Okay, and here is the bit about the Seder Haggadah (hope I don't derail where you wanted the study to go). It's a Passover feast as outlined by a rabbi from about 170AD. I'm fairly sure much of it actually HAS the traditions followed by Jesus and his disciples.
The way the Passover feast relates is quite interesting... I'm just going to lay out a few snippets of it: I'm using green to indicate the passover rituals/prayers in the Haggadah and red for the Bible verses...
The Blessing of Wine, KADESH
First cup of wine is the cup of blessing. The cup is raised and a prayer is said:
“Blessed are you, O Lord our God, for you created the fruit of the
vine. Blessed are you, O Lord our God, for you choose us for your service and taught us to
know what is freedom and what is slavery. Blessed are you, O Lord our God, for you honor us
by this holy festival. Blessed are you, O Lord our God, for you have
kept us in life and have brought us to this feast of freedom.â€Â
The first cup is drank.
The Washing of the Hands, URCHATZ
Symbolic act of cleansing for a holy occasion.
(Jesus) got up from the meal, took off his outer clothing, and wrapped a towel around his waist. After that, he poured water into a basin and began to wash his disciples' feet, drying them with the towel that was wrapped around him.
He came to Simon Peter, who said to him, "Lord, are you going to wash my feet?"
Jesus replied, "You do not realize now what I am doing, but later you will understand."
"No," said Peter, "you shall never wash my feet."
Jesus answered, "Unless I wash you, you have no part with me."
"Then, Lord," Simon Peter replied, "not just my feet but my hands and my head as well!"
Jesus answered, "A person who has had a bath needs only to wash his feet; his whole body is clean. And you are clean, though not every one of you." For he knew who was going to betray him, and that was why he said not every one was clean.
When he had finished washing their feet, he put on his clothes and returned to his place. "Do you understand what I have done for you?" he asked them. "You call me 'Teacher' and 'Lord,' and rightly so, for that is what I am. Now that I, your Lord and Teacher, have washed your feet, you also should wash one another's feet. I have set you an example that you should do as I have done for you. I tell you the truth, no servant is greater than his master, nor is a messenger greater than the one who sent him. Now that you know these things, you will be blessed if you do them. John 13:4-17
Second Cup of Wine: The Cup of Deliverance
Reading of Psalm 114 and a prayer:
“Blessed are you, O Lord our God, who redeemed our ancestors from Egypt and brought us here to this celebration. May it be your will, O God, to give us life and bring us in peace to many more festivals, holy days, and celebrations. May those times inspire us to rebuild the land of Israel, restore the city of Jerusalem, and cause your people everywhere to draw closer to your service. Then we give you thanks with a new song for our freedom. Blessed are you, O Lord our God, who created the fruit of the vine.â€Â
After taking the cup, he gave thanks and said, “Take this and divide it among you. For I tell you I will not drink again of the fruit of the vine until the kingdom of God comes. Luke 22:17-18
Blessing over the MATZAH(Bread),
“Blessed are you, O Lord our God, who brings forth bread from the earth. Blessed are you, O Lord our God, you make us holy by your commandments and command us to eat matzah.â€Â
The matzah is broken and given to all.
And Jesus took bread, gave thanks and broke it, saying, “This is my body given for you; do this in remembrance of me.â€ÂLuke 22:19
Eating of the Bitter Herb, MAROR
We now eat the maror. Thus we remember how bitter is slavery. Blessed are you, O Lord our God, you make us holy by your commandments and command to eat the bitter herbs. Numbers 9:11
The Matzah is broken, given to all and dipped in a bitter herb.
Jesus foresees a bitter betrayal:
Jesus said, “I tell you the truth, one of you will betray me – one who is eating with me.†They were saddened and one by one they said to him, “Surely not I?â€Â
“It is one of the Twelve†he replied, “one who dips bread into the bowl with me. The Son of Man will go just as it is written about him. But woe to that man who betrays the Son of Man! It would be better for him if he had not been born†Mark 14:20-21, John 13:21-30
Passover Lamb, PESACH:
The Pesach, the sacrificial lamb, is the last food to be eaten. It is the dessert or “that which comes lastâ€Â. It reminds us that the Lord passed over the homes of the Jews and saved the firstborn from death.
John saw Jesus coming toward him and said, "Look, the Lamb of God, who takes away the sin of the world! John 1:29
For Christ, our Passover lamb, has been sacrificed. 1 Corinthians 5:7
...The blood of Jesus, his Son, purifies us from all sin. 1 John 1:7
The bones of the sacrificial lamb are not to be broken: Exodus 12:46-47, Numbers 9:12, Psalm 34:20
But when they came to Jesus and found that he was already dead, they did not break his legs. John 19:33
The Third Cup, the Cup of Redemption
Behold we are about to share the third cup of wine, which reminds us of God's redemption indicated in the scripture: “I will redeem you with an outstretched arm and with mighty acts of judgment.†Exodus 6:6 Blessed are you, O Lord our God, King of the universe, who created the fruit of the vine.
Jesus took the cup saying, “This cup is the new covenant in my blood which is poured out for you.†Luke 22:20
The Cup of Fulfillment, Hope and Freedom
We now partake of the fourth and final cup of wine as it is said: Blessed are you, O Lord our God, who created the fruit of the vine.
This is the cup Jesus was referring to in Luke 22:17-18 that he would not drink of again until all was fulfilled.
Blessed are those who are invited to the wedding supper of the Lamb! Revelation 19:9
