Russell Kirk developed six "canons" of conservatism, which Gerald J. Russello described as follows:
Kirk said that Christianity and Western Civilization are "unimaginable apart from one another" and that "all culture arises out of religion. When religious faith decays, culture must decline, though often seeming to flourish for a space after the religion which has nourished it has sunk into disbelief."
In later works, Kirk expanded this list into his "Ten Principles of Conservatism" which are as follows:
The idea that a common Judeo-Christian ethics or Judeo-Christian values underpins American politics, law and morals has been part of the "American civil religion" since the 1940s. In recent years, the phrase has been associated with political conservatives, but the concept—though not always the exact phrase—has frequently featured in the rhetoric of leaders across the political spectrum, including that of Franklin D. Roosevelt and Lyndon B. Johnson.
