It was the conclusion of President Obama's address on health care that truly moved me. I heard strong echoes of Catholic social justice teaching, in both the words of Sen. Ted Kennedy, and in Obama's own embrace of the philosophy of the "common good."

Obama quoted a letter written in May by Sen. Kennedy reminding him that health care "concerns more than material things." "What we face," he wrote, "is above all a moral issue; at stake are not just the details of policy, but fundamental principles of social justice and the character of our country."

"Social justice!" How long has it been since we've heard a president utter that phrase? Too long.

Obama continued on that theme as he laid out, almost professorially, a mini-history of the competing philosophies that have shaped our political history … rugged individualism and self-reliance with its skepticism of government vs. a concern for the other and a realization that justice and fair play demand a positive role for government. And then, he came down squarely in favor of the latter:

As I heard those words, I wondered if Obama's own experience as a community organizer, working with Catholic Charities on the south side of Chicago, had more influence on him than we knew.
