Waskow took pioneering roles in supporting the full presence and equality of women and of
LGBTQ people in all aspects of Jewish life and religion, including same-sex marriage; in mobilizing opposition in the Jewish and general communities to the Vietnam and then the Iraq wars; beginning in 1969, after his first summer-long sojourn in Israel and visits to the Occupied Territories, urging a two-state peace settlement between Israel and Palestine; in treating the planetary climate and extinction crises as a profound concern of Torah, necessitating action by the Jewish community; and in urging the Jewish community to treat the increasing concentration of top-down power by small minorities of the ultra-rich and by giant corporations as the reappearance of "pharaoh" in modern American life. In 2011, he (with Daniel Sieradski) co-inspired the creation of "Kol Nidre in the Streets" as a part of
Occupy Wall Street. Since spring 2012 he has been a member of the Coordinating Committee of the US National Council of Elders, a network of veteran activists of the crucial justice and peace movements of the mid-20th century who are continuing their nonviolent social action and are partnering with the new movements of the 21st century. Waskow pioneered in the development of Eco-Judaism in theology, liturgy, daily practice, and activism—through his books mentioned above as well as
Torah of the Earth: 4,000 Years of Ecology in Jewish Thought Other activities included the Green Menorah organizing project of The Shalom Center, the Interfaith Freedom Seder for the Earth and climate-focused public actions drawing on traditional liturgies for Tu B’Shvat, Passover, Tisha B’Av, Sukkot, and Hanukkah, In 2010, Waskow joined in founding the Green Hevra, a network of Eco-Jewish organizations, and served on its stewardship committee till 2013. In 2012 he became a member of the steering committee of Interfaith Moral Action on Climate. He was also a practitioner of nonviolent civil disobedience who has been arrested in climate protests in the US Capitol, at the White House, and at Philadelphia conclaves of
fracking corporate leaders. In 2007,
Newsweek named him one of the fifty most influential American rabbis. In that year also, the Neighborhood Interfaith Movement of Philadelphia presented him its Rev. Richard Fernandez Religious Leadership Award, and the Muslim American Society Freedom Foundation presented him its Peace and Justice Award.
The Forward named him one of America's "Forward Fifty," creative leaders of American Jewish life. In 2014 he was honored by
T'ruah: The Rabbinic Call for Human Rights with its first Lifetime Achievement Award as a Human Rights Hero. In 2015,
The Jewish Daily Forward named him one of "America's most inspiring rabbis". In 2017, the
Reconstructionist Rabbinical College awarded Waskow its once-a-year honorary
doctorate of humane letters. Waskow taught as a Visiting Professor in the religion departments of Swarthmore College (1982–83, on the thought of
Martin Buber and on the
Book of Genesis and its rabbinic and modern interpretations);
Temple University (1975–76 on contemporary Jewish theology and 1985–86, on liberation theologies in Judaism, Christianity, and Islam); Drew University (1997–1998, on the ecological outlooks of ancient, rabbinic, and contemporary Judaism and on the synthesis of mysticism, feminism, and social action in the theology and practice of Jewish renewal);
Vassar College (1999 on Jewish Renewal and Feminist Judaism); from 1982 to 1989 on the faculty of the
Reconstructionist Rabbinical College (contemporary theology and practical rabbinics); and in 2005 on the faculty of the Hebrew Union College-Jewish Institute for Religion (the first course on Eco-Judaism in any rabbinical seminary). Beginning with his first arrest in 1963, in a walk-in to end racial segregation by a Baltimore amusement park, and continuing through his arrest at the US Capitol in 2016 in a protest calling for more democratic election processes in the US — getting what he called "Hyper-Wealth" out of election campaigns and ending
voter suppression aimed at disfranchising especially racial and ethnic minorities, the poor, the young, and the old— and most recently with arrests in Philadelphia at the ICE offices in protest of US governmental hostility to refugees and immigrants—he was arrested about 26 additional times, each time for a non-violent protest against racism, militarism, polluting the Earth, or interference with democratic process. He claimed each as a public honor and religious act, in the spirit of the remark by Rabbi
Abraham Joshua Heschel after the
Selma March for voting rights: "I felt as if my legs were praying." He continued to be a prolific writer and speaker in the public sphere on the topic of social justice through a Jewish Renewal lens.{{cite web|title=Rabbi Arthur Waskow calls for simultaneous "celebration and heartbreak" in America ==Death==
