1. Paul says it is the TEN in Eph 6:1-2 where we find it is that unit of Law where "honor your father and mother" is the first commandment with a promise.
Paul said nothing here about the 4th commandment. Paul simply said - Children, obey your parents in the Lord, for this is right. "Honor your father and mother," which is the first commandment with promise: Paul never once commands Christians to keep the sabbath day under the new covenant.
. Christ quotes from the TEN in Matt 19 when saying that we are to "keep the Commandments" and then is asked "which ones?"
Jesus quotes from the 10, but He doesn't mention the 4th commandment here. Instead, Jesus said, ‘You shall not murder,’ ‘You shall not commit adultery,’ ‘You shall not steal,’ ‘You shall not bear false witness,’ 19 ‘Honor your father and your mother,’ and, ‘You shall love your neighbor as yourself.’ Even if all 10 were still in force here under the old covenant it's because Jesus had not yet died and the new covenant had not yet been ratified. (Matthew 26:28; Hebrews 9:16)
Jesus showed the rich young ruler how short he falls of keeping the first commandment (Exodus 20:3) which is the first of the two great commandments (Deuteronomy 6:5; Matthew 22:37). The rich young ruler confidently and (self righteously) declared that he has kept the commandments from his youth up and qualified for heaven under those terms. That sounds familiar. Yet Jesus knew the man's wealth had become his idolatrous god, which kept him from believing in Jesus unto salvation. (John 3:15,16,18)
3. leading scholarship in all major Christian denominations today affirm that the TEN are included in the moral law of God written on the heart under the New Covenant - because of texts such as the ones just given.
Those texts do not confirm your argument no matter how many scholars you say agree with that. NOWHERE under the new covenant are Christians commanded to keep the sabbath day holy. Period.
When stating that the Bible Sabbath of the Ten Commandments is part of the moral law of God and is applicable to all mankind I am stating a Bible detail so obvious that all major Christian denominations agree - the TEN are part of the moral law of God written on the heart (see the "Baptist Confession of Faith" sectn 19 and the "Westminster Confession of Faith" section 19 and the Catholic Catechism on the TEN Commandments... etc)
Hmm... Apparently not all Baptists agree with your argument on the sabbath.
Sabbath or Sunday?
Acts 20:7; 1 Corinthians 16:2
Christians are not required to observe the Sabbath, but could we explain why to Sabbath-keepers? I want to share 11 reasons why we gather for worship in Sunday, the first day of the week, the Lord’s Day.
1. The Saturday Sabbath was given to Israel.
It was a sign of the Mosaic Covenant [
Ex. 31:15-17], “Six days may work be done; but in the seventh is the Sabbath of rest, holy to the Lord; whosoever doeth any work in the Sabbath Day, he shall be put to death. The children of Israel shall keep the Sabbath, to observe the Sabbath throughout their generations, for a perpetual covenant. It is a sign between me and the children of Israel forever: for in six days the Lord made heaven and earth, and on the seventh day He rested, and was refreshed.” The Hebrew word means “to cease,” the cessation of work because God rested after the creation and a reminder of deliverance from Egypt. Christians are under the New Covenant and are not required to observe the Sabbath. “Who hath made us able ministers of the New Covenant,”
2 Cor. 3:6.
2. There is no commandment in the New Testament for Christians to observe the Sabbath. [Ex. 20:8-11]
The 4th commandment is not mentioned in the New Testament. Why? It was for Israel.
Col. 2:16, “Let no man therefore judge you in meat, or in drink, or in respect of a holy day, or of the new moon, or of the Sabbath days: Which are a shadow of things to come; but the body [substance] is of Christ.” The shadow is no longer binding on us since the substance has come [Jesus].
3. The O.T. neither commanded the Gentile nations to observe the Sabbath nor condemns them for failing to do so.
This is proof the Sabbath was given to Israel.
4. There is no record in the Bible of anyone observing the Sabbath before the time of Moses.
5. The Jerusalem Council in Acts 15 did not impose Sabbath-keeping on the Gentile believers.
The issue was being circumcised to be saved. There ruling was in
Acts 15:24, “Some trouble you by saying you must be circumcised and keep the Law: to whom we gave no such command.”
6. The New Testament warns Gentile believers about many sins, but never about breaking the Sabbath.
7. Paul rebukes the Galatians for thinking that God expected them to observe special days, such as the Sabbath.
Gal. 4:10-11, “You observe days, and months, and seasons, and years. I am afraid for you, lest I have labored for you in vain.”
8. To observe the Sabbath was to be a matter of personal preference until they understood their Christian liberty.
Romans 14:5, “One man esteems one day above another: another esteems every day alike. Let every man be fully convinced in his own mind.” The weaker brother is to grow in his Christian liberty.
9. The book of Acts and the writings of early church fathers make it clear that the early church met for worship on Sunday.
Why no rebuke from the Lord?
10. Christ’s resurrection and His post-resurrection appearances were on Sunday and the Holy Spirit came on Sunday.
11. The Sabbath commemorates the Father’s finished work of creation, while the Lord’s Day commemorates Christ’s finished work of redemption, the “new creation.”
God worked for six days and rested, the Son suffered six hours and rested. Jesus fulfilled the Sabbath and we cease from works and rest in Him.
Sabbath or Sunday?
In regards to the Westminister Confession of faith, like Baptists, not all other Protestants are on the same page with you, so using your argument does not settle the issue.
It doesn't sound to me like Catholics are on the same page with you either.
From the catholic.com website - Some religious organizations (Seventh-day Adventists, Seventh-Day Baptists, and certain others) claim that Christians must not worship on Sunday but on Saturday, the Jewish Sabbath. They claim that, at some unnamed time after the apostolic age, the Church “changed” the day of worship from Saturday to Sunday.
However, passages of Scripture such as Acts 20:7, 1 Corinthians 16:2, Colossians 2:16-17, and Revelation 1:10 indicate that, even during New Testament times, the Sabbath is no longer binding and that Christians are to worship on the Lord’s day, Sunday, instead.
The early Church Fathers compared the observance of the Sabbath to the observance of the rite of circumcision, and from that they demonstrated that if the apostles abolished circumcision (Gal. 5:1-6), so also the observance of the Sabbath must have been abolished.
What the Early Church Believed: Sabbath or Sunday?
I have two customers on my mail route (one is a SDA and and the other is an Armstrongite (attends the Worldwide Church of God) and they both told me that I need to tell my employer that I can't work on Saturday because it's the sabbath day and they both implied that if I continue to work on Saturday I won't be saved for breaking one of God's 10 commandments. Do you agree with them? This is the type of legalism that results from turning keeping the sabbath day into a legalist prescription for Christians under the new covenant.
Those who insist that sabbath keeping is a command for Christians today can't even decide on what all that entails. I understand what it entailed under the old covenant, which has been made obsolete by the new covenant. (Hebrews 8:6-13) Sabbath keeping with all it's rules and regulations, was
part of a covenant with Israel (Exodus 16:23, 29; 31:12-18; 35:1-3; Leviticus 19:30; 23:2-3, 32; Numbers 15:32-36; 28:1-10; 29:39-40; I Chronicles. 23:30-31; II Chronicles 31:2-4; Isaiah 1:13; Amos 8:5; Nehemiah 10:31) that is
not binding on Christians under the new covenant. (Colossians 2:16-17)
