All that is fine, but there is no need for a Passover under the new covenant. Jesus shed His blood once and for all time. Animal sacrifice is no longer necessary. Hence, Passover is no longer necessary.
Jesus instituted 2 ordinances: baptism and the Lord's supper. Only 2 necessary.
What are you talking about? Jesus does not abolish the law, He fulfills it.
Matthew 5:17 “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them.
Every one of us must appear before the Judgement to be judged for the things we have done.
1 Peter 4:17 For the time is come that judgment must begin at the house of God: and if it first begin at us, what shall the end be of them that obey not the gospel of God?
The blood of Jesus washes away every sin. So that cleans your robes. But we are not simply being judged for the things we haven't done but for those that we have done. The judgement begins with the house of God, but it doesn't stop there, it will go from Christians to Jews and ultimately to the unbelievers.
Matthew 25:21 His lord said unto him, Well done, thou good and faithful servant: thou hast been faithful over a few things, I will make thee ruler over many things: enter thou into the joy of thy lord.
The Lord was not commending the servant because his robes were spotless. He was commending him because he had been faithful over a few things. If your robes are not spotless you can't even begin to work. But no one appreciates a football player who at the end of the game has spotless robes. You start the game with spotless robes but it is a warfare, you are in the trenches. We appreciate them for what they have done, not because they started the game with a clean jersey.
Hebrews 9:13 For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh: 14 How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?
The process is the same, what has changed is the quality and effectiveness of the blood that is purifying our soul.
The Lord's table is the fulfillment of all those feasts. Most churches do not really keep the feast. According to
1 Corinthians 14:26 How is it then, brethren? when ye come together, every one of you hath a psalm, hath a doctrine, hath a tongue, hath a revelation, hath an interpretation. Let all things be done unto edifying.
The bread and wine are symbols that we are eating Christ, the reality is that we have received something from the living word in our daily walk that week and come to share it with others. That is what the feasts were. You offered up something, they cooked it and it was given to everyone. It was a giant pot luck barbecue. This is what it means to worship the Lord in Spirit and in Truth. In Spirit and in Truth you are in communion with the Lord Jesus and by sharing what you received others are fed as well. I have met with churches that practiced this, but few do.
Baptism is like Noah going through the flood or like the Children of Israel going through the Red Sea. Either this is a reality or it is simply empty religious practice. During the week are you going through the storm? Are Satan's armies bearing down on you about to destroy you only for God to step in and miraculously deliver you? If so, share those experiences at the Lord's table. If not being dunked in water is not benefiting you not being mixed with faith.
Hebrews 4:2 For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard it.
Most believers will go through the seven year tribulation because the Lord is going to make this word real to you. Baptism was a promise that you would have to go through the waters of death. Many christians think they can be country club Christians. There will be no country club Christians during the seven year tribulation. There will be no humpty dumpty Christians during the seven year tribulation.
But the same is true of Jews. Many think that being a Jew is based on DNA and not on faith. That is the mixed multitude that came out of Egypt. All of those ones will be power washed away by the end of the seven year tribulation and only those who have mixed the word with faith will be saved.
