14 I give God thanks, that I baptized none of you but Crispus and Caius:
15 Lest any should say that you were baptized in my name. (or any of my DEACONS names, either!!)
16 And I baptized also the household of Stephanus. Besides, I know not whether I baptized any other.
17 For Christ sent me not to baptize, but to preach the gospel: not in wisdom of speech, lest the cross of Christ should be made void.
See, St. Paul did not always busy himself with "other stuff".
That is what his helpers who were Deacons were there for.
It's amazing that the very One who was called "The Lamb of God*" should take the very MEAL the Moses had started (to make them remember what had saved them from the DEATH ANGEL*) to point the fact the HE was, indeed, that 'lamb'.
*John 1: 29. The next day John saw Jesus coming toward him and said, "Look, the Lamb of God, who takes away the sin of the world!
*Exodus 12:26-27
26. And when your children ask you, `What does this ceremony mean to you?'
27. then tell them, `It is the Passover sacrifice to the LORD, who passed over the houses of the Israelites in Egypt and spared our homes when he struck down the Egyptians.'"
The 'blood of the lamb' on the doorposts was a precursor of "The Blood of The LAMB" that is our Savior.
NIV Romans 5:9
9. Since we have now been justified by his blood, how much more shall we be saved from God's wrath through him!
NIV Acts 20:28
28. Keep watch over yourselves and all the flock of which the Holy Spirit has made you overseers. Be shepherds of the church of God, which he bought with his own blood.
NIV Romans 3:25-26
25. God presented him as a sacrifice of atonement, through faith in his blood. He did this to demonstrate his justice, because in his forbearance he had left the sins committed beforehand unpunished--
26. he did it to demonstrate his justice at the present time, so as to be just and the one who justifies those who have faith in Jesus.
NIV Romans 5:9
9. Since we have now been justified by his blood, how much more shall we be saved from God's wrath through him!
NIV 1 Corinthians 11:29
29. For anyone who eats and drinks without recognizing the body of the Lord eats and drinks judgment on himself.
Just what IS - "the body of the Lord"?
Moses did not start a "meal" but a system of bloody sacrifices of lambs which were then consummed at a ritualistic supper. You seem to be confusing modern Seder services with the ancient Passover when there was still a Temple.
The 'blood of the lamb' on the doorposts was a precursor of "The Blood of The LAMB" that is our Savior.
Are you really so naive as to think we Catholics do not know this?
The Lamb given by God to Abraham and Isaac is also a precursor of Christ, as was the sacrifice of Abel.
However Christ did not sacrifice lambs for our salvation, but rather He gave Himself, under species of bread and wine, just as did the Lord God's High Priest Melchisedech.
Genesis 14.18 But Melchisedech, the king of Salem, bringing forth bread and wine, for he was the priest of the most high God
St. Luke 22.19 And taking bread, he gave thanks and brake and gave to them, saying: This is my body, which is given for you. Do this for a commemoration of me.
20 In like manner, the chalice also, after he had supped, saying: This is the chalice, the new testament in my blood, which is being shed for you.
Hebrews 5.6 As he saith also in another place: Thou art a priest for ever, according to the order of Melchisedech.
Hebrews 12.24 And to Jesus the mediator of the new testament, and to the sprinkling of blood which speaketh better than that of Abel.
Do you see it yet? Or are you still not looking?
Christ is taking bread and wine like Melchisedech, consecrating them saying "This is my body which is given up for you" and "This is the chalice, the new testament in my blood, which is being shed for you." Then he is effecting a New Testment in His Precious Blood in the Eucharist and sprinkling His Precious Blood upon His people by having them consume the contents of the chalice. And notice this sacrifice, where he is giving His body and shedding His Precous Blood is taking place in a clean and unbloody manner.
Malachi 1.11 For from the rising of the sun even to the going down, my name is great among the Gentiles, and in every place there is sacrifice, and there is offered to my name a clean oblation: for my name is great among the Gentiles, saith the Lord of hosts.
When you see it, reread the book of Hebrews Chapter 5 through Chapter 12.
NIV 1 Corinthians 11:29
29. For anyone who eats and drinks without recognizing the body of the Lord eats and drinks judgment on himself.
Just what IS - "the body of the Lord"?
The Body of the Lord is the bread of the Eucharist consecrated into the Body of Christ.
St. Matthew 26.26 Take this all of you and eat it, this is my body.
Our common communion of the Body of Lord in the Eucharist causes our mystical communion in the Church as the Body of Christ which was effected by our Baptism.
1 Corinthians 10.16 The chalice of benediction which we bless, is it not the communion of the blood of Christ? And the bread which we break, is it not the partaking of the body of the Lord?
17 For we, being many, are one bread, one body: all that partake of one bread.
1 Corinthians 12.13 For in one Spirit were we all baptized into one body, whether Jews or Gentiles, whether bond or free: and in one Spirit we have all been made to drink.
We are not one because we all share one Bible, or we all believe in Christ (that is not enough!), or we all love each other. We are one body in Christ because of the Sacraments. We were "all baptized into one body" and "being many, are one bread, one body: all that partake of one bread".
