God. It is another thing to prove it.” Watchtower April 1, 1972 Page 197
No: They deny that they’re inspired.
“However, the Watchtower does not claim to be inspired in its utterances nor is it dogmatic. It invites careful and critical examination of its contents in the light of the Scriptures.” Watchtower August 15, 1950 Page 263
Two Questions.
1). How can you claim on one hand to be a prophet of God, and yet deny being inspired?
2). If the Jehovah’s Witness organization is an inspired prophet of God, then how do you explain the countless false prophecies and doctrinal flip-flops made by a supposed “inspired” organization? If it is not inspired, then what is the final authority for the rank and file Jehovah’s Witnesses?
