“This is the price and the promise of citizenship. This is the source of our confidence -- the knowledge that God calls on us to shape an uncertain destiny. This is the meaning of our liberty and our creed, why men and women and children of every race and every faith can join in celebration across this magnificent mall; and why a man whose father less than 60 years ago might not have been served in a local restaurant can now stand before you to take a most sacred oath.”
