Romans 2:3

‘And do you reckon this, O man, who judges those who practise such things, and do the same, that you will escape the judgment of God?'

So let them just think about it. They have set themselves up as judges of others. Do they therefore really think that when they practise such things as they have condemned, they will escape unjudged? For God's judgment will be especially hard on those who judge others and yet do the same things themselves, whether they be judge, philosopher, Rabbi or Jew. If they pass judgment on others and yet do these thing do they really then reckon that they will escape the judgment of God? That would be to render God unjust.

It is one of the signs of man's depravity that men whose responsibility it is to maintain law and order, or who have the gift of speaking about the follies of mankind, or who are experts in the Law, can feel that they themselves are exempted from the strictures that they bring on others, even though they might indulge in the same sins. They feel that because they take a high moral tone they will somehow be excused, even though they fall short of what they require of others. One of the failings of the Jews was that they thought that because of their association with Abraham, and because they had the Law, they would be treated differently from others. Paul is saying, ‘no, that is not so'.
