“We forbid each and every one of the faithful of either sex, in virtue of holy obedience and under the above penalties to be incurred automatically, to read, assert, preach, praise, print, publish, or defend them.”

Pope Leo X Exsurge Domine

Exsurge Domine (1520)
Context: With the advice and consent of these our venerable brothers, with mature deliberation on each and every one of the above theses, and by the authority of almighty God, the blessed Apostles Peter and Paul, and our own authority, we condemn, reprobate, and reject completely each of these theses or errors as either heretical, scandalous, false, offensive to pious ears or seductive of simple minds, and against Catholic truth. By listing them, we decree and declare that all the faithful of both sexes must regard them as condemned, reprobated, and rejected…. We restrain all in the virtue of holy obedience and under the penalty of an automatic major excommunication....
Moreover, because the preceding errors and many others are contained in the books or writings of Martin Luther, we likewise condemn, reprobate, and reject completely the books and all the writings and sermons of the said Martin, whether in Latin or any other language, containing the said errors or any one of them; and we wish them to be regarded as utterly condemned, reprobated, and rejected. We forbid each and every one of the faithful of either sex, in virtue of holy obedience and under the above penalties to be incurred automatically, to read, assert, preach, praise, print, publish, or defend them. They will incur these penalties if they presume to uphold them in any way, personally or through another or others, directly or indirectly, tacitly or explicitly, publicly or occultly, either in their own homes or in other public or private places.

“Happiness is not the reward of virtue, but is virtue itself; nor do we delight in happiness because we restrain from our lusts; but on the contrary, because we delight in it, therefore we are able to restrain them.”

Baruch Spinoza (1632–1677) Dutch philosopher

“But think how great a Proportion of Mankind consists of weak and ignorant Men and Women, and of inexperienc’d and inconsiderate Youth of both Sexes, who have need of the Motives of Religion to restrain them from Vice, to support their Virtue, and retain them in the Practice of it till it becomes habitual”

Benjamin Franklin (1706–1790) American author, printer, political theorist, politician, postmaster, scientist, inventor, civic activist, …

Letter to unknown recipient (13 December 1757) http://teachingamericanhistory.org/library/index.asp?document=473. The letter was published as early as 1817 (William Temple Franklin, The Works of Benjamin Franklin, volume VI, pp. 243-244). In 1833 William Wisner ("Don't Unchain the Tiger," American Tract Society, 1833) identified the recipient as probably Thomas Paine, which was echoed by Jared Sparks in his 1840 edition of Franklin's works (volume x, p. 281). (Presumably it would have been directed against The Age of Reason, his deistic work which criticized orthodox Christianity.) Calvin Blanchard responded to Wisner's tract in The Life of Thomas Paine (1860), pp. 73-74, by noting that Franklin died in 1790, while Paine did not begin writing The Age of Reason until 1793, and incorrectly concluded that the letter did not exist. Paul F. Boller, Jr., and John George, included it in They Never Said It: A Book of Fake Quotes, Misquotes, & Misleading Attributions (1989), on p. 28. Moncure Daniel Conway pointed out (The Life of Thomas Paine, 1892, vol I, p. vii) that the recipient could not be Thomas Paine, in that he, unlike Paine, denied a "particular providence". The intended recipient remains unidentified.
Parts of the above have also been rearranged and paraphrased:
I would advise you not to attempt Unchaining The Tiger, but to burn this piece before it is seen by any other person.
If men are so wicked with religion, what would they be if without it?
If men are so wicked with religion, what would they be Without it? Think how many inconsiderate and inexperienced youth of both sexes there are, who have need of the motives of religion to restrain them from vice, to support their virtue, and retain them in the practice of it till it becomes habitual.
Epistles
Context: I have read your Manuscript with some Attention. By the Arguments it contains against the Doctrine of a particular Providence, tho’ you allow a general Providence, you strike at the Foundation of all Religion: For without the Belief of a Providence that takes Cognizance of, guards and guides and may favour particular Persons, there is no Motive to Worship a Deity, to fear its Displeasure, or to pray for its Protection. I will not enter into any Discussion of your Principles, tho’ you seem to desire it; At present I shall only give you my Opinion that tho’ your Reasonings are subtle, and may prevail with some Readers, you will not succeed so as to change the general Sentiments of Mankind on that Subject, and the Consequence of printing this Piece will be a great deal of Odium drawn upon your self, Mischief to you and no Benefit to others. He that spits against the Wind, spits in his own Face. But were you to succeed, do you imagine any Good would be done by it? You yourself may find it easy to live a virtuous Life without the Assistance afforded by Religion; you having a clear Perception of the Advantages of Virtue and the Disadvantages of Vice, and possessing a Strength of Resolution sufficient to enable you to resist common Temptations. But think how great a Proportion of Mankind consists of weak and ignorant Men and Women, and of inexperienc’d and inconsiderate Youth of both Sexes, who have need of the Motives of Religion to restrain them from Vice, to support their Virtue, and retain them in the Practice of it till it becomes habitual, which is the great Point for its Security; And perhaps you are indebted to her originally that is to your Religious Education, for the Habits of Virtue upon which you now justly value yourself. You might easily display your excellent Talents of reasoning on a less hazardous Subject, and thereby obtain Rank with our most distinguish’d Authors. For among us, it is not necessary, as among the Hottentots that a Youth to be receiv’d into the Company of Men, should prove his Manhood by beating his Mother. I would advise you therefore not to attempt unchaining the Tyger, but to burn this Piece before it is seen by any other Person, whereby you will save yourself a great deal of Mortification from the Enemies it may raise against you, and perhaps a good deal of Regret and Repentance. If Men are so wicked as we now see them with Religion what would they be if without it?

“We must love them both, those whose opinions we share and those whose opinions we reject, for both have labored in the search for truth, and both have helped us in finding it.”

Thomas Aquinas (1225–1274) Italian Dominican scholastic philosopher of the Roman Catholic Church

“The only argument the world will listen to now is the argument of personal holiness. It has heard all the rest and rejected them.”

Fulton J. Sheen (1895–1979) Catholic bishop and television presenter

Retreat to Priests, Washington, D.C., p. 19, quoted in Bernard Hayes, C.R., To Live as Jesus Did (Locust Valley, N.Y.: Living Flame Press, 1981), p. 108. There is no book by Sheen with the title Retreat to Priests. Hayes is presumably quoting from a transcription of Sheen's 1974 retreat for priests of the Washington diocese. This was recorded on reel-to-reel tape and later issued in nine 60-minute tapes under the title Renewal and Reconciliation.

“These are some of our American standards. These principles, in the province to which they relate, bestow upon the people all there is to bestow. They recognize in the people all that there is to recognize. They are the ultimates. There is no beyond. They are solely for the benefit and advantage of all the people. If any change is made in these principles it will not be by giving more to the people, but by taking from them something of that which they now have. It cannot be progress. It must be reaction. I do not say that we, as citizens, have always held ourselves to a proper observance of these standards towards each other, but we have nevertheless established them and declared our duty to be obedience to them. This is the American ideal of ordered liberty under the law. It calls for rigid discipline.”

Calvin Coolidge (1872–1933) American politician, 30th president of the United States (in office from 1923 to 1929)

“Men of broader intellect know that there is no sharp distinction betwixt the real and the unreal; that all things appear as they do only by virtue of the delicate individual physical and mental media through which we are made conscious of them; but the prosaic materialism of the majority condemns as madness the flashes of super-sight which penetrate the common veil of obvious empiricism.”

Fiction
Context: In relating the circumstances which have led to my confinement within this refuge for the demented, I am aware that my present position will create a natural doubt of the authenticity of my narrative. It is an unfortunate fact that the bulk of humanity is too limited in its mental vision to weigh with patience and intelligence those isolated phenomena, seen and felt only by a psychologically sensitive few, which lie outside its common experience. Men of broader intellect know that there is no sharp distinction betwixt the real and the unreal; that all things appear as they do only by virtue of the delicate individual physical and mental media through which we are made conscious of them; but the prosaic materialism of the majority condemns as madness the flashes of super-sight which penetrate the common veil of obvious empiricism.
