Luke 22:15 And he said unto them, With desire I have desired to eat this passover with you before I suffer: 16 For I say unto you, I will not any more eat thereof, until it be fulfilled in the kingdom of God.
|Mark 14:22 And as they did eat, Jesus took bread, and blessed, and brake it, and gave to them, and said, Take, eat: this is my body.||Matt 26:26 And as they were eating, Jesus took bread, and blessed it, and brake it, and gave it to the disciples, and said, Take, eat; this is my body.||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 .|
|Mark 14:23 And he took the cup, and when he had given thanks, he gave it to them: and they all drank of it.||Matt 26:27 And he took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it;||Luke 22:17 And he took the cup, and gave thanks, and said, Take this, and divide it among yourselves:|
|Mark 14:24 And he said unto them, This is my blood of the new testament , which is shed for many.||Matt 26:28 For this is my blood of the new testament, which is shed for many for the remission of sins.||Luke 22:20  Likewise also the cup after supper , saying, This cup is the new testament in my blood, which is shed for you.|
|Mark 14:25 Verily I say unto you, I will drink no more of the fruit of the vine, until that day that I drink it new in the kingdom of God.||Matt 26:29 But I say unto you, I will not drink henceforth of this fruit of the vine, until that day when I drink it new with you in my Father's kingdom.||Luke 22:18 For I say unto you, I will not drink of the fruit of the vine, until the kingdom of God shall come.|
John 13:31  Therefore, when he [Judas] was gone out, Jesus said, Now is the Son of man glorified, and God is glorified in him. 32 If God be glorified in him, God shall also glorify him in himself, and shall straightway glorify him. 33 Little children, yet a little while I am with you. Ye shall seek me: and as I said unto the Jews, Whither I go, ye cannot come; so now I say to you. 34 A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. 35 By this shall all men know that ye are my disciples, if ye have love one to another.
In Luke, Jesus drinks wine before eating brea -- the opposite order from Mark and Matthew.
Jesus' words in Luke's text agree with those in the account of the last supper in 1 Corinthians, but has the order of bread and wine reversed. 1 Corinthians 11:23 For 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: 24 And 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. 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.
The "new testament" may refer to Jeremiah 31:31 Behold, the days come, saith the Lord, that I will make a new covenant with the house of Israel, and with the house of Judah.
In Luke, this is a second drink from the cup before Jesus reveals that he is to be betrayed.
Note that Luke refers to two cups where Mark and Matthew mention only one.
John places this conversation after the last supper but before Jesus and the disciples leave the room. It cannot be reconciled with Mark and Matthew.
