Pikuach Nefesh and Non-Kosher Organ Transplants

These sources address whether the prohibition against consuming non-kosher food is overridden when a non-kosher organ transplant is necessary to save a life. The sources establish the principle of Pikuach Nefesh — that nearly all Torah prohibitions yield to the imperative to preserve human life — and examine whether this principle applies to organ transplantation, which is not an act of eating in the conventional sense.

These sources establish that preserving human life overrides Shabbat restrictions entirely, and explore how this principle applies to cyber-defense operations.

Business Transactions with Churches in Halacha

Jewish law prohibits certain business dealings with non-Jewish religious institutions, particularly around their festivals, out of concern that profits will support their worship. These sources examine when commercial transactions—such as purchasing services or advertising space—constitute forbidden benefit to an idolatrous institution and under what circumstances such transactions may or may not be permitted.

Advertising With Non-Jewish Religious Institutions

Sources explore the halachic permissibility of commercial transactions with churches and other houses of worship, drawing on the biblical prohibition of lo techanem (not granting free favor to idolaters) and its Talmudic interpretation. The discussion examines when such transactions are forbidden, permitted, and how prior acquaintance affects the application of these rules.
