In Jeremiah 31:33, the New Covenant involves God putting His law in our minds and writing it on our hearts, and in Ezekiel 36:26-27, the New Covenant involves God taking away our hearts of stone, giving us hearts of flesh, and sending His Spirit to lead us to obey His law. In Psalms 119:29-30, he wanted to put false ways far from him, for God to be gracious to him by teaching him to obey His law, and he chose the way of faithfulness by setting God's law before him, so this has always been the one and only way of becoming justified by grace through faith alone. God is trustworthy, therefore His law is also trustworthy (Psalms 19:7), so the way to have faith in God is by having faith in what He has instructed while it is contradictory to have faith in God while not having faith in what He has instructed. In Habakkuk 2:4, it says that the righteous shall live by faith, and this was written by people under the Mosaic Covenant, so it is not a depart from it, but rather it is the way to live under it, which is in accordance with the context of the rest of the chapter. Furthermore, in Isaiah 51:7, the righteous are those on whose heart is God's law, so the righteous living by faith does not refer to a manner of living that is not in obedience to it.
Every other time that the Greek word "dogma" is used by the Bible outside of Ephesians 2:15 and Colossians 2:14 it refers to something other than God's law, so you need to give justification for why it should be interpreted as referring to God's law in those verses, especially in light of the fact that all of God's righteous laws are eternal (Psalms 119:160). In addition, in Matthew 5:17-19, Jesus specifically said that he came not to abolish the law and warned against relaxing the least part of it or teaching others to do the same. Likewise, in Romans 3:31, Paul confirmed the our faith does not abolish our need to obey God's law, but rather our faith upholds it.
Christ is God's word made flesh, so it is contradictory to focus on him instead of focusing on obeying God's word. In Matthew 4:15-23, Jesus began his ministry with the Gospel message to repent for the Kingdom of God is at hand, which was a light to the Gentiles, and God's law was how his audience knew what sin is (Romans 3:20), so repenting from our disobedience to it is a central part of the Gospel of Christ.
In Matthew 7:23, Jesus said that he would tell those who are workers of lawlessness to depart from him because he never knew them, so knowing Jesus is the goal of the law. In Romans 9:30-10:4, they had a zeal for God, but it was not based on knowing Him, so they failed to attain righteousness because they misunderstood the goal of the law by pursuing it as through righteousness were earned as the result of their works in order to establish their own instead of pursing it as through righteousness is by faith in Christ, for knowing Christ is the goal of the law for righteousness for everyone who has faith. In Romans 10:5-10, the faith references Deuteronomy 30:11-16 as the word of faith that we proclaim in regard to saying that God's law is not too difficult for us to obey, that the one who obeys it will attain life by it, in regard to what we are agreeing to obey by confessing that Jesus is Lord, and in regard to the way to believe that God rose him from the dead. So nothing in this passage has anything to do with Jesus ending God's law, but just the opposite.
While it is true that there is no condemnation for those who are in Christ (Romans 8:1), those who are in Christ are obligated to walk in the same way he walked (1 John 2:6), so verses that speak about those who are in Christ only speaking about those who are walking in obedience to God's law. Moreover, in Romans 8:4-7, those who walk in the Spirit are contrasted with those who have minds set on the flesh who are enemies of God who refuse to submit to God's law. In Ephesians 2:8-10, we are new creations in Christ to do good works, as while we do not earn our salvation as the result of our works lest anyone should boast, doing good works in obedience to God's law is nevertheless a central part of our salvation. Our salvation is from sin (Matthew 1:21) and sin the transgression of God's law (1 John 3:4), so while we do not earn our salvation as a wage as the result of having first obeyed it, living in obedience to it through faith in Jesus is nevertheless intrinsically part of the concept of him saving us from not living in obedience to it. The NT authors quoted or alluded to the OT thousands of times in order to support what they were saying, so it is absurd to think doing that it is a perversion of New Covenant theology.
