“What has been called Christianity has been a disturber of the public peace in all countries and at all times. Nothing has so alienated nations, nothing has so destroyed the natural justice of mankind, as what has been known as religion. The idea that all men must worship the same God, believe the same dogmas, has for thousands of years plucked with bloody hands the flower of pity from the human heart.”

The Grounds and Reasons of Christian Regeneration (1739)
Context: Some People have an Idea, or Notion of the Christian Religion, as if God was thereby declared so full of Wrath against fallen Man, that nothing but the Blood of his only begotten Son could satisfy his Vengeance.
Nay, some have gone such Lengths of Wickedness, as to assert that God had by immutable Decrees reprobated, and rejected a great Part of the Race of Adam, to an inevitable Damnation, to show forth and magnify the Glory of his Justice.
But these are miserable Mistakers of the Divine Nature, and miserable Reproachers of his great Love, and Goodness in the Christian Dispensation.
For God is Love, yea, all Love, and so all Love, that nothing but Love can come from him; and the Christian Religion is nothing else but an open, full Manifestation of the universal Love towards all Mankind.
As the Light of the Sun has only one common Nature towards all Objects that can receive it, so God has only one common Nature of Goodness towards all created Nature, breaking forth in infinite Flames of Love, upon every Part of the Creation, and calling everything to the highest Happiness it is capable of.

From an essay in A Defense of Indian Culture, as quoted in The Vision of India (1949) by Sisirkumar Mitra
Context: Spirituality is the master key of the Indian mind. It is this dominant inclination of India which gives character to all the expressions of her culture. In fact, they have grown out of her inborn spiritual tendency of which her religion is a natural out flowering. The Indian mind has always realized that the Supreme is the Infinite and perceived that to the soul in Nature the Infinite must always present itself in an infinite variety of aspects. The aggressive and quite illogical idea of a single religion for all mankind, a religion universal by the very force of its narrowness, one set of dogmas, one cult, one system of ceremonies, one ecclesiastical ordinance, one array of prohibitions and injunctions which all minds must accept on peril of persecution by men and spiritual rejection or eternal punishment by God, that grotesque creation of human unreason which has been the parent of so much intolerance, cruelty and obscurantism and aggressive fanaticism, has never been able to take firm hold of the Indian mentality.

Wie steht es bei dem Kreisen der sogenannten Elektronen um ihren zentralen Kern? Was ist hier wirklich unmittelbar wahrgenommen worden? Nichts von den bewegten Teilchen; was vielmehr beobachtet wurde, sind Erscheinungen, welche auf den ersten Blick mit der Bewegung von Körpern gar nichts zu tun haben. Alles übrige, was zum Atommodell geführt, ist eine lange Kette von Schlüssen.
In an address to the Viennese Chemisch-Physikalische Gesellschaft http://www.cpg.univie.ac.at/, April 26, 1932, as quoted by [Joseph Braunbeck, Der andere Physiker: das Leben von Felix Ehrenhaft, Leykam Buchverlagsgesellschaft, 2003, 3701174709, 51]

Religion and Philosophy in Germany, A fragment https://archive.org/stream/religionandphilo011616mbp#page/n5/mode/2up. p. 25
Context: I believe in progress; I believe that happiness is the goal of humanity, and I cherish a higher idea of the Divine Being than those pious folk who suppose that man was created only to suffer. Even here on earth I would strive, through the blessings of free political and industrial institutions, to bring about that reign of felicity which, in the opinion of the pious, is to be postponed till heaven is reached after the day of Judgment. The one expectation is perhaps as vain as the other; there may be no resurrection of humanity either in a political or in a religious sense. Mankind, it may be, is doomed to eternal misery; the nations are perhaps under a perpetual curse, condemned to be trodden under foot by despots, to be made the instruments of their accomplices and the laughing-stocks of their menials. Yet, though all this be the case, it will be the duty even of those who regard Christianity as an error still to uphold it; and men must journey barefoot through Europe, wearing monks' cowls, preaching the doctrine of renunciation and the vanity of all earthly possessions, holding up before the gaze of a scourged and despised humanity the consoling Cross, and promising, after death, all the glories of heaven.
The duration of religions has always been dependent on human need for them. Christianity has been a blessing for suffering humanity during eighteen centuries; it has been providential, divine, holy. All that it has done in the interest of civilisation, curbing the strong and strengthening the weak, binding together the nations through a common sympathy and a common tongue, and all else that its apologists have urged in its praise all this is as nothing compared with that great consolation it has bestowed on man. Eternal praise is due to the symbol of that suffering God, the Saviour with the crown of thorns, the crucified Christ, whose blood was as a healing balm that flowed into the wounds of humanity. The poet especially must acknowledge with reverence the terrible sublimity of this symbol.
