Was Paul a devout Torah observant Jew?

 Re: some Christians who claim that the Apostle Paul appealed to the Law of Moses, therefore, Paul remained a Torah-observant Jew.

Now, it's of course true that "all scripture is God breathed and for our instruction," which includes the Old Covenant (OC) Law or Torah of Moses, the prophets, and the writings.

So I agree with Paul when he says in Romans 7.12:

"The Law is holy, and its commands are holy and right and good."

But the question is whether or not Paul continued observing that OC Torah in toto once he converted to Christianity, i.e., once he became "subject to the Law of Messiah" and was no longer "under the Law of Moses," as he confesses in 1Cor 9.20-21!

You will notice that some do not effectively deal with Paul's own words in 1Cor 9:19-21 or 2 Corinthians 3. Here, Paul goes on to describe the 10 commandments ("engraved in letters on stone") as "the ministry of death," and "condemnation"!

For Paul the Law of Moses as a whole now stands as a "fleeting glory," meaning it "was glorious." 2Cor 3:10-11

Also, in Galatians 3 Paul calls the Law of Moses “a tutor and guardian to lead us to the Messiah, so that we could then be made right by faith. And now that this faith has come, we are no longer under a guardian.”

In other words, we do not receive the spirit by obeying the Law of Moses but by the teaching/message of Jesus.

So for Paul the Law of Moses has no connection whatsoever with the faith/spirit that comes by Jesus not Moses.

This echoes 2 Corinthians 3 where the ministry of the Spirit, “written in our hearts,” has surpassed “the engraved in letters on stone, the ministry of death.”

Lastly, throughout his letters Paul teaches that both Jews and Gentiles are now one body, sharing in the one and the same spirit, the one and the same Jewish-Christian hope (1Cor 10.15-17; 12:13; Eph. 2.11-18; 4.4-5; Col 3.10-11).

But I’m afraid that some Christians have once again erected that dividing wall of hostility, i.e., “the law with its commands and regulations,” between Jew and Gentile. And in the process effectively split the one body of Christ, united by the one spirit, in the one hope for the whole Jewish-Christian church!

Hence, Paul’s question in Rom 3.29a:

“Is God the God of Jews only? Is He not the God of Gentiles too?”
