I think it's more just conflating too many doctrines together in my opinion. Really it's just think way simpler, like the Law was never meant to save, but to discern, it's not like sins aren't sins anymore just because of the old covenants being fulfilled in the person of Jesus Christ and his new covenant established (which is a continuation of promises made even all the way back from the first mortal day in the Garden). It's similar to like the covenants made with Moses didn't become obsolete or reprsent a different dispensation just because the covenants with David were made. We view the whole scripture as a comprehensive whole, the covenants, Law, prophecies, teachings, histories, etc. supporting eachother until the end of reality itself.
1 Timothy 1:8-10
Gal 6:2 - Bear ye one another's burdens, and so fulfil the law of Christ.
Dr. Arnold Fruchtenbaum’s exegesis of the "Law of Christ" (Torat HaMashiach) in Galatians 6:2 is tied directly to his dispensational framework and his theology of Biblical covenants.
To understand how he unpacks this passage without falling into antinomianism (lawlessness) while firmly holding that the Mosaic Law is obsolete, his teaching breaks down into a few core principles:
1. The Concept of "Law Codes"
Fruchtenbaum emphasizes that God has governed different eras of human history with distinct, comprehensive legal codes. The termination of one code does not mean believers are lawless; rather, it means they have been placed under a completely new administration.
The Mosaic Law was a single, indivisible unit consisting of all 613 mitzvot (commandments). It was given strictly to Israel, and its authority was terminated in its entirety at the Cross (Romans\ 10:4, Hebrews\ 8:13).
The Law of Christ (also called "the Law of the Spirit of life in Christ" in Romans\ 8:2) is the new, distinct code governing the New Testament believer today.
2. The Overlap, Not Continuation
A common point of confusion is why some commandments in the New Testament look identical to those in the Old Testament (e.g., prohibitions against murder, theft, or the call to love one's neighbor).
Fruchtenbaum explains this using an architectural or legislative analogy: when a government writes a completely new constitution, it may adopt specific laws from the old system. However, those laws do not carry authority because they were in the old system; they carry authority because they have been formally restated in the new one.
Fruchtenbaum's Rule: If a Mosaic commandment is not explicitly restated under the Law of Christ, it is completely abrogated. If it is restated, it is binding on the believer solely because it is part of the Law of Christ.
For instance, nine of the Ten Commandments are restated in the New Testament epistles and are thus part of the Law of Christ. The Sabbath commandment is never restated for the Church and is therefore not binding.
3. Exegesis of Galatians 6:2 and "Bearing Burdens"
In the immediate context of Galatians 6:2, Paul is wrapping up a letter fiercely defending liberty from the Mosaic Law against Judaizers. Right after telling them they are free from the law of Moses, he tells them to fulfill the "Law of Christ" by bearing one another's burdens.
Fruchtenbaum notes that the supreme, motivating ethos of this new code is sacrificial love energized by the Holy Spirit. While the Mosaic Law provided an external yoke of performance, the Law of Christ operates via an internal transformation (Romans\ 7:4, 6). Bearing a brother or sister's burden in restoration and community is the ultimate practical expression of the love Christ commanded (John\ 13:34).
