The
New Testament (Covenant) was instituted by Jesus Christ in the Upper Room...
Matthew 26:26-28 ---> "Now as they were eating, Jesus took bread, and after blessing it broke it and gave it to the disciples, and said, 'Take, eat; this is my body.' And he took a cup, and when he had given thanks he gave it to them, saying, '
Drink of it, all of you, for this is my blood of the covenant, which is poured out for many for the forgiveness of sins.'"
Mark 14:22-24 ---> "And as they were eating, he took bread, and after blessing it broke it and gave it to them, and said, 'Take; this is my body.' And he took a cup, and when he had given thanks he gave it to them, and they all drank of it. And he said to them,
'This is my blood of the covenant, which is poured out for many.'"
Luke 22:19-22 ---> "And he took bread, and when he had given thanks, he broke it and gave it to them, saying, 'This is my body, which is given for you. Do this in remembrance of me' And likewise the cup after they had eaten, saying, '
This cup that is poured out for you is the new covenant in my blood.'"
Here is Paul quoting Jesus in 1 Cor 11;23-25 ---> "For I received from the Lord what I also handed on to you, that the Lord Jesus on the night when he was betrayed took a loaf of bread, and when he had given thanks, he broke it and said, 'This is my body that is for you. Do this in remembrance of me.' In the same way he took the cup also, after supper, saying, '
This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.'”
The reason why the collection of books in the New Testament is called the “New Testament” is because those writings, along with commemorations of the saints and martyrs, were read when Christians gathered to celebrate the “New Testament”, that is,
the Eucharist.
If you have no Eucharist, you have no Church because the Church cannot exist without the Eucharist; nor can the Eucharist exist without the Church. Thus when you reject not only the reality of the Eucharist, which God's presence among His people - Emmanuel, you also reject the reality of the Church and replace it with an "invisible, pneumatic" sect of disjointed believers of various and differing creeds.
No Eucharist = No Church
