You pay tithes of mint and dill and cummin,
and have neglected the weightier things of the law:
judgment and mercy and fidelity.
But these you should have done, without neglecting the others.
Blind guides, who strain out the gnat and swallow the camel
-- Mt 23:23-26
In times past, cruel practices were commonly used by legitimate governments to maintain law and order, often without protest from the Pastors of the Church, who themselves adopted in their own tribunals the prescriptions of Roman law concerning torture. Regrettable as these facts are, the Church always taught the duty of clemency and mercy. She forbade clerics to shed blood. In recent times it has become evident that these cruel practices were neither necessary for public order, nor in conformity with the legitimate rights of the human person. On the contrary, these practices led to ones even more degrading. It is necessary to work for their abolition. We must pray for the victims and their tormentors.
