Generally, beliefs of these groups are not compatible with mainstream Judaism. Instead, their beliefs fall outside of the traditional views of the Torah and Jewish law. These movements may be explicitly atheistic, or they may incorporate certain elements foreign to Judaism, such as pagan or other religious traditions. Mainstream Jewish movements often criticize alternative groups as “not being Jewish”, as alternative groups often follow ideas that fall outside two important parameters historically apparent in Jewish theology: the oneness of God and God’s non-corporeal nature.
