The Court struck down the part of the federal marriage law defining the institution of marriage as a union between one man and one woman for the purpose of interpreting and administering all federal laws and programs. Without Section 3, the federal government will not be able to define marriage for its own federal policies and federal laws; it must accept whatever states decide about same-sex marriage.

Your marriage and mine are the single greatest influences that can be presented to the world on the significance of marital oneness.
