Since we need new material I suggest the following:
Titus 2:3
The aged women likewise, that they be in behaviour as becometh holiness, not false accusers, not given to much wine, teachers of good things; (KJV)
Likewise, teach the older women to be reverent in the way they live, not to be slanderers or addicted to much wine, but to teach what is good. (NIV)
Paul is expecting them to teach. And really many in the body are going to teach.
Col 3:16
Let the word of Christ dwell in you richly,
teaching and admonishing one another in all wisdom, singing psalms and hymns and spiritual songs, with thankfulness in your hearts to God.
Now one may say that this means that they can only teach the younger women but it does not say that. If people will slow down and read it without preconceived interpretations they will notice that it is not restricting women to teach women only. That interpretation is inserted to fit an idea that was not in Paul's mind as far as I can tell.
1You, however, must teach what is appropriate to sound doctrine. 2Teach the older men to be temperate, worthy of respect, self-controlled, and sound in faith, in love and in endurance.
3Likewise, teach the older women to be reverent in the way they live, not to be slanderers or addicted to much wine, but to teach what is good. 4Then they can urge the younger women to love their husbands and children, 5to be self-controlled and pure, to be busy at home, to be kind, and to be subject to their husbands, so that no one will malign the word of God.
One thing I notice is the similarity between this and 1 Tim 2:12. It also is similar to 1 Pet 3. When you compare these you see they are all talking about the same thing an attitude of the women to their husbands and not a ban on teaching the bible in the church or leading a church if necessary in some situation that might arise and a woman elder be found to be the one most capable for the task.
A woman elder leading a church could model this behavior of being subject to her husband for the younger to follow at the same time while serving as an elder.
