Historically, various Jewish sects and movements have been consistent in avoiding or even forbidding [[proselytization]] (religion-to-religion conversion propaganda) to convert [[gentile]]s ([[non-Jews]]). They believe that gentiles do not need to convert to Judaism, due to [[Abrahamic religions]] being already under the [[Seven Laws of Noah]].

[[Chabad Lubavitch]] has a sub-sect that has engaged in an effort to spread [[Noahidism]] ([[Seven Laws of Noah]]) among non-Jews who follow none of the existing [[Abrahamic religions]].

[[Orthodox Judaism outreach]] (''kiruv'') encourages non-practicing [[Jews]] to become more knowledgeable and observant of ''[[halakha]]'' (Jewish law). Outreach is done worldwide, by organizations such as [[Chabad Lubavitch]], [[Aish HaTorah]], [[Ohr Somayach, Jerusalem|Ohr Somayach]], and [[Partners In Torah]].

Members of [[Reform Judaism]] began a program to convert to their brand of Judaism the non-Jewish spouses of its [[Interfaith marriage in Judaism|intermarried]] members and non-Jews who have an interest in Reform Judaism. Their rationale is that so many Jews were lost during [[the Holocaust]] that newcomers must be sought out and welcomed.<ref>{{Citation |title=The Catholic Reform, Jews, and Judaism in Sixteenth-Century Germany |date=2006-01-01 |work=Jews, Judaism, and the Reformation in Sixteenth-Century Germany |pages=249–268 |publisher=BRILL |doi=10.1163/9789047408857_014 |isbn=978-90-474-0885-7 |s2cid=244752108 |last1=Bireley |first1=Robert }}</ref> This approach has been rejected by both [[Orthodox Judaism]] and [[Conservative Judaism]]<ref>[[Missionary#cite note-39]]</ref> as unrealistic and posing a danger on the entire [[Jewish faith]].
