A common mistake made by Christians of all stripes is supposing that 'Bread and Wine' are a new thing - The Jews have been keeping 'communion' for millennia, long before Christians. The ceremonial prayers (actually two, one for bread and one for wine), a remembrance of Melchizedek and of Abraham, were what Yeshua was performing - What is important is not the ceremonial prayers He performed, but rather, the revelation he announced thereby:
'Blessed are you, oh YHWH, Creator of the universe, who brings forth bread from the earth'...
This is my body, broken for you...
'Blessed are you, oh YHWH, Creator of the universe, who brings forth fruit from the vine'...
This is my blood, which is shed for you...
This is an institution of the Order of Melchizedek being revealed... HE is the BREAD brought forth from the earth. HE is the VINE. This is BIG-TIME Abrahamic Covenant stuff.
The same with Baptism - Look to the Hebrew mikvah to find it's true root.
The same with marriage - look to the Hebrew marriage to understand your marriage covenant and betrothal.
The reason I argue that the issue can be a semantical one is this, several definitions for the word "sacrament" exist, and one's definition definitely defines one's position on the matter.
Again, it is incidental to my argument. It is the actual images portrayed by these sacraments or symbols which are corrupted - It depends upon what a baptism IS... What communion IS... What they look like, what they are for. If the picture is wrong, one can try to explain it and lend attributes to it until the cows come home, and you will get nowhere.
Can you provide a source for this? Are these the prayers that were offered during the Passover?
It seems plain enough to me that Jesus was telling his disciples to take the bread and wine in remembrance of his death, a "New Covenant" in his blood.
Luke 22:14 When the hour came, Jesus and his apostles reclined at the table.
15 And he said to them, “I have eagerly desired to eat this Passover with you before I suffer.
16 For I tell you, I will not eat it again until it finds fulfillment in the kingdom of God.”
17 After taking the cup, he gave thanks and said, “Take this and divide it among you.
18 For I tell you I will not drink again from the fruit of the vine until the kingdom of God comes.”
19 And he took bread, gave thanks and broke it, and gave it to them, saying, “This is my body given for you; do this in remembrance of me.”
20 In the same way, after the supper he took the cup, saying, “This cup is the new covenant in my blood, which is poured out for you.
