Yes, but they can live "normal" lives like the rest of the outside world.
Jewish practice is not uniform in any stream of Judaism. You will find people who identify with every stream of Judaism who do not observe the Sabbath to the standards of their movement. Reform Judaism asks each Jew to consider the tradition and make the day holy. Some refrain from work entirely, although generally not to the extent of viewing all use of electricity as improper work. Some engage in activities that are enjoyable, even though strict interpretations of Jewish law consider them work. For example, many Jews will drive to a museum or a movie theater and pay the admission price because they see the underlying activity as honoring the Sabbath. Some are considerably less observant.
Any marriages on Shabbat are strictly prohibited by Orthodox and Conservative Jews, and by reason of custom, completely discouraged by Reform Jews. Most Jews that marry on Saturday are secular Jews, and therefore would not be married during a prayer service.
Black Jews observe Shabbat no differently than any other Jew.
There is no such thing as the "reform church" or a church of any kind in Judaism.
There is no prohibition against eating kosher meat during Shabbat. The reverse is true; it's expected that meat be eaten during the two main Shabbat meals. On Passover, Jews cannot eat leavened bread (whereas they can at other times of the year). Shabbat does not mirror this. The same kosher rules for the rest of the week apply on Shabbat. Jews cannot eat pork on any day of the week and conversely, Jews can eat tuna or kosher meat on any day of the week.
The Jewish people didn't believe that Jesus Christ was the true Messiah. They thought that he existed and was a good man, but was not the son of G-d. For this same reason they don't celebrate Christmas, Good Friday, Easter and any other holiday involving Jesus.
Some secular and Reform Jews think that cremation is acceptable.
Religiously observant Jews will never eat non-kosher foods, regardless of which day of the week it is. Less observant Jews will make a point to eat kosher food during Shabbat. Non-observant Jews usually don't pay any attention to whether or not the food they are eating is kosher.
In any place with Jews it can be celebrated....soem places with Jews are Israel, the US, Canada, and many other places
In the Old testimate in the creation narrative it says when G-d created on the 3rd day, it says it was "good" twice so Tuesday (the 3rd day for Shabbat) is a popular wedding day. ____ Most Jews get married on Sunday because it's the weekend. In reality, Jews can get married on any day but don't during Shabbat (Friday and Saturday) because there is a prohibition against listening/playing music on Shabbat. There are also certain holidays during which Jews don't get married.
The question as written is confusing.Religious Jews do not celebrate Christmas, so when it falls is completely irrelevant to any other extant Jewish celebration. Non-Religious Jews, some of whom celebrate Christmas in violation of Jewish beliefs on such, are usually not Shabbat-observant, so the restrictions of Shabbat that would directly interfere with Christmas preparations are irrelevant.
It does not mean anything specific. Reform Judaism is one branch of Liberal Judaism. So, ostensibly, non-Reform would mean any other branch of Liberal Judaism or it would refer to Orthodox Judaism. This is not a commonly-used term among Jews.
"A Sabbath day's journey" isn't a phrase used by Jews, it's Christian in origin. It's related to the prohibitions against work that apply to Shabbat which means that religiously observant Jews cannot travel by any means other than walking to Shabbat. This limits a journey to the distance a person can walk.
