What would you say to JWs as an answer to the claims in that article?
By this (their own) logic, every time the Governing Body makes an adjustment or there is "New Light", It means that they themselves were guilty of having a proud and haughty attitude at some point and the truth wasn't revealed to them for decades.
Despite this, their haughty attitude compelled them to print millions of copies of their misinterpretations and insist that their trusting followers use their own time and funds to blanket the globe with their literature. This literature more often than not, condemned anyone who didn't believe them, to a fiery death at Armageddon.
Later when adjustments were made, they still were too haughty to admit they were wrong and apologize to those who had been mislead by their false interpretations, so to this day, they still aren't able to truly understand the Bible.
How skillfully God has designed the Bible!
Q. If they truly believe this is so, why have they found it so necessary to explain the Bible via their literature for these past 100 years?
A. Because it's big business.
