Perhaps the best proof of the correctness of the scientific or naturalistic explanation of the career of man and of the incorrectness of the traditional or supernaturalistic one is afforded by the history of morals, the soul of both religion and politics, without which neither could have any existence.
Before the discovery of the art of agriculture, man was dependent for his food upon fruits and nuts, game and fish. When these sources of sustenance failed, the tribes living in the same neighborhood fought with each other in order that the victorious might eat the vanquished.
During this period cannibalism was morally right, and it probably extended through at least two hundred thousand years, even into the Old Testament times. So righteous and holy was it that, in the course of time, the victims were recognized as saviour gods and the drinking of their blood and eating of their flesh constituted a Lord's Supper in which the god was eaten.
Cannibalism is the basis of our sacrament of the holy communion of bread and wine. As a connecting link between these extremes there was the form of communion which consisted in the eating of animal sacrifices.
By a sacrament with such an origin, you and I render our highest act of worship, though yours is still directed towards one among the supernaturalistic divinities and mine is now directed towards humanity. You say of a divinity: Thou, Lord, hast made me after thine own image and my heart cannot be at rest until I find rest in thee. I say of humanity: Thou, Lord, hast made me after thine own image and my heart cannot be at rest until it find rest in thee.
Within the social realm humanity is my new divinity, and your divinity (my old one) is a symbol of it, or else, so I think, he is at best a fiction and at worst a superstition.
You will be surprised, and I do not expect you to understand me, when I tell you that by translating the services and hymns from the language of my old literalism into that of my new symbolism, I am getting as much good out of them as ever and indeed more. I love the services, especially that great one, the Holy Communion, and the hymns, especially those great ones, Guide Me O Thou Great Jehovah; Lead, Kindly Light; Abide With Me; and Jesus, Lover of My Soul.
My experience has convinced me that the sentimental and poetical elements in religion, to which I attach as much importance as ever, are as readily excited and securely sustained by fixing thought and sympathy upon the martyred human savior, the working class, as upon a crucified divine saviour, who after all, as the suffering son of God, is but a symbol of the suffering sons and daughters of man, the workers, from whom all good things come.
If grace at dinner means anything, it is addressed to a god who is the symbol of the many workers who did the innumerable things necessary to the producing and serving of it, without whom there would be nothing of all the good things on the table.
In the representation about my pleasure in the services of the church and their value to me, and in many representations scattered throughout this letter, I have in mind the question of an unanswered letter of yours, bearing date, February 25th, 1919, the one in which you ask, in effect, by what right a man can remain in an institution after he has, as I have, abandoned its chief doctrines and aims as they are authoritatively interpreted.
