“If by religion, we are understand sectarian dogmas, in which no two of them agree, then your exclamation on that hypothesis is just, "that this would be the best of all possible worlds, if there were no religion in it." But if the moral precepts, innate in man, and made a part of his physical constitution, as necessary for a social being, if the sublime doctrines of philanthropism and deism taught us by Jesus of Nazareth, in which all agree, constitute true religion, then, without it, this would be, as you again say, "something not fit to be named, even indeed, a hell."”

As quoted in Benjamin Franklin: An Exploration of a Life of Science and Service (1938) by Carl Van Doren,<!-- New York: The Viking Press --> p. 777.
Variation: "The moral and religious system which Jesus Christ transmitted to us is the best the world has ever seen, or can see.", as quoted in John Wallis (1856), The British Millennial Harbinger https://books.google.es/books?id=jfgDAAAAQAAJ&pg=PA428&dq=franklin, p. 428.
Context: As to Jesus of Nazareth, my Opinion of whom you particularly desire, I think the System of Morals and his Religion, as he left them to us, the best the world ever saw or is likely to see; but I apprehend it has received various corrupt changes, and I have, with most of the present Dissenters in England, some Doubts as to his divinity; tho' it is a question I do not dogmatize upon, having never studied it, and I think it needless to busy myself with it now, when I expect soon an Opportunity of knowing the Truth with less Trouble.

The Uttarpara Address (1909)
Context: That which we call the Hindu religion is really the eternal religion, because it is the universal religion which embraces all others. If a religion is not universal, it cannot be eternal. A narrow religion, a sectarian religion, an exclusive religion can live only for a limited time and a limited purpose. This is the one religion that can triumph over materialism by including and anticipating the discoveries of science and the speculations of philosophy. It is the one religion which impresses on mankind the closeness of God to us and embraces in its compass all the possible means by which man can approach God. It is the one religion which insists every moment on the truth which all religions acknowledge that He is in all men and all things and that in Him we move and have our being. It is the one religion which enables us not only to understand and believe this truth but to realise it with every part of our being. It is the one religion which shows the world what the world is, that it is the Lila of Vasudeva. It is the one religion which shows us how we can best play our part in that Lila, its subtlest laws and its noblest rules. It is the one religion which does not separate life in any smallest detail from religion, which knows what immortality is and has utterly removed from us the reality of death.

Context: I cannot claim to have had any direct personal divine inspiration. Yet coping with multitudinous problem-solving efforts and observing the world in which I live evokes an openness to a mystery of being that I cannot deny. Critical reflection leads me to believe than an awareness of such mysteries is a necessity in the constitution of order in democratic societies. If religion is a necessity in the conceptualization of paradigmatically diverse formulations, religion might be viewed as a necessary element in a system of knowledge pertaining to the consitution of order. We do, however, face the problem of those system of order that were constituted under circumstances of explicitly rejecting religion as a necessary feature in their constitution. We have the potential, then, of those who reject religion becoming the prophets of new secular religions. What we call "ideologies" may be the source of that most profound pathologies in human personal and social disorders.
