Andreas Kostenberger has two helpful--and to my mind persuasive--blog entries on the debates issues of whether women can be deacons (yes) and whether its a requirement for an elder to have born-again children (no).
For a more detailed exegetical look at these issues--along with the question of what the phrase mias gynaikas andra in 1 Timothy 3:2 and 120--see Kostnberger's “The New Testament Pattern of Church Government,” Midwestern Journal of Theology (forthcoming in Spring 2006).
