I've heard that placing literature written by CT Russell in the door to door ministry would constitute apostasy. At the very least a publisher would be D'Fd if they did so. I mean there are books written by CT Russell that are so off the wall that your head spins. The real reason here is that that old WTS literature is the very ammunition of apostates
Let's proceed to the Rutherford era. He also wrote some books. Again I think the WTS would recommend against placing his literature in the door to door ministry. So what about the Knorr era? I think that the book "Babylon the great has fallen - God's kingdom rules" is from this era. Well can we place that book in the door to door?. I think this is somewhat of an embarassment to the WTS as the dates of 1914,1919,1931,1935 are stressed so much that the WTS can't go back and change these dates. Imagine the supreme arrogance in saying that the door to heaven was closed in 1935. Do you think the householder in the door to door work would fall for that lie.? Not only that but that book is largely a bunch of quotes from Rutherford (Russell is only mentioned once)
Proceed to the Franz era..The book "The aid to bible understanding" was written by an apostate - our good friend Raymond Franz. The question now is what older literature will the WTS allow to be placed in the door to door work.??
