Hebrews 8:13 stands unequivocally and irrefutably against so-called 'Torah Observant' "Christians"—that is, modern-day Judaizers.
"In speaking of a new covenant, He makes the first one obsolete. And what is becoming obsolete and growing old is ready to disappear."
According to Deuteronomy 4:2 and 12:32, no commandments shall be added to or taken away from the Law of Moses. Huh... Well, is that not a precarious predicament. Jesus gave us new commandments not found in the Law (Matt 28:18-20; Mark 16:15; John 13:34). Seems the "Torah Observant" cult have a problem on their hands. Are they going to attempt to say that Jesus sinned and/or is not the Messiah?
Torah observance undermines both the Gospel of Jesus and the sufficiency of His work in making us right with Yahweh. It also undermines the accomplishments of Jesus through His life, death, and resurrection.
If you are going to attempt to observe the Torah, then that would have to include circumcision. However, what does Paul say? "If you accept circumcision, Christ will be of no advantage to you" (Gal. 5:2). He continues, "Neither circumcision nor uncircumcision counts for anything, but only faith working through love" (Gal. 5:6).
If you are going to attempt to observe the Torah, then that would also have to include the eating of kosher foods (Lev. 11:44-45). However, Jesus and the apostles taught us that all foods are clean (Mark 7:1-23; Acts 10:9-16; Rom 11:11-24; 14:1-15:13).
From AD 70 until today, it has been impossible for anyone to live a truly "Torah Observant" lifestyle. According to traditional Judaism, there are 613 commandments. However, after the destruction of Jerusalem and the temple, only 369 of the 613 commandments are able to be observed. As I have said before, if you want to attempt to live by the Law, you are required to live by all of it—all 613 commandments!!! There is no cherry picking! If you fail in even one point of the Law, you are guilty of breaking all of it!!!
The Law was given to Moses as a ministry of condemnation and death (2 Cor. 3:7-11). It was given to Israel only (Ex. 19:3). Gentiles were never under the Law and never had a part in the Law (Eph. 2:11-12), including the Sabbath requirements. No other nation or people group was part of the Mosaic covenant.
The New Covenant Scriptures reveal that under Jesus and the New Covenant, everything changed! The New Covenant is radically different from the previous Covenant. Under the former covenant, the people of God were designated through ethnicity and lineage. Under the new covenant, "There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female, for you are all one in Christ Jesus. And if you are Christ's then you are Abraham's offspring, heirs according to the promise" (Gal. 3:28-29). Believers in Jesus are considered Abraham's offspring.
How many times does it have to be said for the so-called 'Torah Observant' cult member to grasp the truth? The Jewish era, the Old Covenant, the Law, has been made obsolete. It is null and void. It has been abolished. Jesus fulfilled the Law perfectly. Moses and the Prophets were shadows of the real thing, which is found in Christ Jesus. These modern-day Judaizers are spitting directly in the face of Jesus while rejecting the work He came to accomplish on our behalf and in our stead. These scripturally illiterate and ignorant clowns should answer Paul's rhetorical question to the Galatians: "Having begun by the Spirit, are you now being perfected by the flesh?"
