Rabbi Dr. Irving Yitzchak Greenberg, also known as “Yitz Greenberg,” was born on May 16, 1933. He is an American Modern Orthodox rabbi, historian, theologian, and author. He was ordained as a rabbi in 1953 by Yeshiva Beis Yosef in Brooklyn, where he said, “The Yeshiva taught that the Torah’s goal was to make a person into a mensch.” He earned a B.A. in History at Brooklyn College, and an M.A. and Ph.D. in American History from Harvard University. His Ph.D. work focused on American history. He is widely recognized as one of the most influential Jewish thinkers of the past half-century. In “The Triumph of Life,” he gives readers the culmination of his lifetime of reflections. It is his magnum opus. He tells us that his understanding of Judaism as “a world religion shaped my thinking for life.” I know Rabbi Greenberg. I agree with his views about Judaism, and I think we should all agree with him.
His 326-page book has 14 chapters that discuss a wide range of essential subjects, including creation, the dignity of life, humanity imitating God, tikkun olam (repairing and perfecting the world), the struggle of life against death, the lesson of the Holocaust, and much more. These subjects help readers understand what it means to be human, to be Jewish, and what is expected of us.
Greenberg tells us that Judaism is a religion of life, one that calls people to actively side with the forces of creation and compassion against death, oppression, and despair.
What distinguishes The Triumph of Life from other theological works is Greenberg’s insistence on optimism and hope. In discussing the devastation of the Holocaust, for example, he neither retreats into silence nor seeks easy consolation. Instead, he reframes the catastrophe as a moment that both tests and deepens our responsibility. Humanity’s power—scientific, political, and moral—has never been greater, and Greenberg urges that it be directed toward eradicating poverty, healing inequality, and transforming violence into partnership.
His book balances accessibility with intellectual depth. He writes with clarity and warmth, weaving together biblical exegesis, historical insight, and ethical reflection. His narrative invites readers—Jewish and non-Jewish alike—to view religion not as an unchangeable doctrine but as a living, creating, and evolving relationship aimed at the flourishing and improving of creation.
He achieves something rare in The Triumph of Life: a theology that is both deeply Jewish and profoundly universal. His call for an “ethic of power” and his vision of the triumph of life speak urgently to an age of ecological peril, social fracture, and technological changes. This is not only a summation of one thinker’s journey but a moral guidebook for humanity in search of purpose –a goal that God desires.
Rabbi Greenberg believes that Jews have specific responsibilities, but this does not belittle –not even a little bit –God’s love for all people. He writes that his father taught him that “Torah must be applied to make life better for human beings”-and this means not only Jews. He has been a pioneer in advocating positive relationships between Judaism and Christianity, moving beyond conflict toward mutual understanding. He co-founded and led institutions aimed at leadership development in the Jewish community, including pluralistic intra-Jewish education.
He is known for his theology of the Holocaust, called Shoah in Hebrew. He states that it challenges our understanding. The Nazis used it to harness power, destroying moral concepts. It raises the fundamental question of why God allowed Jews to suffer such an atrocious fate. Yet, it is a transformational event in Jewish history, requiring all people to rethink their religious views, such as the human relationship to God, God's hiddenness, and how we should act in modern times after seeing what occurred in the past. We need to emphasize our human responsibility and ethical use of power.
He explains that our relationship to God must be performed by tikkun olam, world repair and perfection, achieved through human growth in thinking, responsibility, and morality. ‘The present state of the world and the powers-that-be in it do not do justice to the uniqueness of every human being –and often deny or crush it. Therefore, the divine wants a perfected world for beloved humanity and other forms of life to live in.” Religion must not be passive belief but active collaboration with the divine to improve the conditions on earth for all humans and to enhance further what God created.
(Although unmentioned by Greenberg, this important idea that we must work to improve the world can be seen in the command that Jewish males circumcise the foreskin of their penis to enter the covenant with God. Some mistakenly think that this is done because the foreskin is a defect. Actually, the command to enter the covenant – which means, do what God desires – is a symbolic act that reminds people to improve what God created. This is also the meaning of Genesis 2:3: “God blessed the seventh day and hallowed it because God ceased creating on that day to do.” The final Hebrew word laasot, “to do,” requires humans to continue improving the creation.)
All of humanity must learn to work together to improve creation. Then, the future state –the repaired world –will result in equality, and “the uniqueness of every person will be honored and upheld in all the material conditions and spiritual interactions of daily life.”
Why do I respect Yitz Greenberg?
Because of his friendly attitude, intelligence, and rationality. He respects and helps all people, shuns passive piety, and encourages everyone to work together actively — as actively as we can — to create an improved world that everyone can enjoy.
