In the spirit of YeHoshua Ha Mashiach!  - MOUNT MOREH-YAH : The mountain where YeHoVaH is Our Teacher

                         Did Yahshua changed the Sabbath Days?
 
If changing the Sabbath to Sunday were on Yahshua’s agenda, He would have certainly prepared the disciples for such a change and such alteration of one of the Ten Commandments would have taken a lot of explaining on the part of Yahshua, and it will mean going against His father’s commandments “do not add or remove from my words“.
 
The messiah believed that he was sent by the Father, he did not come to do His own will, but the will of His Father. So Yahshua has No authority to change what the Father has established. He was sent by the Creator Yahweh
 
YAHSHUA’s Custom
You can tell what a person is like or believes by there actions. If we want to understand Yahshua’ teaching on the Sabbath question, we need to examine His actions. Yahshua’s earliest sermons confirm that He kept the entire Sabbath days. Notice what Yahshu’s CUSTOM was as stated in Luke (4:14-16). AND AS HIS CUSTOM WAS, He went into the synagogue on the Sabbath Day, and stood up to read. As His Custom Was…” All his life He kept the Sabbath day on the seventh day of the week (our Saturday). He never once kept the weekly Sabbath on Sunday—not once! It was on the Sabbath day that He said Isaiah’s prophecy was fulfilled as He began His public ministry. Luke 4:17-19: 17 and there was delivered unto him the book of the prophet Esaias. And when he had opened the book, he found the place where it was written, 18 The Spirit of the Yahweh is upon me, because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the broken hearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised, 19 To preach the acceptable year of the Yahweh. KJV
 
But the Bible is totally silent on this matter. Why? It may surprise you to know that this change simply never took place. Had Christ made the announcement that the Sabbath was to be kept on Sunday, the Jewish community would have viciously attacked him, even stoned him. Also, we would have an ample number of scriptures to turn to that would show us this change took place under Christ’s direction. Matthew, Mark, Luke, and John would have recorded the disciples’ reactions to this alteration to the law of Yahweh. The silence of the scriptures on this matter is overwhelming—there is no evidence, anywhere that Christ changed the Sabbath day to Sunday.
 
The New Testament Church, both Jewish and Gentile congregations, were observing the seventh day Sabbath, based upon the writings of Matthew, Mark, Luke, and John that Yahsua our Messiah was a Sabbath keeper. Many believe that He changed the Sabbath commandment because he healed people on the Sabbath day. Others believe Christ changed the Sabbath from Saturday to Sunday. There is also the belief that Christ wilfully broke the fourth commandment to let the Jews know that the Sabbath command was now abolished. What did Jesus believe about the seventh-day Sabbath
 
Did Yahshua Ever Abolish The 4th Commandment?
Many sincere churchgoers believe Christ’s crucifixion symbolically nailed the Sabbath command to the cross, thus abolishing the need to observe the Sabbath day. But the Bible speaks to the contrary: Yahshua Himself clearly stated that He did not come to abolish any of the Ten Commandments, including Sabbath observance. Christ actually came to Magnify or enlarge the spiritual understanding of the commandments of Yahweh. Yahshua own words were, “Do not think that I come to destroy the Law or the Prophets. I did not come to destroy but to fulfil. For assuredly I say to you till heaven and earth pass away, one jot or one tittle will by no means pass from the law…”—Matthew 5:17-18.
 
The Greek word translated fulfil (pleroo) means to fill to the full, such as filling up a glass to the very top with water. It means to make totally complete. Christ came to show the full meaning of the law so we would not only live by the letter of the law, but also strive to live by the spirit of the law.
 
There are those who seek to twist this scripture by saying that since Christ came, there is no longer a need to live by the law of God because Jesus fulfilled the law for us. But this cannot be the explanation of this passage because the rest of the chapter (Matthew 5) gives us example after example of how we are to live by the spirit of the law. For example, Christ taught that a man must not only refrain from committing physical adultery, he must also control his mind so as not to look upon a woman with lust in his heart (verse 27-28). Christ came to magnify the law and make it honorable (Isaiah 42:21), not to minimize it or cast it aside.
 
 Christ knew humans need moral principles to live by if they are to have a decent society. In making the law honorable, he affirmed its major importance. Yahshua gave us the true intent of God’s Holy Law – to govern the way we both think and act.
 
Jewish Legalism Does Not Nullify The Sabbath
It is true that religious Jews often attacked Yahshua concerning the Sabbath. But their contention was not over when Christ kept the Sabbath, but how Christ kept the Sabbath. The Pharisees and Sadducees were extremely strict in their observance of the seventh day of the week--so much so, that they made observing the Sabbath day a burden by adding all sorts of man made rules and regulations.
 
Yahweh had intended the Sabbath day to be a day of rest. It was actually a feast day (see Leviticus 23:2-3), a time when families were to physically stop from the toils of earning a living and keeping the home, and instead focus on worshiping  Yahweh, it was to be an enjoyable day of fellowship and study. Yahweh did not intend that observance of the Sabbath be so difficult the observer would have to fearfully focus more on minute details of how to keep it, rather than enjoy the refreshment that comes from keeping it within the clear guidelines God gave them.
 
You can see from the following example in Luke 6:6-10 that the Jews attacked  Yahshua over how he kept the Sabbath, not over what DAY the Sabbath was to be kept or whether it should be kept at all:
 
On another sabbath he entered the synagogue and taught, and there was a man there whose right hand was withered. The scribes and the Pharisees watched him to see whether he would cure on the sabbath, so that they might find an accusation against him. Even though he knew what they were thinking, he said to the man who had the withered hand, “Come and stand here.” He got up and stood there. Then Yahshua said to them, “I ask you, is it lawful to do good or to do harm on the sabbath, to save life or to destroy it ?" After looking around at all of them, he said to him, “Stretch out your hand.” He did so, and his hand was restored. But they were filled with fury and discussed with one another what they might do to Yahshua” NRSV.
 
Yahshua healing on the Sabbath was a sign of who he was and foreshadowed the miraculous healings to come when he returns to this earth to establish the Kingdom of God.
 
Isaiah prophesied of this time yet in the future: "Then the eyes of the blind shall be opened, and the ears of the deaf shall be unstopped. Then the lame shall leap like a deer, and the tongue of the dumb sing" (Isaiah 35:5, 6).
 
The Sabbath had become a heavy burden because the pedantic Scribes and Pharisees had turned Sabbath observance into a long and impossible list of do’s and don’ts--something God never intended. Yahshua Christ condemned human laws and traditions that distorted true worship of His Father (Mark 7:7-8). Yet Yahshua never stopped observing the Sabbath, and even the Apostles, including Paul, continued to keep the seventh-day Sabbath all their lives. The Bible states Paul taught Jews and Gentiles about the hope of the Kingdom of God on the Sabbath, never once commenting to them that the Sabbath was, by the way, now changed to Sunday (Acts 13:42-44; 17:1-4).
 
Keeping The Sabbath Is A Moral Issue
Many professing Christians fall for the poisonous argument that the Sabbath command was merely a ritualistic law that ended at the cross; but this line of thinking is blatantly wrong. First of all, Christ never said that when He died, the Sabbath Command would end; or that Sabbath observance would change to Sunday.
 
Secondly, breaking the Sabbath involves far more than breaking a minor rule. The Sabbath Command is spiritual in its intent and purpose--it was not just a ceremonial law that could be cast aside on a whim. And because Christ was Lord of the Sabbath (See Mark 2:28), He alone could nullify it or change it. Rather than changing it, however, as stated earlier, he fulfilled and confirmed it by setting the example of keeping the Sabbath for us.
 
Most would never think of missing an important anniversary date, ignoring a loved father on Father’s Day, or missing an important social function. But many people ignore God when He tells them to keep His Sabbath Holy. God considers violating the Sabbath command a blatant act of rebellion. Read Isaiah 58:13-14. How does God tell us to honour Him? This passage makes it plain:
 
If you refrain from trampling the Sabbath, from pursuing your own interests on my holy day; if you call the Sabbath a delight and the holy day of the LORD HONOURABLE; if you HONOUR it, not going your own ways, serving your own interests, or pursuing your own affairs; then you shall take delight in the LORD, and I will make you ride upon the heights of the earth; I will feed you with the heritage of your ancestor Jacob, for the mouth of the LORD has spoken.”
 
Morally, the Sabbath, along with all of the commandments, teaches humans how to live decent, orderly lives. Just setting aside one day to worship God prevents greed from over-sweeping individuals. It also keeps observant individuals mindful of the reality of God and their relationship to him. It promotes humility in the human mind when one takes time every Sabbath to focus on God’s greatness and that He is the creator. Worshiping Him when He tells us to, not when we choose to, goes a long way to remove pride from the human heart. Obedience is required in the keeping of the Sabbath; and as is obvious, there are few who truly are obedient to God today. Whether to honour or not to honour the Creator of the whole universe is indeed a serious moral decision.
 
If you have been told that the Sabbath is not part of the “Moral law”, think again! Morality concerns itself with behaviour. Obedience and honour toward your Creator are moral actions, and there is none more deserving of honour than God. We learn to honour God on the seventh day of every week by ceasing from our physical labours and spending time studying His word, going to Church, and fellowshipping with those whom God has called (Hebrews 10:25). Ignoring the Sabbath command is tantamount to saying to God, “I choose neither to respect nor revere You!” Christ set the example for us by carefully observing the Sabbath.
 
God’s Chosen Sign
Most do not realizer the Sabbath is a sign that Identifies God and those who belong to Him. The identifying sign of God’s people was the keeping of the Holy Sabbath, from sunset Friday to sunset Saturday (Leviticus 23:32). In the Bible, evening began when the sun went down (Nehemiah 13:19; Mark 1:32). It should be noted that only God could make a day holy. To decide to keep any other day “holy” is an act of either ignorance or flagrant presumption. The Sabbath command is found in several places in the Bible, including these important covenantal scriptures in Exodus 31:13, 17:
 
Speak to the children of Israel, saying: surely My Sabbaths you shall keep, for it is a sign between Me and you throughout your generations, that you may know that I am the LORD who sanctifies you. You shall keep the Sabbath, therefore it is holy to you.” Verse 17 continues by stating…”It [the Sabbath] is a sign between Me and the children of Israel FOREVER; for in six days the LORD made the heavens and the earth, and on the seventh day He rested and was refreshed.
 
Notice verse 17 of this special Sabbath covenant, "It is a sign between me and the children of Israel forever: for in six days the LORD made heaven and earth, and on the seventh day he rested, and was refreshed" (Ex. 31:17). It was on the seventh day of the creation week that He rested from the work of creation. God did not rest on Sunday, the first day of the week. Therefore, the Sabbath Day reminds us that God is our creator, and it is for this important reason that only the seventh day of the week can be thought of as consistently significant. Creation is the proof of God—the act of creating identifies Him as OUR Creator. The Sabbath is a sign from God that reminds His people, “I am the LORD, your Holy One, the creator….” (Isaiah 43:15)
 
Let’s not underestimate the importance of the Sabbath in the lives of Yahshua and His disciples—Christ taught His disciples to live by EVERY word of God (Matthew 4:4). Changing the Sabbath would have being evil and it will amount  to worshiping a different god and changing the scripture.
 
Sabbath Violation And National Captivity
Yahsua and His disciples understood the Sabbath commandant was essential for worshiping the TRUE God because it identified who the true God was and is. He and the disciples were well aware of Israel’s history. In Israel’s past the pagan nations surrounding Israel worshiped a wide and strange array of humanly devised gods; and they gave their gods names such as Baal, Chemosh, Ashtoreth and Molech.
 
In time the Israelites contaminated themselves with the worship of these false gods, violating God’s Holy Sabbath. Ignoring the Sabbath was no small offense to God. Israel’s breaking of His Holy Sabbath so angered God that He thrust Israel and Judah into national captivity. We read of God’s fury and the punishment of His people in Ezekiel 20:12-13, 18-20:
 
“Moreover I gave them my sabbaths, as a sign between me and them, so that they might know that I the LORD sanctify them. But the house of Israel rebelled against me in the wilderness; they did not observe my statutes but rejected my ordinances, by whose observance everyone shall live; and my sabbaths they greatly profaned.
 
I said to their children in the wilderness, Do not follow the statutes of your parents, nor observe their ordinances, nor defile yourselves with their idols. I YHWH am your God; follow my statutes, and be careful to observe my ordinances, and hallow my sabbaths that they may be a sign between me and you, so that you may know that I the Yahweh your God. But the children rebelled against me; they did not follow my statutes, and were not careful to observe my ordinances, by whose observance everyone shall live; they profaned my sabbaths”.
 
An important point to remember is that in Ezekiel 20, Yahweh calls them MY SABBATHS. They were not just the Sabbaths of the Jews. They were Yahweh’s Sabbaths.
 
The weekly (Saturday Sabbath) and annual Sabbaths (Holy Days of Leviticus 23) were created and made holy by Yahweh. 
 
During Christ’s ministry, Yashua ( Jesus) referred to himself as being “Lord of the Sabbath”—Mark 2:28. As the Lord or ruler of the Sabbath, Christ alone had the authority to regulate the Sabbath law and determine what day of the week the Sabbath was to fall on. Even to the day He died, Christ never relinquished his title as LORD of the Sabbath. He never cried out from the cross saying He was finished with the old Law and now would make the First Day Holy.
 
Conclusion
The Sabbath is a binding law that reminds for Yahweh’s people they are His people, and He is their God.
 
Nations surrounding ancient Israel worshiped their gods on various days utilising different pagan customs. That practice continues down to this day with most people receiving their religious practices from their familiars, not from the Bible.
 
The Bible, however, tells us Yahweh has only one specific weekly day of worship--the Sabbath day; and we are commanded to rest on that day.
 
The Sabbath is a sign from Yahweh that reminds His people He is their creator. Yahweh alone chose the seventh day to sanctify because he wanted us to finish every week by honouring and worshiping Him. In doing so, He knew we would never forget our special relationship to Him as the one from whom we receive the gift and blessings of life, both physical and spiritual.
 
Man never has nor ever will have the authority to make Sunday or any other day of the week holy. The seventh day of the week stands alone as being unique.
