Better brush up on your reading of St. Paul's epistles before you try and pass yourself off as an authority on Scripture, again.
"And giving thanks, broke, and said: Take ye, and eat: this is My body, which shall be delivered for you: this do for the commemoration of Me. In like manner also the chalice, after He had supped, saying: This chalice is the new testament in My blood: this do ye, as often as you shall drink, for the commemoration of Me. For as often as you shall eat this bread, and drink the chalice, you shall shew(that means proclaim for those of you who were educated in an outcome based curriculum) the death of the Lord, until He come. 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. But let a man prove himself: and so let him eat of that bread, and drink of the chalice. For he that eateth and drinketh unworthily, eateth and drinketh judgment to himself, not discerning the body of the Lord. Therefore are there many inform and weak among you, and many sleep." 1 Corinthians 11:24-30
Shew is translated from the Greek word artos a masculine noun,and in other translations is "show" - the Israelites made it in the form of an oblong or round cake, as thick as one’s thumb, and as large as a plate or platter hence it was not to be cut but broken. It again, is a sign or picture of the death of Christ.
Further - what was this "sign" to signify? It was to serve as a reminder of what Christ had done - until His return (which hasn't happened yet). We are to commemorate Christ's payment for sin each time we celebrate the Lord's Supper.
And the last section you pasted - For he that eateth and drinketh unworthily - drinks and eats judgment unto themselves. A better (accuracy from the Greek) would be:
For anyone who eats and drinks without discerning the body eats and drinks judgment on himself. That is why many of you are weak and ill, and some have died.
And let us not leave out the context of 1 Corinthians 11 - and what the focus of this section was - The church at Corinth had become very polarized into what we today would call "cliques". When they would gather for the Lord's Supper (remember, in that time, they didn't have a formal "ceremony", it was "whenever they gathered together". This does not imply that they had the Lord's Supper every "Sunday" or worship day. Remember, for the entire congregation to come together in a local church at that time was not always an easy feat. Some would have to travel, weather, and other responsibilities and such prevented them all from coming together as one body, but I digress...
Anyway. This church had basically broken into the "haves" and the "have-nots". Those with money and riches were bringing their own "feast" for the Lord's Supper, while the poor arrived with little or nothing. And each group was eating and drinking on their own. This was not in the spirit that Christ intended and Paul was preaching against that practice - calling for each to come together.
Remember - the "Last Supper" - the event that serves as an example for celebrating the Lord's Supper, was at the conclusion of a fellowship meal - not of a "church service". Does this preclude having the Lord's Supper in conjunction with a regular service? - not at all. But again, look at the example.
And Christ's own words speak to this all being done IN REMEMBRANCE - not as a renewed sacrifice. But if we participate - and yet we are unworthy (definitely does not mean perfect, as none are righteous - period), but indicates one's heart towards the Lord and his fellow brothers and sisters in Christ.
This is somewhat akin to calling oneself a Christian, while blaspheming God at every turn. Wearing the title unworthily (without being a "born-again" believer in Jesus Christ" is dangerous. But again, I somewhat digress.
And far be it for me to lay ANY claim to being an authority on Scripture. A student of the Scriptures? Yes. Someone who takes study and prayer seriously? Yes. A seminarian? Yes. But I will never lay claim to being an expert or an authority, regardless of how much education I receive.
What I do know - I will never place my faith and trust in anything a human being can do or claims to be able to do. My faith and trust are completely and totally 100% in the redeeming work already accomplished by Jesus Christ in that once and for all sacrifice on the cross - His death, burial, and resurrection (which is part of what scriptural water baptism demonstrates...fodder for yet another debate), His continued work towards sanctification in my life, and the eternity He has for me in HIS Heaven.
