I originally received the impression from this quote that Osiek might be speaking approvingly of "love patriarchy." However, the larger context suggests she is not. I think that readers here might be interested in knowing what the next words were in Osiek's original discussion. This is the quote in context,
[Christianity] was part of a wider movement that was moving with glacial speed toward a more humane patriarchy, in Christian terms, perhaps, something like Troeltsch’s “love patriarchy.”
Did Christianity move away from patriarchy? I think it was part of a wider movement that was moving with glacial speed toward a more humane patriarchy, in Christian terms, perhaps, something like Troeltsch's "love patriarchy." Patriarchy is no less patriarchy if enacted with love, it seems to me.I get the impression that Osiek is not condoning patriarchy in her discussion of it. She is suggesting that if the biblical authors were here today they would support relationships of equal regard.
Ultimately though, our biblical hermeneutic here is not historical but theological. We want to know what it all means for us today. Where I come from, we do not have to prove that what we are doing is the same as what they did, only that it is in some kind of organic continuity. To this, I can readily assent: that we are doing today what they would do if they were here. Equal regard, let's do it.
