1Then after a period of fourteen years I went up again to Jerusalem with Barnabas, taking Titus also with me. 2I went up by revelation, and I laid before them the Good News which I preach among the Gentiles, but privately before those who were respected, for fear that I might be running, or had run, in vain. 3But not even Titus, who was with me, being a Greek, was compelled to be circumcised. 4This was because of the false brothers secretly brought in, who stole in to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage, 5to whom we gave no place in the way of subjection, not for an hour, that the truth of the Good News might continue with you. 6But from those who were reputed to be important—whatever they were, it makes no difference to me; God doesn’t show partiality to man—they, I say, who were respected imparted nothing to me, 7but to the contrary, when they saw that I had been entrusted with the Good News for the uncircumcised, even as Peter with the Good News for the circumcised— 8for he who worked through Peter in the apostleship with the circumcised also worked through me with the Gentiles— 9and when they perceived the grace that was given to me, James and Cephas and John, those who were reputed to be pillars, gave to Barnabas and me the right hand of fellowship, that we should go to the Gentiles, and they to the circumcision. 10They only asked us to remember the poor—which very thing I was also zealous to do.
11But when Peter came to Antioch, I resisted him to his face, because he stood condemned. 12For before some people came from James, he ate with the Gentiles. But when they came, he drew back and separated himself, fearing those who were of the circumcision. 13And the rest of the Jews joined him in his hypocrisy, so that even Barnabas was carried away with their hypocrisy. 14But when I saw that they didn’t walk uprightly according to the truth of the Good News, I said to Peter before them all, “If you, being a Jew, live as the Gentiles do, and not as the Jews do, why do you compel the Gentiles to live as the Jews do?
15“We, being Jews by nature and not Gentile sinners, 16yet knowing that a man is not justified by the works of the law but through faith in Jesus Christ, even we believed in Christ Jesus, that we might be justified by faith in Christ and not by the works of the law, because no flesh will be justified by the works of the law. 17But if while we sought to be justified in Christ, we ourselves also were found sinners, is Christ a servant of sin? Certainly not! 18For if I build up again those things which I destroyed, I prove myself a law-breaker. 19For I through the law died to the law, that I might live to God. 20I have been crucified with Christ, and it is no longer I who live, but Christ lives in me. That life which I now live in the flesh, I live by faith in the Son of God, who loved me and gave himself up for me. 21I don’t reject the grace of God. For if righteousness is through the law, then Christ died for nothing!”
There are several people mentioned in the New Testament named James. The name "Jacob" is a Latinized version of Yakob - or Jacob, a very common Jewish name. Here, the person in question is the brother of Jesus. In order to distinguish him from the other people named James in the NT, the early Church gave him the moniker "the Just." Although the Church later argued that James was the son of Joseph through a marriage previous to Mary or that "brother" actually means "cousin" (owing to the belief that Mary was a perpetual virgin), the Bible gives no indication that he was not the natural son of Joseph and Mary, and the actual brother of the Lord Jesus.
Almost nothing is known of James' early life. He grew up in Nazareth, and at first apparently did not believe (Mark 3:31-35; John 7:5). After the death and resurrection of Jesus, James became a leader of the church in Jerusalem. Paul reported to have met with James just after his conversion (Gal 1:18-20), and later Paul mentions James among the "pillars" of the church who "recognized the grace" of his call (Gal 2:9-10). James was also present at the Council of Jerusalem that decided Gentiles did not need to become Jews in order to follow Jesus (Acts 15:1-30). Finally, before Paul's arrest in Jerusalem, he met with James and "all the elders" (Acts 21:17-25). According to both Josephus and other early Church historians, James was martyred around A.D. 62 by being thrown from the "pinnacle of the Temple" and then stoned to death. He was said to have been buried and "his monument" was still present "by the temple" in the 4th century A.D.
In 2002 it was announced that an ossuary (bone box) had been found bearing the inscription, written in Aramaic, "James, son of Joseph, brother of Jesus." Although its authenticity has been challenged by some skeptics, experts have demonstrated that it is almost certainly authentic. Although the names "James (Yakob), "Joseph (Yoseph)," and "Jesus (Yeshua)" were very common in first century Judea, the specific combination written on the ossuary is unique, making the probability that it is indeed James' very high.
