I was reading through Deuteronomy (wow, got it right from memory

) the other day and I was struck by how much of the "law" was just plain old common sense. Just one example. In chapter 23, verses 9 through 13, God discusses how to keep war camps "clean". "When you are encamped against your enemies, keep away from everything impure. ... Designate a place outside the camp where you can go to relieve yourself. As part of your equipment have something to dig with, and when you relieve yourself, dig a hole and cover up your excrement." What the Israelites regarded as "law", we see as simple basic hygiene.
I think that most of the biblical attitude toward women can be summed up by the following. "A woman's place is in the home." Chauvinistic? Radical? Unfair? Not if you believe many modern day observers of society. Evidence is mounting that proves that
the decline of America can be traced directly to the breakdown of the traditional family. Thank you feminist movement. (I don't dignify it with capitalization.)
Therefore, based on Biblical reasoning, women couldn't be officials in the church because they were supposed to be at home, minding the hearth fires. This role was not demeaned in any way. Read Proverbs' description of the "noble wife". However, it was incompatible with any other tasks which might take precedence over her primary wifely duties.
So, I guess that the most reasonable answer to the question "Can women be pastors?" would be "only if they are not married, nor have any other familial responsibilities".
