Since Christianity is topical here, let’s see what we can find in Christian lore to help us understand the way of the superior human being when confronting corruption in religion, clergy, and institutions.
There is a well known incident as related to us in the Hadith of Jesus son of Mary. One day “the morality police” of the Pharisee apparently thought they were being clever in shooting two birds with one stone (pun intended). They went to the quarter where prostitutes worked and dragged a woman caught in the act and brought her before that lovely one. This was to discredit him before the Israelites as his progressive and luminous teachings were indeed a threat to their station of power and prestige and control over the people. Jesus did not tear them a new one using words (even though certainly capable of it) nor did he pick up the stone and throw it at them (even though they certainly deserved it).
No. What he did was silently allude to the poor grasp of the people of the actual Law, and then with a simple statement he not only confronted the Pharisees with their own corruption and sinful nature, but also saved a soul from certain death. To their credit, the Pharisees in question were ‘self-reflective’ enough to get the message and leave in peace.
This is how he was inviting people to a superior understanding without alienating them (!) and at the same time clearly establishing the guilt of the standing church and its priests. In fact, this way was so effective that the Sanhedrin decided that they had to get rid of him, intent on murdering him.
Do you see a way to this goal without destruction?
