Hello,

I have a few questions based on previous inquires posted.

  • The kind of cheeses that you mentioned in your Teshuva (mozarella, farmer’s, cheddar), even if they contain animal rennet, since the modern version doesn’t fall under the Talmudic category of Gevinah, they can be eaten? I understand that modern animal rennet used in most commercial/industrial cheeses today is inedible and basically a chemical. I guess the problem would be with super fancy traditional cheeses.
  • In a previous questions of one user you mentioned that in reality a wallet with debit/credit cards isn’t necessarily Muktzeh. I guess that, if you are in a place with an Eruv and you need to carry your ID due to safety concerns or because you are in a different country, there is no issue with carrying it as usual in your wallet even if it has some bills and cards, right?
  • If you are in a country with safety concerns or dangerous, that really require that you carry a phone and your ID for real safety, and you don’t have an Eruv, can it be done as usual for the reasons mentioned?
  • You mentioned that credit/debit cards is similar to what the Gemara permits when a person buys on credit. If you are in a place with an Eruv and in an emergency case you need to buy something for your meal that is definitely already prepared before Shabbat, like bread or soda for guests or even when travelling a cold vegetarian sandwich, etc. Can you do it?

I am asking the Halakhic concerns involved by these questions and I understand that even if permitted cultural sensitivity has to be taken into account.

Thank you!
