OK, I’ll attempt a brief reply to James Y. as well:
The only explicit passage about ‘teaching’ or ‘having authority’ is 1 Tim 2:12 (quoting from v11)
11 A woman should learn in quietness and full submission. 12 I do not permit a woman to teach or to have authority over a man; she must be silent. 13 For Adam was formed first, then Eve.... (NIV)
The debates over the translation are voluminous, but I haven’t yet been convinced of the alternatives. (Not to mention the arguments about pseudonymous authorship of the pastorals - of which I have not been convinced by the ‘liberal consensus’.)
You will note that the argument about Eve is a supporting argument to the command in verse 12, and is not an argument about the contemporary situation, but an argument from creation order. I don’t think you should be writing it off as quickly as you seem to do - but perhaps I misunderstand?
Paul says: “I do not permit ...” - could he just be giving a personal preference? No, the first person singular is also used in 2:1, 8 & 9 - all ‘timeless commands’ as far as most people are concerned. Note also Paul’s mention of his apostolic authority in 2:7, which reminds us that Paul’s prohibition carries significant weight!
Of course this may be the only explicit verse about teaching, but it goes in the same direction as passages on church order (1 Cor 11:3-14; 14:33-34); on the appointment of leaders (1 Tim 3:2ff; Titus 1:5ff); and commands to wives about submission to husands (Ephesians 5:22-32; Colossians 3:18 and 1 Peter 3:1 ff).
As for the significance of the contemporary situation in Ephesus ... certainly there were false teachers (1 Tim 1:3) The only ones named as such are Hymenaeus and Philetus (male names) “who have wandered away from the truth. They say that the resurrection has already taken place, and they destroy the faith of some” (2 Tim 2:18). Some commentators would argue that since the dominant feature of Ephesus was the great temple of Artemis (Diana) that the city must have had a significant female leadership and this was causing problems in the church as women tried to ‘domineer’ over men. The only problem with this argument is that the feminine domination of Ephesus is yet to be proven. An article by Steven M. Baugh has done a thorough study of the historical evidence and argues that - contra the assertions by many previous commentators - the temple of Artemis was run by several groups of men who were also leaders of the city. The implication is that the argument about a ‘local problem’ has no foundation. Even if it did, there is no indication in the text that this should be a temporary restriction - in fact the appeal to creation order pushes us the other way.
Baugh’s article is found in Women in the Church: A Fresh Analysis of 1 Timothy 2:9-15 edited by Kostenberger, Schreiner and Baldwin (Grand Rapids: Baker, 1995). This whole book provides a careful critique of many ‘egalitarian’ arguments and an overall argument for the ‘complementarian’ or ‘traditional’ understanding of 1 Timothy 2.
