The holiday in question is YOM KIPPUR.
Yom Kippur.
It always has been, it has the remains of The Temple which is very important to Judaism. It is the holiest city in Judaism, above all others.
The Day of Atonement is Yom Kippur (Leviticus ch.23). This is the holiest day in Judaism and the day where even secular Jews attend synagogue. On Yom Kippur, Jewish people fast from all food and drinks for a complete 25hrs, starting just before sunset the previous day.
In Judaism, no Jews believe this.
Jews regard all of the books of the Hebrew Bible as holy. The holiest part of the Bible are the first 5 books, called, "The Torah".
If you consider yourself Jewish but do not follow Judaism, holding to no religion at all, then you are a "secular Jew". A significant proportion of Jews are secular Jews. Some Jews have adopted a form of Christianity and consider themselves Christian Jews or Messianic Jews.
The Ka'aba is a cubic structure located in a square adjacent to the Grand Mosque in Mecca, Islam's holiest city. In pre-Islamic times it was holy to Arabs of all religions - Jews, Christians and pagans. The Arabs believed that Abraham and his son, Ishmael, had built the Ka'aba. and they both were Judaism.
Israel is the homeland of the Jews. The word Israel also refers to all the Jews in the world.
There are Jews of all social strata, from indigent to billionaires.
The same as all other Jews. Prayers are conducted in synagogues; and the central holiest site is the Temple in Jerusalem, of which only the Western Wall now stands.
Christians believe that Jesus atoned for all of his followers' sins.Jews believe:that atonement is between the individual and G-d or whomever they 'sinned' against.it is not possible to atone for 'sins' not yet committed.it is not possible to atone for the 'sins' committed by another person.that atonement is achieved by apologising for your action in combination with resolving to never repeat that action and prayer.Furthermore, the Christian concept of sin doesn't exist in Judaism. In Judaism, the word in the Tanach (Jewish Bible) that is most often translated as 'sin' is an archery term that literally means 'to miss the mark'.
Yes, that is probably a fair statement to make, but not all Jews believe that, and in fact, not all Jews believe in God.
