Context: My opinion concerning God differs widely from that which is ordinarily defended by modern Christians. For I hold that God is of all things the cause immanent, as the phrase is, not transient. I say that all things are in God and move in God, thus agreeing with Paul, and, perhaps, with all the ancient philosophers, though the phraseology may be different; I will even venture to affirm that I agree with all the ancient Hebrews, in so far as one may judge from their traditions, though these are in many ways corrupted. The supposition of some, that I endeavour to prove in the Tractatus Theologico-Politicus the unity of God and Nature (meaning by the latter a certain mass or corporeal matter), is wholly erroneous.
As regards miracles, I am of opinion that the revelation of God can only be established by the wisdom of the doctrine, not by miracles, or in other words by ignorance.

Context: If I had as clear an idea of ghosts, as I have of a triangle or a circle, I should not in the least hesitate to affirm that they had been created by God; but as the idea I possess of them is just like the ideas, which my imagination forms of harpies, gryphons, hydras, &c., I cannot consider them as anything but dreams, which differ from God as totally as that which is not differs from that which is.<!--pp. 382-383

Letter 56 (60), to Hugo Boxel (1674) http://oll.libertyfund.org/?option=com_staticxt&staticfile=show.php%3Ftitle=1711&chapter=144218&layout=html&Itemid=27
Context: When you say that if I deny, that the operations of seeing, hearing, attending, wishing, &c., can be ascribed to God, or that they exist in him in any eminent fashion, you do not know what sort of God mine is; I suspect that you believe there is no greater perfection than such as can be explained by the aforesaid attributes. I am not astonished; for I believe that, if a triangle could speak, it would say, in like manner, that God is eminently triangular, while a circle would say that the divine nature is eminently circular. Thus each would ascribe to God its own attributes, would assume itself to be like God, and look on everything else as ill-shaped.
The briefness of a letter and want of time do not allow me to enter into my opinion on the divine nature, or the questions you have propounded. Besides, suggesting difficulties is not the same as producing reasons. That we do many things in the world from conjecture is true, but that our redactions are based on conjecture is false. In practical life we are compelled to follow what is most probable; in speculative thought we are compelled to follow truth. A man would perish of hunger and thirst, if he refused to eat or drink, till he had obtained positive proof that food and drink would be good for him. But in philosophic reflection this is not so. On the contrary, we must take care not to admit as true anything, which is only probable. For when one falsity has been let in, infinite others follow.
Again, we cannot infer that because sciences of things divine and human are full of controversies and quarrels, therefore their whole subject-matter is uncertain; for there have been many persons so enamoured of contradiction, as to turn into ridicule geometrical axioms.

Context: If you find the light of Scripture clearer than the light of reason (which also is given us by divine wisdom), you are doubtless right in your own conscience in making your reason yield. For my part, since I plainly confess that I do not understand the Scriptures, though I have spent many years upon them, and since I know that when once I have a firm proof I cannot by any course of thought come to doubt of it, I rest wholly upon that which my understanding commends to me, without any suspicion that I am deceived therein, or that the Scriptures, even though I do not search them, can speak against it. For one truth cannot conflict with another, as I have already clearly shown in my Appendix to the "Principles of Descartes"... But if in any case I did find error in that which I have collected from my natural understanding, I should count it good fortune, since I enjoy life, and endeavour to pass it not in weeping and sighing, but in peace, joy, and cheerfulness, and from time to time climb thereby a step higher. I know, meanwhile (which is the highest pleasure of all), that all things happen by the power and unchangeable decree of the most perfect Being.

Letter 21 (73) to Henry Oldenburg, November (1675)
Variant translation: The eternal wisdom of God … has shown itself forth in all things, but chiefly in the mind of man, and most of all in Jesus Christ.
Context: I do not think it necessary for salvation to know Christ according to the flesh : but with regard to the Eternal Son of God, that is the Eternal Wisdom of God, which has manifested itself in all things and especially in the human mind, and above all in Christ Jesus, the case is far otherwise. For without this no one can come to a state of blessedness, inasmuch as it alone teaches, what is true or false, good or evil. And, inasmuch as this wisdom was made especially manifest through Jesus Christ, as I have said, his disciples preached it, in so far as it was revealed to them through him, and thus showed that they could rejoice in that spirit of Christ more than the rest of mankind. The doctrines added by certain churches, such as that God took upon himself human nature, I have expressly said that I do not understand; in fact, to speak the truth, they seem to me no less absurd than would a statement, that a circle had taken upon itself the nature of a square. This I think will be sufficient explanation of my opinions concerning the three points mentioned. Whether it will be satisfactory to Christians you will know better than I.

Context: Philosophers conceive of the passions which harass us as vices into which men fall by their own fault, and, therefore, generally deride, bewail, or blame them, or execrate them, if they wish to seem unusually pious. And so they think they are doing something wonderful, and reaching the pinnacle of learning, when they are clever enough to bestow manifold praise on such human nature, as is nowhere to be found, and to make verbal attacks on that which, in fact, exists. For they conceive of men, not as they are, but as they themselves would like them to be. Whence it has come to pass that, instead of ethics, they have generally written satire, and that they have never conceived a theory of politics, which could be turned to use, but such as might be taken for a chimera, or might have been formed in Utopia, or in that golden age of the poets when, to be sure, there was least need of it. Accordingly, as in all sciences, which have a useful application, so especially in that of politics, theory is supposed to be at variance with practice; and no men are esteemed less fit to direct public affairs than theorists or philosophers.

Matthew Stewart, The Courtier and the Heretic (2006)
Context: According to the seventeenth-century way of thinking, an atheist was by definition a decadent. If there was no God (or, at least, no providential, rewarding-and-punishing God of the sort worshipped in all the traditional religions), the reasoning went, then everything is permitted. So a non-beliver would be expected to indulge in all manner of sensual stimulation... to lie, cheat, and steal...
Spinoza, according to all seventeenth-century interpreters, rejected all the traditional ideas about God; he was indesputably a heretic. Yet his manner of living was humble and apparently free of vice. Then, as now, the philosopher seemed a living oxymoron: he was an ascetic sensualist, a spiritual materialist, a sociable hermit, a secular saint. How could his life have been so good, the critics asked, when his philosophy was so bad?<!--p.73

Writ of expulsion from the Jewish community, as translated in Benedict de Spinoza : His Life, Correspondence, and Ethics (1870) by Robert Willis
Context: With the judgment of the angels and the sentence of the saints, we anathematize, execrate, curse and cast out Baruch de Espinoza, the whole of the sacred community assenting, in presence of the sacred books with the six-hundred-and-thirteen precepts written therein, pronouncing against him the malediction wherewith Elisha cursed the children, and all the maledictions written in the Book of the Law. Let him be accursed by day, and accursed by night; let him be accursed in his lying down, and accursed in his rising up; accursed in going out and accursed in coming in. May the Lord never more pardon or acknowledge him; may the wrath and displeasure of the Lord burn henceforth against this man, load him with all the curses written in the Book of the Law, and blot out his name from under the sky; may the Lord sever him from all the tribes of Israel, weight him with all the maledictions of the firmament contained in the Book of Law; and may all ye who are obedient to the Lord your God be saved this day.
Hereby then are all admonished that none hold converse with him by word of mouth, none hold communication with him by writing; that no one do him any service, no one abide under the same roof with him, no one approach within four cubits' length of him, and no one read any document dictated by him, or written by his hand.

James Clerk Maxwell, Matter and Motion (1876)
Context: Descartes... fell back on his original confusion of matter with space—space being, according to him, the only form of substance, and all existing things but affections of space. This error... forms one of the ultimate foundations of the system of Spinoza.

Context: This impels me, before going into your reasons, to set forth briefly my opinion on the question, whether the world was made by chance. But I answer, that as it is clear that chance and necessity are two contraries, so is it also clear, that he, who asserts the world to be a necessary effect of the divine nature, must utterly deny that the world has been made by chance; whereas, he who affirms that God need not have made the world, confirms, though in different language, the doctrine that it has been made by chance; inasmuch as he maintains that it proceeds from a wish, which might never have been formed. However, as this opinion and theory is on the face of it absurd, it is commonly very unanimously admitted, that God's will is eternal, and has never been indifferent; hence... the world is a necessary effect of the divine nature. Let them call it will, understanding, or any name they like, they come at last to the same conclusion, that under different names they are expressing one and the same thing. If you ask them, whether the divine will does not differ from the human, they answer, that the former has nothing in common with the latter except its name; especially as they generally admit that God's will, understanding, intellect, essence, and nature are all identical; so I... lest I... confound the divine nature with the human, do not assign to God human attributes, such as will, understanding, attention, hearing, &c. I therefore say, as I have said already, that the world is a necessary effect of the divine nature, and that it has not been made by chance. I think this is enough to persuade you, that the opinion of those (if such there be) who say that the world has been made by chance, is entirely contrary to mine; and relying on this hypothesis, I proceed to examine those reasons which lead you to infer the existence of all kinds of ghosts.<!--pp. 381-382

Richard Feynman, in The Pleasure of Finding Things Out (1999), Ch. 9. The Smartest Man in the World
Context: My son is taking a course in philosophy, and last night we were looking at something by Spinoza and there was the most childish reasoning! There were all these attributes, and Substances, and all this meaningless chewing around, and we started to laugh. Now how could we do that? Here's this great Dutch philosopher, and we're laughing at him. It's because there's no excuse for it! In the same period there was Newton, there was Harvey studying the circulation of the blood, there were people with methods of analysis by which progress was being made! You can take every one of Spinoza's propositions, and take the contrary propositions, and look at the world and you can't tell which is right.

Georg Wilhelm Friedrich Hegel, in Lectures on the History of Philosophy (1896), Vol. 3, Ch. I : The Metaphysics of the Understanding, § 2 : Spinoza, p. 283
Context: The fact is that Spinoza is made a testing-point in modern philosophy, so that it may really be said: You are either a Spinozist or not a philosopher at all.

George Boole, An Investigation of the Laws of Thought (1854) Ch. 13. Clarke and Spinoza, pp. 216-217. https://books.google.com/books?id=DqwAAAAAcAAJ&pg=PA216
Context: It is not possible, I think, to rise from the perusal of the arguments of Clark and Spinoza without a deep conviction of the futility of all endeavors to establish, entirely à priori, the existence of an Infinite Being, His attributes, and His relation to the universe. The fundamental principle of all such speculations, viz. that whatever we can clearly conceive, must exist, fails to accomplish its end, even when its truth is admitted. For how shall the finite comprehend the infinite? Yet must the possibility of such conception be granted, and in something more than the sense of a mere withdrawal of the limits of phænomal existence, before any solid ground can be established for the knowledge, à priori, of things infinite and eternal.

Context: I make this chief distinction between religion and superstition, that the latter is founded on ignorance, the former on knowledge; this, I take it, is the reason why Christians are distinguished from the rest of the world, not by faith, nor by charity, nor by the other fruits of the Holy Spirit, but solely by their opinions, inasmuch as they defend their cause, like everyone else, by miracles, that is by ignorance, which is the source of all malice; thus they turn a faith, which may be true, into superstition.

Letter to Hugo Boxel (Oct. 1674) The Chief Works of Benedict de Spinoza (1891) Tr. R. H. M. Elwes, Vol. 2, Letter 58 (54).
Context: Beauty, my dear Sir, is not so much a quality of the object beheld, as an effect in him who beholds it. If our sight were longer or shorter, or if our constitution were different, what now appears beautiful to us would seem misshapen, and what we now think misshapen we should regard as beautiful. The most beautiful hand seen through the microscope will appear horrible. Some things are beautiful at a distance, but ugly near; thus things regarded in themselves, and in relation to God, are neither ugly nor beautiful. Therefore, he who says that God has created the world, so that it might be beautiful, is bound to adopt one of the two alternatives, either that God created the world for the sake of men's pleasure and eyesight, or else that He created men's pleasure and eyesight for the sake of the world. Now, whether we adopt the former or the latter of these views, how God could have furthered His object by the creation of ghosts, I cannot see. Perfection and imperfection are names which do not differ much from the names beauty and ugliness.<!--p. 382

H. L. Mencken, Treatise on the Gods (1930)
Context: It was not until the Twelfth Century of our era that the Pentateuch as a whole was subjected to rational scrutiny. The man who undertook the ungrateful task was a learned Spanish rabbi, Abraham ben Meir ibn Esra. He unearthed many absurdities, but... it was not until five hundred years later that anything properly describable as scientific criticism... came into being. Its earliest shining lights were the English philosopher Thomas Hobbes [with his Leviathan], and the Amsterdam Jew, Baruch Spinoza. Spinoza's "Tractatus Theologico-politicus", published in 1670, made the first really formidable onslaught upon the inspired inerrancy of the Pentateuch. It called attention to scores of transparent imbecilities … including a dozen or more palpable geographical and historical impossibilities … The answer of constituted authorities was to suppress the "Tractatus", but enough copies got out to reach the proper persons, and ever since then the Old Testament has been under searching and devastating examination.

William Boulting, in Giordano Bruno: His Life, Thought, and Martyrdom (1916) online excerpt http://www.class.uidaho.edu/mickelsen/texts/Bruno's%20Eroici.htm
Context: Of Bruno, as of Spinoza, it may be said that he was "God-intoxicated." He felt that the Divine Excellence had its abode in the very heart of Nature and within his own body and spirit. Indwelling in every dewdrop as in the innumerable host of heaven, in the humblest flower and in the mind of man, he found the living spirit of God, setting forth the Divine glory, making the Divine perfection and inspiring with the Divine love.

XII, 95
On the Improvement of the Understanding (1662)
Context: A definition, if it is to be called perfect, must explain the inmost essence of a thing, and must take care not to substitute for this any of its properties. In order to illustrate my meaning, without taking an example which would seem to show a desire to expose other people's errors, I will choose the case of something abstract, the definition of which is of little moment. Such is a circle. If a circle be defined as a figure, such that all straight lines drawn from the center to the circumference are equal, every one can see that such a definition does not in the least explain the essence of a circle, but solely one of its properties. Though, as I have said, this is of no importance in the case of figures and other abstractions, it is of great importance in the case of physical beings and realities, for the properties of things are not understood so long as their essences are unknown. If the latter be passed over, there is necessarily a perversion of the succession of ideas which should reflect the succession of nature, and we go far astray from our object.

Source: Political Treatise (1677), Ch. 1, Introduction; section 4
Context: I have laboured carefully, not to mock, lament, or execrate human actions, but to understand them; and, to this end, I have looked upon passions, such as love, hatred, anger, envy, ambition, pity, and the other perturbations of the mind, not in the light of vices of human nature, but as properties, just as pertinent to it, as are heat, cold, storm, thunder, and the like to the nature of the atmosphere, which phenomena, though inconvenient, are yet necessary, and have fixed causes, by means of which we endeavour to understand their nature, and the mind has just as much pleasure in viewing them aright, as in knowing such things as flatter the senses

Arthur Schopenhauer, in The World as Will and Representation (1818; 1844), Vol. I, p. 422, n. 2
Context: [From Schopenhauer's assessments of other philosophers] Bruno and Spinoza are to be entirely excepted. Each stands by himself and alone; and they do not belong either to their age or to their part of the globe, which rewarded the one with death, and the other with persecution and ignominy. Their miserable existence and death in this Western world are like that of a tropical plant in Europe. The banks of the Ganges were their spiritual home; there, they would have led a peaceful and honoured life among men of like mind.

Source: Political Treatise (1677), Ch. 2, Of Natural Right
Context: In the state of nature, wrong-doing is impossible; or, if anyone does wrong, it is to himself, not to another. For no one by the law of nature is bound to please another, unless he chooses, nor to hold anything to be good or evil, but what he himself, according to his own temperament, pronounces to be so; and, to speak generally, nothing is forbidden by the law of nature, except what is beyond everyone's power.<!-- 23

Context: Through the seventeenth and eighteenth centuries, Bruno's ideas were widely imparted, borrowed, sounded; almost never, though, with the name Giordano Bruno attached to them. Kepler once chided Galileo for omitting his debt to Bruno; yet, we can discern Kepler's own indifference … Later generations would evoke Bruno's writings to the phrase, without quoting or acknowledging him. Recent scholarship on Spinoza, for example, cites Bruno's powerful exertion on his thought about infinity and on his style. Never does Spinoza cite Bruno by name.

Context: Woe to him who in passing should hurl an insult at this gentle and pensive head. He would be punished, as all vulgar souls are punished, by his very vulgarity, and by his incapacity to conceive what is divine. This man, from his granite pedestal, will point out to all men the way of blessedness which he found; and ages hence, the cultivated traveler, passing by this spot, will say in his heart, "The truest vision ever had of God came, perhaps, here."

Friedrich Nietzsche, in a postcard to Franz Overbeck, Sils-Maria (30 July 1881) as translated by Walter Kaufmann in The Portable Nietzsche (1954)
Context: I am utterly amazed, utterly enchanted! I have a precursor, and what a precursor! I hardly knew Spinoza : that I should have turned to him just now, was inspired by "instinct". Not only is his overtendency like mine — namely, to make all knowledge the most powerful affect — but in five main points of his doctrine I recognize myself; this most unusual and loneliest thinker is closest to me precisely in these matters : he denies the freedom of the will, teleology, the moral world-order, the unegoistic, and evil. Even though the divergencies are admittedly tremendous, they are due more to the difference in time, culture, and science. In summa: my lonesomeness, which, as on very high mountains, often made it hard for me to breathe and make my blood rush out, is now at least a twosomeness. Strange!

No doubt there are usually more and sharper quarrels between parents and children, than between masters and slaves; yet it advances not the art of household management to change a father's right into a right of property, and count children but as slaves. Slavery, then, and not peace, is furthered by handing the whole authority to one man.

Ernest Renan, at the dedication of a statue to Spinoza in 1882, as quoted in The Story of Philosophy (1962) http://caute.net.ru/spinoza/aln/durant.htm by Will Durant
Context: Woe to him who in passing should hurl an insult at this gentle and pensive head. He would be punished, as all vulgar souls are punished, by his very vulgarity, and by his incapacity to conceive what is divine. This man, from his granite pedestal, will point out to all men the way of blessedness which he found; and ages hence, the cultivated traveler, passing by this spot, will say in his heart, "The truest vision ever had of God came, perhaps, here."

He felt that the Divine Excellence had its abode in the very heart of Nature and within his own body and spirit. Indwelling in every dewdrop as in the innumerable host of heaven, in the humblest flower and in the mind of man, he found the living spirit of God, setting forth the Divine glory, making the Divine perfection and inspiring with the Divine love.

Matthew Stewart, The Courtier and the Heretic (2006)
Context: Like Socrates, Spinoza avers that blessedness comes only from a certain kind of knowledge—specifically, the "knowledge of the union that the mind has with the whole of Nature."
... the life of contemplation is also a life within a certain type of community—specifically, a fellowship of the mind. Like Socrates with his circle of debating partners, or Epicurus in his garden with his intellectual companions, Spinoza imagines a philosophical future... upon achieving blessedness for himself, he announces in his first treatise, his first step is "to form a society... so that as many as possible may attain it as easily and as surely as possible." For, "the highest good," he claims, is to achieve salvation together with other individuals "if possible."

Context: The religious geniuses of all ages have been distinguished by this kind of religious feeling, which knows no dogma and no God conceived in man's image; so that there can be no church whose central teachings are based on it. Hence it is precisely among the heretics of every age that we find men who were filled with this highest kind of religious feeling and were in many cases regarded by their contemporaries as atheists, sometimes also as saints. Looked at in this light, men like Democritus, Francis of Assisi, and Spinoza are closely akin to one another.

Context: Regarding Spinoza, whom M. Arnauld has called the most impious and most dangerous man of this century, he was truly an Atheist, [i. e., ] he allowed absolutely no Providence dispensing rewards and punishments according to justice.... The God he puts on parade is not like ours; he has no intellect or will.... He fell well short of mastering the art of demonstration; he had only a mediocre knowledge of analysis and geometry; what he knew best was to make lenses for microscopes.

Matthew Stewart, The Courtier and the Heretic (2006)
Context: For Spinoza, philosophy originates in the very personal... feeling of emptiness that in the philosophical tradition has earned the distinguished name of contemptu mundi, the contempt for worldly things, or, better, vanitas.... Spinoza says that... success in life is just a postponement of failure;... pleasure is just a fleeting respite from pain; and... the objects of our striving are vain illusions....
The feeling of vanitas Spinoza describes is... a dire encounter with the prospect of descent into absolute nothingness, a life without significance coming to a meaningless end.... The experience Spinoza records... establishes... the moment of extreme doubt, fear, and uncertainty that precedes the dawn of revelation.... the journey... is one trodden by poets, philosophers, and theologians too numerous to mention, who for millennia have recorded this feeling that life is a useless passion, a wheel of ceaseless striving, a tale told by an idiot, full of sound and fury, signifying nothing, and so on.<!--pp. 55-56

Friedrich Nietzsche, in a postcard to Franz Overbeck, Sils-Maria (30 July 1881) as translated by Walter Kaufmann in The Portable Nietzsche (1954)
Context: I am utterly amazed, utterly enchanted! I have a precursor, and what a precursor! I hardly knew Spinoza : that I should have turned to him just now, was inspired by "instinct". Not only is his overtendency like mine — namely, to make all knowledge the most powerful affect — but in five main points of his doctrine I recognize myself; this most unusual and loneliest thinker is closest to me precisely in these matters : he denies the freedom of the will, teleology, the moral world-order, the unegoistic, and evil. Even though the divergencies are admittedly tremendous, they are due more to the difference in time, culture, and science. In summa: my lonesomeness, which, as on very high mountains, often made it hard for me to breathe and make my blood rush out, is now at least a twosomeness. Strange!

such as the laying down, interpretation, and abrogation of laws, the fortification of cities, deciding on war and peace, &c. But if this charge belong to a council, composed of the general multitude, then the dominion is called a democracy; if the council be composed of certain chosen persons, then it is an aristocracy ; and, if, lastly, the care of affairs of state, and, consequently, the dominion rest with one man, then it has the name of monarchy.

Erich Fromm, in The Sane Society (1955), Ch. 2: Can A Society be Sick?—The Pathology of Normalcy
Context: Spinoza formulated the problem of the socially patterned defect very clearly. He says: "Many people are seized by one and the same affect with great consistency. All his senses are so strongly affected by one object that he believes this object to be present even if it is not. If this happens while the person is awake, the person is believed to be insane. … But if the greedy person thinks only of money and possessions, the ambitious one only of fame, one does not think of them as being insane, but only as annoying; generally one has contempt for them. But factually greediness, ambition, and so forth are forms of insanity, although usually one does not think of them as 'illness.'" These words were written a few hundred years ago; they still hold true, although the defects have been culturally patterned to such an extent now that they are not even generally thought any more to be annoying or contemptible.

Letter 74 (76) to Albert Burgh (1675) http://oll.libertyfund.org/?option=com_staticxt&staticfile=show.php%3Ftitle=1711&chapter=144250&layout=html&Itemid=27
Context: You seem to wish to employ reason, and ask me, "How I know that my philosophy is the best among all that have ever been taught in the world, or are being taught, or ever will be taught?" a question which I might with much greater right ask you; for I do not presume that I have found the best philosophy, I know that I understand the true philosophy. If you ask in what way I know it, I answer: In the same way as you know that the three angles of a triangle are equal to two right angles: that this is sufficient, will be denied by no one whose brain is sound, and who does not go dreaming of evil spirits inspiring us with false ideas like the true. For the truth is the index of itself and of what is false.
But you, who presume that you have at last found the best religion, or rather the best men, on whom you have pinned your credulity, you, "who know that they are the best among all who have taught, do now teach, or shall in future teach other religions. Have you examined all religions, ancient as well as modern, taught here and in India and everywhere throughout the world? And, if you, have duly examined them, how do you know that you have chosen the best" since you can give no reason for the faith that is in you? But you will say, that you acquiesce in the inward testimony of the Spirit of God, while the rest of mankind are ensnared and deceived by the prince of evil spirits. But all those outside the pale of the Romish Church can with equal right proclaim of their own creed what you proclaim of yours.
As to what you add of the common consent of myriads of men and the uninterrupted ecclesiastical succession, this is the very catch-word of the Pharisees. They with no less confidence than the devotees of Rome bring forward their myriad witnesses, who as pertinaciously as the Roman witnesses repeat what they have heard, as though it were their personal experience. Further, they carry back their line to Adam. They boast with equal arrogance, that their Church has continued to this day unmoved and unimpaired in spite of the hatred of Christians and heathen. They more than any other sect are supported by antiquity. They exclaim with one voice, that they have received their traditions from God himself, and that they alone preserve the word of God, both written and unwritten. That all heresies have issued from them, and that they have remained constant through thousands of years under no constraint of temporal dominion, but by the sole efficacy of their superstition, no one can deny. The miracles they tell of would tire a thousand tongues. But their chief boast is that they count a far greater number of martyrs than any other nation, a number which is daily increased by those who suffer with singular constancy for the faith they profess; nor is their boasting false. I myself knew among others of a certain Judah called the faithful, who in the midst of the flames, when he was already thought to be dead, lifted his voice to sing the hymn beginning, "To thee, o God, I offer up my soul", and so singing perished.
