It also brings eternal torment on that day when the Lord will render to each according to his works (Rom 2:6). The Master of all Himself explained this when He said, "Then you will begin to say: We ate and drank before Thee, and Thou didst teach in our streets.
"And He will say, I tell you, I do not know where you are from. Depart from Me, all you workers of unrighteousness" (Lk 13:26-27).
Since such and so great a punishment lies before those who partake unworthily of the dread Mysteries of Christ, the God-speaking Paul handed down to us this commandment: "Let a man examine himself, and so let him eat of the bread and drink of the cup" (1 Cor 11:28).
Do you hear? Wisdom and understanding appoint you judge over yourself. Why? For what man knows the things of a man except the spirit of the man that is in him (1 Cor 2:11)?
What other man knows the secrets of your heart better than your own spirit and your own conscience?
Therefore, before you approach the Mysteries, examine yourself. Search your deeds. If you find in them transgression of God’s commandments and your will remains uncorrected, then refrain.
For if you partake, you will be guilty of the Body and Blood of the Lord (1 Cor 11:27).
Attend to your words. If you learn that your mouth has multiplied malice and your tongue has woven deceits, and that sitting against your brother you slandered him and set a stumbling block against your mother’s son (Ps 49:19-20), then refrain.
If deceit, false witness, betrayal, and impenitence remain in you, refrain. For you will eat and drink unworthily and will be guilty of the Body and Blood of the Lord.
Examine your thoughts. If you notice pride in your mind, envy in your soul, enmity in your heart, and no repentance, then refrain. For if you partake, you eat and drink judgment to yourself.
This Mystery is most holy, and therefore those who approach it must be holy. For this reason, when the time of divine communion draws near, the priest proclaims, "The Holy Things are for the holy."
But who is holy? Who will be clean from defilement? No one, even if his life on earth lasts but one day (Jn 14:4-5).
What then remains to be done? Is it better not to approach the Mystery, so as not to fall under accusation and judgment? May this not be.
Communion in the divine Eucharist is necessary for the strengthening of faith, for the practice of virtue, and for the perfection of life. Without communion in the Body and Blood of the Lord, it is impossible to inherit eternal life.
"Amen, amen, I say to you: unless you eat the Flesh of the Son of Man and drink His Blood, you have no life in yourselves" (Jn 6:53).
But you say, "I see myself constrained on both sides. If I partake unworthily, I sin. If I do not partake at all, I will be guilty of torment. Therefore I do not know what to do."
Do a third thing, brother: partake worthily. But how, since you are a sinner? In the way God prescribed to you through the Prophet Moses and through the Apostle Paul.
Paul commands you first to examine yourself. That is, look into all your sins. Seeing the multitude of your transgressions, and also considering for your salvation the need for communion, do not doze or sleep.
Do not remain lying in the mire of your sins. "Awake, you who sleep, and arise from the dead, and Christ will give you light" (Eph 5:14).
Do what God commanded you through Moses: cleanse yourself. This means: repent like Manasseh, abandon iniquity like Zacchaeus, and resolve to live pleasingly to God like Matthew.
Cleanse yourself. That is, come to the judgment seat of your spiritual father. With humility like the sinful woman, and with contrition like the thief, confess all your sins.
Repentance, conversion, complete abstinence from sin, and confession will blot out your transgressions and cleanse you from all your sins.
"I acknowledged my iniquity, and I did not hide my sin. I said, I will confess my iniquity against myself to the Lord; and Thou forgavest the ungodliness of my heart" (Ps 31:5).
Like Peter, wash not your garments, but the defilement of your soul, mind, and heart with your bitter tears.
At least for three days prepare yourself by prayer, fasting, almsgiving, and every other work pleasing to God.
Then approach with faith and reverence, with fear and trembling, beating your breast like the publican and crying out with the centurion, "Lord, I am not worthy that Thou shouldest come under my roof" (Mt 8:8).
And so partake of the heavenly Mysteries of Christ. In this way communion will become for you sanctification of soul and body, and perfect union with God.
Then you will become unconquerable by the passions, terrible to demons, a friend of the angels, a son of God, and an heir of His heavenly Kingdom. Amen.
