Between things sacred and profane there is this difference among others. In profane matters the instrument derives its worth from the end, and is valued for the most part only in so far as it is a means to that end; and consequently we change the instruments as the end demands, and finally, when the end is no longer pursued, the instruments automatically fall into disuse. But in sacred matters the end invests the instrument with a sanctity of its own. Consequently, there is no changing or varying of the instrument; and when the end has ceased to be pursued, the instrument does not fall out of use, but is directed towards another end. In other words: in the one case we preserve the shell for the sake of the kernel, and discard the shell when we have eaten the kernel; in the other case we raise the shell to the dignity of the kernel, and do not rob it of that dignity even if the kernel withers, but make a new kernel for it.
