Under the Old Covenant righteousness was according to the keeping of law.
Eze 18:4 Behold, all souls are mine; as the soul of the father, so also the soul of the son is mine: the soul that sinneth, it shall die.
Deu 6:25 And it shall be our righteousness, if we observe to do all these commandments before the LORD our God, as he hath commanded us.
Under the New Covenant forgiveness of sin is the good news. So righteousness is by confessing of faith in Christ's atonement for sins. The gospel has nothing to do with keeping the law. (false doctrines use schemes and Old Covenant texts to chain themselves to a judgement they cant win, by rejecting grace and truth for error.)
Rom 3:21¶But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets;
Rom 3:28Therefore we conclude that a man is justified by faith without the deeds of the law.
"(false doctrines use schemes and Old Covenant texts to chain themselves to a judgement they cant win, by rejecting grace and truth for error.)"
You yourself just used a text from Ezekiel 18, and even that you do not understand, which is clear by the fact that you cherry-picked from the passage what you wanted the scripture to say for you. The passage even uses the exact same proverb from Jeremiah which I quoted from in the previous post above.
Ezekiel 18:1-22 KJV
1 The word of the LORD came unto me again, saying,
2
What mean ye, that ye use this proverb concerning the land of Israel, saying, The fathers have eaten sour grapes, and the children's teeth are set on edge?
3
As I live, saith the Lord GOD, ye shall not have occasion any more to use this proverb in Israel.
4
Behold, all souls are mine; as the soul of the father, so also the soul of the son is mine: the soul that sinneth, it shall die.
5 But if a man be just, and do that which is lawful and right,
6 And hath not eaten upon the mountains, neither hath lifted up his eyes to the idols of the house of Israel, neither hath defiled his neighbour's wife, neither hath come near to a menstruous woman,
7 And hath not oppressed any, but hath restored to the debtor his pledge, hath spoiled none by violence, hath given his bread to the hungry, and hath covered the naked with a garment;
8 He that hath not given forth upon usury, neither hath taken any increase, that hath withdrawn his hand from iniquity, hath executed true judgment between man and man,
9 Hath walked in my statutes, and hath kept my judgments, to deal truly; he is just, he shall surely live, saith the Lord GOD.
10 If he beget a son that is a robber, a shedder of blood, and that doeth the like to any one of these things,
11 And that doeth not any of those duties, but even hath eaten upon the mountains, and defiled his neighbour's wife,
12 Hath oppressed the poor and needy, hath spoiled by violence, hath not restored the pledge, and hath lifted up his eyes to the idols, hath committed abomination,
13 Hath given forth upon usury, and hath taken increase: shall he then live? he shall not live: he hath done all these abominations; he shall surely die; his blood shall be upon him.
14 Now, lo, if he beget a son, that seeth all his father's sins which he hath done, and considereth, and doeth not such like,
15 That hath not eaten upon the mountains, neither hath lifted up his eyes to the idols of the house of Israel, hath not defiled his neighbour's wife,
16 Neither hath oppressed any, hath not withholden the pledge, neither hath spoiled by violence, but hath given his bread to the hungry, and hath covered the naked with a garment,
17 That hath taken off his hand from the poor, that hath not received usury nor increase, hath executed my judgments, hath walked in my statutes; he shall not die for the iniquity of his father, he shall surely live.
18 As for his father, because he cruelly oppressed, spoiled his brother by violence, and did that which is not good among his people, lo, even he shall die in his iniquity.
19
Yet say ye, Why? doth not the son bear the iniquity of the father? When the son hath done that which is lawful and right, and hath kept all my statutes, and hath done them, he shall surely live.
20
The soul that sinneth, it shall die. The son shall not bear the iniquity of the father, neither shall the father bear the iniquity of the son: the righteousness of the righteous shall be upon him, and the wickedness of the wicked shall be upon him.
21
But if the wicked will turn from all his sins that he hath committed, and keep all my statutes, and do that which is lawful and right, he shall surely live, he shall not die.
22
All his transgressions that he hath committed, they shall not be mentioned unto him: in his righteousness that he hath done he shall live.
This is what it means to actually believe on the Testimony of the Messiah in the Gospel accounts because he is continually expounding the Torah and the Prophets in all his teachings. If one says he or she believes, and does not do, they are not his, (Romans 8:9).
Ephesians 2:1-3 KJV
1 And you
hath he quickened,
who were dead in trespasses and sins;
2 Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:
3 Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.
Ezekiel 18:21 KJV
21 But if the wicked will turn from all his sins that he hath committed, and keep all my statutes, and do that which is lawful and right, he shall surely live, he shall not die.
The Ephesians actually believed on the Testimony of the Messiah and were actually doing his commandments and teachings: not just naming and claiming something to get a reward.
Luke 14:25-27 KJV
25 And there went great multitudes with him: and he turned, and said unto them,
26 If any man come to me, and hate not his father, and mother, and wife, and children, and brethren, and sisters,
yea,
and his own life [psuche - soul] also,
he cannot be my disciple.
27
And whosoever doth not bear his cross,
and come after me,
cannot be my disciple.
