Do not let the sun go down on the anger of your brother (Eph. 4:26); that is, let no one be angry and enraged against his brother until the setting of the sun.
Woe is he who knowingly chooses to sin with the intention to repent when morning comes, for he knows not what the coming day or the night that precedes it will bring.
An elder prescribes the following rule of conduct for the monastic table: 'When you sit to eat, brother, do not be overcome by the demon of gluttony, which compels you to eat in a disorderly way and in haste and to desire to taste many kinds of food together. Learn to eat modestly and in an orderly way and maintain a measure of restraint.'
Just as the arena and the field of action tests the athlete, so also the Christian is checked in the arena of struggle as to whether he truly loves God. Patience in the struggle against various sins and courage in rushing out to apply the divine commandments characterize the fervent worshipper of Jesus.
Many people have the virtue of humility in some circumstances. They then succumb to a supposed demand of their social stature or profession and, under the guise of ‘social necessity’ or ‘professionalism,’ become arrogant in other circumstances. This is much like mixing soil and water in a container. When the container is untouched and at rest, the soil will settle and the water will remain sweet. But if the container is agitated, then the water and the soil are mixed and become mud. The mud then dries, the water evaporates, and only soil is left. Thus only a person of true peace, incapable of agitation, can actually maintain humble virtue, meanwhile tolerating in himself any ostensibly worldly behavior.
On days when a Saint is celebrated, Christians ought to pray more ardently, with contrition and love, and entreat the Saint to intercede with God for the salvation of their soul. The feast day of every Saint is for Christians a serious reminder of the great sufferings which the Saints experienced for the sake of Christ's faith. They were glorified by God and with glory they received a place in the Kingdom of Heaven. Let us then honor the Saints and invoke their help, in order that they might strengthen us in our prayer. And we may rest assured that our prayer will be listened to by God.
Do not judge one another, for you transgress the evangelical law, and 'every transgression and disobedience received a just retribution' (Heb. 2:2). 'Who are you to pass judgment on the servant of another?' (Rom. 14:4). Do you not know that the one who passes judgment goes astray through pride, and that everyone who exalts himself will be humbled (Luke 14:11) by the Lord, when temptation seizes him?
Abba Theon ate vegetables, but only those that did not need to be cooked. They say that he used to go out of his cell at night and stay in the company of the wild animals, giving them drink from the water he had. Certainly one could see the tracks of antelopes and wild asses and gazelles and other animals near his hermitage. These creatures always gave him pleasure.
A brother asked Abba Isidore the priest, 'Why are the demons so frightened of you?' The old man said to him, 'Because, ever since the day I began practicing ascesis, I have striven to prevent anger from reaching my lips.'
Even a pious person is not immune to spiritual sickness if he does not have a wise guide -- either a living person or a spiritual writer. This sickness is called prelest, or spiritual delusion, imagining oneself to be near to God and to the realm of the divine and supernatural. Even zealous ascetics in monasteries are sometimes subject to this delusion, but of course, laymen who are zealous in external struggles (podvigi) undergo it much more frequently. Surpassing their acquaintances in struggles of prayer and fasting, they imagine that they are seers of divine visions, or at least of dreams inspired by grace. In every event of their lives, they see special intentional directions from God or their guardian angel. And then they start imagining that they are God's elect, and often try to foretell the future. The Holy Fathers armed themselves against nothing so fiercely as against this sickness -- prelest.
