Halakhic Rulings on Heretics and Apostates
Jewish legal sources establish the status of minim (heretics), apikorsim (heretics/epicureans), and meshumadim (apostates) as individuals outside the community of Israel with no obligation—and in some cases a positive duty—to preserve their lives. The sources range from Tanakh narratives of zealous religious violence to Talmudic rulings and Maimonidean codification of their exclusion from communal life and the World to Come.
מוֹרִידִין וְלֹא מַעֲלִין
The Permissibility of Killing Animals
Jewish sources address whether and under what conditions animals may be killed for human use. The sources trace the biblical permission to eat meat as a post-Flood concession to human appetite, establish the principle of minimizing animal suffering (tzaar baalei chayyim), and codify ritual slaughter as the exclusive permissible method.
לא נתנה בשר אלא לתאוה
Bal Tosif and Lo Sasur: Adding and Subtracting from Torah
These twin prohibitions forbid adding new commandments to the Torah or subtracting from existing ones. The sources explore the Biblical foundation of these laws, their application through rabbinic authority, and the crucial distinction between legitimate rabbinic enactments and unauthorized innovations that violate these prohibitions.
