The Church is unity in Christ, the closest union with Christ of all who rightly believe on Him and love Him, and all their union is through Christ. Now the Church consists of both her earthly and heavenly parts, for the Son of God came to earth and became man that He might lead man into heaven and make him once again a citizen of paradise, returning to him his original condition of sinlessness and wholeness and uniting him unto Himself. This is accomplished by the action of divine grace granted through the Church, but effort is also required from man himself. God saves His fallen creature by His own love for him, but man's love for his Creator is also necessary and without it salvation is impossible for him. Striving toward God and cleaving unto the Lord by its humble love, the human soul obtains power to cleanse itself from sin and to strengthen itself for the struggle to full victory over sin.
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.
In the same way a Christian in the strict sense is he only who confesses the true doctrine of Christ and lives in accordance with it. The designation of a Christian consists in glorifying the Heavenly Father by one's life. Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven (St. Matt. V:16). But true glorification of God is possible only if one rightly believes and expresses his right belief in words and deeds. Therefore true Christianity and it alone may be named 'right-glorifying' (Ortho-doxy). By the word 'Orthodoxy' we confess our firm conviction that it is precisely our Faith that is the true doctrine of Christ. When we call anyone or anything Orthodox, we by this very fact indicate his or its non-counterfeit and uncorrupted Christianity, rejecting at the same time that which falsely appropriates the name of Christ.
Those who meditate unceasingly upon the holy and glorious name [of Jesus] in the depths of their heart can sometimes see the radiance of their own spirit-intelligence. For when the mind is profoundly concentrated on this invocation, we feel experientially how it starts burning off all the layers of dirt that normally suffocates the soul.
An icon is a symbol of the invisible. It depicts not only the outward, visible countenance of the Lord and His saints, but also their inner likeness, their sanctity.
To wage war only with the sins that make their appearance as actual deeds would be just as unsuccessful as cutting down weeds in a garden instead of digging them up at the root and throwing them out. Sins appear as inevitable outgrowths from their roots, the passions of the soul.
Before us lie the paths of two thieves. Which path shall we take? The Cross of the Lord was to the Jews a stumbling block; to the Greeks - that is, to the pagans - it was foolishness: how could anyone bow down before an instrument of humiliation, an instrument of torture? They did not understand that by means of this instrument the Lord saved all mankind from the dominion of the devil, from the dominion of sin, from eternal perdition. For the Jews also, the Cross of the Lord was an offense; they wanted to see their messiah as a king of glory, as an earthly king who would exalt the Jewish race. The Cross on which Christ was crucified was for them a stumbling block; Christ’s crucifixion was perceived as an offense, as something senseless, and yet, as the holy Apostle Paul tells us, this stumbling block unto the Jews, this foolishness unto the Greeks is for us Christ the power of God, and the wisdom of God (I Cor. 1:24). What for some spelled perdition, for others became a source of salvation.
Remember, O my soul, the terrible and frightful wonder: that your Creator for your sake became Man, and deigned to suffer for the sake of your salvation. His angels tremble, the Cherubim are terrified, the Seraphim are in fear, and all the heavenly powers ceaselessly give praise; and you, unfortunate soul, remain in laziness. At least from this time forth arise and do not put off, my beloved soul, holy repentance, contrition of heart and penance for your sins.
Blessed is the Good One Who opens His door to the good that they might enter therein, and also does not lock the door of His goodness to the evil if they are converted. Blessed is He Who grants everyone the means to inherit the heavenly kingdom: the righteous inherit it through good deeds, and sinners through repentance. Blessed is He Who for the sake of sinners gave Himself up to death and revilement, Who suffered humiliation in order to grant sinners life.
Condemn only yourself, and you will not be condemned at His second and awful coming. From your whole heart remit the sins of whoever sins before you, and your Father who is in heaven will remit your sins.
To act 'according to one’s strength' means to use a little less than necessary both of food, and drink, and sleep... As for food, restrain yourself when you wish to eat a little more, and in this way you will always make use of it moderately.
