What a series of days in American life, full of savage mayhem, uncommon forgiveness, resistance to forgiveness, furious debate, mourning, and, finally, justice and grace. As President Obama led thousands of mourners in Charleston, South Carolina, in “Amazing Grace,” I thought about late 2013 and early 2014. Obama’s Presidency was surely dwindling, if not finished. His mood was sombre, philosophical—which is good if you are a philosopher; if not, not.

Obama described himself to me then in terms of his limits—as “a relay swimmer in a river full of rapids, and that river is history.” More than a few columnists believed that Obama was now resigned to small victories, at best. But pause to think of what has happened, the scale of recent events.

On Thursday, the Supreme Court (despite an apocalyptic dissent about “pure applesauce” and “interpretive jiggery-pokery” by Justice Scalia) put an end to years of court cases and congressional attacks against the Affordable Care Act, which means that millions of Americans will no longer live in a state of perpetual anxiety about health costs.

On Friday, the Supreme Court (despite a curiously ill-informed dissent about Kalahari, Aztec, and Han mating rites by Chief Justice Roberts) legalized same-sex marriage nationally—a colossal (and joyous) landmark moment in the liberation of gay men and lesbians.
