Yers, I have heard that at least 3,000 times and that is what I used to believe until I started delving into the life and times of the New Testament Church. As I always do, I have read numerous books regarding the subject matter to get a broad overview of the topic. This is what I found out.
1. The NTC would have no concept of eating a piece of bread and drinking a sip of wine. It was always in the context of a meal as the Passover meal was.
2. Do this does not say "do this every Sunday". In fact only one gospel said do this. That means three didn't so it is doubtful that it was said at all.
3. One has to find scripture to support a weekly sip of wine and a piece of bread. So far there is none.
4. The term breaking of bread in middle eastern tradition means a meal. Not a sip of wine or a piece of bread.
5. In middle eastern tradition, a meal always started with the head of the house breaking up a loaf of bread and giving a piece to everyone, hence the term.
6. To invite someone round to break bread, it would be an insult to give them a sip of wine and a piece of bread.
7. Those that say Jesus started communion at the passover meal forget that it was a meal and only held once a year.
8. The passage in Corinthians is mainly about how the believers conducted themselves when they came together for a communal meal.
9. The NTC was noticable for how much they loved one another. How did they do that? One way was they provided a meal every evening for the members who were poor or had not eaten that day. That was known as breaking of bread.
10. Acts 2 tells us that the NTC came together for four things one of which was breakikng of bread and one other was fellowship. They fellowshipped round a meal, prepared and cooked by members of the fellowship. The apostle's teaching was discussed during this time and they also prayed.
11. The sip of wine and the piece of bread came into being when Constantine legalized christianity and made it the national religion of the Roman Empire.
12. So as you can see if you do your homework as I have done, breaking of bread is a meal, not an esoteric bit of bread and a sip of wine.
It's not about the breaking of the bread, a sip of wine or a Passover meal, it's about the symbolism of the bread and the wine, being the bread representing the literal body of Christ that was beaten beyond recognition and torn for us and the blood that ran down from the top of His head to the bottom of the cross as He paid the price for our sin being made the last perfect sacrifice in fulfilling the sacrificial law of the Temple.
Exodus 12:14 And this day shall be unto you for a memorial; and ye shall keep it a feast to the LORD throughout your generations; ye shall keep it a feast by an ordinance for ever.
Exodus Chapter 12 is God's instruction of the Passover feast that throughout all the generations the Jews are to keep as a memorial of the exodus that set them free in Egypt. Under the new dispensation of God's grace, Jesus is our Passover Lamb who made atonement for our sin as a scarified Lamb led to the slaughter. (Do this in remembrance of me).
Only Luke and Paul quoted Jesus saying "do this in remembrance of me", but neither one sat with Jesus at the Passover meal. Paul also wrote, and as often as you eat this bread, and drink this cup, ye do shew the Lord's death till he come. Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord. But let a man examine himself, and so let him eat of that bread, and drink of that cup. For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body, 1 Corinthians 11:26-29.
Luke 22:19 And he took bread, and gave thanks, and brake it, and gave unto them, saying, This is my body which is given for you: this do in remembrance of me.
1Cor 11:25 After the same manner also he took the cup, when he had supped, saying, This cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me.
1Cor 11:26 For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come.
It doesn't matter how often you take of the bread and the wine, but that you do it worthily and in remembrance of what Christ paid for us for the remission of our sins.
