For those on the board who are more familiar with WTS history than I am:
The WTS claims that one of the marks of the true Christian faith is door to door preaching. They even claim that Jesus and his disciples preached door to door. Let's leave the claim about Jesus and his disciples aside for now and focus on the modern era.
1. Did Russell's Bible Students preach systematically door to door? If so, when did they start?
2. If not, when did the WTS start doing so?
3. Before Russell or the WTS began door to door preaching, what group or organization was preaching "the good news" in this fashion?
4. If the answer is "none," then how is this consistent with the WTS' claim that there were true Christian worshipers of Jehovah throughout all the centuries from Jesus' day to the present?
