I know very little about Judaism so this thread should be interesting.
In terms of belief and practice what are some differences between Reform Jews and Orthodox Jews?
I have heard that Jews do not believe in Hell or Heaven or in an afterlife. Is this true?
1. That's a really big question, actually. There are a number of different groupings of
Orthodox Jews, all of whom have a particular angle on Orthodoxy. The basic tenets of Orthodoxy tend to be that the Torah was literally given by God to Moses on Sinai, and thus all of the commandments and precepts present therein are non-negotiable. Orthodox Jews also study the Talmud, or oral law passed down through Rabbinical tradition, as another central source of Jewish law. Many Orthodox Jews tend to believe that the Earth is literally 5768 years old. All Orthodox Jews keep to the strictest of Kashrut (dietary laws), and take the 613 commandments of Torah as canon law. Many Orthodox Jews dress in traditional style - they're the ones with the black hats, forelocks of hair, and long black suits.
Even within Orthodoxy, there is a diversity of opinion as to canonical law, and thus several sects of Orthodoxy exist. All Orthodox Jews adhere to the Thirteen Principles of Maimonedes (referenced
here).
Chassids, and Lubavitch Jews, adhere to mysticism and Kabbalah, and tend to venerate the central rabbi, or Rebbe, of their sect, sometimes even declaring him to be the Messiah. For example, the
Chabad-Lubavitch community venerates their Rebbe Menachem Mendel Schneerson.
That's a bit of a really brief overview of Orthodox Judaism.
Reform Judaism split off from Orthodoxy in the 19th century in Germany, during an argument about assimilation within society at large versus preserving traditional values. Reformers believed that to be more accepted within society, Jews must adopt secular customs and dress, and adapt worship services and other traditions to more closely mirror the dominant Protestant ethic. In its early history, Reform Judaism eschewed most things that would identify it with "traditional" Judaism, abandoning the laws of kashrut, the wearing of yarmulkes, even changing the layout of the synagogue. In Orthodox synagogues, the pulpit sat in the middle of the room surrounded by the congregation. In the new Reform temples, the pulpit was moved to the front of the congregation. Hebrew was suppressed, and prayers were said in the colloquial tongue. The Bar Mitzvah was abandoned in favor of a "confirmation" ceremony adapted from the Christians, though it was re-introduced (along with the new Bat Mitzvah for girls) pretty early on. Some other extreme examples: Men would wear top hats instead of yarmulkes, and on Rosh Hashana (the Jewish New Year) when a shofar (ram's horn) is traditionally blown to signal the new year, a trumpet would be blown instead.
As Reform Judaism has evolved over the past century and a half, particularly after it moved to America, there has always been a struggle between those who argue for greater assimilation and those who wish to return to more traditional modes of worship. Recently, I'd say within the past 40 to 50 years, there has been a move to reconcile Reform Judaism with its more traditional roots. Hebrew education is a standard part of Temple school curricula. Services are conducted both in Hebrew and the colloquial tongue. Some Reform Jews keep kosher. Yarmulkes and tallitot (prayer shawls), while still optional, are being worn by a larger portion of Reform Jews.
Reform Jews hold that scripture is divinely inspired, and Reform Jews don't tend to take Biblical history literally. Most Reform Jews accept scientific explanations for the origins of the Universe, evolution, etc. The guiding principle of Reform Judaism is that the individual has to take charge of his or her spiritual growth, and decide for himself or herself what commandments, or mitzvot, are relevant and necessary, and how to apply them. For example, it is up to the individual to decide whether to keep kosher, whether and how stringently to fast on Yom Kippur (the day of Atonement), whether to wear a yarmulke, and, most particularly, what to believe about the nature and existence of God. Reform Jews also study and take inspiration from Judaism's Prophetic traditions.
With regard to God, all Jews accept the Sh'ma as the central tenant of our faith:
"Hear oh Israel, Adonai is our God, Adonai is one."
Adonai is a Hebrew word meaning "God" that is substituted for the "lost" Name of God that hasn't been uttered since the days of the Temple in Jerusalem.
Thus, we are pure Monotheists - there is only one God. Reform Jews have decided to remove gender from the identity of God, because we don't have a definitive answer as to the exact nature of God. Thus, our worship services never refer to God as "He," and all gender-specific language has been removed. We have also adapted certain prayers within the liturgy to be more gender-inclusive.
2. Heaven and Hell. I really can't give you any kind of definitive answer on this, because there is no consensus in Judaism on this topic - I mean, none whatsoever. I guess that's really the definitive answer. Some Jews believe in Heaven and Hell, though what they mean by those concepts may differ widely from Christian norms.
The thing about Judaism is that it's not about punishment versus reward, which is where Heaven and Hell come into play. Jews worship and follow traditions not to gain an eternal reward or avoid an eternal punishment, but rather to connect with the larger community of Jews and our history as a people. We focus on this world, the here and now, because this is what we know for sure exists. One of the fundamental principles of Judaism is Tikkun Olam, repairing the world, so that the next generation can live as well or better than we did.
