I ignore Sabbatarian legalism applied to the 7th or the 1st day of the week. I live under the New Covenant! I reject the idea of calling Sunday the "Christian Sabbath".
The why do you meet on Sundays which is not in scripture?
1. Nowhere in the New Covenant is there a command for Christians, New Covenant believers, to observe the sabbath. Jesus did not command its observance for Christians.
2. The sabbath is not mentioned in the Bible until you come to Moses and the Mosaic Law.
3. God worked 6 days and rested on the 7th day making it holy. Sunday is a rest day after 6 days of work. There is not a specific day of the week commanded in the New Covenant as the rest day, but Sunday, being the first day of the week when Jesus Christ arose from the grave, it is honored. It is the Lord's Day just as the communion is the Lord's Supper.
4. I am not an Israelite
and the sabbath was given to Israel alone in the law, to no other nations -
"And what great nation is there, that has statutes and ordinances so righteous as all this law which I set before you this day?
" (Deut 4:8, RSV)
a. The law, including the "sabbath", was given on that particular day or time.
b. It was given to Israel alone, no other nations
C. Acts chapter 15 makes it clear Gentiles were not put under the Mosaic Law
5. Jesus came to fulfil the law and complete the law's requirements, Matt. 5:17,18
Jesus "abolished" the law, "by abolishing in his flesh the law of commandments and ordinances, that he might create in himself one new man in place of the two, so making peace
,"(Eph 2:15, RSV)
Jesus nailed it to the cross, "having canceled the bond which stood against us with its legal demands; this he set aside, nailing it to the cross
. (Col 2:14, RSV) Read 2 Cor. 3:7-11
Compare the following two verses, one NT and the other OT -
"In speaking of a new covenant he treats the first as obsolete. And what is becoming obsolete and growing old is ready to vanish away
." (Heb 8:13, RSV)
"And he was there with the LORD forty days and forty nights; he neither ate bread nor drank water. And he wrote upon the tables the words of the covenant, the ten commandments.
" (Exod 34:28, RSV)
** The sabbath was in the "ten commandments" that vanished away in Christ.
6. Paul specifically named the "sabbath" as something we are not to permit ourselves to be judged about, "Therefore let no one pass judgment on you in questions of food and drink or with regard to a festival or a new moon or a sabbath"
. (Col 2:16, RSV)
"Who are you to pass judgment on the servant of another? It is before his own master that he stands or falls. And he will be upheld, for the Master is able to make him stand. One man esteems one day as better than another, while another man esteems all days alike. Let every one be fully convinced in his own mind.
" (Rom 14:4-5, RSV)
From Fausset's Bible Dictionary -
"The early church met to break bread on the first day (Act 20:7); it was the day for laying by of alms for the poor (1Co 16:2). No formal decree changed the Sabbath from the seventh to the first day; this would only have offended the Jews and weak Christians.
At first both days were kept. But when Judaizing Christians wished to bring Christians under the bondage of the law, and the Jews became open antagonists of the church, the observance of the Jewish Sabbath was tacitly laid aside, and the Lord's day alone was kept
; see Col 2:16. Moses, the law's representative, could not lead Israel into Canaan. The law leads to Christ, there its office ceases: it is Jesus, the Antitype of Joshua, who leads us into the heavenly rest (Heb 4:8-9)."
