Our nation was founded on a bedrock principle that we are all created equal. The project of each generation is to bridge the meaning of those founding words with the realities of changing times -- a never-ending quest to ensure those words ring true for every single American.

Progress on this journey often comes in small increments. Sometimes two steps forward, one step back, compelled by the persistent effort of dedicated citizens. And then sometimes there are days like this, when that slow, steady effort is rewarded with justice that arrives like a thunderbolt.

This decision will end the patchwork system we currently have. It will end the uncertainty hundreds of thousands of same-sex couples face from not knowing whether their marriage, legitimate in the eyes of one state, will remain if they decide to move or even visit another.

This ruling will strengthen all of our communities by offering to all loving same-sex couples the dignity of marriage across this great land.

We are people who believe every child is entitled to life and liberty and the pursuit of happiness. There is so much more work to be done to extend the full promise of America to every American. But today, we can say in no uncertain terms that we’ve made our union a little more perfect. (...)

The right to marry whoever one wishes is an elementary human right compared to which "the right to attend an integrated school, the right to sit where one pleases on a bus, the right to go into any hotel or recreation area or place of amusement, regardless of one’s skin or color or race" are minor indeed. Even political rights, like the right to vote, and nearly all other rights enumerated in the Constitution, are secondary to the inalienable human rights to "life, liberty and the pursuit of happiness" proclaimed in the Declaration of Independence; and to this category the right to home and marriage unquestionably belongs.

And what public institution is more central -- more definitive -- of that connection than marriage? The denial of marriage to gay people is therefore not a minor issue. It is the entire issue. It is the most profound statement our society can make that homosexual love is simply not as good as heterosexual love; that gay lives and commitments and hopes are simply worth less. It cuts gay people off not merely from civic respect, but from the rituals and history of their own families and friends. It erases them not merely as citizens, but as human beings. (...)

I think of the gay kids in the future who, when they figure out they are different, will never know the deep psychic wound my generation -- and every one before mine -- lived through: the pain of knowing they could never be fully part of their own family, never be fully a citizen of their own country. I think, more acutely, of the decades and centuries of human shame and darkness and waste and terror that defined gay people’s lives for so long. And I think of all those who supported this movement who never lived to see this day, who died in the ashes from which this phoenix of a movement emerged. This momentous achievement is their victory too -- for marriage, as Kennedy argued, endures past death. (...)

No union is more profound than marriage, for it embodies the highest ideals of love, fidelity, devotion, sacrifice, and family. In forming a marital union, two people become something greater than once they were. As some of the petitioners in these cases demonstrate, marriage embodies a love that may endure even past death. It would misunderstand these men and women to say they disrespect the idea of marriage. Their plea is that they do respect it, respect it so deeply that they seek to find its fulfillment for themselves. Their hope is not to be condemned to live in loneliness, excluded from one of civilization’s oldest institutions. They ask for equal dignity in the eyes of the law. The Constitution grants them that right.

The judgment of the Court of Appeals for the Sixth Circuit is reversed.

It is so ordered.
