"Let us wear equality; but let us undress every night."
C. S. Lewis, "Equality," in Present concerns: a compelling collection of timely, journalistic essays (San Diego: A Harvest Book, Harcourt, Inc., 1986), 19-20, underscoring mine.
under the necessary outer covering of legal equality, the whole hierarchical dance and harmony of our deep and joyously accepted spiritual inequalities should be alive. It is there, of course, in our life as Christians: there, as laymen, we can obey — all the more because the priest has no authority over us on the political level. It is there in our relation to parents and teachers — all the more because it is now a willed and wholly spiritual reverence. It should be there also in marriage.
Something like complementarian "difference" might be preferable to "inequality", however, and there are other claims in this essay that I'm unsure of. But there's also a lot that's quite right about it.
