Let's look at a review by an attendee of the moment from a later time and let your mind absorb the meaning given in the first paragraph then, look for the answer you seek in the second;
17Now in this that
I declare unto you I praise you not, that ye come together not for the better, but for the worse. 18For first of all, when ye come together in the church, I hear that there be divisions among you; and I partly believe it.
19For there must be also heresies among you, that they which are approved may be made manifest among you.
20When ye come together therefore into one place, this is not to eat the Lord's supper. 21For in eating every one taketh before
other his own supper: and one is hungry, and another is drunken.
22What? have ye not houses to eat and to drink in? or despise ye the church of God, and shame them that have not? What shall I say to you? shall I praise you in this? I praise
you not.
23For I have received of the Lord that which also I delivered unto you, That the Lord Jesus the
same night in which he was betrayed took bread:
24And when he had given thanks, he brake
it, and said,
Take, eat: this is my body, which is broken for you: this do in remembrance of me.
25After 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.
26For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come.
Now let us go back in time.....
Exodus 12:1 And the Lord spake unto Moses and Aaron in the land of Egypt saying, 2 This month shall be unto you
the beginning of months: it shall be the first month of the year to you. 3 Speak ye unto all the congregation of Israel, saying, In the tenth day of this month they shall take to them every man a lamb, according to the house of their fathers, a lamb for an house: 4 And if the household be too little for the lamb, let him and his neighbour next unto his house take it according to the number of the souls; every man according to his eating shall make your count for the lamb. 5
Your lamb shall be without blemish, a male of the first year: ye shall take it out from the sheep, or from the goats:
6 And
ye shall keep it up until the fourteenth day of the same month:
and the whole assembly of the congregation of Israel shall kill it in the evening.
8 And they shall eat the flesh in that night, roast with fire, and unleavened bread; and with bitter herbs they shall eat it. 9 Eat not of it raw, nor sodden at all with water, but roast with fire; his head with his legs, and with the purtenance thereof. 10 And ye shall let nothing of it remain until the morning; and that which remaineth of it until the morning ye shall burn with fire. 11 And thus shall ye eat it; with your loins girded, your shoes on your feet, and your staff in your hand; and ye shall eat it in haste: it is the Lord's passover.
18 In the first month, on the fourteenth day of the month at even, ye shall eat unleavened bread...
The bread without yeast was symbolic of the word of God without the human additives. Christ is the pure doctrine of God without any earthly additives.
Matt 16:6 Then Jesus said unto them, Take heed and beware of the
leaven (yeast) of the Pharisees and of the Sadducees. 7 And they reasoned among themselves, saying, It is because we have taken no bread.
11 How is it that ye do not understand that I spake it not to you concerning bread, that ye should beware of the leaven of the Pharisees and of the Sadducees?
12 Then understood they how that he bade them not beware of
the leaven of bread, but of the doctrine of the Pharisees and of the Sadducees.
GG God has gifted you with a sharp mind and a discerning intellect. If you were one of the goats then you would be just another follower of mans additives... but you question many of the things that don't ring true as you should if a part of you resonates with the Spirit of God that came to you through Adam from The Father of all living.
Read these things and be all God made you to be. Do not listen to man or men... even me. Listen to what the still small voice says through your heart.... and test the spirits... if they do not speak after his word then they are not of God
