¥See Paul's remarks in Romans 2:17-24 regarding Jewish self-righteousness:
–17 (NIV) Now you, if you call yourself a Jew; if you rely
on the law and brag about your relationship
to God; 18 if you know his will and
approve of what is superior because you are instructed by the law; 19 if you are convinced that you are a guide
for the blind, a light for those who are in
the dark, 20 an instructor of the foolish, a
teacher of infants, because you have in the law the embodiment of knowledge and truth– 21 you, then, who teach others, do you not teach yourself? You who preach against
stealing, do you steal? 22 You who say that people should
not commit adultery, do you commit
adultery? You who abhor idols, do you rob
temples? 23 You who brag about the law, do you dishonor God by breaking the law? 24 As it is written:
"God's name is blasphemed among the Gentiles
because of you."
