A Rabbi or a Cantor (or anyone for that matter) can interpret and teach the laws of Judaism.
The closest there is to a 'current leader' in Judaism is the Chief Rabbinate of Israel, that gives the 'most authoritative' interpretation of the law; precisely how authoritative it is, however, is a matter for a 'characteristic divergence of opinions' to put it simply, in Judaism :)Answer:Judaism hasn't had a single leader for two thousand years, let alone a current one. Each Jewish community has its own Rabbi or Rabbis. Answer:There is no "current leader" in Judaism as Judaism is not a centralised religion.
