Jesus, the Son of God and Second Person of the Trinity, humbles Himself to enter into us under the form of bread and wine. His Body and Blood are adored and received by the faithful, who are transformed by grace into living images of Jesus.
Receiving Communion while in the state of mortal sin, without regular confession and firm purpose of amending one's sinful habits or actions contrary to the Church's teaching, without observing the fast (which includes chewing gum in the Communion line) - all these bring condemnation upon us for they mean we are receiving Christ unworthily.
May we prepare ourselves well before every Mass we attend so that we may confidently access the treasury of grace with humility, professing that Christ is Lord and He is truly present in the Eucharist out of love for us poor sinners.
These prayers can be memorized or written on a note card. Then, we can say them as we approach the altar to receive the Lord. Praying one of these prayers privately will enhance and deepen our communal recitation of the words "Lord, I am not worthy that you should enter under my roof. Only say the word and I shall be healed." We can then cultivate a serious devotion to the precise moment when we commune with the Lord in the Mass.
How shall I, who am unworthy, enter into the splendor of Your saints? If I dare to enter into the bridal chamber, my clothing will accuse me, since it is not a wedding garment; and being bound up, I shall be cast out by the angels. In Your love, Lord, cleanse my soul and save me.
Loving Master, Lord Jesus Christ, my God, let not these holy Gifts be to my condemnation because of my unworthiness, but for the cleansing and sanctification of soul and body and the pledge of the future life and kingdom. It is good for me to cling to God and to place in Him the hope of my salvation.
Receive me today, Son of God, as a partaker of Your mystical Supper. I will not reveal Your mystery to Your adversaries. Nor will I give You a kiss as did Judas. But as the thief I confess to You: Lord, remember me in Your Kingdom.
