They (namely the Apostles) have not handed down everything in writing, but have also delivered many things in unwritten form. The former and the latter are equally trustworthy, and so we also consider the [unwritten] Tradition of the Church to be trustworthy. Is it Tradition? Seek no further.
Monasticism itself is a perpetual labor of conquering passions and uprooting them in order that, being in a pure and immaculate state, one may preserve oneself before the face of God. This, then, is your task! Give your attention to it, and direct all your powers towards it.
Let us then not lose heart, nor be slothful or timid in prayer. Even if we have been brought down to the depths of evil, prayer can speedily draw us back.
Let each one consider within himself what faults he must remedy in himself, what good work he may yet do, what sin he may wipe out from his soul, so that by this he may become better. And if he finds that he has made progress in this excellent market, through fasting, and is aware that there is need for much care for his wounds, then let him draw near. If however he remains neglectful of himself, and has only his fasting to show, and makes no progress in other directions, then let him remain outside, and let him return only when all his sins are cleansed.
Do you wish to honor the Body of the Savior? Do not despise it when it is naked. Do not honor it in church with silk vestments while outside it is naked and numb with cold. He who said, 'This is my body,' and made it so by his word, is the same that said, 'You saw me hungry and you gave me no food. As you did it not to the least of these, you did it not to me.' Honor him then by sharing your property with the poor. For what God needs is not golden chalices but golden souls.
What does it mean to be as wise as a serpent? When a serpent is attacked, it is willing to have much of its body severed, as long as it saves the head. So to be wise as a serpent means to be willing to lose everything - your wealth, your reputation, your friends - as long as you save your faith. Your faith is your head, by which you learn all truth; and by that truth your soul is set free. We should, however, recognize that the wisdom of the serpent is not enough; we must be honest and innocent as doves. Indeed it is the combination of wisdom and innocence that creates virtue. The person who is wise as a serpent can sustain the most terrible attacks and still continue to flourish as a disciple of Christ. The person who is innocent refuses to retaliate against those who make the attacks. To be as innocent as a dove means never to take revenge on those who wrong you or undermine you. Unless wisdom is tempered by innocence, one attack provokes another, and conflict continues without end. Unless innocence is tempered by wisdom, a person is so vulnerable that he will not even survive a single attack. Rest assured that no one can ever take away your faith; your wisdom guards against that. But be careful never to bear a grudge against anyone who does you wrong.
Why do you beat the air and run in vain? Every occupation has a purpose, obviously. Tell me then, what is the purpose of all the activity of the world? Answer, I challenge you! It is vanity of vanity: all is vanity.
In the matter of piety, poverty serves us better than wealth, and work better than idleness, especially since wealth becomes an obstacle even for those who do not devote themselves to it. Yet, when we must put aside our wrath, quench our envy, soften our anger, offer our prayers, and show a disposition which is reasonable, mild, kindly, and loving, how could poverty stand in our way? For we accomplish these things not by spending money but by making the correct choice. Almsgiving above all else requires money, but even this shines with a brighter luster when the alms are given from our poverty. The widow who paid in the two mites was poorer than any human, but she outdid them all.
Whenever we enter the church and draw near to the heavenly mysteries, we ought to approach with all humility and fear, both because of the presence of the angelic powers and out of the reverence due to the sacred oblation; for as the Angels are said to have stood by the Lord's body when it lay in the tomb, so we must believe that they are present in the celebration of the Mysteries of His most sacred Body at the time of consecration.
A brother who shared a lodging with other brothers asked Abba Bessarion, 'What should I do?' The old man replied, 'Keep silence and do not compare yourself with others.'
Receive me today, O Son of God, as a partaker of Thy mystical Supper; for I shall not speak of Thy mystery to Thine enemies, neither give Thee a kiss as did Judas. But like a thief, I shall confess Thee. Remember me, O Lord, when Thou comest into Thy kingdom.
We cannot be saved by seeking just our own individual salvation; we need to look first to the good of others. In warfare, the soldier who takes to flight to save his own skin brings disaster on himself as well as on the others, whereas the good soldier who takes up arms on behalf of his comrades saves his own life along with theirs.
When He had fasted for forty days and for forty nights, and afterwards was hungry, He gave an opportunity to the devil to draw near, so that He might teach us through this encounter how we are to overcome and defeat him.
