"RELIGIONS BECOME INSTITUTIONS when the myths and rituals that once shaped their sacred histories are transformed into authoritative models of orthodoxy (the correct interpretation of myths) and orthopraxy (the correct interpretation of rituals), though one is often emphasized over the other. Christianity may be the supreme example of an "orthodoxic" religion; it is principally one's beliefs--expressed through creed--that make one a faithful Christian. On the opposite end of the spectrum is Judaism, a quintessentially "orthopraxic" religion, where it is principally one's actions--expressed through the Law--that make one an observant Jew. It is not that beliefs are irrelevant in Judaism, or actions unimportant in Christianity. Rather, it is that of the two religions, Judaism places far greater emphasis on orthopraxic behavior than does Christianity."
