“No man's religion ever survives his morals.”

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.

Context: The analysis of the moral man through his actions, and of the intellectual man through his productions, seems to me calculated to form one of the most interesting parts of the sciences of observation, applied to anthropology.
