QUESTION

Washington, DC

R’ Melamed (Peninei Halacha Shabbat 1:6:3, Shabbat 1:6:6) writes that kiddush ideally should be made with wine and that it is a mitzvah to share from the same cup with one’s wife.

QUESTION


Washington, DC

A Jewish single woman considering embryo adoption wants to know if she needs to look for Jewish embryos, or if it will be sufficient for her to be the gestational mother to have the child be considered Jewish.

When Bacon Falls on the Food: Bitul of Dry Food

January 29th, 2021|Kashrut|

The underlying principle of almost the entire field of practical Kashrut is that of bitul – the ability of a food to be considered “nullified” when it is mixed with other foods, assuming that it does not impart any taste, that it is not noten ta’am. This is intuitively understandable when, say, a drop of milk falls into a large pot of chicken soup, that is, when the two are fully mixed together and become one entity. We can then say: “All we have here is chicken soup. The milk – since it cannot be tasted – no longer exists.” But

November 26th, 2019|Tzedakah & Social Justice|

Can I use my ma’aser kesafim, tithes from my income, to contribute to my synagogue’s building campaign, and can I use it to pay my shul’s membership dues?

February 14th, 2018|Tzedakah & Social Justice|

Can I use my ma’aser kesafim, tithes from my income, to contribute to my synagogue’s building campaign, and can I use it to pay my shul’s membership dues?

Giving money to the building of a house of God is the theme of this week’s parasha:

Speak to the Children of Israel, and they that bring me an offering (terumah); from every person whose heart moves him to give, you shall take My offering (Ex. 25:2).

The second half of Shemot, in fact, is devoted almost exclusively to this project – the building of the Mishkan and the contributions in time, talent, and wealth that
