1 Corinthians 11:29

We also, our Father, thank You for the precious blood of Jesus Christ, which was shed for us and for His precious body, whereof we celebrate this representation, as Himself appointed us, "to show forth His death." [1 Corinthians 11:26] For through Him glory is to be given to You forever. Amen. Let no one eat of these things that is not initiated; but those only who have been baptized into the death of the Lord. But if any one that is not initiated conceal himself, and partake of the same, "he eats eternal damnation;" because, being not of the faith of Christ, he has partaken of such things as it is not lawful for him to partake of, to his own punishment. But if any one is a partaker through ignorance, instruct him quickly, and initiate him, that he may not go out and despise you.

Now concerning the Thanksgiving (Eucharist), thus give thanks. First, concerning the cup: We thank thee, our Father, for the holy vine of David Thy servant, which Thou madest known to us through Jesus Thy Servant; to Thee be the glory for ever. And concerning the broken bread: We thank Thee, our Father, for the life and knowledge which Thou modest known to us through Jesus Thy Servant; to Thee be the glory for ever. Even as this broken bread was scattered over the hills, and was gathered together and became one, so let Thy Church be gathered together from the ends of the earth into Thy kingdom; for Thine is the glory and the power through Jesus Christ for ever. But let no one eat or drink of your Thanksgiving (Eucharist), but they who have been baptized into the name of the Lord; for concerning this also the Lord hath said, Give not that which is holy to the dogs. But after ye are filled, thus give thanks: We thank Thee, holy Father, for Thy holy name which Thou didst cause to tabernacle in our hearts, and for the knowledge and faith and immortality, which Thou modest known to us through Jesus Thy Servant; to Thee be the glory for ever. Thou, Master almighty, didst create all things for Thy name's sake; Thou gavest food and drink to men for enjoyment, that they might give thanks to Thee; but to us Thou didst freely give spiritual food and drink and life eternal through Thy Servant. Before all things we thank Thee that Thou art mighty; to Thee be the glory for ever. Remember, Lord, Thy Church, to deliver it from all evil and to make it perfect in Thy love, and gather it from the four winds, sanctified for Thy kingdom which Thou hast prepared for it; for Thine is the power and the glory for ever. Let grace come, and let this world pass away. Hosanna to the God (Son) of David! If any one is holy, let him come; if any one is not so, let him repent. Maran atha. Amen. […]

"For he that eateth and drinketh unworthily, eateth and drinketh judgment to himself." What sayest thou, tell me? Is this Table which is the cause of so many blessings and teeming with life, become judgment? Not from its own nature, saith he, but from the will of him that approaches. For as His presence, which conveyed to us those great and unutterable blessings, condemned the more them that received it not: so also the Mysteries become provisions of greater punishment to such as partake unworthily. But why doth he eat judgment to himself? "Not discerning the Lord's body:" i.e., not searching, not bearing in mind, as he ought, the greatness of the things set before him; not estimating the weight of the gift. For if thou shouldest come to know accurately Who it is that lies before thee, and Who He is that gives Himself, and to whom, thou wilt need no other argument, but this is enough for thee to use all vigilance; unless thou shouldest be altogether fallen.

In the species of bread and wine Christ is set before us as food, which whoever receives worthily, not only sacramentally, but also eating spiritually through faith and charity, is more fully incorporated into the mystical body of Christ and is in himself refreshed and …

Not because of the nature of the Mysteries (for they are life-giving), but because of the unworthiness of the one who approaches, just as looking at the sun is harmful to diseased eyes. That is, without examining or thinking about the greatness of what is …
