Question:

Ok ... so I go to this church that is supposed to be all old-fashioned and everything. The preacher always preaches against contemporary music and that kind of stuff. So whatever. Should a woman lead a choir? should a woman lead a youth choir? should a woman preach? should a woman teach a class of teen guys and girls? when is it ok for a woman to teach? To preach? to lead choirs?

Answer:

That is a great set of questions! Of course, the Bible has the answer!

It seems that more and more churches are compromising on simple Bible truths such as this.

1Ti 2:11 Let the woman learn in silence with all subjection. (12) But I suffer not a woman to teach, nor to usurp authority over the man, but to be in silence.

1Co 14:34 Let your women keep silence in the churches: for it is not permitted unto them to speak; but they are commanded to be under obedience, as also saith the law.

So, the Bible is clear. A woman is to learn in silence in the church. She is not to teach a man and she is not to usurp, or take the authority away from a man. So, how do we define a man? A boy physically becomes a man somewhere between eleven and thirteen. In the Hebrew tradition, a boy is declared to be a man at the age of thirteen. So, to be safe, a woman should not teach any boy over the age of ten.

Likewise, a woman should not lead a choir where there are choir members who are young men (see above) and she certainly should not be preaching.
Too many of our churches, even our conservative churches, are losing sight of the fundamentals. This may not be one of the foundational doctrines of the faith, but it is important. This is a “thus saith the Lord” precept that a church simply cannot ignore and expect to be blessed. God does not want women leading or teaching men.
For a church to allow such a thing to go on is a crying shame. It marks this church as far from old-fashioned and Bible-believing. In fact, I would go so far as to propose that this may be blasphemous. Consider this passage:

Tit 2:3-5 The aged women likewise, that they be in behaviour as becometh holiness, not false accusers, not given to much wine, teachers of good things; (4) That they may teach the young women to be sober, to love their husbands, to love their children, (5) To be discreet, chaste, keepers at home, good, obedient to their own husbands, that the word of God be not blasphemed.

It is impossible for a woman who is standing in front of a choir, a class or a congregation to be discreet! The passage above is telling the older women to teach the younger women to be all these things so that the Word of God will not be blasphemed. Is God saying that a women who is not discreet is blasphemous? God certainly puts a strong emphasis on the confusing of the genders. This is definitely a woman doing what God intended a man to do.
