WHY keep the Sabbath day? Because is one the 10 Commandments from GOD that was never abolish by Christ or the disciples
What is the object of the Sabbath? A celebration of the creation of the world and a time to connect with God
Who made it? When was it made, and for whom? It was made for our creator after he ended all his work
Which day is the true Sabbath? The true Sabbath is the seven day Friday sundown to Saturday sundown
By what Bible authority people celebrate the Sabbath on the First day? None Jesus, his disciples & the old church celebrated the Sabbath on the seventh day not the first.
What Scripture the christian church uses to justify their Sunday worship and the abolishment of the Sabbath? Christian now days are using scripture that make reference to the "Mosaic Law" also call "The Law of Moses" and twisting the words of Paul to say that the Sabbath shall not be honor any longer when Jesus, The disciples and Paul all kept them. Worshiping God on Sunday or any other day of the week is not wrong, Keeping the Sabbath day Holy is a commandments that was never abolish by anyone in the faith and just like we supposed to keep all 10 Commandments we also shall keep the Sabbath . Read Study Commandments for more information.
Are the gentiles supposed to honor the Sabbath? Yes. People uses as an excuse not celebrate the Sabbath the following verse Acts 15:20 but that we write to them to abstain from things polluted by idols, from sexual immorality,[d] from things strangled, and from blood. But they fail to discuss Acts 15:11 But we believe that through the grace of the Lord Jesus Christ[a] we shall be saved in the same manner as they.” In other words we are equal to any Jew, that thru the grace of our savior we are all now save, In addition they fail to mention Acts 15:21 For Moses has had throughout many generations those who preach him in every city, being read in the synagogues every Sabbath.” Meaning the gentiles were already aware of the Commandments of God because they (The Commandments) were preach when Every Sabbath meaning my friends the gentiles were following the commandments of God including the Sabbath since they were all meeting on that day.
Here are the facts about both days, as plainly stated in the Word of God:
60 Bible Facts on the about Seventh day of the Week (Friday Sundown to Saturday Sundown)
1. After working the first six days of the week in creating this earth, God rested on the seventh day. Genesis 2:1-3.
2. This stamped that day as God's rest day, or Sabbath day, as Sabbath day means rest day. To illustrate: When a person is born on a certain day, that day thus becomes his birthday. So when God rested upon the seventh day, that day became His rest, or Sabbath, day.
3. Therefore the seventh day must always be God's Sabbath day. Can you change your birthday from the day on which you were born to one on which you were not born? No. Neither can you change God's rest day to a day on which He did not rest. Hence the seventh day is still God's Sabbath day.
4. The Creator blessed the seventh day. Genesis 2:3.
5. He sanctified the seventh day. Exodus 20:11.
6. He made it the Sabbath day in the Garden of Eden. Genesis 2:1-3.
7. It was made before the fall; hence it is not a type; for types were not introduced till after the fall.
8. Jesus says it was made for man, that is, for the race, as the word man is here unlimited; hence, for the Gentile as well as for the Jew. Mark 2:27.
9. Not only is the Sabbath made for man, but Jesus said that He was Lord of the Sabbath. Mark 2:28.
10. It is a memorial of creation. Exodus 20:11; 31:17. Every time we rest upon the seventh day, as God did at creation, we commemorate that grand event.
11. It was given to Adam, the head of the human race. Mark 2:27; Genesis 2:1-3.
12. It is not a Jewish institution, for it was made 2,300 years before ever there was a Jew.
13. The Bible never calls it the Jewish Sabbath, but always "the Sabbath of the Lord thy God." Men should be cautious how they stigmatize God's holy rest day.
14. Evident reference is made to the Sabbath and the seven-day week all through the patriarchal age. Genesis 2:1-3; 8:10,12; 29:27,28, etc.
15. It was a part of God's law before Sinai. Exodus 16:4,23-29.
16. Then God placed it in the heart of His moral law. Exodus 20:1-17. Why did He place it there if it was not like the other nine precepts, which all admit to be immutable?
17. The seventh-day Sabbath was commanded by the voice of the living God. Deuteronomy 4:12,13.
18. Then He wrote the commandment with His own finger. Exodus 31:18.
19. He engraved it in the enduring stone, indicating its imperishable nature. Deuteronomy 5:22.
20. It was sacredly preserved in the ark in the holy of holies. Deuteronomy 10:1-5.
21. God forbade work upon the Sabbath, even in the most hurrying times. Exodus 34:21.
22. God destroyed the Israelites in the wilderness because they profaned the Sabbath. Ezekiel 20:12,13.
23. It is the sign of the true God, by which we are to know Him from the false gods. Ezekiel 20:20.
24. God promised that Jerusalem should stand forever if the Jews would keep the Sabbath. Jeremiah 17:24,25.
25. He sent them into the Babylonish captivity for breaking it. Nehemiah 13:15-22.
15 In those days I saw people in Judah treading winepresses on the Sabbath and bringing in grain and loading it on donkeys, together with wine, grapes, figs and all other kinds of loads. And they were bringing all this into Jerusalem on the Sabbath. Therefore I warned them against selling food on that day. 16 People from Tyre who lived in Jerusalem were bringing in fish and all kinds of merchandise and selling them in Jerusalem on the Sabbath to the people of Judah. 17 I rebuked the nobles of Judah and said to them, “What is this wicked thing you are doing—desecrating the Sabbath day? 18 Didn’t your ancestors do the same things, so that our God brought all this calamity on us and on this city? Now you are stirring up more wrath against Israel by desecrating the Sabbath.”
19 When evening shadows fell on the gates of Jerusalem before the Sabbath, I ordered the doors to be shut and not opened until the Sabbath was over. I stationed some of my own men at the gates so that no load could be brought in on the Sabbath day. 20 Once or twice the merchants and sellers of all kinds of goods spent the night outside Jerusalem. 21 But I warned them and said, “Why do you spend the night by the wall? If you do this again, I will arrest you.” From that time on they no longer came on the Sabbath. 22 Then I commanded the Levites to purify themselves and go and guard the gates in order to keep the Sabbath day holy.
26. He destroyed Jerusalem for its violation. Jeremiah 17:19 - 27.
This is what the Lord said to me: “Go and stand at the Gate of the People,[c] through which the kings of Judah go in and out; stand also at all the other gates of Jerusalem. 20 Say to them, ‘Hear the word of the Lord, you kings of Judah and all people of Judah and everyone living in Jerusalem who come through these gates. 21 This is what the Lord says: Be careful not to carry a load on the Sabbath day or bring it through the gates of Jerusalem. 22 Do not bring a load out of your houses or do any work on the Sabbath, but keep the Sabbath day holy, as I commanded your ancestors. 23 Yet they did not listen or pay attention; they were stiff-necked and would not listen or respond to discipline. 24 But if you are careful to obey me, declares the Lord, and bring no load through the gates of this city on the Sabbath, but keep the Sabbath day holy by not doing any work on it, 25 then kings who sit on David’s throne will come through the gates of this city with their officials. They and their officials will come riding in chariots and on horses, accompanied by the men of Judah and those living in Jerusalem, and this city will be inhabited forever. 26 People will come from the towns of Judah and the villages around Jerusalem, from the territory of Benjamin and the western foothills, from the hill country and the Negev, bringing burnt offerings and sacrifices, grain offerings and incense, and bringing thank offerings to the house of the Lord. 27 But if you do not obey me to keep the Sabbath day holy by not carrying any load as you come through the gates of Jerusalem on the Sabbath day, then I will kindle an unquenchable fire in the gates of Jerusalem that will consume her fortresses.’”
27. God has pronounced a special blessing on all the Gentiles who will keep it. Isaiah 56:6,7.

Your people will rebuild the ancient ruins
and will raise up the age-old foundations;
you will be called Repairer of Broken Walls,
Restorer of Streets with Dwellings.
13 “If you keep your feet from breaking the Sabbath
and from doing as you please on my holy day,
if you call the Sabbath a delight
and the Lord’s holy day honorable,
and if you honor it by not going your own way
and not doing as you please or speaking idle words,
14 then you will find your joy in the Lord,
and I will cause you to ride in triumph on the heights of the land
and to feast on the inheritance of your father Jacob.”
For the mouth of the Lord has spoken.
32. All the holy prophets kept the seventh day.
Moses Isaiah Jesus The Apostles Jeremiah Elijah & more
33. When the Son of God came, He kept the seventh day all His life. Luke 4:16; John 15:10. Thus He followed His Father's example at creation. Shall we not be safe in following the example of both the Father and the Son?
34. The seventh day is the Lord's day. See Revelation 1:10; Mark 2:28; Isaiah 58:13; Exodus 20:10.
35. Jesus was Lord of the Sabbath (Mark 2:28), that is, to love and protect it, as the husband is the lord of the wife, to love and cherish her. 1 Peter 3:6.
36. He vindicated the Sabbath as a merciful institution designed for man's good. Mark 2:23-28.

40. The pious women who had been with Jesus carefully kept the seventh day after His death. Luke 23:56.
41. Thirty years after Christ's resurrection, the Holy Spirit expressly calls it "the sabbath day." Acts 13:14.
42. Paul, the apostle to the Gentiles, called it the "sabbath day" in A.D. 45. Acts 13:27. Did not Paul know? Or shall we believe modern teachers, who affirm that it ceased to be the Sabbath at the resurrection of Christ?
43. Luke, the inspired Christian historian, writing as late as A.D. 62, calls it the "sabbath day." Acts 13:44.
44. The Gentile converts called it the Sabbath. Acts 13:42.
45. In the great Christian council, A.D. 49, in the presence of the apostles and thousands of disciples, James calls it the "sabbath day." Acts 15:21.
46. It was customary to hold prayer meetings upon that day. Acts 16:13.
47. Paul read the Scriptures in public meetings on that day. Acts 17:2,3.
48. It was his custom to preach upon that day. Acts 17:2,3.
49. The Book of Acts alone gives a record of his holding eighty-four meetings upon that day. See Acts 13:14,44; 16:13; 17:2; 18:4,11.
50. There was never any dispute between the Christians and the Jews about the Sabbath day. This is proof that the Christians still observed the same day that the Jews did.
51. In all their accusations against Paul, they never charged him with disregarding the Sabbath day. Why did they not, if he did not keep it?
52. But Paul himself expressly declared that he had kept the law. "Neither against the law of the Jews, neither against the temple, nor yet against Caesar, have I offended anything at all." Acts 25:8. How could this be true if he had not kept the Sabbath?
53. The Sabbath is mentioned in the New Testament fifty-nine times, and always with respect, bearing the same title it had in the Old Testament, "the sabbath day."
54. Not a word is said anywhere in the New Testament about the Sabbath's being abolished, done away, changed, or anything of the kind.
55. God has never given permission to any man to work upon it. Reader, by what authority do you use the seventh day for common labor?
56. No Christian of the New Testament, either before or after the resurrection, ever did ordinary work upon the seventh day. Find one case of the kind, and we will yield the question. Why should modern Christians do differently from Bible Christians?
57. There is no record that God has ever removed His blessing or sanctification from the seventh day?
58. As the Sabbath was kept in Eden before the fall, so it will be observed eternally in the new earth after the restitution. Isaiah 66:22,23.
59. The seventh-day Sabbath was an important part of the law of God, as it came from His own mouth, and was written by His own finger upon stone at Sinai. See Exodus 20. When Jesus began His work, He expressly declared that He had not come to destroy the law. "Think not that I am come to destroy the law, or the prophets." Matthew 5:17.
60. Jesus severely condemned the Pharisees as hypocrites for pretending to love God, while at the same time they made void one of the Ten Commandments by their tradition. The keeping of Sunday is only a tradition of men.
King of Kings Lord of Lords
The Apostles and the Old Church following the Sabbath:
Acts 17:1 (NKJV) Now when they had passed through Amphipolis and Apollonia, they came to Thessalonica, where there was a synagogue of the Jews. Acts 17:2 Then Paul, as his custom was, went in to them, and for three Sabbaths reasoned with them from the Scriptures, Acts 17:3 explaining and demonstrating that the Messiah had to suffer and rise again from the dead, and [saying], "This Yahushua whom I preach to you is the Messiah." Acts 17:4 And some of them were persuaded; and a great multitude of the devout Greeks, and not a few of the leading women, joined Paul and Silas.
Here we see that Paul went to a Sabbath service where there were both Jews and Greeks. The scripture also mentions that this was a regular custom of Paul. Was this also the custom of Yahushua the Messiah?
Luke 4:16 (NKJV) So He came to Nazareth, where He had been brought up. And as His custom was, He went into the synagogue on the Sabbath day, and stood up to read.
So here we can see that 22 years after Yahushua's death and resurrection the disciples were attending Sabbath services. In no place do we see Paul or any other disciple teaching them that they should come back the next day for a 'first day of the week' service. But they went to three Sabbath services where there were both Jews and Greeks present. So then the doctrine that says the Jews have their day (the 7th day) and the Gentiles have their day (the 1st day) is foreign to scripture.
Some would argue that Paul was at the synagogue only because that is where he would find people to witness to...not to observe the Sabbath. But the scripture does not say that. This is an assumption that those who refuse the simplicity of the scriptures want to make, not one that the scriptures support. Again, the Seventh Day is called "The Sabbath day" in this passage.
So lets see where we are at now..
Acts 13:13 (NKJV) Now when Paul and his party set sail from Paphos, they came to Perga in Pamphylia; and John, departing from them, returned to Jerusalem. Acts 13:14 But when they departed from Perga, they came to Antioch in Pisidia, and went into the synagogue on the Sabbath day and sat down. Acts 13:15 And after the reading of the Law and the Prophets, the rulers of the synagogue sent to them, saying, "Men [and] brethren, if you have any word of exhortation for the people, say on."
So here is another example where Paul and the other disciples came to the Synagogue in Perga to attend the Sabbath Service.
A little later in the chapter, after Paul shares Yahushua with them we see that the Gentiles were quite interested.
Acts 13:42 (NKJV) So when the Jews went out of the synagogue, the Gentiles begged that these words might be preached to them the next Sabbath.
Now here is a perfect situation for Paul to tell these Gentiles "Hey just come back tomorrow, we keep the Sabbath on the first day now!" But we don't see this written anywhere in scripture.
Acts 13:43 Now when the congregation had broken up, many of the Jews and devout proselytes followed Paul and Barnabas, who, speaking to them, persuaded them to continue in the grace of Yahweh Acts 13:44 On the next Sabbath almost the whole city came together to hear the word of Yahweh.
So here is the fifth time that the disciples attended a Sabbath service on the day that Yahweh sanctified at creation. Again, the seventh day is called "the Sabbath" in this passage.
Acts 15:21 For Moses has had throughout many generations those who preach him in every city, being read in the synagogues every Sabbath.”
Acts 16:11 (NKJV) Therefore, sailing from Troas, we ran a straight course to Samothrace, and the next [day] came to Neapolis, Acts 16:12 and from there to Philippi, which is the foremost city of that part of Macedonia, a colony. And we were staying in that city for some days. Acts 16:13 And on the Sabbath day we went out of the city to the riverside, where prayer was customarily made; and we sat down and spoke to the women who met [there].
It was the custom of the Jews of that day for the rabbi to shut down the synagogue if there were not at least 10 men that would show up for the Sabbath meeting. This could very well be why there were women meeting by the riverside for prayer. Nevertheless, we see that the disciples sought a place to meet for the Sabbath and they did. Again, the seventh day is called "the Sabbath Day" in this passage.
Acts 18:1 (NKJV) After these things Paul departed from Athens and went to Corinth. Acts 18:2 And he found a certain Jew named Aquila, born in Pontus, who had recently come from Italy with his wife Priscilla (because Claudius had commanded all the Jews to depart from Rome); and he came to them. Acts 18:3 So, because he was of the same trade, he stayed with them and worked; for by occupation they were tentmakers. Acts 18:4 And he reasoned in the synagogue every Sabbath, and persuaded both Jews and Greeks.
So we see that he worked on the other days as a tent maker...but on the Sabbath He was not. And here again we see that both Jews and Greeks are in the synagogue and on the Sabbath. Paul also is among them attending the Sabbath services. The interesting thing about this verse is that instead of the scripture saying that they attended only one or three Sabbath services, it says that he was there every Sabbath persuading both Jews and Greeks. Again, the seventh day is called "the Sabbath" in this passage so we know that we can at least count one. Let's do that..
Now if Paul was in Corinth and was reasoning in the synagogue every Sabbath, if we could find out how long he stayed in Corinth then we would know how many Sabbaths he actually attended. Let's look further
Acts 18:5 (NKJV) When Silas and Timothy had come from Macedonia, Paul was compelled by the Spirit, and testified to the Jews [that] Yahushua [is] the Messiah. 6 But when they opposed him and blasphemed, he shook [his] garments and said to them, "Your blood [be] upon your [own] heads; I [am] clean. From now on I will go to the Gentiles." 7 And he departed from there and entered the house of a certain [man] named Justus, [one] who worshiped God, whose house was next door to the synagogue. 8 Then Crispus, the ruler of the synagogue, believed on the Master with all his household. And many of the Corinthians, hearing, believed and were baptized. 9 Now the Master spoke to Paul in the night by a vision, "Do not be afraid, but speak, and do not keep silent; 10 "for I am with you, and no one will attack you to hurt you; for I have many people in this city." 11 And he continued [there] a year and six months, teaching the word of God among them.
A year and six months! Finally the ruler of the synagogue was converted to Yahushua and Paul was there a year and six months! So the scripture says that Paul was there every Sabbath and that he was there for a year and six months. If we counted this by our present calendar that would give us 52 Sabbaths in a year plus 26 Sabbaths in the following six months which gives us a total of 78 Sabbaths! Now lets add this to our present total:
So we can see that the disciples observed the Sabbath and attended a Sabbath service 85 times in the book of acts alone! Again, the seventh day is called "the Sabbath" in this passage.
Now how many times do we see them meeting together on the first day? Some would cite one example in Acts 20. Let's examine the text...
Acts 20:6 (NKJV) But we sailed away from Philippi after the Days of Unleavened Bread, and in five days joined them at Troas, where we stayed seven days. Acts 20:7 Now on the first [day] of the week, when the disciples came together to break bread, Paul, ready to depart the next day, spoke to them and continued his message until midnight.
Here we see an example of the disciples gathering together on the first day of the week. There is no mention of a Sabbath being observed in this verse. Nowhere is this day called "The Sabbath". In fact, we know that Paul was ready to depart the next day. According to verse 7, Paul spoke to them a message because for this very reason.
Now some would say that coming together to 'break bread' constitutes a meeting that includes the observance of partaking in Yahushua's body. But this is not true...consider this verse:
Acts 2:44 (NKJV) Now all who believed were together, and had all things in common, 45 and sold their possessions and goods, and divided them among all, as anyone had need. 46 So continuing daily with one accord in the temple, and breaking bread from house to house, they ate their food with gladness and simplicity of heart, 47 praising Yahweh and having favor with all the people. And Yahweh added to the assembly daily those who were being saved.
According to this scripture, breaking bread was not an uncommon thing to do on a daily basis. It was one of the customs in those days to eat their 'daily bread'. Even in Yahushua's prayer He said "Give us this day our daily bread".
So we cannot confirm that this scripture in Acts 20 is a Sabbath day observance. In fact, nowhere does it say that the first day of the week is the Sabbath. But the 7th day of the week is always called "the Sabbath" in the 'new testament.' Unless you don't believe in the New Testament, you would have to conclude that this was not a Sabbath meeting. So what was it really? Many may not realize that in scripture, a new day begins at sundown. This would mean that at sundown on 'Saturday', the first day of the week begins. This was most probably an 'after Sabbath' fellowship meal where Paul continued to speak until midnight because he wanted to get as much teaching in as possible before he departed the next day.
Nevertheless some will hang onto this one verse so that they don't have to forsake tradition and keep the true Sabbath. But you can search the scriptures from Genesis to Revelations and you will not find a single verse that says His Sabbath was changed to a different day. There is not a single verse that tells us that the Ten Commandments are not to be kept. And there is not a single verse that prophesied either of these two events occurring! In fact, the scriptures declare the seventh day to be the Sabbath in the Law, in the words of the prophets, in the writings about Yahushua and in the acts of the apostles as well as in the scriptures that speak of Yahweh's kingdom.
43 Bible Facts about The First Day of the Week

On March 7 321 " On the venerable Day of the Sun let the magistrates and people residing in cities rest, and let all workshops be closed. In the country, however, persons engaged in agriculture may freely and lawfully continue their pursuits; because it often happens that another day is not so suitable for grain-sowing or vine-planting; lest by neglecting the proper moment for such operations the bounty of heaven should be lost." . This law passed by Constantine does not even sound like the Sabbath that our creator establish which forbids any kind of work at all on his Holy day.
42. Despite the official adoption of Sunday as a day of rest by Constantine, the two days (The Sabbath & Sunday) continued to be used side-by-side until at least the Calendar of 354 and probably later.
43. In 363, Canon 29 of the Council of Laodicea prohibited observance of the Jewish Sabbath (Saturday), and encouraged Christians to work on the Saturday and rest on the Lord's Day (Sunday). The fact that the canon had to be issued at all is an indication that adoption of Constantine's decree of 321 was still not universal, not even among Christians. It also indicates that Jews were observing the Sabbath on the Saturday.
44. There is also evidence that the early disciples kept the Sabbath on the true day:
"The primitive Christians did keep the Sabbath of the Jews;.therefore the Christians for a long time together, did keep their conventions on the Sabbath, in which some portion of the Law were read: and this continued till the time of the Laodicean council." The Whole Works of Jeremey Taylor, Vol. IX, p416 (R. Heber's Edition, Vol.XII, p.416)
"The ancient Christians were very careful in the observation of Saturday, or the seventh day..It is plain that all the Oriental churches, and the greatest part of the world, observed the Sabbath as a festival...Athanasius likewise tells us that they held religious assemblies on the Sabbath, not because they were infected with Judaism, but to worship [Yahushua], the [Master] of the Sabbath, Epiphanius says the same." Antiquities of the Christian Church, Vol. II, Book XX, chap. 3, Sec. 1, 66.1137, 1138
"Ambrose, the celebrated bishop of Milan, said that when he was in Milan he observed Saturday, but when in Rome observed Sunday. This gave rise to the proverb 'When you are in Rome, do as Rome does,' " Heylyn, The History of the Sabbath, 1613
Here are over hundred plain Bible facts upon this question, showing conclusively that the seventh day is the Sabbath of the Lord in both the Old and New Testament.You may now be asking yourself, is all of this important, does it really matter? Well, let me close with this verse. "Blessed are they that do his commandments that they may have right to the tree of life, and may enter in through the gates into the city." Rev. 22:14.
