Continually take careful note of your inner intention: watch carefully which way it inclines, and discover whether it is for God and the sake of goodness itself and the benefit of your soul...
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.
The partaking of food has three degrees: abstinence, adequacy and satiety. To abstain, means to remain a little hungry after eating; to eat adequately, means neither to be hungry, nor weighed down. But eating beyond satiety is the door to belly-madness, through which lust comes in. But you, firm in knowledge, choose what is best for you, according to your powers, without overstepping the limits...
The Lord says: 'In your patience possess ye your souls' (Luke 21:19). He did not say: in your fast or in your vigil. By patience I mean that patience which is of God and is the queen of virtues and the basis of manly valor. It is in itself - peace amid strife, stillness in the midst of storm and an impregnable position for those who have acquired it.
He who wishes to tear up the account of his sins and to be inscribed in the Divine book of the saved, can find for this purpose no better means than obedience.
The principle and source of the virtues is a good disposition of the will, that is to say, an aspiration for goodness and beauty. God is the source and ground of all supernal goodness. Thus the principle of goodness and beauty is faith or, rather, it is Christ, the rock of faith, Who is the principle and foundation of all the virtues. On this rock we stand and on this foundation we build every good thing.
There is no shorter ascent to the royal and Divine mansions...than through subduing the five passions hostile to obedience, namely: disobedience, argumentativeness, self-gratification, self-justification and pernicious high opinion of oneself...Disobedience is the mouth of hell; argumentativeness its tongue, whetted like a sword; self-gratification is its sharp teeth; self-justification its throat; high opinion of oneself, which casts one into hell, is the belching of its all-devouring belly. But he who, through obedience, conquers the first, by one stroke cuts off all the rest and with one stride reaches heaven.
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.
