Sunday worship is not the Sabbath Day because the biblical Sabbath Day must be held on Saturday, the seventh day of the week. Because Sunday worship is a practice of people for a long time, they hardly insist that the Sabbath Day should be kept on Sunday. There is nowhere in the Bible saying that the biblical Sabbath Day is Sunday, nor did God ever say that the Sabbath Day is Sunday worship.
Revelation 22:18 I warn everyone who hears the words of the prophecy of this scroll: If anyone adds anything to them, God will add to that person the plagues described in this scroll.
We cannot add or subtract to the perfect words of God. Faith is obedience. How can we say we have faith when we do not fully obey the absolute words of God? Among words of God is the Sabbath Day; therefore, we should observe it on the correct day without adding to or subtracting from it.
The Origin of Sunday Worship: Excerpts From Christian History Books
The origin of Sunday worship is man-made. The Roman Emperor, Constantine, ordered to make Sunday as a rest day and it became a custom to be the Sabbath day. It’s not God’s will and command to keep the Sabbath Day on Sunday. Below are several highlights from Christian History Books about the how Sunday worship originated.
It is probable that Constantine set out with a deliberate intention to favour the Church, but even it that were so, it was necessary to placate the pagans. Consequently, the policy agreed upon at Milan was a recognition of the complete parity of religions. But as the reigned progressed Constantine supported the Christians more and more, and one can only conclude that his aim was to make of Christianity the cement that was to bind together the whole Empire…
But perhaps the most significant evidence of this policy is to be found in the decree of 321 regulating Sunday observance. That ordinance puts the Lord’s Day on the same level of observance as the pagan festivals and marks it by the cessation of work. It is noteworthy, however, that the day is described by no Christian appellation but simply as dies venerabilis solis, and no pagan could well object to that.
The rescript commanding the celebration of the Christian Sabbath bears no allusion to its peculiar sanctity as a Christian institution. It is the day of the Sun, which is to be observed of the general veneration. The courts were to be closed, and the noise and tumult of public business and legal litigation were no longer to violate the repose of the sacred day.
All judges and city people and the craftsmen shall rest upon the venerable day of the sun. Country people, however, may freely attend to the cultivation of the fields, because it frequently happens that no other days are better adapted for planting the grain in the furrows or the vines in trenches. So that the advantage given by heavenly providence may not for the occasion of a short time perish.
Are We Blessed on Sunday Worship, Which is Not Biblical?
Just because we worship God does not mean that we are already blessed. There is a worship that brings curse and a worship that grants us God’s blessing. In Matthew 7:21-23, it is written that only those who do God’s will can enter the kingdom of heaven. Then, is Sunday worship a will of God? It is not God’s will.
Exodus 20:8-11 Remember the Sabbath day by keeping it holy. Six days you shall labor and do all your work, but the seventh day is a sabbath to the Lord your God. On it you shall not do any work, neither you, nor your son or daughter, nor your male or female servant, nor your animals, nor any foreigner residing in your towns. For in six days the Lord made the heavens and the earth, the sea, and all that is in them, but he rested on the seventh day. Therefore the Lord blessed the Sabbath day and made it holy.
The Sabbath Day is the seventh day, Saturday. Is not astonishing that so-called Christians who believe in God keep Sunday worship which is not a will of God, yet they want to be saved? Let us guarantee our salvation by keeping the command of God with firm and absolute faith.
