If anyone is competent to issue an opinion about Christians keeping Jewish Law, it is Paul.
He wrote 14 books of our New Testament. He was a privately tutored pupil of Gamaliel, the leading Jewish teacher of the first century.
And he converted from being an ardent Jewish law-keeper to being an ardent Christian preacher.
Here is what God inspired Paul to say about keeping the Law.
"For if there was no need of circumcision before Abraham or of the observance of Sabbaths, of feasts and sacrifices, before Moses; no more need is there of them now,
“The Law is such a schoolmaster. Not for always but until we have been brought to Christ. The Law is not just another schoolmaster. The Law is a specialist to bring us to Christ...
“But lest it should be said, If the law was of this use and service under the Jewish, why may it not continue to be so under the Christian state too,
Baker's Evangelical Dictionary
“Law [Torah], as a method of the divine dealing with man, characterized the dispensation extending from the giving of the law to the death of Jesus Christ, Galatians 3:13,14,23,24.
C.I. Scofield, The Scofield Reference Bible. Torah
"We are no longer under a schoolmaster." The bondage and servitude [of the law] have passed away; and we are free from the burdensome ceremonies and expensive rites of the Jewish law, and from the sense of condemnation which it imposes.
This was true of the converts from Judaism to Christianity - that they became free from the burdensome rites of the law [Torah];
and it is true of all converts to the faith of Christ, that having been made to see their sin by the law, and having been conducted by it to the cross of the Redeemer, they are now made free.” [from the law]
Albert Barnes, Barnes’ Notes On The New Testament.
"Now here comes Jesus, and he undoes much of the Old Testament law. In fact, I think he undoes all of it as law, according to Romans 7:4 where it says that we died to the law so that we may belong to another. And the reason he undoes it is not because it was wrong under those circumstances to do what he said to do. Rather, with the coming of Christ, his rejection of an earthly kingdom, and the establishment of a spiritual kingdom, Jesus says that the kingdom will be taken away from the Jews and be given to a people who bear its fruits, that is, the church."
"The second purpose of the Law [Torah] was to provide a temporary provision for man’s sin until the permanent cure came in the person of Christ.
The purpose which God gave the Law was provisional and preliminary. Paul writes that the Law was given “until the seed to whom the promise referred had come” (v. 19).
The word “until” implies that the Law was not permanent, but provisional.
The Law was given as a temporary provision until that which was permanent came. The Law was like scaffolding which is used only during the period of construction and then is removed:
The Law was like the temporary walkways and walls in a building being remodeled...
The Book of Hebrews describes at length the superiority of Christ to the provisions of the Law (Torah), proving both the inferiority and the interim nature of the Law.
The Law of Moses is just like the... spare tire [in your trunk]. It was never intended to replace the promises of God made to all men through Abraham. It was temporary until the promises were fulfilled in Christ.
Once Christ had come, the Law was no longer required. To return to the Law, now superseded by the grace of God in Christ, is as foolish as going to a tire dealer and asking him to replace your tires with GM spares on each wheel.
Therefore, the observance of the Law, as previously required of Old Testament saints, is now only an anachronism, no longer binding on the New Testament believer.
Strongly implied in these verses is the foolishness of trying to “turn back the clock” to once again live under the restrictions of the Law.”

“Paul’s point is that the law (Torah) was intended to function only during this 1500 year period of anticipation... [approximately 1450 BC to AD 30]
The reign of law has ended for those believers who now through the coming of Jesus have become mature sons of God.”
Dr. James Montgomery Boice, Expositor’s Bible Commentary, Galatians, pp. 466, 468.
“It was a tragic hour when the Reformation churches wrote the Ten Commandments into their creeds and catechisms and sought to bring Gentile believers into bondage to Jewish law (Torah), which was never intended either for the Gentile nations or for the church."
Dr. Barnhouse was a prominent Presbyterian leader of American evangelicalism in the last half of the twentieth century.
"If ye be led by the Spirit, ye are not under the law" Galatians 5:18.
“It is plain that if to be under the law were the means of Christian holiness, it would have said, "ye are under the law," rather than "ye are not under the law."
But men are blinded. How could persons be more under the law than when they adopt the language of the Ten Commandments as the expression of their own relationship before God?
The moment you put Christians under the law [Torah] as that by which they have to walk, you are doing the very evil that the Epistle to the Galatians was intended to correct.”
William Kelly, (1821-1906), Irish evangelical Bible scholar. Kelly graduated in classical honors from Trinity College, Dublin and was a recognized scholar of formidable intellect.
He assisted Dr. Samuel P. Tregelles as a Biblical textual critic and Kelly himself published, in 1860, a critical edition of the Revelation of John.
It is clear from these quotes that the viewpoint that Christians are NOT under the law, that Torah observance is NOT required, is consistently the view of evangelicals for 2000 years, from the time of the Apostle Paul to the present time.
