"But I say to you, offer no resistance to one who is evil"
“Whoever keeps the whole Law but falls short in one particular has become guilty in respect to all of it” (Jas 2:10). What is this one law if not true love, perfect charity? It is of this that Saint Paul also said: “For the whole Law is fulfilled in one statement, namely: 'You shall love your neighbor as yourself'” (Gal 5:14)...
For true charity is patient in adversity and moderate in prosperity; strong in painful suffering, joyful in good works; completely safe in temptation. It is very gentle among genuine brothers, very patient among the false. It is innocent in the midst of snares, groans in the midst evildoing, and breathes naturally in the truth. It is chaste in the married woman, Susannah, in the widow, Anna, in the virgin, Mary (Dn 13:1f.; Lk 2:36). It is humble in Peter's obedience and free in Paul's arguments. It is human in the witness of Christians, divine in the forgiveness of Christ. For true charity, beloved brethren, is the soul of the whole of Scripture, the strength of prophecy, the structure of knowledge, the fruit of faith, the wealth of the poor, the life of the dying. So keep it faithfully; cherish it with all your heart and all the strength of your soul (cf Mk 12:30).
