Romans 2 has nothing to do with the Sabbath. The only place the Sabbath might be mentioned in the entire epistle is in chapter 14. So please try not to inject your commentary into what’s actually stated in the scriptures. Paul hasn’t said a single word about the sabbath since he began this epistle.
Religious men have separated God's Sabbaths from His Laws, not God.
Ex. 16:
25 And Moses said, Eat that to day; for to day is a sabbath unto the LORD: to day ye shall not find it in the field.
26 Six days ye shall gather it; but on the seventh day, which is the sabbath, in it there shall be none.
27 And it came to pass, that there went out some of the people on the seventh day for to gather, and they found none.
28 And the LORD said unto Moses, How long refuse ye to keep my commandments and my laws?
"Romans 2 has nothing to do with the Sabbath".
You say this because you have been convinced by the "other" voice in the garden that the Christ lied to you about His Sabbath. That it isn't God's Law, nor a "Good work" that God before ordained that we should walk in them, and that it wasn't made for man. You also seem to reject the Biblical Truth that Jesus, before becoming a man, created these Holy Days, and declared to the world that they are "His Feasts". they came about from HIS Mouth, they are commands HE gave as the Word of God.
He warned us about this very thing.
Also, a reminder about Romans 3 that you omitted. And that is who is Paul talking about in this chapter.
Rom. 3:
1 What advantage then hath the Jew? or what profit is there of circumcision?
2 Much every way: chiefly, because that unto them were committed the oracles of God.
3 For what if some did not believe? shall their unbelief make the faith of God without effect?
4 God forbid: yea, let God be true, but every man a liar; as it is written, That thou mightest be justified in thy sayings, and mightest overcome when thou art judged.
Now that we have added the context that Paul is speaking about Jews who didn't believe the "Oracles of God", we can continue.
“
Now we know that whatever the Law says, it speaks to those who are under the Law,"
Paul is speaking to men who have transgressed God's Commandments and are spiritually dead.
so that every mouth may be closed and all the world may become accountable to God;
We are all in the same place, dead and in need of salvation.
because by the works of the Law no flesh will be justified in His sight; for through the Law comes the knowledge of sin.
God had "ADDED" sacrificial atonement/justification "works" required to cover transgressions until the "SEED" should come. Paul knew this because he taught from and believed all that was written in the Law and Prophets (See Acts 24) As he said "I was alive once, then the Law came and I died", why? Because through the Law comes the knowledge of sin whose wages is death.
But now apart from the Law the righteousness of God has been manifested,
But now, we see Jesus forgiving sins "Apart" from the "works" God gave Moses to provide for forgiveness. Jesus didn't sprinkle the blood of a goat or bull on the alter to forgive sins, HE gave HIS own Blood and did not perform the "Works of the Law" required by God through the Levitical Priesthood "Till the seed should come".
being witnessed by the Law and the Prophets, even the righteousness of God through faith in Jesus Christ for all those who believe;
As it is written. "Hab. 4:4 "The Just shall live by Faith". And again Duet. 32:
20 And he said, I will hide my face from them, I will see what their end shall be: for they are a very froward generation, children in whom is no faith. And again in Jer. 31 "For I will forgive their sins", not a Levite Priest as per the "Works of the Law".
for there is no distinction; for all have sinned and fall short of the glory of God, being justified (Forgiven our sins)
as a gift by His grace through the redemption which is in Christ Jesus; whom God displayed publicly as a propitiation in His blood through faith.
So we are forgiven, not by going to the Levite Priest with a sin offering, as the Jews were still requiring, but by the Blood of the Lamb of God which is shed for us while we were still in Egypt, which symbolizes sin.
This was to demonstrate His righteousness,
because in the forbearance of God He passed over the sins previously committed; for the demonstration, I say, of His righteousness at the present time, so that He would be just and the justifier
of the one who has faith in Jesus.
Jesus is the "Restorer of Paths to walk in", the Prophesied Messiah, the Unblemished Lamb of God. It is HIS Blood and HIS Grace that saves us, not some preacher in a temple made with wood and stone, as per the "Law of Works"..
"Where then is boasting? It is excluded. By what "kind of" law, (poor translation )?
Of works? No, but by a
law of faith."
There are two Laws. One eternal,
Gen. 26:
5 Because that Abraham obeyed my voice, and kept my charge, my commandments, my statutes, and my laws.
and one "ADDED" Till the SEED should come.
Lev. 4:
20 And he shall do with the bullock as he did with the bullock for a sin offering, so shall he do with this: and the priest shall make an atonement for them, and it shall be forgiven them.
Abraham had the Law of Faith, but not the Law of Works. He was justified "Apart from the Law" of Works.
"
For we maintain that a man is justified (Atoned, forgiven) by (The Law of) faith apart from works of the Law (of works)."
Abraham was justified by obedience to God as with "EVERY" example of faith in the entire Bible. Do men slip, do they make mistakes? Sure, but in Every example of Faith in the Bible there was "Faithfulness" to the "WAY" of the Lord. And in EVERY Example of unfaithfulness, is disbelief and disobedience.
Or is God the God of Jews only? Is He not the God of Gentiles also? Yes, of Gentiles also, since indeed God who will justify the circumcised by faith and the uncircumcised through faith is one.
This is exactly what Paul teaches throughout his letters.
Rom. 2:
9 Tribulation and anguish, upon every soul of man that doeth evil, of the Jew first, and also of the Gentile;
10 But glory, honour, and peace, to every man that worketh good, to the Jew first, and also to the Gentile:
11 For there is no respect of persons with God.
Do we then nullify the Law through faith? May it never be! On the contrary, we establish the Law.
As Paul does. Rom. 7:
24 O wretched man that I am! who shall deliver me from the body of this death?
25 I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin.
The Jews Paul is speaking about were still promoting the Levitical Priesthood "Works of the Law" for justification. A "LAW" of atonement Abraham didn't have. A "LAW" that was not "ADDED" until 430 years after Abraham.
Abraham was justified "Apart" from these "Works of the Law" of Justification given to Levi "Till the seed should come".
But God blessed Abraham because when God gave Abraham HIS Laws, Commandments and Statutes, Abraham obeyed the Commandments, Statutes and Laws of God. Had Abraham rejected them as did the Children of Israel, Abraham would have been overthrown in the wilderness as well. But Abraham didn't practice iniquity. Like Caleb and Joshua and Gideon, and Zacharias, and Simeon and Noah and David, they all followed the "Way of the Lord", they all "Denied themselves" and followed the Word of God which became Flesh.
So it is true that we are not Justified by the sacrificial, ceremonial "works of the Law" of atonement given to Levi "Till the SEED should come", that the Jews were still promoting in Romans.
But we are required to repent, turn to God, and do works worthy of repentance according to Paul. Both Jew and Gentile. This is what Paul teaches. If you have been convinced that rejecting God's Laws or Sabbaths are "works worthy of repentance" then you are partaking of a Path followed by a great "Many", including the Israelite's who fell in the wilderness as examples to us.
Now is Paul teaching that justification is the result of obedience to the law?
You are following a cleaver deception that has snared a great many people, as prophesied by the Christ Himself.
Paul says "
13(For not the hearers of the law are just before God, but the doers of the law shall be justified.
Not "doers" of the "Works of the law" of the Levitical Priesthood given "Till the Seed should come". But the Law of Faith, "Thou shall Love the Lord your God with all your heart, and though shall Love thy neighbor as thyself" on which every Commandment, Statute and Law of God rests.
