Editing Supererogation (section)

===Judaism===
In [[Rabbinic literature]] this principle is known as '''''lifnim mishurat hadin''''' (לפנים משורת הדין), lit. "beyond the line of the law".
See <ref name="Pfeffer">Rabbi Y. Pfeffer [https://dinonline.org/2015/07/27/lifnim-mishuras-hadin-crossing-the-line-of-the-law/ Lifnim MiShuras HaDin: Crossing the Line of the Law]</ref> for elaboration, and [[Hashkafa]] for general discussion.
Additional to its practical implications, the idea is foundational in the formulation of the various sub-philosophies of [[Orthodox Judaism]].
Cases where the principle is commonly applied are:<ref name="Pfeffer"/>
returning lost property; sharing a load; damage compensation; limits of competition in business.

Its best known philosophic formulation is by both [[Rashi]] and [[Nachmanides]] in their respective [[Torah commentaries]].<ref>Rabbi D. Movsas. [https://www.myjewishlearning.com/article/beyond-the-letter-of-the-law/ Beyond The Letter Of The Law]</ref> Commenting on [[Deuteronomy]] [https://www.sefaria.org/Deuteronomy.6.18 6.18]  “And you shall do that which is right and good in the eyes of God.” They ask "what new instructions does this verse add"? Surely, doing what is “right and good” is already a part of the numerous injunctions already presented there. Both understand this verse to denote a level of behavior that is above the letter of the law.

Although celibacy is generally defined as a sin in Judaism, with no stated exceptions within Reform Judaism, Reform Judaism teaches that the [[cultural mandate]] is no longer necessary, so procreation between Jews within this sect of Judaism may be viewed as supererogatory acts.
