Their “old light” was that Jesus’ “faithful and discreet slave” appeared in 33 C.E., 1900 years BEFORE Christ’s presence began in 1914.
That interpretation had caused a problem that the Governing Body was never able to satisfactorily explain. They needed to be able to show that there has always been a functioning “faithful and discreet slave” in one form or another ever since.
But they were never able to provide any evidence for the existence of an ongoing “1900 year-old slave” prior to the appearance of the Watchtower Society.
Here is how they finally solved that problem on October 6, 2012…
“The faithful and discreet slave” must have appeared AFTER Christ’s presence began in 1914." *
Now it can easily be explained that the reason why “the faithful and discreet slave” cannot be found BEFORE the beginning of Christ’s “invisible presence” in 1914 is simply because his “slave” did not appear until AFTER Christ’s presence began in 1914.
Will any Witnesses wonder why Jehovah waited 133 years to communicate this simple answer to his channel of communication?
