As Calvin Coolidge put it, in a remarkable speech delivered on the 150th anniversary of the signing of the Declaration of Independence,
No one can examine this record and escape the conclusion that in the great outline of its principles the Declaration was the result of the religious teachings of the preceding period. The profound philosophy which Jonathan Edwards applied to theology, the popular preaching of George Whitefield, had aroused the thought and stirred the people of the Colonies in preparation for this great event. No doubt the speculations which had been going on in England, and especially on the Continent, lent their influence to the general sentiment of the times. Of course, the world is always influenced by all the experience and all the thought of the past. But when we come to a contemplation of the immediate conception of the principles of human relationship which went into the Declaration of Independence we are not required to extend our search beyond our own shores. They are found in the texts, the sermons, and the writings of the early colonial clergy who were earnestly undertaking to instruct their congregations in the great mystery of how to live. They preached equality because they believed in the fatherhood of God and the brotherhood of man. They justified freedom by the text that we are all created in the divine image, all partakers of the divine spirit. . . .
If this apprehension of the facts be correct, and the documentary evidence would appear to verify it, then certain conclusions are bound to follow. A spring will cease to flow if its source be dried up; a tree will wither if it roots be destroyed. In its main features the Declaration of Independence is a great spiritual document. It is a declaration not of material but of spiritual conceptions. Equality, liberty, popular sovereignty, the rights of man—these are not elements which we can see and touch. They are ideals. They have their source and their roots in the religious convictions. They belong to the unseen world. Unless the faith of the American people in these religious convictions is to endure, the principles of our Declaration will perish. We can not continue to enjoy the result if we neglect and abandon the cause.
Amen!
I think Coolidge should have actually read the sermons of Whitefield and Edwards before making the claims he did.
Perhaps some universalists or unitarians preached "the brotherhood of man" or participation in the divine nature, or such things, but the Great Awakening was Calvinist through and through, emphasizing the utter depravity of man, the Sovreign Grace of God, and the necessity of repentanct.
