The thread title is slightly misleading due to the definition of the term "minister". By biblical standards all Christians are ministers of God - it was only later that the term "minister" came to be representative of a Pastoral role within a church. So in the most absolute sense of the term, all Christians, regardless of gender or education, are ministers already.
But I guess the thread starter is asking more directly about pastors and preachers. In this case, we have the two quotes which were given in the first post (which are both from the New Testament, not the Old). First, 1 Corinthians 14:34. It is helpful to remember the cultural standing that women had in this society. Most were not permitted to go to the Synagogue to be taught by men, so their knowledge of the Old Testament was virtually non-existent - this was a cultural influence, not biblical, and unfortunately was how things were in those days. The early Christian church gave women unprecedented Rights, one of these being they were able to attend church gatherings alongside the men. But because of their lack of knowledge, the early church was also plagued by the women interrupting talks and dissertations because they did not have the background understanding of the Old Testament that the men did. As a result of this, Paul tells them not to interrupt during the service because it interrupts other people from learning and gaining more knowledge. Instead, if you have a question, ask your husband at home (I noted that you didn't quote verse 35 straight after this, which says "
If they want to inquire about something, they should ask their own husbands at home; for it is disgraceful for a woman to speak in the church." Indeed it was disagraceful for them to interrupt other people, but this was no fault of theirs, they simply did not have the knowledge base that the men knew already.
It would be akin to somebody who had never heard about Christianity walking into a church today, listening to the Sermon, and every five minutes putting their hand up and saying
"Excuse me, could you explain what you mean by statement x?" It would be a disgrace, because they indeed are interrupting everyone else who are trying to listen and have already heard the basics - instead, this person should keep quiet, and ask questions afterwards in an appropriate manner at a time that is not disruptive.
In the same vein is written 1 Timothy 2 (the other passage quoted). Paul writes that women are not allowed to teach. This is partly due to the aforementioned cultural understanding. Women simply did not have the knowledge base to be able to teach the men. This wasn't their fault, but society. Society had put them in a position where they didn't have the required knowledge to teach others (men). Would you let a Truck driver lecture in University about Particle Physics when the truckie had never even heard that term before? Of course not! Then how could a woman in this period of history teach men, when it was the men who had the knowledge and the women did not!!!! Paul's warning not to let women teach was quite understandable for the time.
That said, I know from here on in I'll probably be slammed for my beliefs, but I still believe these statements are applicable today. While women can have great influence in the Church, given many responsibilities, I believe that the job of the Pastor (which encompasses far more than simply Preaching once a week in a pulpit) is ultimately decreed by God to be for men. That does not mean that a woman is useless, or less than men, but rather that God has given us different roles within the Church. The role of the Pastor (what the Bible would probably call the "Overseer") is for men. Other roles can be for men and women, and women can indeed be a great influence and treasure for all the Church. When it comes to discipleship (mentoring/teaching others in a one-on-one setting) men should disciple other men, and women should disciple other women. Men should not disciple women, and that goes for the Pastor as well - he should not disciple a woman because that is not his Role. All people within the body of Christ (believers) have their roles to play, and just because a woman cannot biblically be a pastor, that doesn't make them inferior nor does it mean that they can't do anything - there are many roles within the Church, and in the end, no one is superior to anyone else, because just as Jesus Christ, all Christians are servants to each other, no one superior - all one, in Christ.
Hopefully this makes sense
