From President Obama's opening remarks: "Each time we gather to inaugurate a President we bear witness to the enduring strength of our Constitution. We affirm the promise of our democracy. We recall that what binds this nation together is not the colors of our skin or the tenets of our faith or the origins of our names. What makes us exceptional -- what makes us American -- is our allegiance to an idea articulated in a declaration made more than two centuries ago: 'We hold these truths to be self-evident, that all men are created equal; that they are endowed by their Creator with certain unalienable rights; that among these are life, liberty, and the pursuit of happiness.' Today we continue a never-ending journey to bridge the meaning of those words with the realities of our time. For history tells us that while these truths may be self-evident, they've never been self-executing; that while freedom is a gift from God, it must be secured by His people here on Earth. (Applause.) The patriots of 1776 did not fight to replace the tyranny of a king with the privileges of a few or the rule of a mob. They gave to us a republic, a government of, and by, and for the people, entrusting each generation to keep safe our founding creed."
