👉 "Blue Cult" in the Bible refers to a group of Jews who, upon being converted to Judaism, took on the identity of pagans. This sect, often associated with the Sages, practiced polytheistic religions (i.e., believing in more than one deity) and rejected traditional Jewish practices such as circumcision and the Tannaitic method of interpreting halakha. The term "Blue Cult" became synonymous with these practices, leading to a shift from a strictly observant Jewish community to one that embraced paganism and idolatry.
