Dan, you wrote,
the fact that God's servants have misunderstood Jehovah's timetable shouldn't undermine our trust in Jehovah's Organization.
That's absolutely right in an abstract kind of a way. The reason Jehovah has an organization on earth is so he can see his will in print and he only would appoint a printing business that would change the writing when it was wrong. God works through men and he only can pick imperfect men who can pick printing equipment to print 25 million copies of The Watchtower monthly in 146 languages and Awake! which has a monthly circulation of 22 million copies in 86 languages with single-web systems in 64-page configuration that can operate at speeds up to 45,000 cylinder revolutions per hour. Those brothers are much too busy managing those presses and maintenance of the buildings to spend much time on timetable calculations. It's unreasonable to expect Jehovah's Organization to be responsible for erroneous conclusions some brothers may have come to from reading the books and magazines provided by the Faithful And Discreet Slave.
It's much easier to buy seven LITHOMAN presslines from MAN Roland, to be installed in its printing plants in England, Mexico, Brazil, South Africa, Japan (one press each) and the USA (two presses), with delivery of the order running in the middle of tens of million Euros, than to get religious doctrine correct since Jehovah is blessing the expansion of the Worldwide printing but the writing department never claimed to be inspired.
The timetable thing is critical to understand because after the donation of wills and trusts and brokerage accounts the focus is on the printing of the good news, which is mostly made up of bad news, and the brothers handling the cash are in no way connected to those who were mismanaging the timetable department.
