Many jews are literally Satanists, and still consider themselves Jewish so long as they have the bloodline and follow the same rituals: >>Furthermore, religious Jews apparently pray to Satan almost as readily as they pray to God, and depending upon the various rabbinical schools, the particular rituals and sacrifices they practice may be aimed at enlisting the support of the one or the other. Once again, so long as the rituals are properly followed, the Satan-worshippers and the God-worshippers get along perfectly well and consider each other equally pious Jews, merely of a slightly different tradition. One point that Shahak repeatedly emphasizes is that in traditional Judaism the nature of the ritual itself is absolutely uppermost, while the interpretation of the ritual is rather secondary. https://www.unz.com/runz/american-pravda-oddities-of-the-jewish-religion/ Note that Ron Unz is (was?) jewish and he's quoting Israel Shahak.
