Saturday or Sunday
God instituted the seventh-day Sabbath (Saturday) at creation, “Thus the heavens and the earth were finished, and all the host of them. And on the seventh day God ended 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 2:1-3). The weekly seventh-day Sabbath has often been considered for the Jewish dispensation, but the Bible declares that it was instituted more than two thousand years before the first Israelite was born.
God blessed the seventh day because He created the world in six days and rested on the seventh. The Sabbath was the birthday and the memorial of the world. The Sabbath can’t be changed because it points backward to a specific act. In the same manner, a person’s birthday can’t be changed because it is a memorial of his birth. The seventh day Sabbath identifies the true God and His claim of ultimate sovereignty as the Creator. No other day can fit God’s purpose.
The Fourth Commandment states: “Remember the Sabbath day, to keep it holy. Six days you shall labor and do all your work, but the seventh day is the Sabbath of the Lord your God. In it you shall do no work: you, nor your son, nor your daughter, nor your male servant, nor your female servant, nor your cattle, nor your stranger who is within your gates. For in six days the Lord made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. Therefore the Lord blessed the Sabbath day and hallowed it” (Exodus 20:8-11).
Most of the Ten Commandments begin with the same words: “Thou shalt not,” but the fourth commandment starts with the word, “Remember” (Exodus 20:8-11). Why is this one different? Because God was commanding His children to call something to memory which already existed but had been forgotten.
Christ Didn’t Abolish His Law
It does matter that we should worship on the seventh day (Saturday) because it was God’s commanded. What was the original sin of Adam and Eve? Eating from THE forbidden TREE. What was so evil about eating from that tree? Adam and Eve’s act was an act of disobedience to God’s command. That one sin resulted in the destruction of the human race and planet Earth. And it resulted in the death of God’s only Son on the cross (John 3:16).
God is very serious about His commands. Jesus said, “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). And He added, “It is easier for heaven and earth to pass, than one tittle of the law to fail” (Luke 16:17).
God’s Law Still Binding
The great Lawgiver Himself reaffirmed His law that He gave earlier as binding upon His followers, and announced that anyone who should attempt to disregard it either by precept or by example would “in no case enter into the kingdom of heaven” (Matthew 5:20). And the Word of God can’t change. It “shall stand for ever” (Isaiah 40:8).
The claim that some give that by fulfilling the moral law Christ canceled it is not in harmony with the context of Christ’s statement. By fulfilling the law Christ simply “filled” it “full” of meaning—by giving men an example of full adherence to the will of God, so that the same law “might be fulfilled in us” (Romans 8:3, 4).
The word “Sunday” is not mentioned in the Bible. But the phrase “first day” is mentioned only eight times: Matthew 28:1; Mark 16:2; Mark 16:9; Luke 24:1; John 20:1; John 20:19; Acts 20:7; 1 Corinthians 16:2. But none of these verses teach that “the first day of the week” Sunday is a holy day of rest or being sacred. In none of these verses can we find a single hint of Bible authority for Sunday sacredness! Sunday observance is a made-made institution.
