Trials are of two kinds. Either affliction will test our souls as gold is tried in a furnace, and make trial of us through patience, or the very prosperity of our lives will oftentimes, for many, be itself an occasion of trial and temptation. For it is equally difficult to keep the soul upright and undefeated in the midst of afflictions, as to keep oneself from insolence and pride in prosperity.
One must clean the royal house from every impurity and adorn it with every beauty, then the king may enter into it. In a similar way one must cleanse the earth of the heart and uproot the weeds of sin and the passionate deeds and soften it with sorrows and the narrow way of life, sow in it the seed of virtue, water it with lamentation and tears, and only then does the fruit of dispassion and eternal life grow. For the Holy Spirit does not dwell in a man until he has been cleansed from passions of the soul and body. Only one thing may remain within a man, either the Holy Spirit or the passions. Where the Holy Spirit is, there the passions do not come near, and where the passions are, there the Holy Spirit does not dwell, but rather the evil one.
Of the teachings and proclamations preserved in the Church, some we possess from written teaching, while others we have received in secret from the Tradition of the Apostles; these both have the same validity [ie. authority] for true religion. And no one will deny these points, at least if he is even moderately experienced in Church [matters].
Therefore, if you wish to conquer the passions, cut off the love of pleasure; but if you are pursuing food, you will spend a life in passions; the soul will not be humbled if the flesh is not deprived of bread. It is not possible to deliver the soul from perdition while protecting the body from unpleasantness.
We should indeed be the strangest people if we were to find any pleasure in the schisms and divisions that beset the Church, and if we did not consider it as the greatest achievement to see the scattered limbs of Christ reassembled once more. Our desire to achieve this is as strong as the knowledge of our weakness to do so.
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.
Peter was first given the keys, but then he was allowed to fall into the sin of denying Christ; and so his pride was humbled by his fall. Do not be surprised, then, if after receiving the keys of spiritual knowledge you fall into various evil thoughts. Glorify our Lord, for He alone is wise: through setbacks of this kind He restrains the presumption that we tend to feel because of our advance in the knowledge of God. Trials and temptations are the reins whereby God in His providence restrains our human arrogance.
How are we to come to this saving humility, leaving behind us the deadly swelling of arrogance? By exercising ourselves in it in all things, and by keeping in mind that there is nothing which cannot be a danger to us. For the soul becomes like the things it gives itself to; and takes the character and appearance of what it does. Let your demeanor, your dress, your walking, your sitting down, the nature of your food, the quality of your bed, your house and what it contains aim at simplicity. And let your speech, your singing, your manner with your neighbor, let these things also be more in accord with humility than with vanity. In your words let there be no empty pretence, in your singing no excessive sweetness, in conversation be not ponderous or overbearing. In everything refrain from seeking to appear important. Be a help to your friends, kind to the ones who live with you, gentle to your servant, patient with those who are troublesome, loving towards the lowly, comforting to those in trouble, visiting those in affliction, never despising anyone, gracious in friendship, cheerful in answering others, courteous, approachable to everyone, never speaking your own praises, nor getting others to speak them, never taking part in unbecoming conversation, and concealing where you may whatever gifts you possess.
One cannot approach the knowledge of the truth with a disturbed heart. Therefore we must try to avoid everything that disturbs our heart, that causes forgetfulness, excitement or passion, or that awakens unrest. We must free ourselves as much as possible from all fuss and flutter and ado over vain things. Yes, when we serve the Lord we shall not be troubled about many things, but always keep in mind that one thing is needful (Luke 10:41).
Fasting needn't be limited to abstinence from food alone, because true fasting is departure from evil deeds. Forgive your neighbor any insult, abstain from causing your neighbor offence, abstain from irritation, from senseless sorrows, from fear, wrath, and so on. ‘True fasting is alienation from evil, temperance of the tongue, setting aside of wrath, casting out of lust, idle talk, lies, and oath-breaking’…This is a true and pleasing fast for the Lord. Departing from these vices and from a corrupt state is what comprises a true fast.
Do not say...that one or two books is sufficient for instructing the soul. After all, even the bee collects honey not from one or two flowers only, but from many. Thus also he who reads the books of the Holy Fathers is instructed by one in faith or in right thinking, by another in silence and prayer, by another in obedience and humility and patience, by another in self-reproach and in love for God and neighbor; and, to speak briefly, from many books of the Holy Fathers a man is instructed in life according to the Gospel.
If anyone thinks that he has love but does not have the same love for all, but distinguishes between persons, separating the lowly from the rich, the infirm from the healthy, a sinner from a righteous man, one far off from one near, one who is an enemy from one who loves you, such love is not perfect, but partial. Actual and perfect love consists in considering everyone and loving them equally, both those who love you and those who hate you. Such love, with which mercy is inseparable, is, in brief, a net for all virtues. It embraces and contains all the commandments of God within itself.
