There is among the passions an anger of the intellect (mind), and this anger is in accordance with nature – that is courage . Without this anger a person cannot attain purity: we have to feel angry with all that is sown in us by the enemy. When Job felt this anger he reviled his enemies, calling them ‘dishonorable men of no repute, lacking everything good, whom I would not consider fit to live with the dogs that guard my flocks’ (cf. Job 30:1, 4). If we wish to acquire the anger that is in accordance with nature we must uproot all self-will, until we establish within ourselves the state natural to the intellect.
If you find yourself hating other people and resist this hatred, and you see that it grows weak and withdraws, do not rejoice in your heart; for this withdrawal is a trick of the evil spirits. They are preparing a second attack worse than the first; they have left their troops behind the city and ordered them to remain there.
If you go out to attack them, they will flee before you in weakness. But if your heart is then elated because you have driven them away, and you leave the city, some of them will attack you from the rear while the rest will stand their ground in front of you; and your wretched soul will be caught between them with no means of escape. The city is prayer. Resistance is rebuttal through Christ Jesus. The foundation is the inflammatory aspect (power) of the soul used correctly – that is courage
Let us stand firm in the fear of God, rigorously practicing the virtues and not giving our conscience cause to stumble. In the fear of God let us keep our attention fixed within ourselves, until our conscience achieves its freedom. Then there will be a union between it and us, and thereafter it will be our guardian, showing us each thing that we must uproot. But if we do not obey our conscience, it will abandon us and we shall fall into the hands of our enemies, who will never let us go. This is what our Lord taught us when He said: ‘Come to an agreement with your adversary quickly while you are with him in the road, lest he hand you over to the judge, and the judge deliver you to the officer and you are cast into prison’ (Matt. 5:25). The conscience is called an ‘adversary’ because it opposes us when we wish to carry out the desires of our flesh; and if we do not listen to our conscience, it delivers us into the hands of our enemies.
