Why the Church can support “breadwinning” wives too
Apparently, churches that advocate traditional family structures (and yes, they are traditional, exceptions not withstanding; I note that not one of her cited Biblical examples contra is reported as having young children) are "shutting the door to the kingdom." Somehow. Never heard of it happening, but I guess it probably happens somewhere. I doubt it's a significant temptation to those of her readership, however.
Titus 2:5 "keepers at home" has to mean something. Given Prov.31, we'd be off base to say it means wives never work outside the home. But the idea that there is a "homemaker" (oikourgos) is not merely tradition. Tradition informs us as to what the role looks like, how it works in a well ordered home. But the core idea is a biblical one. See also 1 Tim. 5:14. Though that passage speaks specifically of young widows, it arguable directs them to behave like married women with respect to keeping a home.
