Maybe you might read about Deborah, there apparently were no men around to usurp.
In Judges 4 Deborah was a judge and prophetess God appointed to lead Israel, and who was with them to lead them against the Canaanites, right?
God used many other examples of strong and faithful women in his word. Some early Christians had women serving as deacons and many served the church through their labors, money and travelling and taking care of the apostles. They did many great works for the Lord in the chrch and still do including teaching children and women. I just believe the role of the pastor as an authority figure in a congregation of men, women and children is best served by a strong God-fearing man. It avoids the all-to-human nature problems that come from jealousy and resentment that makes men feel in a less authoritative role than that which should resemble the one in their family as well. We are given the hierarchical example of wives, being submissive to their husbands, husbands loving their wives as Christ loves the church and Christ being the head of the church.
Submitting yourselves one to another in the fear of God.
Eph 5:22 Wives, submit yourselves unto your own husbands, as unto the Lord.
Eph 5:23 For the husband is the head of the wife, even as Christ is the head of the church: and he is the saviour of the body.
Eph 5:24 Therefore as the church is subject unto Christ, so [let] the wives [be] to their own husbands in every thing.
