In Ezekiel 19 you have a basic account of the principles upon which the Torah is based. The context there is that God is telling the prophet to tell Israel about the fact that He judges a person only on the basis of a few basic principles. And the prophet then goes on to enunciate them. When a righteous person does right, that is he does not hurt others, does not lie or steal or commit adultery or do idolatry he will live, says the Lord. So you see right there the basic idea of R Shimon ben Yochai who is דורש טעמה דקרא [he says you go by the reason for the laws, not the letter of the law. Bava Metzia 119]. (There he argues with the sages who say you go by the exact meaning of the words, not the reason. For example. RS says you can take a pledge from a rich widow because the reason for the prohibition of taking the pledge of a widow is absent.])
So right there you see the important principle of Rav Israel Salanter in the Musar Movement--that is that the main idea of the Torah is to have good character. [To be a "mensch" as my Mom put it.]
[I wanted to add that right there in Ezekiel 19 you also see the fallacy of group pride. One of the comments of Ezekiel there complimenting a righteous son of some wicked person is that he did not go after גילולי בית ישראל "idols of the house of Israel". So you see a person is judged based on his own actions. Not which group he belongs to.
