“The idea of the American 'creedal nation,' which is supposed to unite us all in 'a common commitment to a set of ideas and ideals,' is abstract and inorganic. This creed comes from above, not from below. It's a state religion reflexively developed to bring about compliance.”

1954

Notes from Devotional Authors of the Middle Ages (1873-1874)
Context: These old Mystics whom we call superstitious were far before us in their ideas of God and of prayer (that is of our communion with God). "Prayer," says a mystic of the 16th century, "is to ask not what we wish of God, but what God wishes of us." "Master who hast made and formed the vessel of the body of Thy creature, and hast put within so great a treasure, the Soul, which bears the image of Thee": so begins a dying prayer of the 14th century. In it and in the other prayers of the Mystics there is scarcely a petition. There is never a word of the theory that God's dealings with us are to show His "power"; still less of the theory that "of His own good pleasure" He has " predestined" any souls to eternal damnation. There is little mention of heaven for self; of desire of happiness for self, none. It is singular how little mention there is either of "intercession " or of " Atonement by Another's merits." True it is that we can only create a heaven for ourselves and others "by the merits of Another," since it is only by working in accordance with God's Laws that we can do anything. But there is nothing at all in these prayers as if God's anger had to be bought off, as if He had to be bribed into giving us heaven by sufferings merely "to satisfy God's justice." In the dying prayers, there is nothing of the "egotism of death." It is the reformation of God's church—that is, God's children, for whom the self would give itself, that occupies the dying thoughts. There is not often a desire to be released from trouble and suffering. On the contrary, there is often a desire to suffer the greatest suffering, and to offer the greatest offering, with even greater pain, if so any work can be done. And still, this, and all, is ascribed to God's goodness. The offering is not to buy anything by suffering, but — If only the suppliant can do anything for God's children!
These suppliants did not live to see the " reformation" of God's children. No more will any who now offer these prayers. But at least we can all work towards such practical " reformation." The way to live with God is to live with Ideas — not merely to think about ideals, but to do and suffer for them. Those who have to work on men and women must above all things have their Spiritual Ideal, their purpose, ever present. The "mystical " state is the essence of common sense.

Nobel lecture (2001)

2013, Commencement Address at Ohio State University (May 2013)
Context: In the aftermath of darkest tragedy, we have seen the American spirit at its brightest. We’ve seen the petty divisions of color, class, and creed replaced by a united urge to help. We’ve seen courage and compassion, a sense of civic duty, and a recognition that we are not a collection of strangers; we are bound to one another by a set of ideals, and laws, and commitments, and a deep devotion to this country we love. 
That’s what citizenship is. It’s the idea at the heart of our founding – that as Americans, we are blessed with God-given and inalienable rights, but with those rights come responsibilities – to ourselves, to one another, and to future generations. 
But if we’re being honest, as you’ve studied and worked and served to become good citizens, the institutions that give structure to our society have, at times, betrayed your trust. In the run-up to the financial crisis, too many on Wall Street forgot that their obligations don’t end with their shareholders. In entertainment and in the media, ratings and shock value often trumped news and storytelling. And in Washington – well, this is a joyous occasion, so let me put this charitably: I think it’s fair to say our democracy isn’t working as well as we know it can. It could do better. And those of us fortunate enough to serve in these institutions owe it to you to do better, every single day.

"At Large", speech at the Peace Corps twenty-fifth anniversary memorial service (21 September 1986), published in Moyers on Democracy (2008), p. 26
Context: nowiki>[George Washington] in uniform patriotism can salute one flag only, embrace but the first circle of life — one's own land and tribe. In war that is necessary, in peace it is not enough. Events enlarged his embrace to a wholly new idea of nation — the United States of America. But less than a century later his descendant by marriage could not slip the more parochial tether. In the halls of the family home standing on the hill above us, General Robert E. Lee paced back and forth as he weighed the offer of Abraham Lincoln to take command of the Union Army on the eve of the Civil War. Lee turned the offer down and that evening took the train to Richmond. His country was still Virginia. We struggle today with the imperative of a new patriotism and citizenship. The Peace Corps has been showing us the way, and the volunteers and staff whom we honor this morning are the vanguard of that journey.

Mother India's Lighthouse: India's Spiritual Leaders (1971)
Context: No religion is absolutely perfect. Yet not only do we fight for religion, but also are we often willing to sacrifice our lives for it. And what we hopelessly fail to do is to live it. A true religion is that which has no caste, no creed, no colour. It is but an all-uniting and all-pervading embrace.
