Before we talk about redefining it, let's talk about what marriage is and what it isn't. Marriage is an institution that predates our government, society and any religion. It legitimizes the only way to create, and the best way to raise, our next generation. Marriage originates from the unique relationship between a man and a woman, and their exclusive ability, grounded in nature, to conceive children and to nurture those children as a mother and a father. In short, marriage protects the source of life. Marriage is not simply something that validates the love that two people share for each other. It's much more than that.
