Good explanation! But how do we resist?
[11] But when Cephas (St. Peter) was come to Antioch, I withstood him to the face, because he was to be blamed. Galatians, Chapter 2
“An unjust law is no law at all”. St Augustine
"On the other hand laws may be unjust in two ways: first, by being contrary to human good, through being opposed to the things mentioned above—either in respect of the end, as when an authority imposes on his subjects burdensome laws, conducive, not to the common good, but rather to his own cupidity or vainglory—or in respect of the author, as when a man makes a law that goes beyond the power committed to him—or in respect of the form, as when burdens are imposed unequally on the community, although with a view to the common good. The like are acts of violence rather than laws; because, as Augustine says (De Lib. Arb. i, 5), "a law that is not just, seems to be no law at all." St. Thomas Aquinas
