MAJOR JEWISH RELIGIOUS DENOMINATIONS

REFORM: Liberal denomination that emphasizes Jewish ethics and the concept of tikkun olam (“repairing the world”), which promotes engaging in social justice work. Religious dietary and observance laws are optional. 

  • Additional smaller liberal Jewish denominations include Reconstructionist, Renewal, and Humanistic, which emphasize Judaism as an evolving culture with shared historical memory.

CONSERVATIVE: Centrist denomination that maintains many traditional practices, but updates some to suit modern sensibilities. Many keep kosher and some observe Shabbat and Jewish holidays by refraining from work.

  • Note that "Conservative" in this case does not refer to political leanings.

ORTHODOX: Strict interpretation, application, and observance of Jewish laws, holidays (refraining from work, commerce, electricity) and dietary restrictions (kashrut). 

  • Modern Orthodox Jews tend to obtain high levels of secular education and live lives more integrated into mainstream society. 
  • Haredi Jews tend to live and learn separate from mainstream society, and dress more distinctively and moderately. Although sometimes referred to as “ultra-Orthodox,” they prefer Haredi, which means those who tremble in fear of God.

JEWISH OBSERVANCE

SHABBAT: Weekly sabbath begins at sundown on Friday and ends at nightfall on Saturday. This day of rest often involves disconnecting from technology, spending time with family and friends, and attending synagogue. A family meal on Friday night features candle lighting, challah bread, and wine.

  • Greeting: Shabbat Shalom!

HIGH HOLIDAYS: The Jewish holidays of Rosh Hashanah (Jewish New Year) and Yom Kippur (Day of Atonement) occur in the fall (Sept./Oct.) and are widely celebrated and observed by the vast majority of American Jews, who will refrain from work, attend synagogue, and gather with family.

KOSHER/KASHRUT: Jewish dietary laws that stipulate that meat and milk products cannot be eaten together, and certain animals cannot be eaten at all (e.g., pork; shellfish). Many Jews who keep kosher, particularly Orthodox Jews, will only eat food that has been prepared under the supervision of a rabbi to ensure that all kashrut laws have been strictly followed.

KOSHER FOR PASSOVER: Special dietary laws for the 8 days of Passover, when matzah (unleavened cracker-like flatbread) is eaten, and it is prohibited to eat leavened foods like bread and other grain products.

SYNAGOGUE: A place of worship for Jews; may be referred to as a temple or shul. Not to be confused with church, which is not a Jewish term. Synagogues typically have a sanctuary for communal prayer, plus rooms for study and social events.

JEWISH LIFE CYCLE EVENTS

BAR/BAT MITZVAH: Jewish coming-of-age ritual that involves extensive preparation and study, a ceremony at the synagogue, and a celebratory meal or party. Bar mitzvah (boys) at age 13; Bat mitzvah (girls) at age 12 or 13. 

  • Greeting: Mazal Tov!

BRIS/BRIT MILAH: The circumcision and naming ceremony on the 8th day after a baby boy’s birth, marking entrance into the Jewish community, followed by a celebratory meal. 

  • Greeting: Mazal Tov!

SIMCHAT BAT: The naming ceremony for a baby girl, celebrated any time during the first year of life, marking the baby’s entrance into the Jewish community, followed by a celebratory meal.

  • Greeting: Mazal Tov!

SHIVA: A week-long period of mourning for direct relatives after the burial of the dead. Customary practice is a donation to a charity important to the deceased, in lieu of flowers. 

  • Greeting: May your loved one's memory be for a blessing.

WHY DO THE DATES “MOVE”?!

All Jewish religious observances begin on the evening before the date indicated on conventional calendars and conclude at nightfall on the day of the holiday. The exact dates of Jewish holidays and observances differ each year because the Hebrew (Jewish) calendar is lunar-based. 

VARIATION IN OBSERVANCE

There is a wide variety of religious practices among Jews; therefore, some Jewish students and staff may be absent due to observance of holidays more than others. Most Jews across the religious spectrum do not work or attend school on the High Holidays (Rosh Hashanah and Yom Kippur; dates in red). Orthodox and some Conservative Jews will not work or attend school on “no-work” holidays (dates in blue). Jews who are strictly observant will also not write, drive, use any electricity or technology, or engage in commerce on these days.
