Is it a sin to observe the Sabbath on Sunday

Is it a sin to observe the Sabbath on Sunday?

It is a sin to not observe the Sabbath on Saturday, because it is the real and correct day of rest that God has blessed and sanctified. (Genesis 2:2-3)

It will become a sin to observe the Sabbath on Sunday when the two beasts of Revelation 13, (the Papacy and Protestant America) will unite and enforce Sunday laws.

Prophecy tells us that the whole world will follow in their footsteps and do the same.

Those who will obey and go along with this unbiblical worship will suffer the wrath of God manifested in the seven last plagues. (Revelation 16)

Where in the Bible does it say that the Sabbath is on Sunday?

Nowhere in the Bible does it say the Sabbath is on Sunday. God never changed the Sabbath, but people in their councils and by their own decisions made Sunday “holy”. 

They assume the holiness of Sunday to the resurrection of Jesus on that day. But the Bible does not support their teaching.

Christ established baptism as a sign of commemoration of His death, burial, and resurrection, and not Sunday worship.

Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death? 

Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life. 

Romans 6:3-4

Another false lead people are following to give honor to Sunday is found in Act 20:7. 

And upon the first day of the week, when the disciples came together to break bread, Paul preached unto them, ready to depart on the morrow; and continued his speech until midnight. 

Acts 20:7

This verse is often misunderstood and claimed to be the “evidence” of the Sabbath being changed.

Yet, upon close inspection, we find that the apostles were breaking bread every day. (Acts 2:46)

That day seemed to be what we call today Saturday evening. Back in those times, they were counting the days from sunset to sunset. (Leviticus 23:32)

It could not be the Sabbath, because Paul was getting ready for travel, an action you would not do on the Sabbath.

Besides that, we do not find a clear indication for the Sabbath to be changed.

First day of the week – Sunday in the New Testament

Important Fact: Did you know the first day (Sunday) of the week is mentioned only 8 times in the New Testament? Whereas the Sabbath is mentioned 60 times.

Matthew 28:1, Mark 16:2, 9, Luke 24:1, John 20:1, 19, Acts 20:7, 1 Corinthians 16:2.

Five of those verses deal with the resurrection of Jesus, when the women went to the tomb. (Matthew 28:1, Mark 16:2,9, Luke 24:1, John 20:1)

One deals with the apostles hiding from the fear of the Jews. (John 20:19)

We already talked about Acts 20:7.

And we are left with 1 Corinthians 16:2.

 Upon the first day of the week let every one of you lay by him in store, as God hath prospered him, that there be no gatherings when I come. 

1 Corinthians 16:2

Here, is not a worship service. 

Paul is talking about a collection for people that he had to bring to Christians on his way to Jerusalem. More details about this can be found in Romans 15:25-26.

Instead, this verse is totally against Sunday keeping, because Paul had to travel on that day, and the Sabbath is a day of rest.

So, it cannot be “evidence” for Sunday worshipping or Sabbath change. 

Does it matter what day the Sabbath is?

Of course. God created the Sabbath on the seventh day after He finished His creation. 

And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made. 

And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made. 

Genesis 2:2-3

Back then, the only people alive were Adam and Eve. There was no Jewish nation. 

And the Sabbath was made for everyone, not only for certain groups of people. (Mark 2:27)

We also find the importance of the Sabbath as the fourth commandment of God:

Remember the sabbath day, to keep it holy. 

Six days shalt thou labour, and do all thy work: 

But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates: 

For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it. 

Exodus 20:8-11 KJV 

Do Christians have to keep the Sabbath on Saturday?

Yes, if we want to follow Jesus and His teachings which are in His Word, we must keep the Sabbath on Saturday. 

Jesus and the apostles were an example of keeping the Sabbath on Saturday. (Luke 4:16), (Acts 13:42,44, 16:13, 17:2, 18:4)

If ye love me, keep my commandments. 

John 14:15 KJV

Did God change the Sabbath day to Sunday?

Nowhere in the Bible do we find any change of the Sabbath. He wrote the commandments in stone to show they are unchangeable. (Exodus 31:18)

No matter what arguments people may find, if it’s not in the Bible, then it is not from God. 

Never forget that we have a very cunning enemy which is an expert in deceiving. (Revelation 12:9)

The Bible says if we break one commandment, we are guilty of breaking them all. (James 2:10)

Did Jesus abolish the Sabbath?

Never. He emphasized the importance of the Sabbath and of doing good on this day. (Matthew 12:12)

Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. 

For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled. 

Matthew 5:17-18  KJV

Why do we worship on Sunday and not Saturday?

Unfortunately, many Christians have been misled by other people, priests, and pastors that Sunday is holy.

But they miss evidence from the Bible.

They too may have good intentions, but we must study diligently the Scriptures and see what God requires of us. 

And to rely less on others whether they are priests, pastors, etc. 

Sabbath Change

It first began with the Emperor of Rome, Constantine, in 321 AD, and later the Papacy followed in his footsteps. 

In 363, at the Council of Laodicea, the Papacy decided to change the Sabbath from the seventh day of the week to the first day.

This event was prophesied in Daniel 7:25.

This was not authorized by God, contrary to the claim of this Church that they are His representatives on Earth. 


We analyzed together that it is a sin to not observe the Sabbath on Saturday, the seventh day of the week as the Bible teaches. 

This is the fourth commandment of God, and He expects all of us to obey His commandments.

He does not hold us accountable for the time when we knew no better. Because He is loving, and kind, He understands our weaknesses and ignorance.

But once we discover more light from His Word, we must obey.

The Bible says there will be a time when observing the Sabbath on Sunday will be a sin.

Church and State union will take place according to Bible prophecy in Revelation 13.

They will cause all to worship on a false day that was not blessed and sanctified by God. (Revelation 13:15-18)

Everyone will need to make a decision. To obey God or man? 

Those who go along with this unbiblical religious system will suffer the wrath of God and will be lost forever. (Revelation 14:9-11)

On the other side, those who obey God and His commandments might pay with their lives. 

But they will be resurrected and given eternal life at the second coming of Jesus Christ. (Revelation 14:12, 20:4,6), (1 Thessalonians 4:16-17)

Do you want to be among those? Start obeying God’s laws today, including the Sabbath on the seventh day of the week.
