Terminology

A male convert to Rabbinical Judaism is referred to by the biblical word ger and a female convert is a giyoret. The word is related to the term "proselyte
Proselyte
The biblical term "Proselyte", derives from the Koine Greek προσήλυτος/proselytos, as used in the Septuagint for "stranger", i.e. a "newcomer to Israel"; a "sojourner in the land", and in the New Testament for a convert to Judaism from Paganism...

As Jews were not converts in Egypt, but rather strangers, the verse is an indication that the meaning of ger is "stranger". There is no place in the Hebrew Bible where the term "ger" is clearly used to refer to a convert to Judaism. The closest thing in the Hebrew Bible to a conversion process is the circumcision

, and religious gerut is also discouraged. In the past, Rabbis often rejected potential converts three times, and if they remained adamant in their desire to convert, they would then allow them to begin the process. This practice has been justified on several grounds, including:
  • The laws Jews require of themselves are more stringent than they consider to be required of other nations; a person who would be considered derelict of religious duties under Jewish law could easily be, without change in action, an exceedingly righteous gentile.
  • Jews have suffered regular and often severe persecution throughout the ages; a proselyte is exposing himself to potentially mortal danger.
  • In the Book of Ruth, Naomi tried to get Ruth to go back to her own people three times before Ruth became a part of the Hebrew people.


However, a rabbi convinced of the prospective convert's sincerity may allow him or her to follow the process of conversion. This requires the person to appear before an established three-judge Jewish religious court known as a beth din

 for conversions are different. The denomination states that "people considering conversion are expected to study Jewish theology, rituals, history, culture and customs, and to begin incorporating Jewish practices into their lives. The length and format of the course of study will vary from rabbi to rabbi and community to community, though most now require a course in basic Judaism and individual study with a rabbi, as well as attendance at services and participation in home practice and synagogue life."

Although an infant conversion might be accepted in some circumstances (such as in the case of adopted children or children whose parents convert), children who convert would typically be asked if they want to remain Jewish after reaching religious adulthood – which is 12 years of age for a girl and 13 for a boy. This standard is applied by Orthodox and Conservative Judaism, which accept halakha as binding.

At a ceremony in their Northern California synagogue, ten adults and four minors swore fealty to Judaism after completing a year of study. This conversion comes 15 years after the Karaite Council of Sages reversed its centuries-old ban on accepting converts.

However, later, "a certain other Jew that came out of Galilee, whose name was Eleazar", who was well versed in the Law, convinced him that he should, on the grounds that it was one thing to read the Law and another thing to practice it, and so he did. Once Helen and Ananias found out, they were struck by great fear of the possible consequences, but as Josephus put it, God looked after Izates. As his reign was peaceful and blessed, Helen visited the Jerusalem Temple to thank God, and since there was a terrible famine at the time, she brought lots of food and aid to the people of Jerusalem.

Modern practice

The requirements for conversions vary somewhat within the different branches of Judaism, so whether or not a conversion is recognized by another denomination is often an issue wrought with religious politics. The Orthodox rejection of non-Orthodox conversions is derived less from qualms with the conversion process itself, since Conservative and even some Reform conversions are ostensibly very similar to Orthodox conversions with respect to duration and content, but rather the belief that a non-Orthodox Rabbi is not qualified to oversee and perform a conversion.

In general, immersion in the mikveh is an important part of conversion. If the person who is converting is male, circumcision
Circumcision
Male circumcision is the surgical removal of some or all of the foreskin from the penis. The word "circumcision" comes from Latin and ....

 is a part of the conversion process as well. If the male who is converting has already been circumcised, then a ritual removal of a single drop of blood will take place.

Maturity

Someone who was converted to Judaism as a child has an option of rejecting this after reaching the age of maturity, which in Judaism is age twelve for girls or thirteen for boys.

, the official body of American Reform rabbis, formally resolved to permit the admission of converts "without any initiatory rite, ceremony, or observance whatever." (CCAR Yearbook 3 (1893), 73–95; American Reform Responsa (ARR), no. 68, at 236–237.)

Although this resolution has often been examined critically by many Reform rabbis, the resolution still remains the official policy of American Reform Judaism (CCAR Responsa "Circumcision for an Eight-Year-Old Convert" 5756.13 and Solomon Freehof
Solomon Freehof

, Reform Responsa for Our Time, no. 15.) Thus, American Reform Judaism does not require ritual immersion in a mikveh, circumcision, or acceptance of mitzvot as normative. Appearance before a Bet Din is recommended, but is not considered necessary. Converts are asked to commit to religious standards set by the local Reform community.

Interdenominational views

In response to the tremendous variations that exist within the Reform community, the Conservative Jewish movement attempted to set a nuanced approach. The Conservative Committee on Jewish Law and Standards

The Committee on Jewish Law and Standards is the central authority on halakha within Conservative Judaism; it is one of the most active and widely known committees on the Conservative movement's Rabbinical Assembly. Within the movement it is known as the CJLS...

 has issued a legal opinion stating that Reform conversions may be accepted as valid only when they include the minimal Conservative halachic requirements of milah and t'vilah, appearance before a Conservative Bet Din, and a course of Conservative study. (Proceedings of Committee on Jewish Law and Standards: 1980–1985, pp. 77–101.)

In general, branches of Orthodox Judaism consider non-Orthodox conversions either inadequate or of questionable halachic compliance, and such conversions are therefore not accepted by these branches of Judaism. Conversely, both Conservative and Reform Judaism accept the stringent Orthodox conversion process as being valid. Since 2008, Haredi Orthodox religious courts in Israel have been rejecting conversions from other Orthodox rabbis, in addition to Reform and Conservative conversions, as not being stringent enough.

Intra-Orthodox views

Orthodox Jewish groups are not unified, and different orthodox communities may hold themselves as more strictly correct in observance than others, or consider others' religious observances of inadequate strictness and validity. As such, Orthodox rabbis often will not automatically accept each other's authority, which has led to a some reluctance in certain Orthodox communities to prepare and perform conversions.

, and a number of other Orthodox rabbis. Many critiques are aimed at Modern Orthodox Jews, who they label as "so-called Orthodox". Orthodox rabbis who cooperate in any way with non-Orthodox Jews are labeled as "orthodox", in quotes with a lower case "o", while Haredi rabbis are called Orthodox rabbis, with no quotes and no lower case letters.

. They tentatively floated a compromise: the RCA would draft a joint list of qualified beth dins authorized to perform conversions in the future, and the Chief Rabbinate of Israel would review the list; all conversions accepted by the RCA in the past and for a short period in the future will be accepted. As of May 2007, this agreement has not been accepted by Rabbi Amar. Rabbi Amar has demanded that RCA rabbis on American Beit Din be approved by the Israeli rabbinate. Traditionally, Orthodox communal rabbis have refrained from implementing tests on colleagues from other regions. Rabbi Amar's demand to vet RCA rabbis marks an evolution in diaspora and Israeli rabbinate relations. Rabbi Amar has also demanded more Haredi representation on Israel's conversion courts. Meanwhile, within Israel, the status of converts is becoming more confused. Recently, an Israeli rabbi in Ashdod retroactively annulled an Orthodox conversion performed by another rabbi whom he regards as not complying with the halakha.

Under Immigrant Absorption Minister Ze'ev Boim's plan, power would be distributed more widely than at present. According to Erez Halfon, director general of the Absorption Ministry, the current system's "rabbinical courts are intimidating converts as well as rabbis by setting unreasonable requirements." The reform proposes unifying institutions that deal with conversion under one administrative umbrella, and doubling the number of rabbinical judges who review conversions.

Some Sephardic Orthodox rabbis, particularly those of Judeo-Spanish descent, take a more liberal view of conversion than the majority opinion. For instance, the first Sephardic Chief Rabbi of Israel, Benzion Uziel, held that conversions should be accepted, if not strongly recommended, in the case of an intermarried couple who will continue to live as man and wife regardless of whether the non-Jewish spouse converts. Rabbi Uziel reasoned that it was preferable to convert the non-Jewish partner, regardless of the partner's reasoning for converting, than to permit the Jewish partner to continue transgressing by living with a non-Jew in a spousal relationship. Today, advocates for Rabbi Uziel's opinion include Rabbi Marc D. Angel

These converts, ostensibly now unable to marry, be buried in Jewish ceremonies, or have recognized Jewish children, may have to re-convert under Haredi auspices. This controversial ruling is unprecedented in Jewish history.

. One is made up of a Bet Din (Jewish Court) of congregational member rabbis from the Rabbinical Council of America, Montreal region (RCA). This program provides a way to convert according to the rigorous rules of Halachah while making the process more “user friendly” for non-Jewish individuals seeking a more “hands-on” or “modern Orthodox” approach. The second program is supervised by the Jewish Community Council of Montreal, the Vaad Hair.

All conversion candidates – who could include singles, non-Jewish couples and adoption cases – must have a sponsoring rabbi and undergo a rigorous screening process. Conversions stemming from both programs are recognized in Israel and around the world.

; their goal was to create a joint Orthodox-Conservative national beth din for all Jews in America. It would create communal standards of marriage and divorce. It was to be modeled after the Israeli Chief Rabbinate, where all the judges would have been Orthodox, while it would have been accepted by the larger Conservative movement as legitimate. Conservative rabbis in the Rabbinical Assembly created a Joint Conference on Jewish Law, devoting a year to this effort.

For a number of reasons, the project did not succeed. According to Orthodox Rabbi Bernstein, the major reason for its failure was the Orthodox rabbis insisted that the Conservative Rabbinical Assembly expel Conservative rabbis for actions they took before this new beth din was formed, and the RA refused to do so. According to Orthodox Rabbi Emanuel Rackman, former president of the RCA, the major reason for its failure was pressure from haredi Orthodox rabbis, who held that any cooperation between Orthodoxy and Conservatism was forbidden. In 1956, Rabbi Harry Halpern

, of the Joint Conference wrote a report on the demise of this beth din. He writes that negotiations between the Orthodox and Conservative were completed and agreed upon, but then a new requirement was demanded by the RCA: The RA must "impose severe sanctions" upon Conservative rabbis for actions they took before this new beth din was formed. Halpern writes that the RA "could not assent to rigorously disciplining our members at the behest of an outside group." He goes on to write that although subsequent efforts were made to cooperate with the Orthodox, a letter from eleven Rosh Yeshivas was circulated declaring that Orthodox rabbis are forbidden to cooperate with Conservative rabbis.

; these synagogues were called traditional Judaism. Over a five year period they performed some 750 conversions to Judaism. However, in 1983 the joint Beth Din was dissolved, due to the unilateral American Reform Jewish decision to change the definition of Jewishness.
The move was precipitated by the resolution on patrilineality adopted that year by the Central Conference of American Rabbis. This decision to redefine Jewish identity, as well as the designation of Denver as a pilot community for a new Reform out reach effort to recruit converts, convinced the Traditional and Conservative rabbis that they could no longer participate in the joint board ...the national decision of the Reform rabbinate placed the Traditional and Conservative rabbis in an untenable position. They could not cooperate in a conversion program with rabbis who held so different a conception of Jewish identity. And furthermore, they could not supervise conversions that would occur with increasing frequency due to a Reform outreach effort that was inconsistent with their own understanding of how to relate to potential proselytes.


The end of this program was welcomed by Haredi Orthodox groups, who saw the program as illegitimate. Further, Haredi groups attempted to prevent non-Orthodox rabbis from following the traditional requirements of converts using a mikvah. In the Haredi view, it is better to have no conversion at all than a non-Orthodox conversion, as all non-Orthodox conversions are not true conversions at all according to them.

1980s: proposed Israeli joint beth din

 spearheaded an effort to create a solution to the "Who is a Jew?" issue.

A plan was developed by Israeli Cabinet Secretary Elyakim Rubenstein, who negotiated secretly for many months with rabbis from Conservative, Reform and Orthodox Judaism, including faculty at Yeshiva University, with Lamm as Rosh Yeshiva. They were planning to create a joint panel that interviewed people who were converting to Judaism and considering making aliyah (moving to the State of Israel), and would refer them to a beth din that would convert the candidate following traditional halakha. All negotiating parties came to agreement:
  1. Conversions must be carried out according to halakha
  2. the beth din (rabbinic court) overseeing the conversion would be Orthodox, perhaps appointed by the Chief Rabbinate of Israel, and
  3. there would be three-way dialogue throughout the process.


Many Reform rabbis took offense at the notion that the beth din must be strictly halakhic and Orthodox, but they acquiesced. However, when word about this project became public, a number of leading haredi rabbis issued a statement denouncing the project, condemning it as a "travesty of halakha". Rabbi Moshe Sherer, Chairman of Agudath Israel World Organization, stated that "Yes we played a role in putting an end to that farce, and I'm proud we did." Norman Lamm condemned this interference by Sherer, stating that this was "the most damaging thing that he [Sherer] ever did in his forty year career."

Rabbi Lamm wanted this to be only the beginning of a solution to Jewish disunity. He stated that had this unified conversion plan not been destroyed, he wanted to extend this program to the area of halakhic Jewish divorces, thus ending the problem of mamzerut.

1997: Neeman Commission proposal

In 1997 the issue of "Who is a Jew?" again arose in the State of Israel, and Orthodox leaders such as Rabbi Norman Lamm

 publicly backed the Neeman commission, a group of Orthodox, Conservative and Reform rabbis working to develop joint programs for conversion to Judaism. In 1997 Lamm gave a speech at the World Council of Orthodox Leadership, in Glen Springs, N.Y., urging Orthodox Jews to support this effort.
Lamm told his listeners that they should value and encourage the efforts of non-Orthodox leaders to more seriously integrate traditional Jewish practices into the lives of their followers. They should welcome the creation of Reform and Conservative day schools and not see them as a threat to their own, Lamm said. In many communities, Orthodox day schools, or Orthodox-oriented community day schools, have large numbers of students from non-Orthodox families. The liberal movements should be appreciated and encouraged because they are doing something Jewish, even if it is not the way that Orthodox Jews would like them to, he said. "What they are doing is something, and something is better than nothing," he said in his speech. "I'm very openly attacking the notion that we sometimes find in the Orthodox community that `being a goy is better'" than being a non-Orthodox Jew, he said in an interview.

2000s: Conversion Annulments and Confusion

A current situation of confusion and instability in Jewish identity in Israel was made worse when Haredi Rabbi Avraham Sherman of Israel's supreme religious court called into question the validity of over 40,000 Jewish conversions when he upheld a ruling by the Ashdod Rabbinical Court to retroactively annul the conversion of a woman who came before them because in their eyes she failed to observe Jewish law (an orthodox lifestyle)..
This crisis deepened, when Israel's Rabbinate called into question the validity of soldiers who had undergone conversion in the army, meaning a soldier killed in action could not be buried according to Jewish law.
In 2010, the rabbinate created a further distrust in the conversion process when it began refusing to recognize orthodox converts from the United States as Jewish.
It is important to note, that according to the present judgements of Israel's Supreme Rabbinical Court, the former President of the State of Israel, Ezer Weizmann would not be seen as Jewish, as his mother (married to Israel's first President and Zionist pioneer Chaim Weizmann

Consequences

Once undergone, a religious conversion to Judaism is irreversible (from a Jewish perspective), unless there are convincing grounds to believe that the convert was insincere or deceitful during the conversion process. In such cases, a beth din may determine that the conversion was void.

Relations between Jews and proselytes

Judaism today, unlike Christianity and Islam, is not normally an openly proselytizing religion: unlike certain sects of those religions, it teaches that the righteous of all nations have a place in the afterlife.There is a requirement in Jewish law to ensure the sincerity of a potential convert. This is taken very seriously, and when played out against the background of the foregoing considerations, most authorities are very careful about it. Essentially, they want to be sure that the convert knows what he is getting into, and that he is doing it for sincerely religious reasons. However, while conversion for the sake of love for Judaism is considered the best motivation, a conversion for the sake of preventing intermarriage is gaining acceptance, also.
There is a tradition that a prospective convert should be turned away three times as a test of sincerity, though most rabbis no longer follow the tradition. Neither the Rabbinical Council of America

Halakhic considerations

Halakha forbids the mistreatment of the convert, including reminding a convert that he or she was once not a Jew. and hence little distinction is made in Judaism between those who are born Jewish and those who are Jewish as a result of conversion. However, despite Halakha protecting the rights of converts, some Jewish communities have been accused of treating converts as second class Jews. For example, many communities of Syrian Jews

, a convert to Judaism.
In Orthodox and Conservative communities which maintain tribal distinctions, converts become Yisraelim (Israelites), ordinary Jews with no tribal or inter-Jewish distinctions. Converts typically follow the customs of their congregations. So a convert who prays at a Sephardi synagogue would follow Sephardi customs and learn Sephardi Hebrew.

A convert chooses his or her own Hebrew first name upon conversion but is traditionally known as the son or daughter of Abraham and Sarah, the first patriarch and matriarch in the Torah, often with the additional qualifier of "Avinu" (our father) and "Imenu" (our mother). Hence, a convert named Akiva would be known, for ritual purposes in a synagogue, as "Akiva ben Avraham Avinu"; in cases where the mother's name is used, such as for the prayer for recovery from an illness, he would be known as "Akiva ben Sarah Imenu".

Talmudic opinions on converts are numerous; some positive, some negative. A famous quote from the Talmud, labels the convert "Hard on Israel as a blight." Many interpretations explain this quote as meaning converts can be unobservant and leading Jews to be unobservant, or converts can be so observant that born Jews feel ashamed.

Jews by choice

The term "Jew by choice" is often used to describe someone who converted to Judaism, and is often contrasted with such terms as "Jew by birth" ("Jew by chance").
