We should be better that those who commit heinous acts. It should not be an eye for an eye.
Actually this is not exactly correct. We don’t maim people who maim others but in other respects the punishment must fit the crime.* “when Our Lord says: “You have heard that it hath been said of old, an eye for an eye, etc.,” He does not condemn that law, nor forbid a magistrate to inflict the poena talionis, but He condemns the perverse interpretation of the Pharisees, and forbids in private citizens the desire for and the seeking of vengeance. For
God promulgates the holy law that the magistrate may punish the wicked by the poena talionis*;” (St. Bellarmine)
St Bellarmine here explains that Jesus isn’t retracting the right and duty of public authority to ‘punish’ sinners according to their crime. He is addressing the ‘perverse interpretation of the Pharisees’ and the tendency in private citizens to desire and seek vengeance.
Now in Jesus time and even more so today, ‘public authority’ isn’t established by prophecy and visions and angels. Leaders are not appointed directly by God as had been the case with the Chosen people. Public authority is a product of the common good. We the people appoint elected bodies to represent our desires and attitudes in the interests of that common good.
I’m assuming that the Pharisees, (knowing as we do, their lack of humility) were feeling a bit like God on earth, in their attitude to punishment. Perhaps getting off on idea of a mans right to divine retribution instead of humbly conforming to what advances the common good of all men as their mandate in effecting Gods will.
It makes sense that, while God directly appointed a leader, He would directly speak through that leader but when we the people take part in electing our leaders, we have to humbly accept that we the people cannot desire or seek vengeance through our creation… the public authority. The only authoritive leader in our frame who is not democratically elected would be the Pope and it makes more sense to submit to his direction on matters of faith today, than continue to go back to the old law as the Pharisees were doing.
