Encyclopedia
Rabbi Leo Jung was one of the major architects of American Orthodox Judaism
.
then was elected Rabbi of Uherský Brod
in 1890. Rabbi Meir Tzvi Jung believed in the Torah im Derekh Eretz (Torah combined with worldly activity) philosophy of Rabbi Samson Raphael Hirsch
. Later he moved to London. Rabbi Leo Jung's father founded schools in Uherský Brod, Cracow and London
, where both religious and secular learning took place. In London, Rabbi Meir Tzvi Jung was a leader in Agudat Israel
, and the Sinai Movement. The Sinai Movement was a movement in which young men would meet for the purpose of studying Talmud and socializing. At his death, in June 1921, Rabbi Jung was the Chief Minister of the Federation of Synagogues in England, an appointment he had held since 1912.
In 1916, Rabbi Leo Jung became the director general of the Sinai League of which his father was founder and president. Rabbi Meir Tsevi founded the journal, "The Sinaist", based on the Torah im derekh eretz philosophy. Leo Jung became the editor of this bi-monthly journal, which he claimed expressed his father’s philosophy, "study is great, for it leads to (right) action".
Rabbi Jung, like his father, received a secular and Talmudic education. He attended Cambridge University and he received his doctorate from the University of London
. In 1910 he attended the Yeshiva
of Eperies and in 1911 he went to study in Galanta
, Hungary. He also attended the Hildesheimer Rabbinical Seminary
in Berlin. Jung claimed that he received three rabbinic ordinations, from Rabbi Mordechai Zevi Schwartz, Rabbi Abraham Isaac Kook
and Rabbi David Zvi Hoffmann of Berlin. He regarded his semikhah from David Hoffman as, "his last and most cherished semikhah"
Rabbi Jung hired as principal of the newly founded afternoon school Dr. Joseph Kaminetsky
, who became later became executive director of Manhattan Day School
, which evolved from The Jewish Center Day School. Dr. Kaminetsky later became the director of the Torah Umesorah school system.
Since Orthodoxy was not well represented in the Jewish-American publication world, Jung's Jewish Library Series and his other works played an important role in creating books for and about Orthodox Judaism. The multi-volumed series helped promote traditional rabbinic biography and literature among the American public.
In 1926, Rabbi Jung as head of the editorial board of the Jewish Forum recommended that all Jewish organizations have Sabbath observance
as a fundamental purpose. The UOJCA
instituted a Sabbath Committee, which included Rabbi Jung. The committee's goal was to educate, to rally loyalty to the Sabbath and facilitate employment opportunities for Sabbath observers.
Rabbi Jung was vice president of the UOJCA
, from 1926 to 1934. In 1926 Jung organized The Rabbinic Council of the UOJCA and was its president for the following eight years. The Rabbinic Council was to assume the rabbinic functions of the Union, including kashrut supervision; the "OU" became its organizational symbol and trademark. developed the kashrut certificate department As vice president of the UOJCA and organizer of its Rabbinic Council, Jung and others began a crusade to fight the corrupt "kashrut jungle" and replace it with a reliable system under the OU imprint.
He built new mikvehs
, "hygienically and aesthetically on the heights of Judaism". He was responsible for some fifteen aesthetic and modern mikvehs in America. He stated in Rhythm of Life, p. 44
Rabbi Jung was involved in raising standards by actively creating commissions to improve observance of most aspects of Jewish ritual life including circumcision, conversion
, kashrus, shabbos, burial, and mikveh.
As chairman of the American Beth Jacob Committee, Rabbi Leo Jung was involved with the promulgating in America of the tragic story of story of the 93 Beis Yaakov "Martyrs". He instituted Kaddish at the Jewish Center for them. Some consider the story apocyphal.
As late as 1942, Rabbi Jung was raising money and addressing audiences on the significance of Agudat Israel; however he quit his membership after the State of Israel was founded when Agudat Israel would not co-operate with the Israeli government, even on non-religious affairs.
Rabbi Jung was sent to Palestine by the American Fund for Palestine Institutions, which supported eighty-six institutions from opera to Beth Jacob, from Habimah (the theatre) to Yeshiva Institutions. Jung also went as chair of the JDC Cultural Committee helping in supporting Yeshivas.
As chair of the religious board of JDC, he saw to it that religious needs were met for Jews in other lands. He went to North Africa in February 1955 to inspect JDC’s educational and religious institutions in Tangiers, Morocco, Algiers and Tunis. He also came to the aid of Jews in Iran.
His Israel affiliation was with Poale Agudat Israel
, which was called "a fortress of religious Jewry" by some but fiercely opposed by the leading Haredi rabbis of the time. Jung worked for Kibbutz Chofetz Chaim and for its children’s village.
He was involved in the resettlement of Lubavitch to New York and specifically in helping Rabbi Yosef Yitzchok Schneersohn.
In America, he fought for proper employment laws.
Rabbi Jung advocated civil rights, avoiding nuclear disaster, and the fighting of the immorality of communism. His speeches from the 1950s are against segregation, against atomic energy, in favor of the United Nations wanting to bring world peace, racial and economic justice in America. His message is the message of mainline religion. Light will triumph over darkness, good over evil.
During these years, he was on the Executive Committee of the Rabbi Samson Raphael Hirsch Society, whose goal was to translate works by German Orthodox thinkers into English. These works became the core of the Feldheim publishing house.
Jung’s book, Living Judaism, from 1922–1923, states that he is the rabbi of the Jewish Center, a synagogue for “Jewish Jews.” Jung begins an article, “Modern Trends in American Judaism,” written in 1936, with the motto for “Jewish Jews.”
Leo Jung wrote an essay: “What is Orthodox Judaism” based on lectures from 1927, that may be summarized as follows.
1. We are Torah true. But:
a. Judaism is not fundamentalist, we are against all forms of fundamentalism.
b. Judaism has many voices. All of them accept God, revelation and the law.
c. Judaism is not out of date. Jewish law is forever adapting to the world, through Responsa.
We fully accept the general cultural world around us. The ghetto conditions of Eastern Europe and the lower East Side of NYC make the true vision of Judaism hard to be heard. True Judaism is up to date and cultural, but the lower East Side blinds people to Judaism.
2. Judaism is about mitzvot, which teach the highest ideals of mankind. Mitzvot embraces all life, eating, sexuality, pleasure, song, and work. Through mitzvot, you learn to give up leading a materialistic immigrant life. Judaism teaches a proper family life. Torah and mitzvot are an education, they train a person to be a perfect gentleman. Judaism is about a whole sentiment of the “life of the spirit”, all Torah study is for practical ends.
Rabbi Jung cites the contemporary philosophies of Havelock Ellis
, “The Dance of Life” (1923), Hans Driesch, and Henri Bergson
to prove the vitality of life.
Jung developed a friendship with the Pulitzer Prize
winning author Herman Wouk
in which they corresponded about Orthodoxy. This dialogue culminated in Wouk publishing This is My God: The Jewish Way of Life
in 1959, an introduction to Orthodox Judaism for an American audience.
Rabbi Emanuel Rackman
has pointed out that Jung’s approach to religion is called the psychological approach as this approach analyses religion with “peace of mind” and “happy and noble living” as its end.

Coupled with the inability of the rabbis to discuss this all-important subject and with a lack of informed rebellion among women (who should have refused to get married before the community established decent mikvaoth) the situation prevailed which rendered such hostility on the part of the half informed and uninformed young women more intelligible."

War Years
Rabbi Jung was chairman of the American Beth Jacob Committee, founded to support schools for European Orthodox Jewish girls formed in 1927. Run by Agudas Israel, the movement was founded by Sara Schenirer, with the help of some leading Western European Jews to provide an education for girls.As chairman of the American Beth Jacob Committee, Rabbi Leo Jung was involved with the promulgating in America of the tragic story of story of the 93 Beis Yaakov "Martyrs". He instituted Kaddish at the Jewish Center for them. Some consider the story apocyphal.
As late as 1942, Rabbi Jung was raising money and addressing audiences on the significance of Agudat Israel; however he quit his membership after the State of Israel was founded when Agudat Israel would not co-operate with the Israeli government, even on non-religious affairs.

His Israel affiliation was with Poale Agudat Israel

, which was called "a fortress of religious Jewry" by some but fiercely opposed by the leading Haredi rabbis of the time. Jung worked for Kibbutz Chofetz Chaim and for its children’s village.
He was involved in the resettlement of Lubavitch to New York and specifically in helping Rabbi Yosef Yitzchok Schneersohn.
In America, he fought for proper employment laws.
Later years
In the 1950s his constant themes were reverence, righteousness and rachmanut, which he referred to as the three "R’s" of kedushah (holiness). Reverence for God and man was essential to ensure righteousness or justice, which includes the assurance of our personal worth and of human dignity. Jung wrote:- "The key to Judaism is “kedushah” (holiness), the endeavor to plant heaven on earth through divine values. Religion as such is co-extensive with life, holding us close to God. It may be neither divorced from life, nor divorced from God. The Hebrew term kedushah appears in connection with every aspect of Jewishness, from marriage to business from dietary laws to the laws of mourning… I would fain say of holiness within the Jewish scheme of life that it is composed of three “R’s”: Reverence, Righteousness and for the moment unexplained rachamanut… The crowning quality is Rahamanut for which there is as yet no word in the English language. Rahamanut is usually translated as “mercy” or “compassion” but etymologically it means “mother’s love”—the unselfish dedicated love of a mother for her little one, her passionate desire to spend herself… for the purpose of raising her baby from helpless infancy towards self sufficient maturity."
Rabbi Jung advocated civil rights, avoiding nuclear disaster, and the fighting of the immorality of communism. His speeches from the 1950s are against segregation, against atomic energy, in favor of the United Nations wanting to bring world peace, racial and economic justice in America. His message is the message of mainline religion. Light will triumph over darkness, good over evil.
During these years, he was on the Executive Committee of the Rabbi Samson Raphael Hirsch Society, whose goal was to translate works by German Orthodox thinkers into English. These works became the core of the Feldheim publishing house.
Thought and Definition of Orthodoxy
Rabbi Jung presented a platform of “Torah-true” Judaism; in his view, “Orthodoxy was the only legitimate form of Judaism.”Jung’s book, Living Judaism, from 1922–1923, states that he is the rabbi of the Jewish Center, a synagogue for “Jewish Jews.” Jung begins an article, “Modern Trends in American Judaism,” written in 1936, with the motto for “Jewish Jews.”
Leo Jung wrote an essay: “What is Orthodox Judaism” based on lectures from 1927, that may be summarized as follows.
1. We are Torah true. But:
a. Judaism is not fundamentalist, we are against all forms of fundamentalism.
b. Judaism has many voices. All of them accept God, revelation and the law.
c. Judaism is not out of date. Jewish law is forever adapting to the world, through Responsa.
We fully accept the general cultural world around us. The ghetto conditions of Eastern Europe and the lower East Side of NYC make the true vision of Judaism hard to be heard. True Judaism is up to date and cultural, but the lower East Side blinds people to Judaism.
