Reconstructionist Judaism

Reconstructionist Judaism is a Jewish movement based on ideas developed by Rabbi Mordecai Kaplan. He believed that Judaism is a changing civilization, not just a religion. This movement began within Conservative Judaism in the late 1920s and 1940s and became its own group in 1955. It opened a rabbinical college in 1967 and is now one of the five major Jewish groups in America.

The movement has many different beliefs. Jewish law, called Halakha, is not seen as strict rules that everyone must follow. Instead, it is used as a base to create meaningful Jewish practices that fit modern life. Reconstructionist Jews value modern ideas and make decisions about customs together, learning from traditional sources.

In 2011, the movement published a guide to Jewish practice. It explains that because Jewish law cannot be enforced today, people are free to choose how they follow it. The guide offers many different ideas and lets individuals and communities decide what works best for them.

Origin

Reconstructionism was created by Rabbi Mordecai Kaplan and his son-in-law, Ira Eisenstein, from the late 1920s to the 1940s. Kaplan started the Society for the Advancement of Judaism in 1922, aiming to help rabbis think in new ways about Judaism. In 1935, Kaplan wrote a book called Judaism as a Civilization: Toward a Reconstruction of American Jewish Life, which he said began the Reconstructionist movement.

Even though Kaplan didn’t plan for Reconstructionism to become its own group, it eventually did. In 1967, leaders decided to start a special school for training rabbis in Reconstructionist beliefs. The school opened in Philadelphia in 1968, helping Reconstructionist Judaism grow. It became the fourth major Jewish movement in North America, along with Orthodox, Conservative, and Reform. The second major movement to start in North America was Humanistic Judaism, founded in 1963 by Sherwin Wine.

Theology

Rabbi Mordecai Kaplan believed that many old ideas and practices in Judaism no longer fit with what we now know from science and history. He still believed in God, but not as a person. Instead, he saw God as the natural forces that help people grow and feel good about themselves.

Kaplan’s ideas about God are different from many traditional Jewish beliefs. Some people in Reconstructionist Judaism agree with him, while others have their own views about God. What is most important in Reconstructionist Judaism is the idea that Judaism is always changing and growing, and that Jewish people should help shape its future.

Because of this, some Reconstructionist Jews today have different beliefs about God, the Jewish people, and religious rules than Kaplan did. They believe each generation can decide its own way of understanding Judaism.

Jewish law and tradition

Reconstructionist Judaism believes that traditional Jewish laws need to be updated so they make sense today. Unlike some other Jewish groups, Reconstructionists usually try to follow Jewish traditions unless there’s a good reason not to. They see these traditions as helpful ideas rather than strict rules.

Reconstructionist Jews still enjoy many traditional practices. These include speaking Hebrew during prayers, studying the Torah, praying every day, wearing kippot and tallitot during prayer, using tefillin, and celebrating Jewish holidays. They may use special prayer books like Kol haneshamah, which mix Hebrew and English.

Beliefs

Reconstructionist Judaism is based on ideas from Rabbi Mordecai Kaplan. It sees Judaism as a way of life that grows and changes over time, rather than just a set of fixed beliefs. In 1986, leaders of this movement created a statement called the "Platform on Reconstructionism" to share their main ideas. This statement is not a rule but a way to show what many people in this movement believe.

Key beliefs include seeing Judaism as a human creation that develops naturally, not something controlled by divine power. People in this movement support moving to Israel and believe that decisions should be made by the whole community, not just by religious leaders. They also think the Torah is a product of Jewish history and culture, not inspired by a god. Instead of a traditional idea of God, they see God as a force that helps people improve themselves and live good lives. They also believe it is wrong to think any one group is specially chosen by a god.

Reconstructionist Judaism treats everyone equally, no matter their gender, or who they love. All roles are open to all people.

Jewish identity

Reconstructionist Judaism lets its rabbis decide for themselves whether to lead services for interfaith marriages. Some groups accept that a child with one Jewish parent, no matter which parent, is Jewish if they are raised in the Jewish faith. This is different from older rules, where only children with a Jewish mother were seen as Jewish.

The place of people who are not Jewish in these groups is still being discussed. Different synagogues have different rules. Most try to be welcoming while keeping some boundaries. The Jewish Reconstructionist Federation gave ideas for how groups can decide these rules, but each group makes its own choices.

In 2015, the Reconstructionist Rabbinical College decided to accept students who are in relationships with people who are not Jewish. This made Reconstructionist Judaism the first Jewish group to allow this. The group felt this was important because many younger Jews find older rules about these relationships unfair.

In 2016, some rabbis started a group called Beit Kaplan to express concerns about these changes. By July 2025, this group had 92 members.

While Reconstructionist Judaism supports liberal Zionism, some of its members do not. For example, many rabbis in Jewish Voice for Peace were trained at the Reconstructionist Rabbinical College.

Organizations

There are over 100 synagogues and groups, called havurot, mostly in the United States and Canada, that are part of Reconstructionist Judaism. As of June 3, 2012, the movement changed its structure. Now, a joint group made up of the Reconstructionist Rabbinical College and the congregational organization leads the movement.

In 2018, the movement’s name changed to Reconstructing Judaism. The movement has a youth group called No’ar Hadash and a summer camp named Camp Havaya located in South Sterling, Pennsylvania. The Reconstructionist Rabbinical Association is for rabbis who follow this tradition.

In April 2016, a new group of rabbis called Beit Kaplan was formed. After events in 2023, the group grew and now focuses on supporting Israel and Jewish unity. As of 2020, Reconstructionist Judaism made up about 4% of the Jewish community in the United States.

Relationship with other Jewish movements

Reconstructionist Judaism started as part of Conservative Judaism but now has friendly ties with Reform Judaism. However, Orthodox Judaism sees Reconstructionist Judaism and other non-Orthodox groups as not following Jewish law in the right way. The Jewish Reconstructionist Federation belongs to the World Union for Progressive Judaism, where it gained observer status in 1990.
