Just as breathing is necessary for life, and just as food is necessary for the sustenance of the body, so is frequent Communion necessary for the life of the soul and for the sustenance of its substance, or rather it is incomparably more necessary.
If Christ is in you through the frequent communion of the Holy Sacrament, then be yourself wholly like unto Christ: meek, humble, long-suffering, full of love, without attachment to earthly things, meditating upon heavenly ones, obedient, reasonable. Have His spirit unfailingly within you.
Those who attend the divine service of the Orthodox Church must bear in mind that its purpose is to prepare us for the joyful service of God in heaven; that in serving God with the body, it is still more necessary to serve God with the soul and a pure heart; that in hearing divine service they must learn to serve God as those saints served him, whose lives, and works of faith, hope and love, we hear of during the service; that God should, above all, be served in deed and truth, and not only by words and the tongue.
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.
The Holy Eucharist is the first, most important, and greatest miracle of Christ. All the other Gospel miracles are secondary. How could we not call the greatest miracle the fact that simple bread and wine were once transformed by the Lord into His very Body and His very Blood, and then have continued to be transformed for nearly two thousand years by the prayers of priests, who are but simple human beings? And what is more, this mystery has continued to effect a miraculous change in those people who communicate of the Divine Mysteries with faith and humility.
Take care never to receive Communion while you have anything against anyone, even if this is only a hostile thought. Not until you have brought about reconciliation through repentance should you communicate, [receive the Mysteries]. But you will learn this, too, through prayer.
God smiles on the compassionate heart. Every time a beggar knocks at your door, try to perceive Christ Himself under the humble disguise. Would you, under any circumstances, let Christ knock in vain? The moral qualities of the individual beggar have nothing to do with it; that is Christ's concern, not yours. Who are you to judge your brother? Christ is using the beggar’s hand and mouth to test your compassion of Himself. Will you fail Him?
The moral character and moral value of man's personality depends most of all on the direction and strength of the will. Of course, everyone understands that for a Christian it is necessary to have first, a strong and decisive will, and second, a will which is firmly directed toward the good of his neighbor, toward the side of good and not evil. How is one to develop a strong will? The answer is simple: above all through the exercise of the will. To do this, as with bodily exercise, it is necessary to begin slowly, little by little. However, having begun to exercise one's will in anything ( e.g., in a constant struggle with one's sinful habits or whims) this work on oneself must never cease. Moreover, a Christian who wishes to strengthen his will, his character, must from the very beginning avoid all dissipation, disorder and inconsistency of behavior. Otherwise, he will be a person without character, unreliable, a reed shaking in the wind, as we read in Holy Scripture.
No one can be saved without the renunciation of his will, even though he might struggle fervently, for our will and our manner are like a bronze wall between us and God.
