Letter from Thomas Jefferson to John Adams

Below is a letter written by Thomas Jefferson to John Adams toward the end of their lives (remarkably they died on the same day-Independence Day July 4, 1826-within five hours of each other). In the letter, Jefferson reveals his religious sentiments, pulling no punches about Calvinism and the doctrine of the trinity (he calls it “tritheism”). In the course of the letter, he also endorses the teleological argument, or argument from design, making an eloquent presentation of the argument. What strikes me most is the vehemence of Jefferson’s denunciation of Calvinism. A mere mention of John Calvin’s name by Adams (in his previous letter to Jefferson), and not even in a theological context,  sets Jefferson off.

To John Adams

Monticello, April 11, 1823

DEAR SIR, — The wishes expressed, in your last favor, that I may continue in life and health until I become a Calvinist, at least in his exclamation of “mon Dieu! jusque à quand!” [My God! Until when!] would make me immoral. I can never join Calvin in addressing his god. He was indeed an Atheist, which I can never be; or rather his religion was Daemonism. If ever man worshipped a false god, he did. The being described in his five points is not the God whom you and I acknowledge and adore, the Creator and benevolent governor of the world; but a daemon of malignant spirit. It would be more pardonable to believe in no god at all, than to blaspheme him by the atrocious attributes of Calvin.

Indeed I think that every Christian sect gives a great handle to Atheism by their general dogma that, without a revelation, there would not be sufficient proof of the being of a god. Now one sixth of mankind only are supposed to be Christians: the other five sixths then, who do not believe in the Jewish and Christian revelation, are without a knowledge of the existence of a god! This gives completely a gain de cause [proof] to the disciples of Ocellus, Timaeus, Spinosa, Diderot and D’Holbach.

The argument which they rest on as triumphant and unanswerable is that, in every hypothesis of cosmogony you must admit an eternal pre-existence of something; and according to the rule of sound philosophy, you are never to employ two principles to solve a difficulty when one will suffice. They say then that it is more simple to believe at once in the eternal pre-existence of the world, as it is now going on, and may for ever go on by the principle of reproduction which we see and witness, than to believe in the eternal pre-existence of an ulterior cause, or Creator of the world, a being whom we see not, and know not, of whose form substance and mode or place of existence, or of action no sense informs us, no power of the mind enables us to delineate or comprehend.

On the contrary I hold (without appeal to revelation) that when we take a view of the universe, in its parts general or particular, it is impossible for the human mind not to perceive and feel a conviction of design, consummate skill, and indefinite power in every atom of its composition. The movements of the heavenly bodies, so exactly held in their course by the balance of centrifugal and centripetal forces, the structure of our earth itself, with its distribution of lands, waters and atmosphere, animal and vegetable bodies, examined in all their minutest particles, insects mere atoms of life, yet as perfectly organised as man or mammoth, the mineral substances, their generation and uses, it is impossible, I say, for the human mind not to believe that there is, in all this, design, cause and effect, up to an ultimate cause, a fabricator of all things from matter and motion, their preserver and regulator while permitted to exist in their present forms, and their regenerator into new and other forms.

We see, too, evident proofs of the necessity of a superintending power to maintain the universe in its course and order. Stars, well known, have disappeared, new ones have come into view, comets, in their incalculable courses, may run foul of suns and planets and require renovation under other laws; certain races of animals are become extinct; and, were there no restoring power, all existences might extinguish successively, one by one, until all should be reduced to a shapeless chaos.

So irresistible are these evidences of an intelligent and powerful Agent that, of the infinite numbers of men who have existed thro’ all time, they have believed, in the proportion of a million at least to unit, in the hypothesis of an eternal pre-existence of a creator, rather than in that of a self-existent universe. Surely this unanimous sentiment renders this more probable than that of the few in the other hypothesis. Some early Christians indeed have believed in the coeternal pre-existence of both the Creator and the world, without changing their relation of cause and effect. That this was the opinion of St. Thomas, we are informed by Cardinal Toleto, in these words “Deus ab aeterno fuit jam omnipotens, sicut cum produxit mundum. Ab aeterno potuit producere mundum. — Si sol ab aeterno esset, lumen ab aeterno esset; et si pes, similiter vestigium. At lumen et vestigium effectus sunt efficientis solis et pedis; potuit ergo cum causâ aeterna effectus coaeterna esse. Cujus sententiae est S. Thomas Theologorum primus Cardinal Toleta.” [God has been omnipotent forever, just as when he made the world. He has had the power to make the world forever. If the sun were in existence forever, light would have been in existence forever; and if a foot then likewise a footprint. But light and footprint are the effects of an efficient sun and foot; therefore the effect has had the power to be co-eternal with the eternal cause. Of this opinion is St. Thomas, the first of the theologians.]

Of the nature of this being we know nothing. Jesus tells us that `God is a spirit’ (πνευμα ο θεος) but without defining what a spirit is (John 4.24). Down to the third century we know that it was still deemed material; but of a lighter subtler matter than our gross bodies. So says Origen. “Deus igitur, cui anima similis est, juxta Originem, reapte corporalis est; sed graviorum tantum ratione corporum incorporeus.” [God, therefore, to whom the soul is similar, in consequences of its origin, is in reality corporeal; but He is incorporeal in comparison with so much heavier bodies.] These are the words of Huet in his commentary on Origen. Origen himself says “Appelatio (asomaton) apud nostros scriptores est inusitata et incognita.” [The word, ασωματον, among our writers, is not known or used.] So also Tertullian: Quis autem negabit Deum esse corpus, etsi deus spiritus? Spiritus etiam corporis sui generis, in sua effigie.” [Yet who will deny that God is body, although God is spirit? Indeed He is spirit of His own type of body, in His own image.] These two fathers were of the third century.

Calvin’s character of this supreme being seems chiefly copied from that of the Jews. But the reformation of these blasphemous attributes, and substitution of those more worthy, pure and sublime, seems to have been the chief object of Jesus in his discourses to the Jews; and his doctrine of the cosmogony of the world is very clearly laid down in the three first verses of the first chapter of John, in these words, εν αρχη ην ο λογος και ο λογος ην προς τον θεον και θεος ην ο λογος ουτος ην εν αρχη προς τον θεον παντα δι αυτου εγενετο και χωρις αυτου εγενετο ουδε εν ο γεγονεν, which truly translated means, “In the beginning God existed, and reason (or mind) was with God, and that mind was God. This was in the beginning with God. All things were created by it, and without it was made not one thing which was made.”

Yet this text, so plainly declaring the doctrine of Jesus that the world was created by the supreme, intelligent being, has been perverted by modern Christians to build up a second person of their tritheism by a mistranslation of the word (λογος). One of it’s legitimate meanings indeed is “a word.” But, in that sense, it makes an unmeaning jargon; while the other meaning “reason,” equally legitimate, explains rationally the eternal preexistence of God and his creation of the world. Knowing how incomprehensible it was that “a word,” the mere action or articulation of the voice and organs of speech could create a world, they undertake to make of this articulation a second preexisting being, and ascribe to him, and not to God, the creation of the universe.

The Atheist here plumes himself on the uselessness of such a God, and the simpler hypothesis of a self-existent universe. The truth is that the greatest enemies to the doctrines of Jesus are those calling themselves the expositors of them, who have perverted them for the structure of a system of fancy absolutely incomprehensible, and without any foundation in his genuine words. And the day will come when the mystical generation of Jesus, by the supreme being as his father in the womb of a virgin will be classed with the fable of the generation of Minerva in the brain of Jupiter. But we may hope that the dawn of reason and freedom of thought in these United States will do away with all this artificial scaffolding, and restore to us the primitive and genuine doctrines of this the most venerated reformer of human errors.

So much for your quotation of Calvin’s “mon Dieu! jusqu’a quand!” in which, when addressed to the God of Jesus, and our God, I join you cordially, and await his time and will with more readiness than reluctance. May we meet there again, in Congress, with our ancient colleagues, and receive with them the seal of approbation “Well done, good and faithful servants.”
