For nothing can so make a man an imitator of Christ as caring for his neighbors. Indeed, even though you fast, or sleep on hard ground, or even suffer unto death, but should take no thought for your neighbor, you have done nothing great; despite what you have done, you will still stand far from this model of a perfect Christian.
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.
The spiritual discipline of fasting is a tool for shifting the focus away from us and toward the Lord and our brothers and sisters in whom we encounter Him each day. If we distort fasting into a private religious accomplishment to prove how holy we are, we would do better not to fast at all. That would simply be a way of serving ourselves instead of God and those who bear His image and likeness. In Lent, our focus must be set squarely on Christ and His living icons, not on us. The fundamental calling of the Christian life is to become like our Lord, Who offered Himself up for the salvation of the world purely out of love. If we are truly in communion with Him, then we too must offer up ourselves for our neighbors. And as He taught in the parable of the Good Samaritan, there are no limits on what it means to be a neighbor to anyone who is in need, regardless of nationality, culture, or anything else. Those who limit their concern for people according to such standards place serving the kingdoms of this world before fidelity to the Kingdom of God.
If it is made possible, I intend to come to you in order to see the faithful gathered in Jerusalem, and especially the Mother of Jesus: they say of her that she is honorable, affable, and arouses wonder in all, and all wish to see her. But who would not wish to see the Virgin and to converse with her who bore the true God? ...With us she is glorified as the Mother of God and the Virgin full of grace and virtue. They say of her that she is joyful in troubles and persecutions, does not grieve in poverty and want, and not only does not get angry with those who offend her but does good to them still more... All who see her are delighted.
Let us therefore show honor and respect, not alone to those that are older than us, but also our equals. For it is no humility to do what you ought to do, or are compelled to do: that is not humility, but duty. It is true humility to give way to those who are seen to be less than us. And if we are truly wise, we shall consider no one as less than ourselves, but all men as our superiors.
When day is done, let us give thanks both for what we have received throughout the day, and for what we have done rightly; and let us make confession of what we have not done, and of every sin, voluntary, or involuntary or even hidden from us, in word or in deed and even in our heart, that we may bring upon us God's mercy for all of them. For to examine ourselves upon what we have done is a great help against falling into the same sins again. The things you say in your hearts, be sorry for them upon your beds (Ps. iv. 5).
For the Antichrist will come for the destruction of men, and to injure them, for what will he not then work? He will change and confound all things, both by his commandments and by the fear of him. He will be terrible in every way: by his power and by his unlawful commandments.’
A monk is he who wants to sleep and does not sleep, who wants to eat and does not eat, who wants to drink and does not drink. A monk is distinguished by ‘continual forcing of nature.’
I have said these things, not that we may disparage fasting, but that we may honor fasting; for the honor of fasting consists not in abstinence from food, but in withdrawing from sinful practices; since he who limits his fasting only to an abstinence from meats, is one who especially disparages it. Dost thou fast? Give me proof of it by thy works! Is it said by what kind of works? If thou seest a poor man, take pity on him! If thou seest an enemy, be reconciled to him! If thou seest a friend gaining honor, envy him not! If thou seest a handsome woman, pass her by! For let not the mouth only fast, but also the eye, and ear, and the feet, and the hands, and all the members of our bodies. Let the hands fast, by being pure from rapine and avarice. Let the feet fast, by ceasing from running to the unlawful spectacles. Let the eyes fast, being taught never to fix themselves rudely upon handsome countenances, or to busy themselves with strange beauties. For looking is the food of the eyes, but if this be such as is unlawful or forbidden, it mars the fast; and upsets the whole safety of the soul; but if it be lawful and safe, it adorns fasting. For it would be among things the most absurd to abstain from lawful food because of the fast, but with the eyes to touch even what is forbidden. Dost thou not eat flesh? Feed not upon lasciviousness by means of the eyes. Let the ear fast also. The fasting of the ear consists in refusing to receive evil speakings and calumnies. 'Thou shalt not receive a false report,' it says.
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.
