This is a contentious issue these days. I believe though that the bible clearly says that a woman is not to preach.
12 And I do not permit a woman to teach or to have authority over a man, but to be in silence. 1 Timothy 2:12
If Paul says he doesn't permit a woman to teach or have authority over the men then he must mean what he says. I'm not sure how you get around that verse.
2 A bishop then must be blameless, the husband of one wife, temperate, sober-minded, of good behavior, hospitable, able to teach; 1 Timothy 3:2
This says a preacher must be the "husband" of one wife. Paul is speaking of a man, and there's not really any indication he could possibly mean otherwise. In the next few verses he reiterates this premise further:
4 one who rules his own house well, having his children in submission with all reverence 5 (for if a man does not know how to rule his own house, how will he take care of the church of God?);
"His own house", "his children", "a man does", "how he will take care". There's no mistaking that Paul is speaking of a man when addressing the qualifications for a bishop. We could say that he simply means pastoring in the general sense, oblivious to the sex---but that's not what the text says. Paul's use of language is casual, as if it is the norm for men alone to be bishops.
I do not say this in a mean-spirited manner; but I think the feminist movement has had an influence on the church over the years. The bible is not politically correct---and that isn't very appealing to some folks.
I always maintain that if you have to stretch scripture, or search for an interpretation that contrasts what the text plainly says in order to give support to a particular doctrine---then the doctrine probably isn't correct. In this case the text says "I do not permit a woman to teach or have authority over a man". There's no deep examination of this text required to support my belief that a woman is not to teach---it says it plainly.
I do not wish to contend with anyone on this issue because churches and Christians have their own decisions to make, and this is simply my own conclusion based on how I read the text. I could be wrong and I'm willing to admit so if I am.
