Saturday or Sunday? -About Sabbath, the Fourth Commandment

What day is Lord's day?

What day is Lord's day which Christian say?

What day is Lord's day which Jesus says?

Same day or not?  Let's find it out

Jesus is the Lord of the Sabbath

There are those who are not willing to be invited to a wedding ceremony or other events on Sunday. They have to go to church. They consider "observing the Lord's Day" as their first value and worship on Sundays. It is quite praiseworthy thing that they value worship. However, there is something wrong. Biblically, the worship day is not Sunday but Saturday. Those who mention “the Lord’s Day” frequently cite the following verses:

On the Lord's Day I was in the Spirit… (Revelation 1:10)
They insist that the Lord’ Day is Sunday, knowing the fact that there isn’t a single verse about worship on Sunday. Then, when is the Lord’s Day?
For the Son of Man is Lord of the Sabbath. (Matthew 12:8; Mark 2:28; Luke 6:5)
Jesus is the Lord of the Sabbath. Therefore, the “Sabbath” is the Lord’s Day. You know, the Sabbath is Saturday in our current calendar system. We just need to worship on Saturday because God commanded us to give services on Saturday. Why do they dare do against the will of God by inventing Sunday?
Remember the Sabbath day by keeping it holy (Exodus 20:8)
God commanded God’s people to keep the Sabbath holy as the Fourth Commandment. He has never said that Sunday is “My day.” Please remember: the Sabbath is the Lord’s Day.
