Tom, this is in response to your last post.
You wrote: For example, we both agree that 1st Tim. 2:12ff forbids women serving in the pastoral office. But if I understand you correctly, you also insist that 1st Tim. 2:12 is not limited to the Divine Service nor is it limited to forbidding women serving in the pastoral office but also forbidding a woman from teaching Scripture to ANY man in ANY situation. Correct?
I reply: No, Tom, that’s incorrect as I have said repeatedly above, there is nothing wrong with a woman teaching a man privately.
You wrote: If so, then why do you believe it was permissible for Priscilla to teach Apollos? If I understand you correctly, you would then qualify 1st Tim. 2:12 by saying that it does NOT forbid a woman teaching Scripture to men in a PRIVATE situation but it DOES forbid a woman teaching Scripture to a man in a PUBLIC situation. Correct?
I reply: No, I would not qualify 1 Timothy 2:12. It forbids women from publicly teaching God’s Word to men. It not does address what Pricilla did as recorded in Acts 18.
You wrote: If so, then you insist the what Priscilla did with Apollos was a PRIVATE situation but a woman doing the same thing in a seminary classroom would be a PUBLIC situation. Am I understanding you correctly?
I reply: Yes.
You wrote: If so, then what is it about a seminary classroom filled with non-ordained men that is different from what Priscilla did with Apollos or a deaconess teaching Scripture to men at her home? Please explain the basis of your distinction to me.
I reply: First of all, I would not liken what Pricilla did to a deaconess teaching Scripture to men in her home. A deaconess should not be teaching theology to men in her home. I have already explained to you what the theological professor in the seminary classroom is doing. He is exercising the authority of his office as a teacher of God’s Word. He is doing so publicly, that is, according to his office as a public teacher. No woman may hold this office, according to God’s Word.
You wrote: Honestly, I don't see a difference between what Priscilla did with Apollos and what a woman with a PhD in theology could do with non-ordained men in a classromm setting. If you see a difference, please explain it to me.
I reply: I find it hard to believe that you cannot see the difference. Pricilla, with her husband, explained things to Apollos that needed explaining. It was an ad hoc meeting. They took him aside. Neither Pricilla nor Aquilla wanted to embarrass Apollos. It would have been unthinkable for Pricilla to have presumed to teach Apollos publicly in the synagogue. Doing so is comparable to a woman teaching theology to men in a seminary classroom. It is unseemly. It vitiates her womanly nature. I should also point out that a woman with a PhD in theology has been trained to do what God forbids her to do.
You wrote: Now, with all that said, I agree with you that the ideal situation is that pastors with higher degrees teach our men at the seminary. This is why I have always argued that it would be best (but not required by God's Word) that professors at our seminaries have at least some experience serving as a pastor in a congregation because there's more to seminary education then simply studying Scriputure in an academic settting but we should also give our seminary students the chance to learn from pastors who have used their knowledge of Scripture in the actual pastoral care of God's people. I assume you would agree with me on this.
I reply: I agree with you.
You wrote: Nevertheless, I don't think 1st Tim. 2:12 forbids the occasional situation where a lay woman with a PhD in theology would share her insights from Scripture with non-ordained men in a classroom setting because I see this as being similar to what Priscilla did with Apollos and not the same as what a pastor does in the Divine Service. If you think a seminary classroom is NOT the same as what Priscilla did with Apolls but that it IS the same as what a pastor does in the Divine Service, please explain how. I want to understand your view. Thanks.
I reply: I have already explained this to you. Please reread my posts from yesterday. I pointed out that the Word of God is the Word of God whether preached from the pulpit or taught in the seminary classroom. There is no essential difference between the two. When the Word of God is placed within a liturgical form it is no different than that same Word of God taught in a different forum. That you cannot see this frankly baffles me.
Now, go to bed and get a good night's sleep! 
Rolf, thanks for your response. However, you assume that your position is clear when I think it remains a bit "fuzzy."
First, I now understand better your view of 1st Tim. 2:12. You believe it forbids a woman from all PUBLIC teaching of theology - and that this PUBLIC teaching is not limited (according to you) to the liturgical Divine Service. Correct?
Second, you assert that it should be obvious to me that what Priscilla did was PRIVATE versus a seminary classroom which is PUBLIC. You based this on the fact that Priscilla did not teach in the synagogue but taught Apollos privately in her home. I have two problems with this.
1) You seem to equate a synagogue Service of gathered Christians with a seminary classroom. I don't think such a comparison is all that obvious.
2) Even though you're OK with what Priscilla did with Apollos in her home you said you'd have a problem with a deaconess doing the same thing with non-ordained men in her home. But why? You say I should know the difference but you fail to show what that difference is. You just ASSERT there's a difference without explaining WHY those settings are different. That's what I'm asking you to do (and what you have NOT done yet!): Please do not merely ASSERT that what Priscilla did in her home with Apollos is different than a deaconess sharing her insights from Scripture with men in her home, but please explain WHY and HOW they are different. You have not done that yet, in my opinion.
Finally, you say that a woman who has a PhD in theology has been trained to do what a woman should not do. Why is that? I know women with PhDs in theology who believe Scripture forbids them to serve as ordained pastors - and yet they share their insights about Scripture as lay women with other lay people (NOT in the Divine Service!) just as Priscilla did with Apollos in her home. Now, I know what you will say next:
"Tom, isn't it obvious to you that what Priscilla did with Apollos in her home is far different than a deaconess teaching men about God's Word in her home or a seminary classroom?!" No, it ISN'T obvious to me nor to many others and you have not given much of a reason WHY there's a difference other than simply asserting that there is - and why should we believe your MERE assertions? You've got to do better than that.
