“For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek. For in it the righteousness of God is revealed from faith to faith; as it is written: “But the righteous one will live by faith.””
Romans 1:16-17 NASB2020
For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek. For in it the righteousness of God is revealed from faith

16 For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.
17 For therein is the righteousness of God revealed from faith to faith: as it is written, (In the Gospel of Christ) The just shall live by faith. (Hab. 2:4)
18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness; 19 Because that which may be known of God is manifest in them; "for God hath shewed it unto them".
Heb. 4:
1 Let us therefore fear, lest, a promise being left us of entering into his rest, any of you should seem to come short of it. 2 For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard it.
Deut. 32:
18 Of the Rock that begat thee "thou art unmindful", and hast forgotten God that formed thee. 19 And when the LORD saw it, he abhorred them, because of the provoking of his sons, and of his daughters. 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.
1 Cor. 10:
1 Moreover, brethren, I would not that ye should be ignorant, how that all our fathers were under the cloud, and all passed through the sea; 2 And were all baptized unto Moses in the cloud and in the sea; 3 And did all eat "the same spiritual meat"; 4 And did all drink "the same spiritual drink": for they drank of that spiritual Rock that followed them: and that Rock was Christ.
Col. 1:
23 If ye continue in the faith grounded and settled, and be not moved away "from the hope of the gospel", which ye have heard, and which was preached "to every creature which is under heaven"; whereof I Paul "am made a minister;"
According to Paul, the Gospel he was set apart for, was preached before him, "to every creature under heaven".
The gospel here refers to:
“Paul, a bond-servant of Christ Jesus, called as an apostle, set apart for the gospel of God, which He promised beforehand through His prophets in the holy Scriptures, concerning His Son, who was born of a descendant of David according to the flesh, who was declared the Son of God with power according to the Spirit of holiness by the resurrection from the dead, Jesus Christ our Lord, through whom we have received grace and apostleship to bring about the obedience of faith among all the Gentiles in behalf of His name, among whom you also are the called of Jesus Christ;”
Romans 1:1-6 NASB2020
Paul, a bond-servant of Christ Jesus, called as an apostle, set apart for the gospel of God, which He promised beforehand through His prophets in the holy Scriptures, concerning His Son, who was born

The prophets here refers to those that prophesied the coming of Christ.
That's not what Paul is teaching. Please try and separate yourself from your adopted religious philosophy for just a minute, and read what Paul actually said about the "Gospel of Christ".
16 For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek. 17 For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith.
This doesn't mean to just believe Jesus came. Demons believe Jesus came. Those Christians Jesus didn't know in Matt. 7, believed Jesus came.
That isn't the Gospel of Christ.
The implication of your religious philosophy here, that the Gospel of Christ didn't exist before Paul or Constantine, is a popular religious philosophy promoted by "Many" who call Jesus Lord, Lord. And of a truth, many of this world's religions who come in Christ's Name, promote a gospel that didn't exist until Constantine. But the Biblical truth is clear, the Gospel Paul promoted, had been shown to the Jew and the non-Jew since before Moses.
The early church did not persecute the Jews.
God's Church was always filled with men who were Jews inwardly, as Paul taught both Jew and Gentile. Remember, Jesus said "Salvation is of the Jews". A Jew here is defined as "Children of Abraham".
The Jews were cut off the tree and the time of the gentiles ushered in.
Only disobedient Jews were cut off of the Holy Tree. Those biological Jews who who did not do the "works of Abraham", at least this is what the Holy Scriptures teach. Any Gentile who joined themselves to the Lord were part of God's Church from the very beginning.
Lev. 19:
33 And if a stranger (Non-Jew/Israelite) sojourn with thee in your land, ye shall not vex him. 34 But the stranger (Non-Jew/Israelite) that dwelleth with you shall be unto you as one born among you, and "thou shalt love him" as thyself; for ye were strangers in the land of Egypt: I am the LORD your God.
Please read Heb. 11, and find a list of just a few men who were "Jews inwardly". These men were given the gospel of Christ, and mixed their hearing with belief, AKA "Faith".
The title of church of God refers to the Christian church.
A "church" who calls Jesus Lord, Lord, builds great massive religious businesses, and man-made shrines of worship in Christ's name, even casts out demons in Christ's Name, but lives in transgression of God's Commandments is not God's Church. You can find this understanding in the Holy scriptures, including the Words of Jesus Himself.
We are in agreement here. Even after the Bible was fully compiled the OT remains as inspired scripture. However, the scriptures are also clear that a new covenant was ushered in that replaced the old covenant so the Old Testament remains as the Old covenant no longer in force.
According to God's Definition of His His Own New Covenant, which I believe a man should consider if they want to know the Truth of God, there were only 2 things that were prophesied to change.
#1. The manner in which God's Laws were administered. No more is a person required to go find a Levite Priest to learn about God's Laws. God will write them on the hearts of those who, as Paul taught both Jew and gentile, "Repented, turned to God and were doing "works" worthy of repentance. And here we are today, with the Oracles of God in our own Homes, in our own mind. All men need is the same thing they always needed, "Belief".
#2. The manner in which Forgiveness is provided for. No longer is a man required to go find a Levite Priest and engage in the sacrificial "works of the Law" for remission of sins. God Himself provides for the atonement. Even Abraham understood this.
Gen. 22:
7 And Isaac spake unto Abraham his father, and said, My father: and he said, Here am I, my son. And he said, Behold the fire and the wood: but where is the lamb for a burnt offering? 8 And Abraham said, My son, God will provide himself a lamb for a burnt offering: so they went both of them together.
The teaching of this world's religious system, that God's Laws were against men so God abolished His own Laws, is a poplar religious philosophy of this world. But as any man can see, if they reads God's own description of his Own New Covenant, it was the Priesthood Covenant HE made with Levi on Israel's behalf, that was changed into a Priesthood "After the Order of Melchizedek", a incorruptible Priesthood. As God points out in His Inspired Word.
Mal. 2:
7 For the priest's lips should keep knowledge, and they should seek the law at his mouth: for he is the messenger of the LORD of hosts.
8 But ye are departed out of the way; ye have caused many to stumble at the law; ye have corrupted the covenant of Levi, saith the LORD of hosts. 9 Therefore have I also made you contemptible and base before all the people, according as ye have not kept my ways, but have been partial in the law.
Heb. 8 confirms this.
6 But now hath he obtained a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises.
7 For if that first covenant had been faultless, then should no place have been sought for the second.
8 For finding fault with them, (Corruptible Priests) he saith, Behold, the days come, saith the Lord, when I will make a new covenant with the house of Israel and with the house of Judah:
“For if that first covenant had been free of fault, no circumstances would have been sought for a second. When He said, “A new covenant,” He has made the first obsolete. But whatever is becoming obsolete and growing old is about to disappear.”
Hebrews 8:7, 13 NASB2020
For if that first covenant had been free of fault, no circumstances would have been sought for a second. For in finding fault with the people, He says, “BEHOLD, DAYS ARE COMING, SAYS THE LORD, WHEN I

So although the Old Testament is still scripture the covenant itself no longer applies to those who the new covenant applies. The Christian is not under the Jewish laws.
This is in part true. The "Jews Religion" that Paul was a part of when they murdered Stephen, "Full well rejected the Commandments of God so they could promote their own religious traditions. Jesus said they taught for doctrines the Commandments of men, not God. They were given God's Laws through Moses, and even told of the Prophesied Priest that was to come, but they didn't believe Moses. They, not God, placed grievous burdens on the necks of men. Their Law, not God's Law, condemned Jesus Stephen and the Prophets before them to death. So it is true that those who had "Yielded themselves" servants to obey God, and serve the Law of God with their minds, as Paul taught, and Lived by every Word of God, as Jesus taught, no longer participated or lived under "Jewish Law".
Instead they repented of following this world's religious system that has always, and will always be at enmity with God, and turned to God's Judgments, Commandments and Statutes, which are not "Jewish Laws", rather, they are the Laws many Jews rejected and were cut off because of it.
My friend, take a leap of Faith and become a "Doer" of the Jesus "of the Bibles" sayings, not a hearer only, and become renewed in your mind, that you might put on "
the new man, which after God is created in righteousness and true holiness. Like Jesus was.
