‘Patterns of human action embody particular conceptions, not only of what it is, but of what it might be, to be human: they simultaneously express both fact and possibility, actuality and hope. Patterns of human action – whether individual, domestic, social or political – thus symbolically express both what is and what might be meant by “humanity” … If human existence, as it is and as it might be made to be, is the contingent expression of the creative and transformative action of God, then patterns of human action are not merely symbolic but are, in principle, sacramental – expressive of the mystery of grace’. – Nicholas Lash, Theology on the Way to Emmaus (Eugene: Wipf & Stock, 2005), 5–6.
