Judaism
There is a certain amount of truth in the claims that Judaism is a religion, a culture, and an ethnic group, none of these descriptions however is entirely adequate to describe what connects Jews to other Jews. Almost all Jews feel a sense of connectedness to each other that many find hard to explain, define, or even understand. The best explanation is the traditional one given in the Torah: that the Jews are a nation. Anyone who feels any sense of Jewish identity shares that sense of Jewish peoplehood. Jews refer to that nation as "the Jewish people" or "the Children of Israel". As a nation or people, Jews share common ideas, ancestry, and culture, but there is also room for diversity in each of these areas. The most important part of being a nation is that sense of interconnectedness. Judaism as a religion is very communally-oriented. For example, prayers are normally stated in the plural, and Jews are supposed to pray in communal groups. Many of the Jewish holiday observances are family or community-oriented; yet, even people who are not religious at all feel that sense of Jewish community. When Jews suffer or are persecuted, all Jews feel their pain. When a Jew does something illegal, immoral or shameful, all Jews feel the shame, and all Jews feel that it reflects on all Jews. And when a Jew accomplishes something significant, all Jews feel proud.
