I don't believe women are called to govern in leadership, so a woman pastor in the traditional understanding that we see the role of a pastor today is unbiblical, in my opinion.
However I do believe women are called to preach and share the gospel, and to teach, and to minister in gifts of the spirit. As a woman disciple of Christ, if I were to engage in preaching the gospel to a crowd of people, it would be under the authority of my husband, and my ministry would be focused to lead and encourage other women.
The reason I believe this is because of the relationship of Christ and the church. Christ being the head, and the church being the body. I believe Paul in
1 Cor. 11 is teaching that as Christ is the head of the church, so the man is the head of the woman. The church never dictates to Christ what to do, so the woman should never dictate to the man - her husband - what to do... however, there is a teamship, and a loving relationship that takes place when each fulfills their duties to each other that allows much to be accomplished. It is in this way I understand as a woman I can minister to the church, and I can teach and/or preach the gospel, but when it comes to leading, and government, that is the role of the man.
I suppose I could also say... let the fireworks begin... but after much prayer and study, I believe that a woman's role in the church is not in government/leadership positions, but to be a helpmate, and support to her husband, keeping in mind the Christ/church relationship.
