Bal Tigrah: Difference between revisions

#Some rishonim hold that there's no prohibition of bal tigra if there is a rabbinic enactment to do or not do a certain action.<ref>Rashba Rosh Hashana 16a writes that there's no prohibition of bal tosif when the rabbis enacted to do a certain action. His proof is that we keep [[Yom Tov Sheni]] and that isn't considered bal tosif since the rabbis enacted it for a reason. Then he extends this argument to bal tigra. The reason that it is permitted not to blow the shofar on the first day of [[Rosh Hashana]] when it falls out on Shabbat is because it is considered a rabbinic enactment for a need. Ritva Rosh Hashana 28b agrees.</ref> Others disagree.<ref> The Turei Even Rosh Hashana 16a disagrees because there is no reason a rabbinic enactment could undo a Biblical prohibition of bal tigra. The Haghot Imrei Baruch answers that bal tosif or bal tigra are relevant when the offender is changing the Torah, however, when the intent is to follow the rabbinic enactments there is no change of the Torah. Additionally, the Turei Even asks how the Rashba could explain the Gemara Zevachim 80a that there is bal tosif and bal tigra when dealing with a mixture of blood even though there is a real need and the rabbis should have enacted a solution. Lastly, Turei Even points out that Rashi Eruvin 96a s.v. vod clearly seems to disagree with the Rashba as he asks the question of how we could do [[Yom Tov Sheni]] and not violate Bal Tosif and doesn't answer it like the Rashba did.</ref>
