An ethic is the inner structure of a polity.
Sacramental Theology and Covenant Theology are largely resistant to the acids of egalitarian ideology.
These theologies draw upon the polity of the traditional household for insight into the polity of salvation. For Sacramental Theology and Covenant Theology meaning is embedded in the nature of things and traditional household polity reflects heavenly realities.
But for the egalitarians nature is as meaningless as Silly Putty and just as subject to the impress of the human will.
Egalitarians, from Rousseau to Marx, have looked to the state to break down natural structures and to liberate, which is to say isolate, people. Ostensibly liberation allows people to define the meaning of their own lives. But what it actually does is strip them bare and leave them exposed to the zeitgeist and machinations of state power.
