"After he [Servetus] had been recognized, I thought he should be detained. My friend Nicolas summoned him on a capital charge, offering himself as a security according to the lex talionis. On the following day he adduced against him forty written charges. He at first sought to evade them. Accordingly we were summoned. He impudently reviled me, just as if he regarded me as obnoxious to him. I answered him as he deserved ... of the man's effrontery I will say nothing; but such was his madness that he did not hesitate to say that devils possessed divinity; yea, that many gods were in individual devils, inasmuch as a deity had been substantially communicated to those equally with wood and stone. I hope that sentence of death will at least be passed on him; but I desired that the severity of the punishment be mitigated."
"Is it faith to understand nothing, and merely submit your convictions implicitly to the Church?"
"God preordained, for his own glory and the display of His attributes of mercy and justice, a part of the human race, without any merit of their own, to eternal salvation, and another part, in just punishment of their sin, to eternal damnation."
"True believing Christians are sheep among wolves. ... They employ neither worldly sword nor war, since with them killing is absolutely renounced."
"Reason is the Devil's harlot, who can do nought but slander and harm whatever God says and does."
"What harm would it do, if a man told a good strong lie for the sake of the good and for the Christian church ... a lie out of necessity, a useful lie, a helpful lie, such lies would not be against God, he would accept them."
"I cannot forbid a person to marry several wives, for it does not contradict Scripture."
"When the Gospel is preached unto faith, hope, love, and patience, God gives His wonder-working Spirit. Paul reminds the Galatians of this. "God had not only brought you to faith by my preaching. He had also sanctified you to bring forth the fruits of faith. And one of the fruits of your faith was that you loved me so devotedly that you were willing to pluck out your eyes for me." To love a fellow-man so devotedly as to be ready to bestow upon him money, goods, eyes in order to secure his salvation, such love is the fruit of the Holy Spirit."
"When we pay attention to reason, God seems to propose impossible matters in the Christian Creed. To reason it seems absurd that Christ should offer His body and blood in the Lord's Supper; that Baptism should be the washing of regeneration; that the dead shall rise; that Christ the Son of God was conceived in the womb of the Virgin Mary, etc. Reason shouts that all this is preposterous. Are you surprised that reason thinks little of faith? Reason thinks it ludicrous that faith should be the foremost service any person can render unto God. Let your faith supplant reason."
"Therefore we Christians, in turn, are obliged not to tolerate their [the Jews'] wanton and conscious blasphemy."
"What shall we Christians do with this rejected and condemned people, the Jews? ... First to set fire to their synagogues or schools and to bury and cover with dirt whatever will not burn ... This is to be done in honor of our Lord and of Christendom, so that God might see that we are Christians, and do not condone or knowingly tolerate such public lying, cursing, and blaspheming of his Son and of his Christians. ... Second, I advise that their houses also be razed and destroyed. ... Third, I advise that all their prayer books and Talmudic writings, in which such idolatry, lies, cursing and blasphemy are taught, be taken from them. ... Fourth, I advise that their rabbis be forbidden to teach henceforth on pain of loss of life and limb. ... Fifth, I advise that safe-conduct on the highways be abolished completely for the Jews. ... Sixth, I advise that usury be prohibited to them, and that all cash and treasure of silver and gold be taken from them and put aside for safekeeping. ... Seventh, I commend putting a flail, an ax, a hoe, a spade, a distaff, or a spindle into the hands of young, strong Jews and Jewesses and letting them earn their bread in the sweat of their brow, as was imposed on the children of Adam (Gen 3[:19])."
"Be a sinner and sin strongly, but more strongly have faith and rejoice in Christ."
"Prayer is a strong wall and fortress of the church; it is a goodly Christian weapon."
"The Jews (as we in sacred Writ are told) To buy a God gave Aaron all their Gold. But Christians now (Times are so monstrous odd) To heap up Gold will even sell their God."
"Had it been published by a voice from heaven, that twelve poor men, taken out of boats and creeks, without any help of learning, should conquer the world to the cross, it might have been thought an illusion against all reason of men; yet we know it was undertaken and accomplished by them."
"Don't you see that the appalling history of sectarianism, persecution, heresy hunting, shows you that this way of thinking about the world is intrinsically unsound?"
"The universe, the whole mass of all things that are, is corporeal, that is to say body, and hath dimensions of magnitude, length breadth and depth. Every part of the universe is body and that which is not body is no part of the universe. And because the universe is all, that which is no part of it is nothing. Consequently, nowhere."
"[T]he universe, that is, the whole mass of all things that are, is corporeal, that is to say, body, and hath the dimensions of magnitude, namely length, breadth, and depth: also every part of body is likewise body and hath the like dimensions; and consequently every part of the universe is body, and that which is not body is no part of the universe: and because the universe is all, that which is no part of it is nothing, and consequently nowhere. Nor does it follow from hence that spirits are nothing: for they have dimensions and are therefore really bodies; though that name in common speech be given to such bodies only as are visible or palpable; that is, that have some degree of opacity: but for spirits, they call them incorporeal, which is a name of more honour, and may therefore with more piety be attributed to God Himself; in whom we consider not what attribute expresseth best His nature, which is incomprehensible, but what best expresseth our desire to honour Him."
"For after the Bible was translated into English, every man, nay every boy and wench, that could read English, thought they spoke with God Almighty, and understood what he said, when by a certain number of chapters a day they had read the Scriptures once or twice over. The reverence and obedience due to the Reformed Church here, and to the bishops and pastors therein, was cast off, and every man became a judge of religion, and an interpreter of the Scriptures to himself.... I confess this licence of interpreting the Scripture was the cause of so many several sects, as have lain hid until the beginning of the late King's reign, and did then appear to the disturbance of the commonwealth."
"I have often wondered, that persons who make a boast of professing the Christian religion, namely, love, joy, peace, temperance, and charity to all men, should quarrel with such rancorous animosity, and display daily towards one another such bitter hatred, that this, rather than the virtues they claim, is the readiest criterion of their faith. Matters have long since come to such a pass, that one can only pronounce a man Christian, Turk, Jew, or Heathen, by his general appearance and attire, by his frequenting this or that place of worship, or employing the phraseology of a particular sect—as for manner of life, it is in all cases the same."
"I must at this juncture declare that those doctrines which certain churches put forward concerning Christ, I neither affirm nor deny, for I freely confess that I do not grasp them."
"Let divines and philosophers, statemen and patriots, unite their endeavours to renovate the age by impressing the minds of men with the importance of educating little boys and girls; of inculcating in the minds of youth the fear and love of the Deity...in short leading them in the study and practice of the exalted virtues of the Christian system...."
"A few persons of an odious and despised country could not have filled the world with believers, had they not shown undoubted credentials from the divine person who sent them on such a message."
"As the government of the United States is not, in any sense, founded on the Christian religion; as it has in itself no character of enmity against the laws, religion or tranquility of Musselmen [Muslims] ... it is declared ... that no pretext arising from religious opinion shall ever product an interruption of the harmony existing between the two countries."
"Before the christian religion had, as it were, humanized the idea of the divinity, and brought it somewhat nearer to us, there was very little said of the love of God. The followers of Plato have something of it, and only something. The other writes of pagan antiquity, whether poets or philosophers, nothing at all."
"The Cross! There, and there only (though the deist rave, And atheist, if Earth bears so base a slave); There and there only, is the power to save."
"I think it better to keep a profound silence with regard to the Christian fables, which are canonized by their antiquity and the credulity of absurd and insipid people."
"[N]either antiquity nor any other nation has imagined a more atrocious and blasphemous absurdity than that of eating God. This is how Christians treat the autocrat of the universe."
"The Christians, in the course of their intestine dissensions, have inflicted far greater severities on each other than they had experienced from the zeal of infidels."
"The virtue of the primitive Christians, like that of the first Romans, was very frequently guarded by poverty and ignorance."
"The ancient and popular doctrine of the Millennium was intimately connected with the second coming of Christ. As the works of the creation had been finished in six days, their duration in their present state, according to a tradition which was attributed to the prophet Elijah, was fixed to six thousand years. By the same analogy it was inferred that this long period of labour and contention, which was now almost elapsed, would be succeeded by a joyful Sabbath of a thousand years; and that Christ, with the triumphant band of the saints and the elect who had escaped death, or who had been miraculously revived, would reign upon earth till the time appointed for the last and general resurrection. So pleasing was this hope to the mind of believers, that the new Jerusalem, the seat of this blissful kingdom, was quickly adorned with all the gayest colours of the imagination. ... Though it might not be universally received, it appears to have been the reigning sentiment of the orthodox believers; and it seems so well adapted to the desires and apprehensions of mankind, that it must have contributed in a very considerable degree to the progress of the Christian faith. But when the edifice of the church was almost completed, the temporary support was laid aside. The doctrine of Christ's reign upon earth was at first treated as a profound allegory, was considered by degrees as a doubtful and useless opinion, and was at length rejected as the absurd invention of heresy and fanaticism. A mysterious prophecy, which still forms a part of the sacred canon, but which was thought to favour the exploded sentiment, has very narrowly escaped the proscription of the church."
"Whilst the happiness and glory of a temporal reign were promised to the disciples of Christ, the most dreadful calamities were denounced against an unbelieving world. ... A regular series was prepared of all the moral and physical evils which can afflict a flourishing nation; intestine discord, and the invasion of the fiercest barbarians from the unknown regions of the North; pestilence and famine, comets and eclipses, earthquakes and inundations. The calmest and most intrepid sceptic could not refuse to acknowledge that the destruction of the present system of the world by fire was in itself extremely probable. The Christian, who founded his belief much less on the fallacious arguments of reason than on the authority of tradition and the interpretation of Scripture, expected it with terror and confidence as a certain and approaching event; and as his mind was perpetually filled with the solemn idea, he considered every disaster that happened to the empire as an infallible symptom of an expiring world."
"The condemnation of the wisest and most virtuous of the Pagans, on account of their ignorance or disbelief of the divine truth, seems to offend the reason and the humanity of the present age. But the primitive church, whose faith was of a much firmer consistence, delivered over, without hesitation, to eternal torture the far greater part of the human species."
"The chaste severity of the fathers in whatever related to the commerce of the two sexes flowed from the same principle—their abhorrence of every enjoyment which might gratify the sensual and degrade the spiritual nature of man. It was their favourite opinion, that if Adam had preserved his obedience to the Creator, he would have lived for ever in a state of virgin purity, and that some harmless mode of vegetation might have peopled paradise with a race of innocent and immortal beings. The use of marriage was permitted only to his fallen posterity, as a necessary expedient to continue the human species, and as a restraint, however imperfect, on the natural licentiousness of desire. The enumeration of the very whimsical laws which they most circumstantially imposed on the marriage-bed would force a smile from the young and a blush from the fair. It was their unanimous sentiment that a first marriage was adequate to all the purposes of nature and of society. The sensual connection was refined into a resemblance of the mystic union of Christ with his church, and was pronounced to be indissoluble either by divorce or by death. The practice of second nuptials was branded with the name of a legal adultery; and the persons who were guilty of so scandalous an offence against Christian purity were soon excluded from the honours, and even from the arms, of the church. Since desire was imputed as a crime, and marriage was tolerated as a defect, it was consistent with the same principles to consider a state of celibacy as the nearest approach to the Divine perfection."
"The names of Seneca, of the elder and the younger Pliny, of Tacitus, of Plutarch, of Galen, of the slave Epictetus, and of the emperor Marcus Antoninus, adorn the age in which they flourished, and exalt the dignity of human nature. They filled with glory their respective stations, either in active or contemplative life; their excellent understandings were improved by study; philosophy had purified their minds from the prejudices of the popular superstition; and their days were spent in the pursuit of truth and the practice of virtue. Yet all these sages (it is no less an object of surprise than of concern) overlooked or rejected the perfection of the Christian system. Their language or their silence equally discover their contempt for the growing sect which in their time had diffused itself over the Roman empire. Those among them who condescend to mention the Christians consider them only as obstinate and perverse enthusiasts, who exacted an implicit submission to their mysterious doctrines, without being able to produce a single argument that could engage the attention of men of sense and learning."
"[H]ow shall we excuse the supine inattention of the Pagan and philosophic world to those evidences which were presented by the hand of Omnipotence, not to their reason, but to their senses? During the age of Christ, of his apostles, and of their first disciples, the doctrine which they preached was confirmed by innumerable prodigies. The lame walked, the blind saw, the sick were healed, the dead were raised, daemons were expelled, and the laws of Nature were frequently suspended for the benefit of the church. ... Under the reign of Tiberius, the whole earth, or at least a celebrated province of the Roman empire, was involved in a preternatural darkness of three hours. Even this miraculous event, which ought to have excited the wonder, the curiosity, and the devotion of mankind, passed without notice in an age of science and history. It happened during the lifetime of Seneca and the elder Pliny, who must have experienced the immediate effects, or received the earliest intelligence, of the prodigy. Each of these philosophers, in a laborious work, has recorded all the great phenomena of Nature, earthquakes, meteors, comets, and eclipses, which his indefatigable curiosity could collect. Both the one and the other have omitted to mention the greatest phenomenon to which the mortal eye has been witness since the creation of the globe."
"But the most interesting conquest of the Seljukian Turks was that of Jerusalem, which soon became the theatre of nations. In their capitulation with Omar, the inhabitants had stipulated the assurance of their religion and property; ... and the sepulchre of Christ, with the church of the Resurrection, was still left in the hands of his votaries. Of these votaries, the most numerous and respectable portion were strangers to Jerusalem: the pilgrimages to the Holy Land had been stimulated, rather than suppressed, by the conquest of the Arabs; ... The harmony of prayer in so many various tongues, the worship of so many nations in the common temple of their religion, might have afforded a spectacle of edification and peace; but the zeal of the Christian sects was imbittered by hatred and revenge; and in the kingdom of a suffering Messiah, who had pardoned his enemies, they aspired to command and persecute their spiritual brethren."
"About four hundred and sixty years after the conquest of Omar, the holy city was rescued from the Mahometan yoke. In the pillage of public and private wealth, the adventurers had agreed to respect the exclusive property of the first occupant; and the spoils of the great mosque, seventy lamps and massy vases of gold and silver, rewarded the diligence, and displayed the generosity, of Tancred. A bloody sacrifice was offered by his mistaken votaries to the God of the Christians: resistance might provoke but neither age nor sex could mollify, their implacable rage: they indulged themselves three days in a promiscuous massacre; and the infection of the dead bodies produced an epidemical disease. After seventy thousand Moslems had been put to the sword, and the harmless Jews had been burnt in their synagogue, they could still reserve a multitude of captives, whom interest or lassitude persuaded them to spare. ... Bareheaded and barefoot, with contrite hearts, and in an humble posture, they ascended the hill of Calvary, amidst the loud anthems of the clergy; kissed the stone which had covered the Savior of the world; and bedewed with tears of joy and penitence the monument of their redemption. ... nor shall I believe that the most ardent in slaughter and rapine were the foremost in the procession to the holy sepulchre."
"If we go back to the beginning, we shall find that ignorance and fear created the gods; that fancy, enthusiasm, or deceit adorned them; that weakness worships them; that credulity preserves them and that custom, respect and tyranny support them in order to make the blindness of men serve their own interests. If the ignorance of nature gave birth to gods, the knowledge of nature is calculated to destroy them."
"Christianity neither is, nor ever was, a part of the common law."
"In the middle ages of Christianity opposition to the State opinions was hushed. The consequence was, Christianity became loaded with all the Romish follies. Nothing but free argument, raillery & even ridicule will preserve the purity of religion."
"Millions of innocent men, women and children, since the introduction of Christianity, have been burnt, tortured, fined, imprisoned: yet we have not advanced one inch towards uniformity. What has been the effect of coercion? To make one half the world fools, and the other half hypocrites. To support roguery and error all over the earth. Let us reflect that it is inhabited by a thousand millions of people. That these profess probably a thousand different systems of religion. That ours is but one of that thousand. That if there be but one right, and ours that one, we should wish to see the 999 wandering sects gathered into the fold of truth. But against such a majority we cannot effect this by force. Reason and persuasion are the only practicable instruments. To make way for these, free inquiry must be indulged; and how can we wish others to indulge it while we refuse it ourselves. But every state, says an inquisitor, has established some religion. "No two, say I, have established the same." Is this a proof of the infallibility of establishments? Our sister states of Pennsylvania and New York, however, have long subsisted without any establishment at all."
"I doubt whether the people of this country would suffer an execution for heresy, or a three years imprisonment for not comprehending the mysteries of the trinity."
"Your reason is now mature enough to examine this object [religion]. In the first place divest yourself of all bias in favour of novelty & singularity of opinion. Indulge them in any other subject rather than that of religion. It is too important, & the consequences of error may be too serious. On the other hand shake off all the fears & servile prejudices under which weak minds are servilely crouched. Fix reason firmly in her seat, and call to her tribunal every fact, every opinion. Question with boldness even the existence of a god; because, if there be one, he must more approve of the homage of reason, than that of blindfolded fear. You will naturally examine first the religion of your own country. Read the bible then, as you would read Livy or Tacitus. ... But those facts in the bible which contradict the laws of nature, must be examined with more care, and under a variety of faces. ... Examine upon what evidence his pretensions are founded, and whether that evidence is so strong as that its falsehood would be more improbable than a change in the laws of nature in the case he relates. For example in the book of Joshua we are told the sun stood still several hours. Were we to read that fact in Livy or Tacitus we should class it with their showers of blood, speaking of statues, beasts, etc. But it is said that the writer of that book was inspired. Examine therefore candidly what evidence there is of his having been inspired. The pretension is entitled to your inquiry, because millions believe it. On the other hand you are astronomer enough to know how contrary it is to the law of nature that a body revolving on its axis as the earth does, should have stopped, should not by that sudden stoppage have prostrated animals, trees, buildings, and should after a certain time have resumed its revolution, & that without a second general prostration. Is this arrest of the earth's motion, or the evidence which affirms it, most within the law of probabilities? You will next read the new testament. It is the history of a personage called Jesus. Keep in your eye the opposite pretensions I. of those who say he was begotten by god, born of a virgin, suspended & reversed the laws of nature at will, & ascended bodily into heaven: and 2. of those who say he was a man of illegitimate birth, of a benevolent heart, enthusiastic mind, who set out without pretensions to divinity, ended in believing them, & was Punished capitally for sedition by being gibbeted according to the Roman law which punished the first commission of that offence by whipping, & the second by exile or death in furcâ. ... Do not be frightened from this inquiry by any fear of it's consequences. If it ends in a belief that there is no god, you will find incitements to virtue in the comfort & pleasantness you feel in it's exercise, and the love of others which it will procure you. If you find reason to believe there is a god, a consciousness that you are acting under his eye, & that he approves you, will be a vast additional incitement; if that there be a future state, the hope of a happy existence in that increases the appetite to deserve it; if that Jesus was also a god, you will be comforted by a belief of his aid and love. In fine, I repeat that you must lay aside all prejudice on both sides, & neither believe nor reject anything because any other persons, or description of persons have rejected or believed it. Your own reason is the only oracle given you by heaven, and you are answerable not for the rightness but uprightness of the decision. I forgot to observe when speaking of the new testament that you should read all the histories of Christ, as well of those whom a council of ecclesiastics have decided for us to be Pseudo-evangelists, as those they named Evangelists. Because these Pseudo-evangelists pretended to inspiration as much as the others, and you are to judge their pretensions by your own reason, & not by the reason of those ecclesiastics. Most of these are lost. There are some however still extant, collected by Fabricius which I will endeavor to get & send you."
"Christianity possesses the great advantage over Judaism of being represented as coming from the mouth of the first Teacher not as a statutory but as a moral religion, and as thus entering into the closest relation with reason so that, through reason, it was able of itself, without historical learning, to be spread at all times and among all peoples with the greatest trustworthiness."
"What influence in fact have ecclesiastical establishments had on Civil Society? In some instances they have been seen to erect a spiritual tyranny on the ruins of the Civil authority; in many instances they have been seen upholding the thrones of political tyranny: in no instance have they been seen the guardians of the liberties of the people. Rulers who wished to subvert the public liberty, may have found an established Clergy convenient auxiliaries. A just Government instituted to secure & perpetuate it needs them not."
"During almost fifteen centuries has the legal establishment of Christianity been on trial. What have been its fruits? More or less in all places, pride and indolence in the Clergy, ignorance and servility in the laity, in both, superstition, bigotry and persecution."
"To compare Christianity to other religions is mere wrangling; several striking characteristics exclude all comparisons. This is not the place to list them; just a word will be enough. Who can show us one other religion founded on miracles and revealing incomprehensible dogmas, yet believed for eighteen centuries by the greater part of mankind and defended down through the ages by the greatest men of each era from Origen to Pascal, despite the utmost efforts of an enemy sect that, from Celsus to Condorcet, has never ceased its bellowing?"
"It is necessary that the Christian should distinguish himself from the crowd by a singular conduct; that he should walk almost alone along a by-lane, where he will have to suffer the scorn and sneers of false Christians."
"Chose admirable! la religion chrétienne, qui ne semble avoir d'objet que la félicité de l'autre vie, fait encore notre bonheur dans celle-ci."
