From The Bible knowledge Commentary:
2:15-17. By fulfilling the demands of the Law, Christ disarmed the demonic powers and authorities (cf. 1:16; 2:10), triumphing over them (cf. 2 Cor. 2:14). As a result believers are delivered from these evil powers which inspire legalistic rules about foods and festivals. No one should judge you by what you eat or drink because Christians are free from the Law’s legalistic requirements (such as those in Lev. 11; 17; Deut. 14). God does not condemn those who eat everything (Rom. 14:1-4). In fact, God says that all foods may be eaten since they were “created to be received with thanksgiving by those who believe and who know the truth” (1 Tim. 4:3). The teaching that forbids this, Paul wrote, is “taught by demons” (1 Tim. 4:1) whom Christ has disarmed (Col. 2:15). This liberation of believers pertains also to festivals such as a New Moon celebration or a Sabbath Day (cf. Gal. 4:10). Those who would bring Christians under the bondage of the Law make artificial distinctions between the “ceremonial” and “moral” law, and so they say the Sabbath has not passed away. That this is false can be seen from the following: (1) The Sabbath command is the only one of the Ten Commandments not repeated in the New Testament. (2) The early believers, following Christ’s resurrection and appearance on Sunday (Mark 16:1; John 20:1), met on Sundays (Acts 20:7; 1 Cor. 16:2). (3) The Bible nowhere distinguishes between the so-called “moral” and “ceremonial” laws (this distinction was not made before the 13th century a.d.) (4) This Colossian passage explicitly condemns those who command Sabbath obedience. (5) As Paul put it, the Old Testament Law (including the Sabbath) was only a shadow of the things that were to come. The reality or “substance” (sōma, lit., “body”), however, is to be found in Christ (cf. Heb. 8:5; 10:1). What the Old Testament foreshadowed, Christ fulfilled (cf. Matt. 5:17; Rom. 8:3-4). A “shadow” (skia) is only an image cast by an object which represents its form. Once one finds Christ, he no longer needs to follow the old shadow.
Now, it you want to make your claim of keeping the sabbath, you need to look at this first.
The year 2014, Gregorian calendar (ours) is the year 5774 on the Jewish calendar.
From Wikipedia:
Because of the roughly eleven-day difference between twelve lunar months and one solar year, the length of the Hebrew calendar year varies in the repeating 19-year Metonic cycle of 235 lunar months, with the intercalary month added according to defined rules every two or three years, for a total of seven times per 19 years. Even with this intercalation, the average Hebrew calendar year is longer by about 6 minutes and 25+25/57 seconds than the current mean solar year, so that every 224 years, the Hebrew calendar will fall a day behind the current mean solar year; and about every 231 years it will fall a day behind the Gregorian calendar year.
Anyone trying to keep the Sabbath on the Gregorian calendar isn't keeping it at all! One would have to take off of work in the middle of the week to keep it!
All laws & prophecies of the OT hinge on the Jewish calendar. Therefore, those fussing about changing from Saturday to Sunday is a "changing of times" is totally unaware it was changed already by the changing of the calendars! If Sunday-goers are sinning, so are the sabbath-keepers of the Gregorian calendar!
Then there's the rest of the laws concerning the Sabbath (seventh) day:
1. No work done at all (Ex. 20: 10; Lev. 23: 3; Jer. 17:21-22). No watering the lawn, no working in the yard, no hobbies, no surfing, no fixing flat tires, etc. By law if a person did not stop all types of activity in honor of the Sabbath, he was breaking the law. In Numbers 15:32-36 a man was caught collecting sticks on the Sabbath, and he was stoned to death.
2 No kindling of a fire (Ex. 35:3). No fellowship cookouts or barbecues. You can't go into a restaurant and get a hamburger that's been flame broiled, you can't cook eggs, or pancakes in the morning because you'd be kindling a fire for cooking. To drive a car would be to "kindle a fire" In the combustion chamber of your engine.
3. No traveling at all (Ex. 16:29). Later the Jews added to this law, allowing only a half mile of travel on the Sabbath which we see observed in the NT. But the pure law says "stay at home." Actually, If you kept this part of the law, you could not travel to your church gathering unless it was less than one-quarter mile away from home. If you had an emergency you could not drive to the hospital.
4. No trading (Amos 8:5). If you happened to need gas to get to church service, you could not "trade" money for gasoline. You would not be allowed to buy a cassette tape of that morning's message or a book at the store. There is to be No exchanging of money for goods. If you worked with stocks and you needed to sell you couldn’t.
5. No marketing (Neh. 10:31; 13:15,19). Make sure you do no shopping whatsoever. You can't buy any ice cream for dessert after dinner or anything else. If you run out of food or drink at home you can’t go out to purchase any, you can’t even by a stick of gum.
6. A holy assembly with double the daily offering along with the other offerings. In other words, you are to give twice as much on the Sabbath (Num. 28:9).Do we practiced this today In compliance with Old Testament law. Do Sabbatarian's really practice the law? I have yet to see people go to Shabbat and give twice as much each week.
7. New showbread In the holy place (Lev. 24:8). Of course this cannot be done today since there is no temple, so this part of the Sabbath cannot be followed by the church. The fact Is the Sabbath was not made for the gentiles, but for the Jews and their generations (Ex. 31:12-17). It's a law given between God and the Jews.
8.The last part of the requirements for keeping the Sabbath day law Is the penalty for breaking It. DEATH
So, which of you are keeping the Shabbat of the 10 commandments?
