The concept of chillul hashem is prevalent in the Tanakh and is often referenced by modern Jews as a reason to uphold the highest moral standard.
[5] Some rishonim (medieval commentaries) maintain that the requirement to give up one's life under these circumstances applies only when the individual is being called upon to actively commit a sin.
For example, if a Jewish leader or someone perceived to be righteous is seen acting improperly, their actions constitute a chillul hashem.
Thus, any time a Torah scholar or rabbi acts improperly in front of others, they have committed a chillul hashem.
[7] By acting as an upstanding and righteous people, and by following the commandments of the Torah, Jews seek to sanctify God's name and fulfill the mandate of being an Or La'goyim, a light unto the nations.
