No conditions were added, no ‘confession’ requred, no limitations applied excluding those who have sinned.
St Paul disagrees with you and he was instructed by Christ Himself.
1 Cor 11:27 Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be answerable for the body and blood of the Lord. 28 Examine yourselves, and only then eat of the bread and drink of the cup. 29 For all who eat and drink without discerning the body, eat and drink judgment against themselves. 30 For this reason many of you are weak and ill, and some have died. 31 But if we judged ourselves, we would not be judged. 32 But when we are judged by the Lord, we are disciplined so that we may not be condemned along with the world.
33 So then, my brothers and sisters, when you come together to eat, wait for one another. 34 If you are hungry, eat at home, so that when you come together, it will not be for your condemnation. About the other things I will give instructions when I come.
The context has them not “discerning the body” by gluttoning, getting drunk and missing the purpose of the meal. The warning to examine cannot be teased out into other sins.
Also, where is the attendant judgment today? Where is the DEATH, i.e. “falling asleep”? Should be dropping like flies!
Lots of things we find in the early church period are missing today, and it has nothing to do with us. Nothing. The Corinthians were a mess and had full operation of the sign gifts. FULL! Despite their sins.
Lots of ginning up in the flesh goes on to duplicate eras that are not ours today.
Read verse 28 again: “28 Examine yourselves, and only then eat of the bread and drink of the cup.” It says: “Examine yourselves”. It doesn’t say let your Bishop examine you, or let your Deacon examine you, it says “Examine yourselves”. So, since the judgement that will be meted out is a personal one, the decision to eat the bread and to drink from the cup is a personal decision.
