At the opening of this week’s parashah, God demands holiness from us, kedoshim tihyu. God wants us to realize a higher version of ourselves through refining our attitudes and behaviors. God wants us to be better than ordinary human beings by tapping into our capacity for holiness and excellence. However, holiness at its core is designation and separation, and a drive towards holiness can also be isolating, driving a wedge between us and our family and neighbors who do not have the same religious or spiritual ambitions. How do we know when we are truly being holy and when do we run the risk of becoming holier than thou? How do we prevent our quest for holiness from having negative interpersonal effects?
