To legalize marriage between two people of the same sex would enshrine in the law the principle that mothers and fathers are interchangeable or irrelevant, and that marriage is essentially an institution about adults, not children; marriage would mean nothing more than giving adults recognition and benefits in their most significant relationship.
How can we do this to our children?
Why has virtually every known civilization across time and history recognized the need to bring together men and women to make and raise the next generation together? Clearly something important is at stake, or human beings of such different cultures, histories and religions would not come up with the basic idea of marriage as a male-female union over and over again.
When we as a culture abandon that idea and ideal, children suffer, communities suffer, women suffer, and men are dehumanized by being told they aren’t important to the project of family life.
Our bodies have meaning. The conjugal union of a man and a woman is not a factory to produce babies; marriage seeks to create a total community of love, a “one flesh” union of mind, heart and body that includes a willingness to care for any children their bodily union makes together. Two men and two women can certainly have a close loving committed emotional relationship, but they can never ever join as one flesh in the unique way a husband and wife do.
Treating same-sex relationships as marriage is the final severing by government of the natural link between marriage and the great task of bringing together male and female to make and raise the next generation together in love.
