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.
What can God do with one who willfully gives himself over to the world, and is deceived by its pleasures, or led astray by material wanderings? The man to whom He gives help is the one who turns away from material pleasures and from his former habits, who drags his mind at all times to the Lord, whether it will or not, who denies himself and seeks the Lord only. This is the man whom He keeps under His care: who guards himself on every side from the snares and entanglements of the material world, who works out his own salvation with fear and trembling, who passes with all heed amidst the snares and entanglements and lusts of this world, and seeks the help of the Lord, and hopes by His mercy to be saved through grace.
This reversal of thoughts is the strongest means, not only for repelling accidental critical thoughts, but also for completely freeing yourself of this vice…
Christians should judge no one, neither an open harlot, nor sinners, nor dissolute people, but should look upon all with simplicity of soul and a pure eye. Purity of heart, indeed, consists in seeing sinful and weak men and having compassion for them and being merciful.
Faith is the sincere confession that God, Who is worshipped in the Trinity, Who created all things and provides for all, saves us who are fallen, through the power of the death on the Cross of the incarnate Son of God, by the grace of the Most Holy Spirit in His Holy Church. The beginnings of renewal, which are established in this life, will appear in all their glory in the future age, in a way that the mind cannot comprehend nor the tongue express.
Each Christian, especially a priest, should follow in example the goodness of the Lord, that everyone should be invited to partake of the Lord's food at your table. The miser is an enemy of the Lord.
He Who before our offence forbids us to sin, after our offence ceases not from waiting for us to repent, He Whom we have rejected calls after us. We have turned away from Him, but He has not turned away from us.
Reverence with all the powers of your soul all the sacraments, and say to yourself in respect to every sacrament before the celebration or the communion of it: `This is God's mystery. I myself am only the unworthy witness or partaker of it.' Otherwise our proud intellect even wishes to search out God's mystery, and, if unable to penetrate it, rejects it as not coming under the small measure of our intellect.
In order not to be in daily bondage to the passions and the Devil, you must set yourself an object to aim at, have this object constantly in view, and endeavor to attain it, conquering all obstacles by the name of the Lord. What is this object? The Kingdom of God, the Divine palace of glory, prepared for believers from the creation of the world. But as this object can only be attained by certain means, it also is necessary to have such means at one's disposal. And what are these means? Faith, hope, and love, especially the last. Believe, hope, and love, especially love, disregarding all obstacles; love God above everything and your neighbor as yourself. If you have not sufficient strength to preserve in your heart these inestimable treasures, fall down oftener at the feet of the God of Love. 'Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you' (Matt. 7:7-8) - for He Who has promised is true.
There is one method which, if practiced with full attention, will seldom allow anything passionate to slip unnoticed into the heart. This is to examine our thoughts and feelings, so as to discover which they tend: towards pleasing God or towards pleasing ourselves.
Sometimes younger people, or those of equal station, or older ones, teach you by means of hints which you cannot endure, and you are vexed with your teachers. We must endure and listen with love to everything useful coming from anyone, whoever he may be. Our self-love conceals our faults from us, but they are more visible to others. This is why they remark them to us. Remember, that 'we are members one of another,' and are thus obliged to mutually correct each other. If you do not bear being instructed by others, and are vexed with those who teach you, it means that you are proud, and this shows that the fault of which others hint that you should correct yourself is really in you.
Do you not mock at the faults of your neighbor; do you not despise him; do you not nourish hatred against him on account of them? 'Charity beareth all things.' Remember this, and bear with the faults and iniquities of your brother, that God may bear with yours. Have patience with the infirm members, for we are all one body in the Lord.
My son, says Scripture, if you come to serve the Lord, prepare your soul for trial, set you heart straight, and patiently endure (Eccles. 2:1-2). And elsewhere it is said: Accept everything that comes as good, knowing that nothing occurs without God willing it. Thus the soul that wishes to do God's will must strive above all to acquire patient endurance and hope. For one of the tricks of the devil is to make us listless at times of affliction, so that we give up our hope in the Lord. God never allows a soul that hopes in Him to be so oppressed by trials that it is put to utter confusion. As St. Paul writes: God is to be trusted not to let us be tried beyond our strength, but with the trial He will provide a way out, so that we are able to bear it (I Cor. 10:13). The devil harasses the soul not as much as he wants but as much as God allows him to. Men know what burden may be placed on a mule, what on a donkey, and what on a camel, and load each beast accordingly; and the potter knows how long he must leave the pots in the fire, so that they are not cracked by staying in it too long or rendered useless by being taken out of it before they are properly fired. If human understanding extends this far, must not God be much more aware, infinitely more aware, of the degree of trial it is right to impose on each soul, so that it become tried and true, fit for the kingdom of heaven?
The most important thing in any good effort and the height of all activities is to persevere in prayer, by means of which we can always acquire through supplication the other virtues from God as well.
Conscience in men is nothing else but the voice of the omnipresent God moving in the hearts of men, as He Who alone Is and has created everything, the Lord knows all as Himself - all the thoughts, desires, intentions, words, and works of men, present, past, and future. However far in front I may let my thoughts, my imagination, run He is there before me and I ever inevitably finish my course in Him, ever having Him as the witness of my ways. 'His eyes are open upon all the ways of the sons of men' (Jer 32:19). 'Whither shall I go from Thy Spirit, or whither shall I flee from Thy presence?' (Ps 139:7).
