Of the beliefs and public doctrines entrusted to the care of the Church, there are some which are based on Scriptural teaching, others which we have received handed down in mystery by the tradition of the Apostles; and in relation to the true religion they both have the same force.
Disciplined piety feeds the soul on holy thoughts. What can be more blessed than to imitate on earth the chorus of the angels; to begin the opening day with prayer, honouring the Creator with hymns and songs; and when the sun is up to turn to work, always accompanied by prayer, and to season one's labours with singing? Cheerfulness and freedom from sorrow are the gifts which the soul received from the singing of hymns.
Concerning fasting, do not grieve, as I have said to you before: God does not demand of anyone labors beyond his strength. And indeed, what is fasting if not a punishment of the body in order to humble a healthy body and make it infirm for passions, according to the word of the Apostle: 'When I am weak, then am I strong' (II Corinthians 12:10).
Patience reigns quietly and fruitfully in the life of the man who does not harm or endanger anyone, who is content with little and is obedient to the commandments of the Heavenly Father.
Solitude offers us an excellent opportunity for calming our passions and giving our reason time to remove them thoroughly from our soul. For just as wild animals can be soothed by being stroked, so all our anger, fear and stress, which poison and disrupt our soul, can be soothed by an atmosphere of peace where the freedom from constant disturbance ensures that our soul can be brought more easily under the power of reason.
You have no peace from thoughts, which impel you to trouble others, and in turn to be troubled by others. But know, my brother, that if we offend by word or deed, we are thereby ourselves offended a hundredfold. Be longsuffering in all things and refrain from letting your own will enter into anything. Carefully examine your thoughts lest they infect your heart with deadly poison (ill temper) and make you take a gnat for a camel, a pebble for a cliff, and lest you become like a man who has a beam in his own eye but beholds the mote in the eye of another.
Give thanks to God for all things, because thanksgiving is intercession before God for our weakness. Judge yourself always and in everything as a sinner and as one seduced - and so God will not judge you; be humble in everything and you will receive grace.
Peace is the beginning of the purification of the soul, the tongue freed from speaking of the things of men, the eyes no longer dwelling on the beauty of bodies and elegance of our surroundings, the hearing not undoing the strength of the soul through listening to melodies that were composed for pleasure, nor through the talk of clever and frivolous men, which more than anything else has power to undo the purpose of the soul. For the mind, when not wasted on outward things, or led astray by the world of the senses, turns itself on itself, and through this ascends to the thought of God, and lit by that inward beauty becomes unmindful even of nature, and no more troubled by anxiety for its food, or with concern for clothing; at rest from earth’s cares, all its zeal is given to gaining the things that are good forever.
I had wasted much of my time and devoted almost all of my youth in acquiring knowledge which now appears as just foolishness before God. Then one day I awoke suddenly, as if from some deep sleep, and saw the intense light of divine truth, and realized the absolute worthlessness of all the wisdom taught by the leaders of this world. I wept many tears for the wretchedness of my life and prayed for some guidance to lead my life to faith. The first thing I did to reform my previous way of life was to mix with the poor...
All other possessions do not really belong to the one who has them or to the one who has acquired them for they are exchanged back and forth like a game of dice. Only virtue among our possessions cannot be taken away, but remains with us when we live and when we die.
If you wish to be delivered from shameful passions, do not behave with anyone familiarly, especially with those toward whom your heart is inclined by a lustful passion; through this you will be delivered also from vainglory. For in vainglory is involved the pleasing of men, in the pleasing of men is involved familiarity of behavior, and familiarity of behavior is the mother of all passions.
The Christian ought not to be of doubtful mind, nor by anything drawn away from the recollection of God and of His purposes and judgments. The Christian ought in all things to become superior to the righteousness existing under the law, and neither swear nor lie. The Christian ought to be patient, whatever he has to suffer, and to convict the wrong-doer in season, not with the desire of his own vindication, but of his brother's reformation, according to the commandment of the Lord.
Be slow and dull to idle talk, but knowing and wise in hearkening to the saving words of the Holy Scriptures. Let the hearing of worldly tales be to you as a bitter taste in your mouth, but the discourse of holy men as a honeycomb (Prov. 16.24). Be eager to imitate men of disciplined habits and do not wait to be taught each thing. Strive to attain to the greater virtues, but do not neglect the lesser ones. Do not make light of a fall even if it be the most venial of faults; rather, be quick to repair it by repentance, although many others may commit a large number of faults, slight and grievous, and remain unrepentant. Judge not the sins of others, for they have a just Judge ‘Who will render every man according to his works’ (Rom. 2.6); but be master of what is your own and lighten your own burden insofar as you have the power, for he who increases his own burden will also carry it. In repentance is salvation, but folly is the death of repentance.
