General questions about non-Orthodox Jewish practice and ideology.
Heterodox Judaism refers to the various movements which broke off from Orthodox Judaism after the Enlightenment, including Reform, Conservative, and Reconstructionist Judaism. The leftwing of the Conservative movement, Reform, and Reconstructionist Judaism are often grouped under the term "Liberal Judaism"
Newer movements which would be considered under this umbrella are:
Jewish Renewal - described by Wikipedia as a movement which seeks to reintroduce the "ancient Judaic traditions of mysticism and meditation, gender equality and ecstatic prayer"
Humanistic Judaism - an atheistic offshoot of Liberal Judaism from the 1960s.
