Marriage is not defined; it is described. Marriage is not invented by man, rather it is rooted in nature and a fixed feature of the natural order. Marriage relationships produce the next generation. Families consisting of a father and a mother are building blocks of society. This description has dictated the structure of every civilization from the beginning of time.

Thus, changing language or laws doesn't change reality. Same-sex marriage never occurred until now because it was a contradiction in terms. Such unions would not be marriages even if declared so because nature decrees otherwise.

Marriage licenses don't create marriages, they simply "map over" the natural institution already there from the beginning. Governments don't create marriages, so they can't ultimately redefine them. Governments can only cause damage by interfering with marriage instead of cooperating with its natural purpose.
