Fly Caster,
"Keeper at home" is actually a textual variant. The two readings are:
οικουργους-working at home
οικουρους-keeper at home
They are very similar. Most text critics that I have talked to here at Trinity have noted a couple of things. First, the reading οικουργους [working at home] is the more primative and widest attested reading. It is in the original hand of Codex Siniaticus, Codex Alexandrinus, the original hand of Codex Bezae [a western manuscript] as well as later manuscripts such as 33 and 81. Also, the word οικουρους was far more common in the ancient world. We only know of one or two more occurances of οικουργους, while οικουρους is well attested. The tendency is to go from the least common to the more common. If οικουρους were original, there would be no reason to change it to the far less common οικουργους.
Also, I think the context of Titus 2 is important. Paul is speaking in an ethical context, not a context of gender roles. Women are also called to love their children [v.4]. Does that mean that it is okay for the husband to hate his children because it is the woman's gender role to love the children? Women are also called to be pure and kind [the two words surrounding "working at home" in verse 5]. Does that mean that husbands can be sinful, defiled, and mean because it is the woman's gender role to be pure and kind? No, Paul's context here is of an ethical nature, not of a nature of gender roles.
In other words, what if Paul were talking about women working at home, but at the same time, not excluding men from that task, in the same way he does not exclude them from purity and kindness? One can easily see how ethical issues such as slothfulness in the home on the part of both the husband and the wife can put stress on a marriage, and lead to major problems. One can also see how this could be the case in the context of the problem of women as gossips and busybodies, which is something Paul has to address elsewhere [1 Timothy 5:13]. Thus, Paul's concern would be for women to give appropriate help to their husband and children in the home so that their idleness is does not give an occasion for the word of God to be blasphemed.
I would even think most people who are homemakers would get upset if their husband always came home from work, propped up his feet, and did nothing the rest of the day!
Now, as far as Proverbs 31, I don't think the point of Proverbs 31 is to speak of a woman who actually exists. Not only are their connections to wisdom, but there also seems to be a connection to the sections dealing with the kind of woman a man is to be seeking. Thus, these are the kinds of traits that show that a woman is wise. Also, I don't think it will do to speak about a "carrier woman" or a "homemaker." Such is entirely anachronistic, and totally a product of the industrial revolution. Now, if you demand the family-centered agrarian society of the ANE, you also have to reckon with the fact that the family structure was different. Not only did one generation live in a home and work together, but there could be up to three generations living and working together. Worse than that, families in the ANE also included slaves and resident aliens [does that mean that you could invite someone to live with you, and look after your children while you go to work?]. Also, it would not usually be the husband who would have authority over the members of the family, but the oldest living patriarch. Thus, the husband and the wife may not have the authority in the home; it might end up being with the great-grandfather. Also, if you were a resident alien, the authority in your home might not even belong to someone in your own family!
Indeed, I think both the agrarianism of the southern confederacy [common in modern patriarchy] as well as the feminism of the 1970's are both inappropriate paradigms for understanding the context of the Bible. To read either of these ideas back into the text is totally anachronistic. Suffice it to say that the Bible allows for work and profit, but not at the expense of leaving everyone in your family with all the work at home, and certainly not at the expense of taking care of your children. The Bible makes very clear that *all* of these areas are important, and for any household to neglect any one of these is wrong.
God Bless,
