In today's world there is racism, discrimination and hatred towards ethnic groups, religions and cultures. A well-known organization is Jews for Jesus. They are simply spreading their thoughts about their beliefs. However, in doing so, they slap the Jews who have turned their backs on their brothers. If they are truly Jews, then why do they believe that Jesus was the Messiah? This essay will show what Jews for Jesus believes, how Jews for Judaism contradicts their opinion, and both organizations' methods for gaining members and spreading their beliefs. Jews for Jesus is an evangelical Christian organization based in San Francisco, California. This means that they are an organization that travels and spreads beliefs. Jews for Jesus are spreading the belief that Jesus is the Messiah and God. In doing so, they also promote awareness of Jewish and Christian heritage. The ironic thing is that Jews for Jesus claim that their followers "live according to their Jewishness" and identify as Jews. However, a large number of Jews, groups, organizations and many others reject this and consider the group to be Christian. On "www.forjewsforjesus.com" - a Jews for Jesus website - the question is asked: "Can you explain how one can be Jewish and Christian at the same time? It seems like a contradiction in terms." The site responds by saying, "The definition of who is Jewish is hotly debated within the Jewish community. Some want to define 'Jewish' as ​​cultural, others as religious, and still others as a matter of kinship." they believe that Jewishness is a birthright and inherited from parents. The people in the organization do not belong to a culture; they have different cultural expressions such as Ashkenazi, Sephardic, Russian, Ethiopian, etc. Missionaries consider themselves to have more than one religion. Although Judaism may be the traditional religion for many Jews, Jews are still considered Jewish even if they may be atheists or even if they have other beliefs, such as Christianity. They claim that people "have no right to deny their Jewishness. We are Jews by birth and that cannot change." According to Jews for Jesus, you can be Jewish and Christian at the same time. “Jews” refers to who they are. “Christian” is a designation for which they follow.
