Here is what the Apostolic Council of Jerusalem, the first Church council in the history of the Church, had to say about Gentile converts to Christianity............. So, yes, such things really are matters of conscience. These things are expressly, explicitly stated in Scripture.
Your argument here is stating that Acts 15 is teaching that keeping God's 4th commandment which is one of God's 10 commandments are a matter of conscience? So in your view can all the other 10 commandment be kept now as a matter of conscience? Can we now according to you lie, steal. go and commit adultery or kill our fellow man, take God's name in vain or now worship other God's of which are also Gods' 10 commandments? I hope you can now see what your arguing here which is simply not biblical.
So the Apostolic Council established "no further burden" as it pertains to certain matters of Gentile conversion to Christianity, then these things. It's not about strict "law" upon such converts; but rather the gentle guidance of the Church for new converts, which we see St. Paul himself exercising in his capacity as apostle in his letters to the churches.
Had it been expected that Gentiles should be circumcised, observe the Sabbath, any of the Jewish feasts, follow kashrut, etc then certainly the Apostolic Council would have said so. But, on the contrary, the Council says nothing about these things, but explicitly states that Gentiles were not to be burdened with the rites and practices of Judaism. Indeed, earlier in Acts ch. 15 St. Peter addresses the presbyters of the Jerusalem Church and the other apostles gathered together there, "Now, therefore, why are you putting God to the test by placing a yoke on the neck of the disciples that neither our fathers nor we have been able to bear?" (Acts of the Apostles 15:10). This is an explicit statement that it was wrong to place the Torah upon Gentile converts. Thus the Council ruled to place no burden, no yolk, upon Gentile converts except these things to help guide new converts away from Paganism to a deeper Christian faith.
There exists no commandment from God for Christians to observe the Sabbath. Can one observe the Sabbath? Yes, but only as a choice of free conscience, not as a divine command from God to be obeyed.
"As for the one who is weak in faith, welcome him, but not to quarrel over opinions. One person believes he may eat anything, while the weak person eats only vegetables. Let not the one who eats despise the one who abstains, and let not the one who abstains pass judgment on the one who eats, for God has welcomed him. 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 Lord is able to make him stand.
One person esteems one day as better than another, while another esteems all days alike. Each one should be fully convinced in his own mind. The one who observes the day, observes it in honor of the Lord. The one who eats, eats in honor of the Lord, since he gives thanks to God, while the one who abstains, abstains in honor of the Lord and gives thanks to God." - Romans 14:1-6
And indeed, those who presume to judge others, placing the yolk of the Torah upon converts to Christianity are rebuked and condemned by the apostles,
"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. These are a shadow of the things to come, but the substance belongs to Christ. Let no one disqualify you, insisting on asceticism and worship of angels, going on in detail about visions, puffed up without reason by his sensuous mind, and not holding fast to the Head, from whom the whole body, nourished and knit together through its joints and ligaments, grows with a growth that is from God." - Colossians 2:16-19
"But when Cephas came to Antioch, I opposed him to his face, because he stood condemned. For before certain men came from James, he was eating with the Gentiles; but when they came he drew back and separated himself, fearing the circumcision party. And the rest of the Jews acted hypocritically along with him, so that even Barnabas was led astray by their hypocrisy. But when I saw that their conduct was not in step with the truth of the gospel, I said to Cephas before them all, 'If you, though a Jew, live like a Gentile and not like a Jew, how can you force the Gentiles to live like Jews?'" - Galatians 2:11-14
"O foolish Galatians! Who has bewitched you? It was before your eyes that Jesus Christ was publicly portrayed as crucified. Let me ask you only this: Did you receive the Spirit by works of the law or by hearing with faith? Are you so foolish? Having begun by the Spirit, are you now being perfected by the flesh? Did you suffer so many things in vain—if indeed it was in vain? Does he who supplies the Spirit to you and works miracles among you do so by works of the law, or by hearing with faith— just as Abraham “believed God, and it was counted to him as righteousness”?
Know then that it is those of faith who are the sons of Abraham. And the Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel beforehand to Abraham, saying, “In you shall all the nations be blessed.” So then, those who are of faith are blessed along with Abraham, the man of faith." - Galatians 3:1-9
There is no righteousness found in commandment keeping. There is only the righteousness of Jesus Christ which is through faith.
The burden of the Torah is not for us, it was given through Moses to point the way to Christ, as Paul says, like a harsh taskmaster which corrected us with many beatings until Christ came (Galatians 3:24). Paul calls the Torah a paidagogos. In the ancient Greco-Roman world a paidagogos was a slave given the task to rear children in the household, it was the paidagogos' job to discipline unruly children, and help teach them the basics. The Torah was harsh, because the children were disobedient, hostile, and violent; but the job of the paidagogos is done with. Israel has reached maturity from childhood to adulthood in Jesus Christ, who is the telos of the Torah and the Prophets--their end, goal, and the purpose for their existence, to lead to, point to, direct us toward the bigger, better, grander reality of Jesus Christ our Lord. And thus He says He did not come to abolish, but to fulfill. To make full all the righteousness required, by His own perfect righteous life, His death, and resurrection. That by His fullness we are the benefactors of His righteousness, which we have as grace and gift from God, through faith, by the word and power of the Gospel.
The Sabbath has nothing to do with the Gospel, and those who make the Sabbath part of the Gospel preach a false gospel, and therefore stand condemned, under anathema, by these words of the holy apostle,
"I am astonished that you are so quickly deserting him who called you in the grace of Christ and are turning to a different gospel— not that there is another one, but there are some who trouble you and want to distort the gospel of Christ. But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed. As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you received, let him be accursed." - Galatians 1:6-9-CryptoLutheran
Let's now look at what Acts 15 is really saying and the other scriptures you left out that do not support your view here that Acts 15 is saying that Gods' 10 commandments are not a requirement for Christian living for all believers....
WHAT IS THE QUESTION THAT ACTS 15 IS CONSIDERING?
ACTS 15:1-21
[1], And certain men who came down from Judea taught the brethren, and said, E
XCEPT YOU BE CIRCUMCISED AFTER THE MANNER OF MOSES YOU CANNOT BE SAVED.
NOTE: ACTS 15:1 is the question that needs to be answered and the topic of conversation and CONTEXT of the chapter of ACTS 15. Here we have Jewish believers coming to Paul and Barnabas saying if the new GENTILES believers are not circumcised and made proselytes then they cannot be saved. This is the chapter context and issue of contention.
[2], When therefore Paul and Barnabas had no small dissension and dispute with them,
THEY DETERMINED THAT PAUL AND BARNABAS AND CERTAIN OF THEM SHOULD GO UP TO JERUSALEM UNTO THE APOSTLES AND ELDERS ABOUT THIS QUESTION.
NOTE: ACTS 15:2 Which question? Weather your salvation depends on being CIRCUMCISED.
They then traveled to Jerusalem about this question to determine if new gentile believers needed to be
CIRCUMCISED in order to be saved. Once they got to Jerusalem, the question was then asked and the discussion continued with the Pharisees stating their case first..
[5], But there rose up certain of the sect of the Pharisees who believed, saying, It is needful to circumcise them, and to command them to keep the law of Moses.
NOTE: KEEP in mind here the question was never over if gentile believers should obey God's 10 Commandments but to keep the Shadow laws of Moses, in this case CIRCUMCISION as a means of salvation. CIRCUMCISIONS is from the law of MOSES not God’s 10 Commandments written by God on two tables of stone.
[6],
And the apostles and elders came together TO CONSIDER THIS MATTER.
NOTE: Again the topic of discussion and chapter CONTEXT that is being considered is the question stated in ACTS 15:1 which was IS CIRCUMCISION A REQUIREMENT OF SALVATION?
[7], And when there had been much disputing, Peter rose up, and said unto them, Men and brethren, you know how that a good while ago God made choice among us, that the Gentiles by my mouth should hear the word of the gospel, and believe.
[8], And God, who knows the hearts, bore them witness, giving them the Holy Spirit, even as he did unto us;
NOTE: After much discussion between the Apostles, Peter then rose up showing that God gave the gentile believers the Holy Spirit being UNCIRCUMCISED.
[9], And put no difference between us and them, purifying their hearts by faith.
[10], Now therefore why test God, to put a yoke upon the neck of the disciples, which neither our fathers nor we were able to bear?
[11], But we believe that through the grace of the Lord Jesus Christ we shall be saved, even as they.
NOTE: They came to the conclusion then that salvation is not by being circumcised but be what circumcision pointed to. A new heart by faith. This is made plain latter in other scripture written by PAUL here...
ROMANS 2:25-29 [25] For circumcision verily profits, if you keep the law: but if you are a breaker of the law, your circumcision is made uncircumcision. [26], Therefore if the uncircumcision keeps the righteousness of the law, shall not his uncircumcision be counted for circumcision? [27], And shall not uncircumcision which is by nature, if it fulfils the law, judge you, who by the letter and circumcision do transgress the law? [28],
FOR HE IS NOT A JEW, WHO IS ONE; NEITHER IS THAT CIRCUMCISION, WHICH IS OF THE OUTWARD FLESH: [29],
BUT HE IS A JEW WHICH IS ONE INWARDLY; AND CIRCUMCISION IS THAT OF THE HEART, IN THE SPIRIT AND NOT IN THE LETTER; WHOSE PRAISE IS NOT OF MEN BUT OF GOD.
If ACTS 15 was talking about the 10 Commandments then Paul's writings to the Corinthian believers do not make any sense and has Paul in contradiction to your interpretation when he says to the Corinthian believers.
1 CORINTHIANS 7 [19]
CIRCUMCISION IS NOTHING, AND UNCIRCUMCISION IS NOTHING, BUT THE KEEPING OF THE COMMANDMENTS OF GOD.
I believe Paul makes it very clear in 1 Corinthians 7:19 that Acts 15 was never over the topic are the 10 commandments a requirement for Christian living. The scripture above is a contradiction of how some interpret the outcome of ACTS 15. You do not believe Dan, that we are now free to break any of God's 10 Commandments now do you?
[12], Then all the multitude kept silence, and listened to Barnabas and Paul declaring what miracles and wonders God had done among the Gentiles by them.
[13], And after they had held their peace, James answered, saying, Men and brethren, hearken unto me:
[14], Simeon has declared how God at the first did visit the Gentiles, to take out of them a people for his name.
[15], And to this agree the words of the prophets; as it is written,
[16], After this I will return, and will build again the tabernacle of David, which is fallen down; and I will build again the ruins thereof, and I will set it up:
[17], That the rest of men might seek after the Lord, and all the Gentiles, upon whom my name is called, says the Lord, who does all these things.
[18], Known unto God are all his works from the beginning of the world.
[19],
THEREFORE MY JUDGMENT IS THAT WE TROUBLE NOT THEM WHO FROM THE GENTILES ARE TURNED TO GOD:
[20],
BUT WRITE UNTO THEM THAT THEY ABSTAIN FROM THE DEFILEMENT OF IDOLS, FORNICATION AND THINGS STRANGLED AND FROM BLOOD.
NOTE: JAMES conclusion is that new Gentile believers should not be troubled with CIRCUMCISION as a requirement of salvation which was the matter being considered and the question being discussion as shown in *ACTS 15:1-2; ACTS 15:6 but asks them to abstain from idols, fornication and from things strangled and from blood.
[21],
FOR MOSES OF OLD TIME HAS IN EVERY CITY THEM THAT PREACH HIM, BEING READ IN THE SYNAGOGUES EVERY SABBATH.
NOTE: The reason why JAMES sends this letter to the new Gentile believers is that they would continue learning God's WORD
EVERY SABBATH.
……………
CONCLUSION So the conclusion of the matter with CONTEXT added back in is fould in v19-20 We are not to trouble the new gentile believers with CIRCUMCISION as a means of salvation. They are new converts that will learn more about GOD'S WORD when? EVERY SABBATH. In the meantime you should abstain from anything offered to idols, and from blood, and from things strangled, and from fornication.
NOPE nothing written about the 10 Commandments being abolished in this chapter. Here is what PAUL says of the matter here...
1 CORINTHIANS 7 [19]
CIRCUMCISION IS NOTHING, AND UNCIRCUMCISION IS NOTHING, BUT THE KEEPING OF THE COMMANDMENTS OF GOD.
ACTS 15 is about “CIRCUMCISION” as a requirement for salvation and is not even considering Gods 10 Commandments. “Circumcision” is one of the shadow laws of the MOSAIC BOOK of the COVENANT.
Hope this is helpful.
