Where do we find the passover becomes the mass?

Lutero:
Where do we find the passover becomes the mass?

Here.

Matthew 26:16-18

King James Version (KJV)
¹⁶ And from that time he sought opportunity to betray him.
¹⁷ Now the first day of the feast of unleavened bread the disciples came to Jesus, saying unto him, Where wilt thou that we prepare for thee to eat the passover?
¹⁸ And he said, Go into the city to such a man, and say unto him, The Master saith, My time is at hand; I will keep the passover at thy house with my disciples.

Note that Jesus prepares the disciples for a Passover. But this is what He says during that Passover:
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.
²⁷ And he took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it;
²⁸ For this is my blood of the new testament, which is shed for many for the remission of sins.

Jesus prepared the disciples for a Passover. But during that Passover, celebrated the Mass. St. Paul obviously understands this:
1 Corinthians 5:7

King James Version (KJV)
⁷ Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificed for us:

So what does it mean that YOU are now UNLEAVENED?.

St. Paul is using "leavening" in a metaphorical sense. To understand the metaphor, you must go to the Old Testament. Before the Passover, the Jews were supposed to clean house throw out all leavening:
Exodus 12:15

King James Version (KJV)
¹⁵ Seven days shall ye eat unleavened bread; even the first day ye shall put away leaven out of your houses: for whosoever eateth leavened bread from the first day until the seventh day, that soul shall be cut off from Israel.

When St. Paul says, Purge out therefore the old leaven, he is referring to sin. We become one bread, one body with Christ. And before we eat of the Eucharist, our Passover, we must examine ourselves:

1 Corinthians 11:28-30

King James Version (KJV)
²⁸ But let a man examine himself, and so let him eat of that bread, and drink of that cup.
²⁹ For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body.
³⁰ For this cause many are weak and sickly among you, and many sleep.

When we unite ourselves to Christ in the Holy Eucharist, we must be a pure lump, that ye may be a new lump, as ye are unleavened, without sin.

Where does scripture say if they did not eat the lamb they would die?

Hebrews 10:

King James Version (KJV)
²⁵ Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching.
²⁶ For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,
²⁷ But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.
²⁸He that despised Moses' law died without mercy under two or three witnesses:

I know there was something they had to do to preserve their lives.. but it was not to eat the lamb ... infact they were told to burn the lamb they did not eat.. so what was the sign they were to use to save their lives?

To mark the doorposts with the blood.

First you have to show where God commanded the "mass "as a new passover ...

On the contrary, you have to show where Scripture says that the Mass is not the Passover. I have shown you where our Traditions and doctrines are in line with Scripture. You have shown nothing from Scripture. Absolutely nothing.

What you do is isogesus..

What you offer is mere opinion with no support.

you look up scripture or read it to support what you want it to say . The passover was once a year as a memorial commandment ..it pointed to Christ

Exactly! It pointed to Christ. Because Christ is the True Passover. And long ago, it was prophecied that Christ would become the Daily Offering:

Malachi 1:11

King James Version (KJV)
¹¹ For from the rising of the sun even unto the going down of the same my name shall be great among the Gentiles; and in every place incense shall be offered unto my name, and a pure offering: for my name shall be great among the heathen, saith the Lord of hosts.

It is indeed a fearful thing to fall into the hands of the living God..because there was only ONE sacrifice for sin.. and that was on Calvary.. there are no more daily sacrifices

It is that same sacrifice of Calvary which we offer and consume. 

Maria.. what did the cross accomplish ? How is is sufficient to you?

Jesus accomplished the salvation of all who OBEY Him on the Cross. 

Hebrews 5:

King James Version (KJV)
⁸ Though he were a Son, yet learned he obedience by the things which he suffered;


⁹ And being made perfect, he became the author of eternal salvation unto all them that obey him;

In so doing, He established an example that we should follow in His steps:

1 Peter 2:21

King James Version (KJV)
²¹ For even hereunto were ye called: because Christ also suffered for us, leaving us an example, that ye should follow his steps:

Sincerely,

De Maria
