In its current form, Humanistic Judaism was founded in either 1963 As a rabbi trained in
Reform Judaism with a small,
secular, non-theistic congregation, he developed a Jewish liturgy that reflected his and his congregation's philosophical viewpoints by combining Jewish culture, history, and identity with
humanistic outlooks while excluding all prayers and references to a god of any kind. This congregation developed into the
Birmingham Temple in
Farmington Hills, Michigan. It was soon joined by a previously Reform congregation in
Illinois and a group in
Westport, Connecticut. In 1969, all three congregations were organizationally united with other groups under the umbrella of the
Society for Humanistic Judaism (SHJ). The SHJ had 10,000 members across 30 congregations in the United States and Canada in 1994; however, there are many congregations that identify with Humanistic Judaism's teachings but are not members of the SHJ. As of 2020, the
Pew Research Center estimated that Humanistic Judaism, along with
Reconstructionism and other smaller denominations, constituted 4% of the United States's 7.5 million Jews. The
International Institute for Secular Humanistic Judaism (IISHJ), founded in 1986, is the academic and intellectual center of Humanistic Judaism. It currently has two centers of activity: the original in
Jerusalem and another in
Lincolnshire, Illinois. Rabbi
Adam Chalom is the dean of the IISHJ's American site. The IISHJ offers professional training programs for spokespersons, educators, leaders (also referred to in Hebrew as
madrikhim/ot or Yiddish as
vegvayzer), and rabbis, in addition to its publications, public seminars, and colloquia for lay audiences. ==Principles of belief and practice==
