Augustine of Hippo, on 1Cor 11:27

“Therefore whosoever shall eat this bread, or drink the chalice of the Lord unworthily, shall be guilty of the body and of the blood of the Lord.”

“You hold the sacraments in their order. First, after the prayer, you are admonished to lift up your hearts; this befits the members of Christ. For if you have become members of Christ, where is your head? Members have a head. If the head had not gone before, the members would not follow. Where did our head go? What did you recite in the Creed? On the third day, He rose again from the dead, He ascended into heaven, He sits at the right hand of the Father. Therefore, our head is in Heaven. Thus when it is said: Lift up your hearts, you answer: We have them with the Lord. And so that you do not attribute the fact that you have your hearts with the Lord to your own strengths, merits, or labors—for it is a gift of God to have your heart lifted up to Him—the bishop or the priest who offers the sacrifice continues and says—when the people respond: We have them with the Lord—: Let us give thanks to the Lord our God, because we have our hearts with the Lord. Let us give thanks because if he did not give it, we would have our hearts on earth. And you attest by saying: It is right and just, that we should give thanks to Him who made us have our hearts lifted up to our head. Then, after the sanctification of God's sacrifice, because he willed that we ourselves should be his sacrifice—this was shown when the first sacrifice of God was laid down and we—meaning the sign of the reality—which we are; behold where the sanctification has been accomplished, we say the Lord's Prayer, which you have received and rendered. After it has been said: Peace be with you, and the Christians give each other a holy kiss. It is a sign of peace: as the lips show, let it be done in conscience, that is, just as your lips approach your brother's lips, let your heart not depart from his heart. Great indeed are the sacraments and very great indeed. Do you wish to know how they are commended? The Apostle says: Whosoever shall eat of the body of Christ or drink of the cup of the Lord unworthily, shall be guilty of the body and blood of the Lord. What does it mean to receive unworthily? To receive it contemptuously, to receive it scoffingly. Do not make it seem cheap to you, because you see it. What you see passes away, but what is signified, the invisible, does not pass, but remains. Behold, it is received, eaten, consumed. Does the body of Christ perish? Does the Church of Christ perish? Do the members of Christ perish? By no means. Here they are cleansed, there they are crowned. Therefore, what is signified remains, even though that which signifies might seem to pass away.”
