sisters are Lieutenants

A Sister can be a Lieutenant? Absolutely, within the congregation. In 1917 some Brothers felt their greatest place was giving talks and doing door-to-door but just leaving literature and if the interested person loved the Lord, they'll attend a class meeting. But Russell wanted to do more. He wanted to start "pastoral work" or return visits and class studies or Bible Studies. Since he was having a challenge getting Brothers he was going to use Sisters, why the Bible says Jehovah will use the stones if need be. One Sister would be put in charge of the "pastoral work" and class studies, and she would be called a Lieutenant, today we call the Brother a Service Overseer. Let's let the "Divine Purpose" book tell the story on page 66.
"Another activity begun before Pastor Russell's death, called "pastoral work, was also stepped up. In Russell's day this work had been limited to about 500 congregations that had voluntarily elected him as their pastor. He had written a letter to these groups describing the work as an "important follow-up work possible in connection with addresses received at public meetings, Drama exhibitions, from colporteur lists, etc ."
This is the way this work was to be carried on: All the sisters in the congregation who were interested in engaging in this work were to elect democratically one of their group to serve as a lieutenant and another to serve as a secretary-treasurer. The city was to be divided into territorial districts assigned to individual sisters engaged in the work to call on all those whose names had been supplied as being interested. The purpose of these calls was to loan books, which could be read and studied by the person of good will, and to stimulate progress in a knowledge of the truth in other ways as well. Careful reports were made as to where interest was manifested, whether the person would attend one of the chart talks, etc . To assist the sisters, suggested approaches in calling at the homes were given, as well as suggestions in regard to overcoming prejudice and obtaining the names of others who might be interested in the message. At the conclusion of the call, the householder was advised that a chart talk on the "Divine Plan" would be given soon in that district. Persons manifesting interest were encouraged to attend these talks and, afterward, follow-up calls were made upon all those attending, with an effort to begin a study in the first volume of Studies in the Scriptures."
When Brother Rutherford took the lead in the work, he continued this arrangement for a time.
