The belief in a “divine presence” is a disbelief in the words of Yeshua.
The idea that there are any “priests” is also a disbelief in the Words of Yeshua.
The idea that the Lord’s Supper involved “unlevened bread” is at best a total misunderstanding of the circumstances and timing of the event. The Lord’s supper was not a passover seder, it was on a night of preparation for passover, which was the next evening, after Yeshua had been crucified, the effective sacrifice for all, and his blood poured out onto the mercy seat of the ark in the cavern below.
Faith has to be based on reality, not confusion.
Cor 11:23-29
For I received from the Lord what I also handed on to you, that the Lord Jesus, on the night he was handed over, took bread, and, after he had given thanks, broke it and said, “This is my body that is for you. Do this in remembrance of me.” In the same way also the cup, after supper, saying, “This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.” For as often as you eat this bread and drink the cup, you proclaim the death of the Lord until he comes. Therefore whoever eats the bread or drinks the cup of the Lord unworthily will have to answer for the body and blood of the Lord. A person should examine himself, and so eat the bread and drink the cup. For anyone who eats and drinks without discerning the body, eats and drinks judgment on himself.
Mk 14:22-24
While they were eating, he took bread, said the blessing, broke it, and gave it to them, and said, “Take it; this is my body.” Then he took a cup, gave thanks, and gave it to them, and they all drank from it. He said to them, “This is my blood of the covenant, which will be shed for many.”
Mt 26:26-28
While they were eating, Jesus took bread, said the blessing, broke it, and giving it to his disciples said, “Take and eat; this is my body.” Then he took a cup, gave thanks, and gave it to them, saying, “Drink from it, all of you, for this is my blood of the covenant, which will be shed on behalf of many for the forgiveness of sins.”
Lk 22:15-20
He (Jesus) said to them, “I have eagerly desired to eat this Passover with you before I suffer, for, I tell you, I shall not eat it (again) until there is fulfillment in the kingdom of God.” Then he took a cup, gave thanks, and said, “Take this and share it among yourselves; for I tell you (that) from this time on I shall not drink of the fruit of the vine until the kingdom of God comes.” Then he took the bread, said the blessing, broke it, and gave it to them, saying, “This is my body, which will be given for you; do this in memory of me.” And likewise the cup after they had eaten, saying, “This cup is the new covenant in my blood, which will be shed for you.”
Jn 6:53-56
Jesus said to them, “Amen, amen, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you do not have life within you. Whoever eats my flesh and drinks my blood has eternal life, and I will raise him on the last day. For my flesh is true food, and my blood is true drink. Whoever eats my flesh and drinks my blood remains in me and I in him.”
Jn 6:51
I am the living bread that came down from heaven; whoever eats this bread will live forever; and the bread that I will give is my flesh for the life of the world.
Jn 6:53
Amen, amen, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you do not have life within you.
Jn 6:54

Jn 6:55
For my flesh is true food, and my blood is true drink.
Jn 6:56

Jn 6:60,66
Then many of his disciples who were listening said, “This saying is hard; who can accept it?” ... As a result of this, many (of) his disciples returned to their former way of life and no longer accompanied him.
