Sending a Shabbos Goy to prevent a Kashrus mishap

In this week’s episode, the topics discussed by Rabbi Braun include:

Kiddushin ring alternatives:

•         When the chassan’s ring is lost, is it preferable to use a borrowed ring or a coin?

•         May a paper bill or contemporary coin, which have no intrinsic value, be used for kiddushin the way a valuable coin could?

•         What are the halachic advantages of using a ring specifically?

•         Is it an option to use both a coin and a borrowed ring together, or would that backfire?

Sending a Shabbos Goy to prevent a kashrus mishap

•         May one ask a non-Jew to drive on Shabbos to warn people about milchig dessert at a sheva brachos?

•         Can a non-Jew be asked to do a melacha d’oraisa for a mitzvah need?

•         Does “michshol derabim” justify asking a non-Jew to do melacha?

•         What is actually the true nature of the michshol in the case of an unknown milchig dessert or torn eruv?

•         Does the possibility that one of the participants might be dangerously allergic to dairy create a pikuach nefesh justification?
