The only "change" according to the Words of God who created the promise of the New covenant in the first place, is the manner in which God's Laws are received, and the manner in which transgression of God's Laws are forgiven. You can read it for yourself. There is nothing in the entire Law and Prophets where God's Laws are prophesied to be abolished at the appearance of the Messiah. NOT ONE WORD. Only the Priesthood "works of the Law" for remission of sins were to change.
This needs some clarification and your post is too long to respond as well as your choice of isolated verses, here and there-here a little, there a little--
The New Covenant and the Law: The New Covenant does not abolish God’s moral law but transforms how it is received and applied. As Jeremiah 31:31-34 (quoted in Hebrews 8:6-13) states, under the New Covenant, God's laws are written on the hearts of believers rather than externally on tablets of stone. This means that obedience to God is now an internal transformation through the Spirit rather than mere external adherence to regulations (cf. Ezekiel 36:26-27).
The Change in Remission of Sins- The Levitical priesthood and sacrificial system were shadows pointing to Christ (Colossians 2:16-17; Hebrews 10:1-4). The "works of the Law" (ἔργα νόμου, erga nomou)—meaning the ceremonial sacrifices, rituals, and temple ordinances-were indeed changed
because Christ's once-for-all sacrifice fulfilled their purpose (Hebrews 9:12-14, 10:10-14).
However, the moral principles of God's law are still upheld but fulfilled in Christ (Matthew 5:17-18; Romans 8:3-4).
Was the Law Abolished?
No, but its role in justification was set aside. Paul explicitly states that believers are not under the law but under grace (Romans 6:14; Galatians 3:24-25). The law was not abolished but fulfilled in Christ, meaning its righteous demands are met in believers through faith (Romans 3:31; 8:4).
As to the Priesthood -your statement correctly notes that the Levitical priesthood was replaced with the priesthood of Christ after the order of Melchizedek (Hebrews 7:11-12, 24-25). Since Christ is now the eternal High Priest, the Old Covenant
sacrificial system is obsolete (Hebrews 8:13; 10:9).
Heb 8:10 For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people:
Heb 8:11 And they shall not teach every man his neighbour, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest.
Heb 8:12 For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more.
Heb 8:13 In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away.
In that he saith (en tōi legein). Locative case of the articular present active infinitive of legō, “in the saying as to him.”
He hath made the first old (pepalaiōken tēn prōtēn). Perfect active indicative of palaioō, old verb from palaios (in contrast with kainos, fresh, new), to treat as old and out of date. The conclusion is to the point.
That which is becoming old and waxeth aged (to palaioumenon kai gēraskon). Gēraskō is old verb from gēras (age) like gerōn (old man) and refers to the decay of old age so that both ideas appear here in opposition to kainos (palaios) and neos (geraios).
Is nigh unto vanishing away (eggus aphanismou). Genitive case with eggus and late word for disappearance (from aphanizō, Mat_6:19), here only in the N.T. The author writes as if the Old Testament
legal and ceremonial system were about to vanish before the new covenant of grace. If he wrote after A.D. 70, would he not have written “has vanished away”?
Heb 10:7 Then said I, Lo, I come (in the volume of the book it is written of me,) to do thy will, O God.
Heb 10:8 Above when he said, Sacrifice and offering and burnt offerings and offering for sin thou wouldest not, neither hadst pleasure therein; which are offered by the law;
Heb 10:9 Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second.
Heb 10:10 By the which will we are sanctified through the offering of the body of Jesus Christ once for all.
Heb 10:11 And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins:
Heb 10:12 But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God;
Heb 10:13 From henceforth expecting till his enemies be made his footstool.
Heb 10:14 For by one offering he hath perfected for ever them that are sanctified.
Heb 10:15 Whereof the Holy Ghost also is a witness to us: for after that he had said before,
Heb 10:16 This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them;
Heb 10:17 And their sins and iniquities will I remember no more.
Heb 10:18 Now where remission of these is, there is no more offering for sin.
The moral law (righteousness, holiness) is still relevant but is now written on the heart through the Holy Spirit (Romans 8:4).
The ceremonial law (sacrifices, temple rituals) was fulfilled and no longer applies under the New Covenant (Colossians 2:14-17).
The priesthood was changed because Christ’s perfect sacrifice ended the need for Levitical mediation (Hebrews 7:23-27).
Salvation is not through the Law but by faith in Christ alone (Ephesians 2:8-9; Galatians 2:16).
Thus, while the law was not abolished, it was fulfilled and transformed in Christ, meaning believers live by the Spirit, not by external legal observance (Galatians 5:18; Romans 7:6).
The Old Testament (Law) Was Given for Our Learning (Romans 15:4)
Romans 15:4 affirms that the Old Testament Scriptures were written for instruction, encouragement, and hope
. However, Paul does not say that believers are still under the Law of Moses for justification, but that the Scriptures provide wisdom and teaching (cf. 1 Corinthians 10:11).
2. The Law Was Changed (Hebrews 7:12; 8:7-8, 13; 10:9; Ephesians 2:13-15; Colossians 2:14)
Hebrews 7:12 states that "the priesthood being changed, there is made of necessity a change also of the law." This does not mean that God's moral righteousness changed,
but rather that the Levitical system (sacrifices, priesthood, temple rituals) was replaced by Christ’s eternal priesthood after the order of Melchizedek (Hebrews 7:11-28).
Ephesians 2:13-15 speaks of Christ abolishing the "law of commandments contained in ordinances," referring to the ceremonial law, not God's moral standards.
Colossians 2:14 describes how Christ canceled the "handwriting of ordinances" (δόγμασιν, dogmasin), which refers to the legal requirements of the Mosaic Covenant that were set aside in Christ.
3. The Law Ended at the Death of Christ (Hebrews 9:15-17; Galatians 3:19, 16, 24-25; Galatians 5:4, 18)
The Mosaic Covenant ceased to be binding with Christ’s death (Hebrews 9:15-17), but this does not mean all aspects of God’s law were abolished.
Galatians 3:19-25 explains that the Law was a temporary "guardian" (παιδαγωγός, paidagōgos) to lead people to Christ, but after faith has come, we are no longer under a tutor (v. 25).
Galatians 5:4, 18-If one seeks justification by the Law, they are "severed from Christ." However, this does not mean moral principles like holiness and righteousness (which reflect God's character) are irrelevant.
4.
The Sabbath Was Given to the Jews (Deuteronomy 5:2-3, 15)
Deuteronomy 5:2-3 makes clear that the Mosaic Covenant (including the Sabbath) was given specifically to Israel at Sinai, not to the patriarchs.
Nehemiah 9:13-14 confirms that the Sabbath command was made known at Sinai, meaning it was not universally binding before that.
The Old Testament Law provides wisdom but is not the basis for Christian justification (Romans 15:4; Galatians 3:24-25).
The Levitical system and ceremonial ordinances were fulfilled and replaced by Christ's priesthood (Hebrews 7:12; Colossians 2:14).
The Sabbath was uniquely given to Israel and was part of the Mosaic Covenant (Deuteronomy 5:2-3).
I know you are going to balk at the Sabbath-
The moral law of God was not abolished (Matthew 5:17-18; Romans 8:4), though Christians are not under the Law of Moses for salvation (Galatians 3:25).
The Law ended in terms of authority over believers for justification (Romans 6:14), but God’s righteous standards remain (Romans 8:3-4).
Thus, while Christ fulfilled the Law, and believers are under grace, the principles of holiness, righteousness, and obedience still matter,
but they are now lived out through the Spirit, not by the letter of the Law (Romans 7:6; Galatians 5:16-18).
And I don't hold to sinless perfection
@Studyman since
perfect means "mature" IN Christ Jesus.
Thanks.
