The angel who is always near us is by nothing so distressed and made indignant as when, without being constrained by some necessity, we deprive ourselves of the ministration of the Holy Mysteries and of reception of Holy Communion, which grants remission of sins. For at that hour the priest offers up the sacrifice of the Body of Him Who gives us life, and the Holy Spirit descends and consecrates the Body and Blood and grants remission to creation. The Cherubim, the Seraphim, and the angels stand with great awe, fear, and joy. They rejoice over the Holy Mysteries while experiencing inexpressible astonishment. The angel who is always by us is consoled, because he also partakes in that dread spectacle and is not deprived of that perfect intercourse.
When you fail to carry out the divine precepts of faith, your faith is blind. For if the precepts of God are light, it is clear that when you fail to put the divine precepts into practice you are without divine light. You are God's servant merely in name, not in reality.
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.
When you close the doors to your dwelling and are alone you should know that there is present with you the angel whom God has appointed for each man...This angel, who is sleepless and cannot be deceived, is always present with you; he sees all things and is not hindered by darkness. You should know, too, that with him is God, who is in every place; for there is no place and nothing material in which God is not, since He is greater than all things and holds all men in His hand.
There is one method which, if practiced with full attention, will seldom allow anything passionate to slip unnoticed into the heart. This is to examine our thoughts and feelings, so as to discover which they tend: towards pleasing God or towards pleasing ourselves.
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 (Matt. 5:16). But true glorification of God is possible only if one rightly believes and expresses his right belief in words and deeds.
In the evening, on going to sleep (an image of death for the life of that day); examine your actions during the day that has passed. Such an examination is not difficult for one who leads an attentive life, because attention destroys that forgetfulness which is so characteristic of a distracted person. And thus, recalling all your sins in deed, word, thought and feeling, offer repentance over them to God with the disposition and heartfelt promise of correction.
In the presence of an invisible spirit, the body becomes afraid; but in the presence of an angel, the soul of the humble is filled with joy. Therefore, when we recognize the presence from the effect, let us quickly hasten to prayer, for our good guardian has come to pray with us.
A true Christian is made by faith and love toward Christ. Our sins do not in the least hinder our Christianity, according to the word of the Savior Himself. He deigned to say: not the righteous have I come to call, but sinners to salvation; there is more joy in heaven over one who repents then over ninety righteous ones. Likewise concerning the sinful woman who touched His feet, He deigned to say to the Pharisee Simon: to one who has love, a great debt is forgiven, but from one who has no love, even a small debt will be demanded. From these judgments a Christian should bring himself to hope and joy, and not in the least accept an inflicted despair. Here one needs the shield of faith.
The Christian ought not to be of doubtful mind, nor by anything drawn away from the recollection of God and of His purposes and judgments. The Christian ought in all things to become superior to the righteousness existing under the law, and neither swear nor lie. The Christian ought to be patient, whatever he has to suffer, and to convict the wrong-doer in season, not with the desire of his own vindication, but of his brother's reformation, according to the commandment of the Lord.
Do not be surprised that you fall every day, do not give up, but stand your ground courageously. And assuredly, the angel who guards you will honor your patience. While a wound is still fresh and warm, it is easy to heal; but old, neglected and festering ones are hard to cure, and require for their care much treatment, cutting, plastering and cauterization. Many from long neglect become incurable, but with God all things are possible.
If some Christians cannot comprehend our Orthodox faith, its Sacraments, it proves that the minds and hearts of such persons are too impure and passionate to bear its purity and brightness, just as sick eyes cannot bear the light of the sun. This heavenly treasure can only be comprehended by the hearts of those who free their minds and feelings from worldly attachments.
I am a Christian, you say, and content yourself with this. This is the first deceit - transferring to yourself the privileges and promise of Christianity, without any care to root true Christianity into yourself; or to ascribe to yourself that which can only be acquired by your strength and inner worthiness. Explain to yourself that it is illusory to hope in a name, that God can raise a son of Abraham from a stone and can take away your promise at any time if the conditions for participating in them are not soon fulfilled. Mainly, clarify to yourself what it means to be a Christian, unite yourself to this ideal, and you will see just how stable is this buttress to your blindness.
