I believe Morgan Edwards in his
Customs of Primitive Churches (1768) took the position that only the male members could vote. I'll have to double check to be certain.
We studied this issue back in the 1980s in our church. There were questions about it. We came to the conclusion that women could/should vote in conference.
The biblical examples of congregational decisions illustrate that the women took part. Acts 1:12-26 records the selection of one to fill Judas’ office. The assembly was made up of about 120 people (v. 15), which included women (v. 14). They, the 120, appointed two men, and they,
the 120, gave forth their lots and chose Matthias. So this selection process included the women.
Acts 6:1-7 tells of the selection of the first seven deacons. The seven were chosen by “they” — which refers to the multitude of the disciples (vs. 1,2,5), and this included
widows (who are always women).
In the council meeting of Acts chapter 15, the final decision was made by
the whole church (v. 22), which included women as well as men. We concur from these three examples that the women should vote.
Although the women voted, it was the men who provided the leadership.
