In the eyes of many in Israel, Jesus seems to be acting against essential institutions of the Chosen People: - submission to the whole of the Law in its written commandments and, for the Pharisees, in the interpretation of oral tradition; - the centrality of the Temple at Jerusalem as the holy place where God's presence dwells in a special way; - faith in the one God whose glory no man can share.
