"In our marriage debate, we aren’t dealing with a policy question. We’re dealing with a definition of the subject of our policies.
What’s at issue isn’t marriage and family law, or what sorts of arrangements we make concerning marriage and family. What’s at issue is the meaning of marriage itself, and consequently the meaning of family.
Marriage and family law have at their core, throughout history, a basic understanding of a universal fact: the sexual acts of man with woman result in children. For the sake of their offspring, they vow to each other and to the community to be sexually exclusive and remain together, blending their bodies, their goods, and their lives. Society supports them in their task. This is marriage."
