The Christian tradition of marriage between a man and a woman can be understood as expressing social justice in the civil realm, in light of definitions of identity in terms of relationship, and of society as a household by the Russian Orthodox philosophers Pavel Florensky and Sergius Bulgakov, respectively. Both models support traditional marriage as an embodied symbol of relationship among human beings, nature, and God as expressed in Christian culture for centuries in lived intergenerational experience. Such intergenerational perspective on faith and social justice provides an argument for traditional marriage as a public institution based on an ethos of socioeconomic as well as spiritual sustainability.
