Level: Basic
This is a far more difficult question than you might expect. Judaism has
no dogma, no formal set of beliefs that one must hold to be a Jew. In Judaism,
actions are far more important than beliefs, although there is certainly
a place for belief within Judaism.
The closest that anyone has ever come to creating a widely-accepted list
of Jewish beliefs is Maimonides thirteen
principles of faith. Maimonides' thirteen principles of faith, which he thought
were the minimum requirements of Jewish belief, are:
As you can see, these are very basic and general principles. Yet as basic
as these principles are, the necessity of believing each one of these has
been disputed at one time or another, and the liberal movements of Judaism dispute many of these principles.
Unlike many other religions, Judaism does not focus much on abstract cosmological
concepts. Although Jews have certainly considered the nature of G-d, man,
the universe, life and the afterlife at great length Kabbalah and Jewish Mysticism, there is no mandated,
official, definitive belief on these subjects, outside of the very general
concepts discussed above. There is substantial room for personal opinion
on all of these matters, because as I said before, Judaism is more concerned
about actions than beliefs.
Judaism focuses on relationships: the relationship between G-d and mankind,
between G-d and the Jewish nation, between the Jewish nation and the land
of Israel, and between human beings. Our scriptures tell the story of the
development of these relationships, from the time of creation, through the
creation of the relationship between G-d and
Abraham, to the creation of the relationship
between G-d and the Jewish people, and forward. The scriptures also specify
the mutual obligations created by these relationships, although various movements
of Judaism disagree about the nature of these obligations. Some say they
are absolute, unchanging laws from G-d (Orthodox); some say they are laws
from G-d that change and evolve over time (Conservative); some say that they
are guidelines that you can choose whether or not to follow (Reform,
Reconstructionist). For more on these distinctions, see
Movements of Judaism in Judaism 101.
So, what are these actions that Judaism is so concerned about? According
to Orthodox Judaism, these actions include 613
commandments given by G-d in the Torah as well
as laws instituted by the rabbis and long-standing
customs. These actions are discussed in depth on the page regarding
Halakhah (Jewish Law) and the pages following
it in
Judaism 101.
