promptly disfellowshipped prominant elders for saying the door to door preaching work was unnecessary in the 1970s.
As commented on in CoC, the real issue was some JWs had a problem with the meaning that WT attached to door to door activity, namely, 1) claiming this is how Jesus and the early disciples preached, therefore it's a requirement for Christians today, and 2) how hours and placements are used as a judging tool. More hours/placements = more "spiritual".
D to D is one method of eveangelizing, but certainly not the only method nor scripturally mandatory.
It's typical WT rhetoric, start first with the doctrine, then make everything fit, rather than actually determine what the Bible says first, then formulate a doctrine.
DD:
Nothing is truly discussed. A symposium is a fast regurgitation of JW " factoids " to be accepted as "truth."
Exactly. Conventions offer nothing different than what a JW can hear at any meeting during the week. "Progressive" = repetition ad nauseum in WT Land.
