I use Yah or Yahuah for the Tetragrammaton as I believe that is the correct pronunciation of the Father's name. Yahusha for his Son. I don't have eSword on this computer with a copy of the Cepher that uses these names (Cepher.net) so I'm using the KJV from BLB.org online for verses which uses GOD & Jesus.
The questions are about the feast of Unleavened Bread.
...Are you Jew or Christian, and if Christian, do you think that Christians have a mandate to celebrate this event, or is it something that you choose to do?
There are several peoples mentioned in the Bible, but only Israel is called "Yah's People", the same people he would lead out of captivity in Egypt (Mizrayim) and into the promised land to fulfill his covenant with Abram to make many nations of Abram.
In Gen 35:10 we see Jacob, the son of Isaac, the son of Abraham "whom the promise is given" or "the covenant was cut with Yah" (Gen 12:1-3) receive this name after wrestling with Yahusha.
2Ki 13:23 is the first place the term "Jew" is mentioned and while we use that term loosely with the Nation State of Israel (1948+) and it's applied to all of "Israel, Yah's people" it is referencing the "Lower Kingdom" that was predominantly composed of the tribe of Judah, one of the 12 tribes of Yah's Israel. The "Northern Kingdom" was cast out into the nations and is usually referred to as Jacob / Israel / Ephraim (the larger tribe of Jacobs two son's Ephraim & Manasseh) or the "Lost Tribes" as their identity was lost when they were dispersed into the "nations" goyim.
So to ask if one is Jew or Christian is asking if one is "of the tribe of Judah or Christian", Judah is a part of Israel and thus Yah's children but is not the whole people and the Rothschilds and UN state created in 1948 is definitely not Yah's children. There may be a few true decedents in the state of Israel from Judah but the majority are usurpers from the Macabean period IMO.
But to answer the question... I consider myself a part of Yah's Israel (Abraham's seed Jacob/Israel) through faith Gal 3:6-9. I consider myself a Christian in the true sense of the word (one that follows the Christ / Messiah) but not how the term is used today in the world which do not follow the person they are named after.
The term "Christian" today means a Sunday sabbath (not Yah's 7th day Sabbath) keeper that follows the twisted teaching of Rome (Catholic church) and it's children (Protestant church) and all the various denominations of Sunday Worship.
Yahusha put it pretty plainly:
[Jhn 14:15 KJV] 15 If ye love me, keep my commandments.
[Exo 20:6 KJV] 6 And shewing mercy unto thousands of them that love me, and keep my commandments.
[Deu 5:10 KJV] 10 And shewing mercy unto thousands of them that love me and keep my commandments.
[Jhn 14:23 KJV] 23 Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him.
He also made it pretty plain to those who don't:
[Mat 7:21-23 KJV] 21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. 22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? 23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
Christian's DO NOT keep his commandments nor attempt to, but work lawlessness/iniquity (Torah-less-ness). Torah is the Law he is referring to, the Law of his Father whom he said he only does the will of and who is his second witness. There are many examples of where today's Christianity does not follow Christ’s own teachings which are all wrapped up in the Torah and the Prophets as he told the Rich Young Ruler in Mat 22:40.
...please tell me about the steps you go through. We don't celebrate it, but I'm curious if we should.
The Feasts
Yah's Feasts are found in Lev 23, you should read the whole thing. Food laws are in Lev 11, in both you will see that they are to be kept "forever" which seems impossible for 3 of them since it requires a Temple be standing to bring a sacrifice to and the last temple was destroyed in 70AD. Or was it?
Currently the state of Israel is about to open a new one with the sacrificing of a perfect Red Heifer required in the past to sanctify the temples, but the animal sacrifices were done away with the great sacrifice and propitiation of Yahusha on the cross.
When he said "it is finished" meaning the work Yah sent him to accomplish, the ability for the world to repent and be forgiven of their sins (there is no remission of sin without blood Heb 9:22) was accomplished with his PERFECT sacrifice ONCE AND FOR ALL.
Faith is what saves, it's in Yahusha's covering blood we are seen as righteous as Abram was accounted righteous, through faith.
[Gal 3:6-8 KJV] 6 Even as Abraham believed God, and it was accounted to him for righteousness. 7 Know ye therefore that they which are of faith, the same are the children of Abraham. 8 And the scripture, foreseeing that God would justify the heathen through faith, preached before the gospel unto Abraham, [saying], In thee shall all nations be blessed.
So what about the temple and sacrifices?
[1Co 6:19 KJV] 19 What? know ye not that your body is the temple of the Holy Ghost [which is] in you, which ye have of God, and ye are not your own?
[Heb 13:15 KJV] 15 By him therefore let us offer the sacrifice of praise to God continually, that is, the fruit of [our] lips giving thanks to his name.
I believe that the Word says we are to keep the Feasts of Yah forever and that with the Brit Hadasha (New Covenant) we are able to do it without a sacrifice (which was for sin, Yah wanted obedience not sacrifices) because our savior Yahusha made the final perfect sacrifice. This is also why all the talk of a 3rd temple (state of Israels current goal) and animal sacrifices starting up again in the Millennium is bunk.
[1Sa 15:22 NIV] 22 But Samuel replied: "Does the LORD delight in burnt offerings and sacrifices as much as in obeying the LORD? To obey is better than sacrifice, and to heed is better than the fat of rams.
...Do you remove the yeast from your home and sacrifice an animal?
Removing "leaven" and eating "unleavened bread" are what the feast of Unleavened Bread are all about IMO. Leaven represents sin in the Bible, there was only one "unleavened" sinless "bread" in th Bible and that was Yahusha.
[Jhn 6:51, 58 KJV] 51 I am the living bread which came down from heaven: if any man eat of this bread, he shall live for ever: and the bread that I will give is my flesh, which I will give for the life of the world. ... 58 This is that bread which came down from heaven: not as your fathers did eat manna, and are dead: he that eateth of this bread shall live for ever.
[1Co 11:27 KJV] 27 Wherefore whosoever shall eat this bread, and drink [this] cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord.
The tradition of removing all leaven from the house prior to the start of the 15th of Abib is one that the "Jews" go to ridiculous lengths to accomplish, google it up along with Sabbath elevators, it's ridiculous.
Like circumcision, it's not a physical requirement anymore but a matter of the heart. Yah wants a circumcised heart, not a piece of flesh.
[Rom 2:29 KJV] 29 But he [is] a Jew, which is one inwardly; and circumcision [is that] of the heart, in the spirit, [and] not in the letter; whose praise [is] not of men, but of God.
Likewise it's about removing sin from your life, not freaking out when you find some baking soda in your cupboard on day 2 of ULB. That being said, we do remove leaven (Yeast and leavened bread) from our house (we put it in the garage for a week) as an exercise in directing our thoughts towards the sin in our lives that we might not have noticed without taking that time to reflect deeper on where that sin might be.
The fact that almost every year we find some leaven still in the house is a reminder that we will never be without sin in this lifetime and only the covering blood of Yahusha can save us.
...Is painting the blood over the door still required?
No. It was only for the first Passover in Mizraim, not the memorial of that time which is what we are required to celebrate with the Passover Feast.
Thank you for your interest and I encourage you to not believe a word I have written and search it out for yourself. I spent a lot of years in a Sunday church just listening and not seeking truth, happy to get my weekly "indulgence" so I could go back to purposefully sinning the next 6 days, knowing all along I had said a prayer and had my "ticket punched" for heaven.
Spoiler Alert: Once saved, always saved as taught by the Sunday church is a total lie, read your Bible!
