The Spirit of Anger by St. John Cassian

We have heard that some people try to excuse this most destructive disease of the soul by attempting to extenuate it by a rather detestable interpretation of Scripture. They say that it is not harmful if we are angry with wrongdoing brothers, because God Himself is said to be enraged and angered with those who do not want to know Him or who, knowing Him, disdain Him. For example: "The Lord was angry and enraged against His people" (Psalms 106:40). And when the prophet prays and says: "Lord, do not rebuke me in your fury, nor in your anger correct me" (Psalms 6:1). They do not understand that, in their eagerness to concede human beings the opportunity for pernicious vice, they are mixing the injustice of fleshly passion into the divine limitlessness and the source of all purity. 

And so the monk who is on the way to perfection and who wishes to engage lawfully in the spiritual struggle must in every respect be free of the vice of anger and wrath. He should listen to what the vessel of election (Acts 9:15) commands of him: "All anger and indignation and uproar and blasphemy should be removed from you, as well as all malice" (Ephesians 4:31). When he says: "All anger should be removed from you," he makes no exception at all for us as to necessity and utility. He should strive to cure a wrongdoing brother, if need be, in such a way that, while bringing relief to one who is perhaps laboring under a rather slight fever, he does not get angry and bring upon himself the more baleful malady of blindness, so that as he sees the speck in his brother's eye he does not see the beam in his own eye (Matthew 7:3-5). For it behooves the one who wishes to heal someone else's wound to be healthy and untouched by any disease or illness, lest the gospel saying be applied to him: "Physician, heal yourself first" (Luke 4:23). And how will a person see to remove the speck from his brother's eye if he carries about a beam of wrath in his own eye? 

For any reason whatsoever the movement of wrath may boil over and blind the eyes of the heart, obstructing the vision with the deadly beam of a more vehement illness and not allowing the sun of righteousness to be seen. It is irrelevant whether a layer of gold or one of lead or of some other metal is placed over the eyes; the preciousness of the metal does not change the fact of blindness.

The Passions of Avarice, Anger, Sorrow, and Sloth

Avarice

The passion for the acquisition of wealth, said the Fathers, is not part of human nature and is due to a lack of faith and people’s sick way of thinking. This is why it requires no small effort to combat this passion, if, with the necessary vigilance over ourselves, we wish to achieve real salvation and the fear of God in our lives. If this passion takes root in us it becomes the most tyrannical of all. And if we become subject to its encouragement and habits, then we’ve lost everything, because Saint Paul says “For the love of money is the root of all evil” (I Tim. 6, 10), that is of anger, sorrow and everything else.

Indeed, the Fathers also called it idolatry, because, through avarice, many people have fallen away, not only from the Christian life, but have been damaged in body and soul, as Holy Scripture tells us. And the Fathers tell us that people who hoard  gold and silver and trust in themselves, do not believe in God, Who is actually looking after them.
