I disagree
1) Christ Followed the Torah perfectly, but Christ actually showed his followers the goals of the Torah. You make it sound like the Torah was a goal in and of itself. The Torah has been described as a kind of "Gospel" in the Old Testament, and this fits in with the late Shadow terminology because it literally was. Getting saved by Moses with the plagues is most definitely a kind of Salvation from being slowly worked death in the hot sun of Egypt!. In that sense, the Torah was very reasonable. The Torah is however burdensome from a stand point of absolute perfection, where he even saint James said it was so in the book of Acts.
In Exodus 33:13, Moses wanted God to be gracious to him by teaching him to walk in His way that he and Israel might know Him, and 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 the goal of the Torah is to graciously teach us how to know God and Jesus, which is the narrow way to eternal life (John 17:3).
The Gospel that Jesus taught in Matthew 4:15-23 called for repentance from our disobedience to the Torah, so that is a central part of the Gospel, not a kind of "Gospel".
In Psalm 119:29-30, he wanted to put false ways far from him, for God to be gracious to him by teaching him to obey the Torah, and he chose the way of faith by setting it before him, so this has always been the one and only way of salvation by grace through faith. Jesus saves us from our sin (Matthew 1:21) and it is by the Torah that we have knowledge of what sin is (Romans 3:20), so Jesus graciously teaching us to be a doer of the Torah is intrinsically the way that he is giving us his gift of saving us from not being a doer of it. It is contradictory for someone to think that they need salvation from sin while also thinking that they have no obligation to obey the Torah.
In 1 John 5:3, to love God is to obey His commandments, which are not burdensome. James did not say that the Torah was burdensome.
2) The Torah is inferior to the Gospel because it did not give eternal life!
In Romans 10:5-8, Paul referred to Deuteronomy 30 as the word of faith that we proclaim in regard to the righteousness that is by faith proclaiming that the Torah is not too difficult for us to obey and that obedience to it brings life and a blessing while disobedience brings death and a curse, so choose life! In Deuteronomy 32:46-47, the Torah is our very life. In Leviticus 18:5, those who obey the Torah will attain life by it. In Proverbs 3:16-18, the Torah is a Tree of Life for all who take hold of it. In Revelation 22:14, those who kept God's commandments are given the right to eat from the Tree of Life. In Proverbs 6:23, for the commandment is a lamp and the teaching a light, and the reproofs of discipline are the way of life. In Matthew 19:17, Jesus said that the way to enter eternal life is by obeying God's commandments. In Luke 10:25-28, Jesus affirmed that the way to inherit the gift of eternal life is by obeying the greatest two commandments of the Torah. In Hebrews 5:9, Jesus has become a source of eternal salvation for those who obey him. In Romans 2:6-7, those who persist in doing good will be given eternal life. In Romans 6:19-23, we are no longer to present ourselves as slaves to impurity, lawlessness, and sin but are now to present ourselves as slaves to God and to righteousness leading to sanctification, and the goal of sanctification is eternal life in Christ, which is the gift of God, so the experience of getting to be a doer of the Torah is God's gift of eternal life.
Key Bible Verses (Easy Copy-Paste Format)
These drive home that the Torah/Law was not given to grant eternal life (theosis, divine life). Eternal life comes through the promise to Abraham, fulfilled in Christ (faith, not works of Torah). Fr. De Young often highlights these in Romans, Galatians, and Hebrews contexts.
Galatians 3:21 (core verse Fr. De Young cites directly):
God did give the Torah as a way to earn the promise or our righteousness as the result, but rather the only way to receive them is through faith, however, that does not mean that there is no connection between them. The promise was made to Abraham and brought about because he walked in God's way in obedience to His law, he taught his children and those of his household to do that, and because they did that in obedience to the Torah (Genesis 18:19, Genesis 26:4-5, Deuteronomy 30:16). The Torah is how the children of Abraham know how to be blessed by walking in God's way (Psalm 119:1-3), so the way that the children of Abraham are multiplies and are a blessing to the nations in according with inheriting the promise through faith is by turning the nations from their wickedness and by teaching them to obey the Torah in accordance with spreading the Gospel (Acts 3:25-26). It is contradictory for someone to want to have the blessing of Abraham while not wanting to follow the Torah's instructions for how to receive the blessing of Abraham.
While Paul denied in Romans 4:1-5 that we can earn our righteousness as the result of our works, he also affirmed in Romans 2:13 that only the doers of the Torah will be declared righteous, so there is a reason why our righteousness requires us to choose to be a doer of the Torah other than in order to earn it as the result, namely faith insofar as the faith by which was aware declared righteous apart from works also upholds the Torah (Romans 3:28-31).
Galatians 3:10-14, 16-18 (context on Torah vs. Abrahamic promise):
According to Deuteronomy 27-30, the way to be blessed is by relying on the Book of the Law while the way to be cursed is by not relying on it, so it would absurd to interpret Galatians 3:10 as Paul quoting from that passage in order to support a point that is arguing the opposite of that passage. Rather, the fact that everyone who does not continue to do everything in the Book of the Law comes under a curse straightforwardly means that we should continue to do everything in the Book of the Law and that everyone who rely on works of the law instead come under that curse. God did not give the Torah as a curse but as instructions for teaching us how to not be cursed, so Jesus free us from the curse of the Torah is freeing us to enjoy the blessing of getting to be a doer of the Torah.
Romans 3:20 (and surrounding; law reveals sin, doesn’t justify):
If you agree that the Torah gives us knowledge of what sin is and that we should refrain from doing what God has revealed to be sin, then you should be arguing in favor of obeying the Torah.
Romans 7:10 (the commandment was for life, but brought death because of sin):
In Romans 7:12-13, Paul said that the Torah is good and that it was not that which is good that brought death to him.
Hebrews 7:18-19 (law made nothing perfect; better hope in Christ):
The Torah is perfect (Psalm 19:7), so it was not given as a way of becoming prefect, but rather it was given to describe the behavior of those who have been made perfect.
Hebrews 8:7-8, 13 (first covenant faultless? No; becoming obsolete):
Hebrews 87-9 does not say that the fault that God found with the Mosaic Covenant was with the Torah but with the people for not continuing in their covenant, so the solution to the problem was not to do away with the Torah but to do away with what was hindering us from obeying it, which is why the New Covenant involves God putting the Torah in our minds and writing it on our heart (Hebrews 8:10), so the Mosaic Covenant becoming obsolete does not mean that we should no longer obey the Torah.
John 5:39-40 (Jesus to the Jews: “You search the Scriptures, for in them you think you have eternal life; and these are they which testify of Me. But you are not willing to come to Me that you may have life.”)
I've quoted many verses that show that eternal life can be found in the Scriptures, so the Pharisees were correct to sear for it there, but they needed to recognize that the goal of everything in Scripture is to teach us how to know Christ and to enter into a relationship with him for eternal life.
These show the Torah’s role was not earning eternal life—it managed sin, maintained holiness for God’s presence among Israel, and pointed forward to Christ. Eternal life was always the Abrahamic promise, inherited by faith in Christ.
In Luke 10:25-28, Jesus affirmed that the way to inherit eternal life is by obeying the greatest two commandments of the Torah, and something that we inherit is a gift, so he was speaking about what is intrinsically requires to experience the gift of eternal life, not about the way to be good enough to earn it as the result. The Torah was never given as a way of earning eternal life even as the result of having perfect obedience to it, but that does not mean that eternal life does not require us to be a doer of the Torah through faith in Christ.
