[2][3][4] The movement originated as a semi-organized stream within Conservative Judaism, developed between the late 1920s and the 1940s before seceding in 1955,[5][6] and established a rabbinical college in 1967.
Thus, Reconstructionist Jews take Jewish law seriously as a source and resource that can shape expectations while not necessarily seeing themselves as bound by inherited claims of obligation.
Therefore, the practices in the guide are not monolithic, and commentators provide further insights, arguments, and alternative approaches that span the broad range of views that Reconstructionist rabbis and scholars advocate.
After being rejected by Orthodox rabbis for his focus on issues in the community and the sociopolitical environment, Kaplan and a group of followers founded the Society for the Advancement of Judaism (SAJ) in 1922.
Along with the establishment of the college, the Reconstructionist Rabbinical Association formed, which gave rabbis a strong network in the religious leadership of Reconstructionism.
[19] The founding of these institutions were great strides in its becoming the fourth movement in North American Judaism (Orthodox, Conservative, and Reform being the other three).
Kaplan believed that, in light of advances in philosophy, science, and history, it would be impossible for modern Jews to continue to adhere to many of Judaism's traditional theological claims.
[20] Kaplan affirmed that God is not anthropomorphic in any way, a position articulated by prominent medieval Jewish thinkers like Maimonides and in agreement with the rest of Rabbinic Judaism.
[23] To believe in God means to accept life on the assumption that it harbors conditions in the outer world and drives in the human spirit which together impel man to transcend himself.
To believe in God means to take for granted that it is man's destiny to rise above the brute and to eliminate all forms of violence and exploitation from human society.

[citation needed] Reconstructionist Judaism holds that the traditional halakhic system is incapable of producing a code of conduct that is meaningful for, and acceptable to, the vast majority of contemporary Jews, and thus must be reinterpreted in each new time period.
[13] Unlike classical Reform Judaism, Reconstructionism holds that a person's default position should be to incorporate Jewish laws and tradition into their lives, unless they have a specific reason to do otherwise.
Marc Shapiro called attention to the Reconstructionist Kol haneshamah taking liberties with the text, sometimes with an English translation "so blatantly inaccurate that we have no choice but to regard it as a conscious alteration.
"[27] In practice, Kaplan's books, especially The Meaning of God in Modern Jewish Religion and Judaism as a Civilization are de facto statements of principles.
There is no such thing as divine intervention; Judaism is an evolving religious civilization; Zionism and aliyah (immigration to Israel) are encouraged; Reconstructionist Judaism is based on a democratic community where the laity can make decisions, not just rabbis; The Torah was not inspired by God; it only comes from the social and historical development of Jewish people; The classical view of God is rejected.
Kaplan posits that revelation "consists in disengaging from the traditional context those elements in it which answer permanent postulates of human nature, and in integrating them into our own ideology...the rest may be relegated to archaeology".
[33] In making the decision, the movement considered that "many younger progressive Jews, including many rabbis and rabbinical students, now perceive restrictions placed on those who are intermarried as reinforcing a tribalism that feels personally alienating and morally troubling in the 21st century.
Presently, Beit Kaplan focuses on a "course correction" to reestablish the Reconstructionist movement's support for Israel and emphasis on the centrality of Jewish peoplehood.
