Anyway, Logan tackles the question of the day from a slightly different Francophone angle: not 'equality' but 'liberty'. I think he puts my concerns in a helpful way: marriage is marriage. Some parts of it can be altered, and need regulation (registration, dealing with dissolution), and the State has an appropriate role in the rules regarding such. But the State defining the essence of marriage (strictly speaking, 'redefining') is new territory in the history of humanity.
"Well, some French friends put the notion of equality under examination. They say same-sex marriage "n'est pas l'egalite, il s'agit de la liberte". It's not about equality; it's about liberty.
Governments who choose to redefine marriage seldom understand what they're doing. "Il a toute la laideur de la fierte." It has all the ugliness of pride.
The issue is not about equality or the success of any one couple's marriage. The issue is about the connection between the state and marriage in civil society. Who decides what marriage is and what it's for?
Marriage is neither essentially religious nor a product of tradition. It is not the child of the state.
Neither is marriage what Lynne Featherstone, the British Equalities Minister, claims. "Marriage is a right of passage for couples who want to show they are in a committed relationship, for people who want to show they have found love and wish to remain together until death do them part." Her historical vision is limited; her logic is deficient and her fusion of the Anglican Prayer Book with modern idiom disingenuous.
Marriage is the consequence of who we are.
We do not make it; it makes us. We are male and female.
In the simple and hopeful business of being alive, we have children in a union of accepted responsibility, love and thankfulness. It is the cementing of two opposite halves of the human being through which new life may be created. That some couples decide not to get married does not change the biology. That some cannot have children or decide not to is beside the point.
To say that you do not believe in marriage or that it is superfluous does not change the truth of its historical and cultural value.
The dogma that asserts marriage is primarily about love and commitment is frequently accompanied by the counter-claim: "I'm in love and committed so why do I need to bother about marriage?Marriage is what I say it is and anyway I don't need it." That blurring of the status and meaning of marriage is contributing to a range of unfortunate consequences yet to be grasped."
The whole argument is here.
