I can promise you that you'll be hearing the following words in thousands of same-sex marriage ceremonies to come:
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.
Those words were written by Justice Anthony Kennedy in his majority ruling affirming the right of same-sex couples to legally marry in the United States. For years, we've been seeing an excerpt from the Goodridge ruling (in Massachusetts) as a big part of same-sex marriage ceremonies, but I believe that ruling, written by Justice Margaret Marshall, will be usurped by this from Justice Kennedy.
Same-sex couples commonly make some reference to marriage equality (or previously, the lack thereof), in their ceremonies. It puts their marriage in context and lets the guests know that they do not take their rights to marry for granted. Watch out for this for years to come.
