Introduction

Abraham Joshua Heschel (January 11, 1907 – December 23, 1972) was a Jewish rabbi, theologian, philosopher, and social activist widely regarded as one of the most influential Jewish thinkers of the 20th century. His work wove together spirituality, ethics, mysticism, and prophetic witness. Heschel’s emphasis on wonder, moral responsibility, and the prophetic call resonates far beyond religious boundaries. His life bridged the tragic ruptures of the Holocaust, the struggle for civil rights in the U.S., and a deep vision of a spiritually engaged modern Judaism.

Early Life and Family

Heschel was born in Warsaw, Congress Poland (then part of the Russian Empire) on January 11, 1907. Moshe Mordechai Heschel and Rifka (née Perlow).

In 1916, when Heschel was nine, his father died from influenza, leaving his mother to raise the family. Kotzk Hasidic school.

The rise of Nazism and the outbreak of World War II deeply impacted him. His mother and several siblings perished in the Holocaust; his maternal family and sisters were murdered or deported to concentration camps.

Education, Academic Life & Emigration

After his foundational Hasidic and yeshiva education, Heschel pursued broader Jewish scholarship and secular studies. He studied at the Hochschule für die Wissenschaft des Judentums (Berlin) and the University of Berlin, achieving both rabbinic ordination and a doctorate.

In March 1940 Heschel arrived in New York City, escaping the intensifying threats in Europe. Hebrew Union College in Cincinnati (serving for five years), before joining the Jewish Theological Seminary of America (JTS) in New York, where he became professor of Jewish ethics and mysticism and remained until his death.

At JTS, Heschel’s teaching and writing spanned biblical prophets, Jewish philosophy, Hasidic mysticism, and Jewish spirituality, always suffused with ethical urgency and religious depth.

Thought, Themes & Philosophy

Prophetic Vision & Ethics

Heschel saw the Hebrew prophets not merely as historical figures but as living voices whose demands of justice, mercy, and attention still call humanity today. His writing The Prophets (1962) is a central work in his attempt to recover the prophetic voice for modern times.

He held that “Some are guilty, but all are responsible,” stressing the collective moral responsibility of society to address injustice.

Wonder, Awe & Spiritual Attitude

One of his signature ideas is that religious life begins in wonder (radical amazement). He urged that we see the world not as mundane and given, but alive with mystery and infinite depth.

He wrote,

“Wonder is an intuition for the dignity of all things … it enables us to perceive in the world intimations of the divine.”

And,

“Our goal should be to live life in radical amazement … never treat life casually.”

Time, the Sabbath & Holiness of Time

Heschel placed great emphasis on time as sacred. In The Sabbath (1951), he argued that the Sabbath is not about owning or controlling space, but about consecrating time — moments of pause, reflection, and holiness.

He observed:

“The meaning of the Sabbath is to celebrate time rather than space … to turn from the results of creation to the mystery of creation.”

Engagement & Social Justice

Heschel believed that spirituality and social action are inseparable. He marched with Martin Luther King Jr. in Selma, famously commenting,

“When I marched with Martin Luther King in Selma, I felt my legs were praying.”

He spoke out against racial injustice, the Vietnam War, and also engaged in interfaith dialogue.

He saw prayer not as escape, but as transformation:

“Prayer cannot bring water to parched fields … but prayer can water an arid soul, mend a broken heart, and rebuild a weakened will.”

Mysticism & Transcendence

His approach to Jewish mysticism was not speculation but a lived orientation—a way to “hold God and man in a single thought” and maintain spiritual tension between divine and human.

He warned against reducing religion to dogma or ritual alone; for Heschel, faith must be vibrant, compassionate, and capable of confronting suffering.
