According to some, it says:

Isaiah 66:22-24: " For as the new heavens and the new earth which I will make shall remain before Me,' says the Lord, ........ 23 'And it shall come to pass that from one New Moon to another and from one S=A=B=B=A=T=H (Saturday) to another, all flesh shall come to worship before Me,' says the Lord. 24 'And they shall go forth and look upon the corpses of the men who have transgressed against Me ....... They shall be an abhorrence to all flesh." The word "Sabbath" in both the Old and New Testaments always refers to the seventh day of the week, Saturday. Sabbath is never translated as "Sunday" in the Bible. The "new heavens and the new earth" clearly refers to an age following a future event that has not yet occurred, the reshaping of the outer surface of the entire Earth by a global firestorm, the prophesied "lake of fire" that will incinerate the people that did not make it into God's kingdom. The worldwide Noachian Flood reshaped the Earth's surface with water, but fire, probably of nuclear intensity, will be used next time to purge the world of evil. 2 Peter 3:10,13: "........ the heavens will pass away with a great noise, and the elements will melt with fervent heat; ........ the earth ........ will be burned up. 13 ........ we, according to His promise, look for new heavens and a new earth in which righteousness dwells." In this future new age seventh day Saturday rest and worship will be observed, and it will be divinely enforced. Either a) the Lord is not telling the truth, or b) He changed the day of rest from Saturday to Sunday or allowed it to be changed to Sunday, then will change it back to Saturday in the future, or c) the original day of sanctified rest on Saturday memorializing the six days of creation was never abolished or changed and people are seriously sinning every time they labor or work on Saturday, excluding the noncommercial preparation of food for Sabbath meals. Since a is of course false because God cannot lie and b is illogical and silly, especially since there is no Scriptural evidence for it, only c must be valid. Only one of the previous choices is correct, and c is it. Verses commonly used by most Christians to help justify rest and worship on Sunday, the first day of the week, are the following, followed by more reasonable explanations which are also more in harmony with the entire Bible, as they of course should be: 1) Revelation 1:10: John said "I was in the Spirit on the Lord's Day .........." Some people believe that this means John was observing Sunday as a day of rest and had the vision on that day. However, the Bible nowhere says that the "Lord's Day" is the first day of the week, or Sunday. This verse in Revelation is the only place in the entire Bible where this term is used. The context of John's vision indicates that he was not referring to any particular day of the week. John said, instead, that the vision transported him into the future at a time referred to in the Bible as the "day of the Lord Jesus Christ" or "day of the Lord" or "day of Christ" (Jeremiah 46:10, 1 Corinthians 1:8, 5:5, 2 Corinthians 1:14, 1 Thessalonians 5:2, 2 Thessalonians 2:2, Acts 2:20, and 2 Peter 3:10). These terms refer to the day when man's rule ends and the millenium begins when Jesus returns in great power and glory, an event that will occur only one time. This is the central idea of the entire book of Revelation and the "Lord's Day" that John saw in his vision. 2) Acts 20:7: "Now on the first day of the week (Saturday night since Biblical days began at sunset), when the disciples came together to break bread, Paul, ready to depart the next day (Sunday at sunrise), spoke to them and continued his message until midnight." Today's English Version Bible, Phillips Modern English Bible, New English Bible, and several other New Testament translations record the disciples coming together to break bread on a Saturday night. Some people think that "breaking bread" refers to the bread and wine of the New Testament Passover service and conclude that this is a religious service on Sunday. Breaking bread, though, refers to dividing flat loaves of bread to be eaten at a regular meal. Breaking bread does not refer to a religious service. "It means to partake of food and is used of eating as in a meal .......The readers (of the original New Testament letters) could have had no other idea or meaning in their minds." (E. W. Bullinger, Figures of Speech Used in the Bible, 1991, pages 839-840). Additional proof occurs when, after Paul finished speaking for a while, they broke bread again and ate (verse 11). Luke 24:30, 35 and Acts 27:35 also mention breaking bread for the purpose of eating a meal. After talking most of the night, Paul departed at sunrise (Acts 20:11) to walk from Troas (Acts 20:6) to Assos (Acts 20:13), a distance of about 16 to 20 miles. Getting little if any sleep all night long and walking that far beginning at daybreak can hardly be described as a day of rest and worship, especially for a strict Saturday Sabbath keeping Pharisee such as Paul ! ! 3) 1 Corinthians16:2: "On the first day of the week let each one of you lay something aside, storing up as he may prosper, that there be no collections when I come." To interpret this as an account of a collection taken up during a supposed or imagined worship service is unjustified and unwarranted. Concerning this verse the Bible nowhere says that a church service was involved. This collection was a special one primarily for the members, called "the saints"(1 Corinthians 16:1) in Jerusalem (verse 3). No indication is given that the money was to be given to the Apostles for their living expenses. The collection was part of a more general relief effort that involved church members in Galatia (verse 1), Macedonia, and Achaia (Romans 15:25-26). This charitable collection effort could have been the one described in Acts 11:28-30 in which church members in Judea received assistance from the brethren in other areas at a time when a famine affected the whole world. In 1 Corinthians 16:2 Paul instructed the church members to "lay aside" and "store up" contributions "that there be no collections when I come" (1 Corinthians 16:2), not brought to a church service for collection. To believe that the above verse 2 involves a collection taken up during an imagined religious worship service is twisting that verse out of context. James Cardinal Gibbons was a Catholic educator and archbishop of Baltimore in the early 1900s. Commenting on the change from Saturday to Sunday worship, he said "You may read the Bible from Genesis to Revelation, and you will not find a single line authorizing the sanctification of Sunday. The Scriptures enforce the observance of Saturday, a day which we never sanctify. The Catholic Church correctly teaches that our Lord and his Apostles inculcated certain important duties of religion which are not recorded by the inspired writers. .....We must, therefore, conclude that the Scriptures alone cannot be a sufficient guide and rule of faith" (The Faith of Our Fathers, 1917, page 89). This archbishop admits that Sunday observance is nowhere authorized in the Bible and that Saturday is the only day Biblically sanctified. His justification for the change to Sunday is based on the assumption that the Catholic Church, (incredibly), has the authority to make its own laws concerning salvation, even after the Bible was written hundreds of years before the Catholic Church was formed. Emperor Hadrian, who ruled from 117 to 135 A.D. harshly persecuted Jews in the Roman Empire prohibiting Saturday Sabbath observance. This oppression apparently convinced many Christians in Rome at the time to abandon resting on Saturdays and to turn to Sundays, which is the day the sun worshipping Romans rested on. Within several hundred years Saturday rest by Christians was basically eliminated in the Roman Empire and replaced by Sunday. Although the Protestant Reformation produced doctrinal changes, Sunday observance has continued to this day in most Protestant churches. Protestant leaders generally justify Sunday rest and worship in honor of Jesus Christ's resurrection on Sunday (actually on Saturday night). Honoring Jesus in such a way of course seems very nice, but unfortunately, it involves entering dangerous territory, usurping divine authority to decide what is sacred and what is not, tampering with ancient, sanctified laws. In simple terms it is a very, very big no-no, even a capital offense. No other verses exist in the Bible mentioning anything even remotely resembling worship services on Sunday. The New Testament was written decades after the resurrection of Jesus Christ, and not a single verse indicates the day of rest was changed from Saturday to Sunday.

but I hold to the idea in

Mar 2:28 ThereforeG5620 theG3588 SonG5207 of manG444 isG2076 LordG2962 alsoG2532 of theG3588 sabbath.G4521 .

This tells me that God is more interested in our hearts of worship rather than the time or place in which we worship. As it is written in the Old Testament people were required to worship in the "Temple", but remember what Jesus said to the woman at the well

Joh 4:21 Jesus declared, "Believe me, woman, a time is coming when you will worship the Father neither on this mountain nor in Jerusalem.

Even if we are wrong about the day we are saved by Grace and not by our actions, and it is scriptural that "God looks at the Heart" and if our heart is right then how can our actions be wrong? It seems to be more important to spread the "Good News" about Jesus Christ to everyone than to argue about things that are of lesser importance. I hope this conveys my beliefs and gives you some thoughts. Through prayer and seeking God's wisdom we can receive the answers if God wants us to have them. My prayer is that God gives me more each and every day, and if He convicts me that we are doing it all wrong then I will anxiously change. I'm glad that you are still looking into all things, as it says in Scripture "Study to show yourself approved by God, a workman that needeth not be ashamed".
