KS: "What if you had an organization, like a religion, which said nothing about God or what his name was, but simply how men should live, what should be important in our lives, what is right and what is wrong."

- Sounds like Humanism to me:

Which says a lot about those things, e.g. -

"Thus it is not humanist values that are parasitic on religious ones, but the reverse. True human values are rooted in our need to live fulfilling lives and to share them with others. These values are to be found at all periods of history and in all parts of the world. Unsurprisingly, they are also found in all the great world religions, but there they are always combined and overlaid with other values which are either absurd and trivial (such as insisting that everybody rests from work on the same day of the week or eats only certain kinds of meat) or actively pernicious (such as persecuting gays or stoning adulterers). The core, rational values are humanist ones."
