As a general rule, decide whether a thing is permissible by the effect it produces within. Permit yourself what is constructive, but never what is destructive.
We see the water of a river flowing uninterruptedly and passing away, and all that floats on its surface, rubbish or beams of trees, all pass by. Christian! So does our life. . . I was an infant, and that time has gone. I was an adolescent, and that too has passed. I was a young man, and that too is far behind me. The strong and mature man that I was is no more. My hair turns white, I succumb to age, but that too passes; I approach the end and will go the way of all flesh. I was born in order to die. I die that I may live. Remember me, O Lord, in Thy Kingdom!
It was said of Abba Arsenius that once when he was ill at Scetis, the priest came to take him to church and put him on a bed with a small pillow under his head. Now behold, and old man who was coming to see him, saw him lying on a bed with a little pillow under his head and he was shocked and said, 'Is this really Abba Arsenius, this man lying down like this?' Then the priest took him aside and said to him, 'In the village where you lived, what was your trade?' 'I was a shepherd,' he replied. 'And how did you live?' 'I had a very hard life.' Then the priest said to him, 'And how do you live in your cell now?' The other replied, 'I am more comfortable.' Then the priest said to him, 'Do you see this Abba Arsenius? When he was in the world he was the guardian of the emperor, surrounded by thousands of slaves with golden girdles, all wearing collars of gold and garments of silk. Beneath him were spread rich coverings. While you were in the world as a shepherd you did not enjoy even the comforts you now have, but he no longer enjoys the delicate life he led in the world. So you are comforted while he is afflicted.' At these words, the old man was filled with compunction and prostrated himself saying, 'Father, forgive me, for I have sinned. Truly the way this man follows is the way of truth, for it leads to humility, while mine leads to comfort.' So the old man withdrew, edified.
This reversal of thoughts is the strongest means, not only for repelling accidental critical thoughts, but also for completely freeing yourself of this vice…
When Abba Agathon went down to the city to sell some of his baskets and to procure a little bread, he found near the market place an old, poor cripple. 'For the love of God, Abba,' the cripple began to plead on seeing the Saint, 'don't you, too, leave this poor wretch unaided. Bring me near to you.' Abba Agathon picked the man up and sat him next to him in the place where he had set up his baskets to sell them. 'How much money did you make, Abba?' the cripple would ask each time that the Elder sold a basket. 'Such and such,' the Elder would tell him. 'That's good enough,' the cripple finally said. 'Won't you buy me a little pie, Abba? That would be good of you, since I have not eaten since last evening.' 'With pleasure,' the Saint told him, immediately fulfilling the cripple's request. Shortly thereafter, the cripple requested some fruit. And then some sweet. Thus, for each basket that was sold, the Saint spent the proceeds, until, thanks to his patronage, all of the baskets and money were gone, without his having kept even two pennies for himself. More importantly, he did this all with great eagerness, even though he knew that he would thus go perhaps two weeks without any bread for himself. Since he had sold his last basket, the Saint got ready to leave the marketplace. 'So you're going?' the cripple asked him. 'Yes, I have completed all of my work.' 'Uh, do me the favor of taking me as far as the crossroads, and you can leave for the desert from there,' the strange old man again pleadingly said. The good Agathon took the cripple on his back and carried him to the place where he wanted to go, though with great difficulty, since he was exhausted from his day's work. As soon as he reached the crossroads and started to put down his living burden, he heard a sweet voice say to him: 'May you be blessed, Agathon, by God, both on earth and in Heaven.' The Saint raised up his eyes to see who it was who had spoken with him. The would-be old man had completely disappeared, since he was an Angel sent by God to test the Saint's love.
The flow of history confirms the reality of the Gospel: the Church is filled to overflowing with sinners. Does their presence in the Church reduce, violate, or destroy her sanctity? Not in the least! For her Head—the Lord Christ, and her Soul—the Holy Spirit, and her divine teaching, her mysteries, and her virtues, are indissolubly and immutably holy. The Church tolerates sinners, shelters them, and instructs them, that they may be awakened and roused to repentance and spiritual recovery and transfiguration; but they do not hinder the Church from being holy. Only unrepentant sinners, persistent in evil and godless malice, are cut off from the Church either by the visible action of the theanthropic authority of the Church or by the invisible action of divine judgment, so that thus also the holiness of the Church may be preserved.
Even if a person’s sin is not only obvious, but very grievous and comes from a hardened and unrepentant heart, do not condemn him, but raise your eyes to the wondrous and incomprehensible judgments of God; then you will see that many people, formerly full of iniquity, later repented and reached a high degree of sanctity, and that, on the other hand, others, who were on a high level of perfection, fell into a deep abyss. Take care, lest you also suffer this calamity through judging others.
BROTHER: What are fasting and prayer? OLD MAN: Fasting is the subjugation of the body, prayer is converse with God, vigil is a war against Satan, abstinence is being weaned from meats, humility is the state of the first man, kneeling is the inclining of the body before the Judge, tears are the remembrance of sins, nakedness is our captivity which is caused by the transgression of the command, and service is constant supplication to and praise of God. BROTHER: Are these able to redeem the soul? OLD MAN: When internal things agree with external, and manifest humility appears in the hidden works which are from within, verily, a man shall be redeemed from the weight of the body.
Go, sell all that belongs to you and give it to the poor and taking up the cross, deny yourself; in this way you will be able to pray without distraction.
The origin of the Christian life is in arousal by grace. A person who has heeded this arousal is not then deprived of guidance by grace and communion with it at all times, as it persists through proper attention to it.
