Congratulations to the New York Senate for taking a step into the modern world — and especially to the Republicans who didn’t cave in to pressure from the reactionary religious lobby, and instead did the right thing: New York Allows Same-Sex Marriage, Becoming Largest State to Pass Law.

The marriage bill, whose fate was uncertain until moments before the vote, was approved 33 to 29 in a packed but hushed Senate chamber. Four members of the Republican majority joined all but one Democrat in the Senate in supporting the measure after an intense and emotional campaign aimed at the handful of lawmakers wrestling with a decision that divided their friends, their constituents and sometimes their own homes.

With his position still undeclared, Senator Mark J. Grisanti, a Republican from Buffalo who had sought office promising to oppose same-sex marriage, told his colleagues he had agonized for months before concluding he had been wrong.

“I apologize for those who feel offended,” Mr. Grisanti said, adding, “I cannot deny a person, a human being, a taxpayer, a worker, the people of my district and across this state, the State of New York, and those people who make this the great state that it is the same rights that I have with my wife.”
