Shabbat

Dear Rabbi My parents keep a kosher home and observe shabbat. This shabbos my parents will be hosting friends who are secular/reform who are are not shomer, but plan to keep this shabbat at my parents home. In regards to the wine, when people come to shabbat dinner that are not shomer they serve Mevushal. Since these friends will be keeping the shabbat can non Mevushal be served? Albeit, they have not previously kept shabbat or plan to keep shabbat in the future would it not be negatively Judging a Jew because they could have a positive expirence and thus propel them to keep the Shabat in the future? How many shabbats would a Jew need to keep, to be classified as a Jew who observes shabbat hence could pour non Mevushal wine without issue?

What is the source that teaches to light candles for Shabbat?

After the Marriv Amidah is said on Friday evening, we recite: (1) Va-Ya-Chu-Lu (2) Baruch Atah ... Ko-Nei Sha-Ma-Yim Ve-Aretz (3) Magen Avot Is a minyan required to recite Birkat Me-eyn Sheva [combination of (2) and (3)]? If yes, why?

Shalom aleichem Rabbi Lauffer. Thank you for answering my last question. A Jew b'shogeg cooked grilled cheese by lighting a burner under a pan on Shabbos. He meant to do it and knew it was Shabbos, but he didn't know the penalty for it, which is s'kilah God forbid. So it qualifies as shogeg. By lighting this burner, he thereby warmed the pot next to it that contained completely cooled off, fully cooked soup that was fully cooked before Shabbos. Would another Jew be able to eat this soup, even though it may have been warmed by the other Jew's forbidden act, and it probably was because the soup pot is warm to the touch from being heated by the burner next to it. Or would it possibly be mutar to eat it because the Jew would have eaten it anyway, even without it being warmed up. Thanks a lot.

Hi Rabbi, why is there Kiddush Friday night? Thanks!

Shalom aleichem Rabbi Lauffer. Thank you for answering my last question. If a pillow contains a zipper, would that pillow be muktzeh on Shabbos, and if not, would the zipper itself be muktzeh on Shabbos, even when it is attached to the pillow? Thanks a lot.

Shalom aleichem Rabbi Lauffer. Thank you for answering my last question. Is one allowed to unscrew the top of a sippy cup on Shabbos, the top of the sippy cup containing the straw, dump out the water, put new water in the sippy cup and then screw the top back on, or would this be forbidden because one is thereby making a vessel? Thanks a lot.
