New Light is the tool Jo Ho's use when a prophesy they have made doesn't happen.
For example, I was born a Witness and for my entire life "The Truth" was that the generation that witnessed the events in 1914 would not pass away until Armageddon came, or the end of this wicked system of things.
From the Watchtower, 2/15/69 page 101:
"However, there are people still living who were alive in 1914 and saw what was happening then and who were old enough that they still remember those events. This generation is getting up in years now. A great number of them have already passed away in death. Yet Jesus very pointedly said: “This generation will by no means pass away until all these things occur.” Some of them will still be alive to see the end of this wicked system. This means that only a short time is left before the end comes! (Ps. 90:10) So now is the time to take urgent action if you do not want to be swept away with this wicked system"
Well, this has all changed now. Basically since most, if not all of that generation is dead, they had to come up with "New Light". The "New Light" on this scripture now defines the generation Jesus spoke of as anyone, of any age who witnessed the things Jesus spoke of, which would occur in the last days.
No more time frame. Armageddon could be 200 or 2000 years away.
The answer to your question is yes, the Jo Ho's believe what ever the Governing Body spews.
EDIT:New Light makes sense if it expands or adds detail to a certain belief. But if it makes what you used to believe no longer the truth and the "New Light" is exactly opposite of the old belief, why would God allow "his chosen people" to believe and preach to others something he knew to be untrue.
The 1914 change up cannot be compared to a baby learning to walk. It's more like a teenager being told that the person he thought was his mother is of no relation and he is really adopted.
If you look at examples of "New Light", they are abrupt doctrinal changes, that usually contradict the "old light"
So can any Jo Ho's explain any new light on this gem, from your own literature?
From: The Nations Shall Know That I Am Jehovah - How? 1971 p. 216:
JEHOVAH’S “SWORD” AGAINST “ALL THOSE OF FLESH”
9 Shortly, within our twentieth century, the “battle in the day of Jehovah” will begin against the modern antitype of Jerusalem, Christendom."
Did I miss something? Isn't the 20th Century over?
There was no new light on this gaff. In fact I think they turned this light off.
How can anyone believe anything they say? Anything could change at any time.
EDIT: MOMMY below has the best answer. The facts concerning the 1914 change up are not Bible based but rather how the Jo Ho's interpret the Bible. The bible has not changed, just the current interpretation....until it suits them to change again.
EDIT: GRNLOW, do you believe the above quote from "The Nations Shall Know That I Am Jehovah - How? "
Is it from the Bible? Would you care to enlighten us?
The Nations Shall Know That I Am Jehovah - How?
VOTS "poo" story is not really a good illustration. A better one would be that "We used to think that rubbing poo on us would make us better, but now we have New Light that says we have to eat it."
"NEW LIGHT" is often just the opposite of "Old Ligtht" or a dratic departure, not an expanded view.
In the "poo to germs" theory it would be an expanded view. In the "Gen of 1914" change up, the belief was totally altered.
