“If it be of the highest importance to man, as an individual, that his religion should be true, the case of society is not the same. Society has no future life to hope for or to fear; and provided the citizens profess a religion, the peculiar tenets of that religion are of very little importance to its interests.”

Wording in Ideas and Opinions: The Jewish scriptures admirably illustrate the development from the religion of fear to moral religion, a development continued in the New Testament. The religions of all civilized peoples, especially the peoples of the Orient, are primarily moral religions. The development from a religion of fear to moral religion is a great step in peoples' lives. And yet, that primitive religions are based entirely on fear and the religions of civilized peoples purely on morality is a prejudice against which we must be on our guard. The truth is that all religions are a varying blend of both types, with this differentiation: that on the higher levels of social life the religion of morality predominates.

Context: It is easy to follow in the sacred writings of the Jewish people the development of the religion of fear into the moral religion, which is carried further in the New Testament. The religions of all civilized peoples, especially those of the Orient, are principally moral religions. An important advance in the life of a people is the transformation of the religion of fear into the moral religion. But one must avoid the prejudice that regards the religions of primitive peoples as pure fear religions and those of the civilized races as pure moral religions. All are mixed forms, though the moral element predominates in the higher levels of social life.

What is Art? (1897)
Context: Humanity unceasingly strives forward from a lower, more partial and obscure understanding of life to one more general and more lucid. And in this, as in every movement, there are leaders — those who have understood the meaning of life more clearly than others — and of those advanced men there is always one who has in his words and life, manifested this meaning more clearly, accessibly, and strongly than others. This man's expression … with those superstitions, traditions, and ceremonies which usually form around the memory of such a man, is what is called a religion. Religions are the exponents of the highest comprehension of life … within a given age in a given society … a basis for evaluating human sentiments. If feelings bring people nearer to the religion's ideal … they are good, if these estrange them from it, and oppose it, they are bad.

1780s, Memorial and Remonstrance Against Religious Assessments (1785)
Context: We hold it for a fundamental and undeniable truth, “that Religion or the duty which we owe to our Creator and the Manner of discharging it, can be directed only by reason and conviction, not by force or violence.” The Religion then of every man must be left to the conviction and conscience of every man; and it is the right of every man to exercise it as these may dictate. This right is in its nature an unalienable right. It is unalienable; because the opinions of men, depending only on the evidence contemplated by their own minds, cannot follow the dictates of other men: It is unalienable also; because what is here a right towards men, is a duty towards the Creator. It is the duty of every man to render to the Creator such homage, and such only, as he believes to be acceptable to him. This duty is precedent both in order of time and degree of obligation, to the claims of Civil Society. Before any man can be considered as a member of Civil Society, he must be considered as a subject of the Governor of the Universe: And if a member of Civil Society, who enters into any subordinate Association, must always do it with a reservation of his duty to the general authority; much more must every man who becomes a member of any particular Civil Society, do it with a saving of his allegiance to the Universal Sovereign. We maintain therefore that in matters of Religion, no man’s right is abridged by the institution of Civil Society, and that Religion is wholly exempt from its cognizance. True it is, that no other rule exists, by which any question which may divide a Society, can be ultimately determined, but the will of the majority; but it is also true, that the majority may trespass on the rights of the minority.

The New Divinity (1964)
Context: Religion in some form is a universal function of man in society, the organ for dealing with the problems of destiny, the destiny of individual men and women, of societies and nations, and of the human species as a whole. Religions always have some intellectual or ideological framework, whether myth or theological doctrine; some morality or code of behaviour, whether barbaric or ethically rationalized; and some mode of ritualized or symbolic expression, in the form of ceremonial or celebration, collective devotion or thanksgiving, or religious art...

Context: He must be a man of little faith, who would fear to subject his own religion to the same critical tests to which the historian subjects all other religions. We need not surely crave a tender or merciful treatment for that faith which we hold to be the only true one. We should rather challenge it for the severest tests and trials, as the sailor would for the good ship to which he trusts his own life, and the lives of those who are dear to him. In the Science of Religion, we can decline no comparisons, nor claim any immunities for Christianity, as little as the missionary can, when wrestling with the subtle Brahmin, or the fanatical Mussulman, or the plain speaking Zulu.
