TempleSinai originated with a group of seven families who, in 1950, began to meet unofficially at various locations. They sought a new interpretation of Reform Judaism, which they felt had become doctrinaire. In doing so, they endeavored to establish“a congregation of equals.”

After more than a year of these unofficial gatherings, these families adopted a name, Temple Sinai, and received a charter from the UAHC on April 1, 1951. The early days of Temple Sinai featured wandering from one meeting place to another – from the Dupont Circle Hotel to the Wardman Park Hotel to 16th Street at the First Congregational Church. However, the group gathered momentum, and it was joined by more worshippers, a cantor, and, finally, by its first rabbi, the newly-ordained Balfour Brickner.

In 1952, at the invitation of Dean Francis B. Sayre, Jr., the wanderers found a semi-permanent home in the Bethlehem Chapel of the National Cathedral, where they began to expand their activities. Committees and affiliates formed, and the religious school attracted increasing numbers of young parents. Innovative bar and bat mitzvah standards were developed, stressing no distinction between sexes. As the Temple grew, its members began planning for a more permanent home. By 1953, the members took a first step toward permanence: the purchase of 3.18 acres at 31st Street and Military Road, Northwest, in the Chevy Chase DC neighborhood, for $47,750.

By this point, the Temple had membership of over 700, a religious school larger than any in the metropolitan area, a newly formed Sisterhood, and a Brotherhood and Sinaites youth group. The cornerstone for Temple Sinai’s new home was laid in October 1957. The temple was designed to suggest a tent-like shelter in the wilderness, with walls of glass from floor to ceiling. As a stone taken from the Wall of Aggripa was put in place at the dedication ceremony, the congregation said in unison:

And this stone, which I have set up for a pillar, shall be God’s house. May the significance of this ancient stone, drawn from the past and now being set in the present, serve through its strength as an inspiration for the welfare of our common future.

Change came to the Temple in July 1961, when Rabbi Brickner moved to New York to join the national staff of the UAHC and Rabbi Eugene Lipman was appointed as the new Rabbi. Rabbi Lipman stayed at the Temple until his retirement in 1985. He maintained and expanded the founders’ aspirations for vibrant, continued learning; for community social concern; and for flexibility and openness to change. Fred N. Reiner, Senior Rabbi of Temple Sinai since July 1, 1985, was elected by a congregation that recognized his commitment to the same ideals. Rabbi Reiner was joined in 1986 by Rabbi Mindy A. Portnoy. In 1994, Cantor Laura Croen became our first invested cantor. In June 2007, Assistant Rabbi Jessica L. Oleon succeeded Associate Rabbi Shena B. Potter (2003-2007). Rabbi Oleon leads Temple Sinai’s youth groups and assists in other rabbinical functions.

In 1993, Temple Sinai completed a major renovation to its building, which made all areas of the building accessible to persons with disabilities, expanded the library, modernized student classrooms, improved office space, and added the Bet Am, our small sanctuary.

Over the past twenty years, the Temple has initiated innovative programs in education, ritual life, and social action. In 1992, Temple Sinai congregants established Sinai Assisted Housing Foundation, a separate non-profit organization dedicated tohelping formerly homeless families with children become stable & self-sufficient. Through the work of the Foundation, Temple Sinai congregants supported the establishment of Sinai House, a four-unit apartment facility for families seeking both transitional housing and social support. Today, the Temple Sinai community continues to be a primary support for the Foundation and the work of Sinai House. Temple Sinai’s kallah study-friendship program has developed into as many as twelve ongoing groups meeting monthly throughout the year. Adult education remains vibrant, offering new courses each year and attracting participants from the entire community. Over 150 adults have become a bar or bat mitzvah through our adult b’nai mitzvah program. Post bar and bat mitzvah young people are invited to attend adult education classes, read from the Torah on the anniversary of their bar or bat mitzvah, and serve with other active volunteers on temple committees.

In recent years, we have expanded our worship offerings to respond to a range of constituencies and worship styles, with regular Shabbat services on Friday evenings (plus a monthly “Tot Shabbat” and a monthly service aimed at families with children in K through 3^rd grade), Torah study and Shabbat services every Saturday morning (plus a monthly lay-led service and a monthly clergy-led service for families with young children), multiple services on the Days of Awe, and services on each of the major festivals. This past year, we adopted Mishkan T’filah as our siddur.

Today, Temple Sinai's dynamic programs include several annual events: a Latke v. Hamentashen debate and adult Purim celebration in addition to intergenerational Purim Shpiel, creative service, and family carnival; a Sisterhood authors' roundtable; a Cantor's Concert that features our cantor, often in collaboration with other area cantors. We also offer an annual spring program that alternates between a Social Justice Shabbaton one year and a Scholar-in-Residence weekend the next year.
