Gospel of Thomas Saying (12) The disciples said to Jesus, "We are aware that you will depart from us. Who will be our leader?" Jesus said to him, "No matter where you come it is to James the Just that you shall go, for whose sake heaven and earth have come to exist."
The Gospel of Thomas tells us that after Jesus had departed from the disciples they were to go to James the Just as the new leader of the apostles
So who is James the Just or James the righteous?
James Greek equivalent of Jacob, meaning “One Seizing the Heel; Supplanter
It also appears that the Lord’s brethren, James and Jude were married. Paul speaks of the married brothers of Jesus and the oldest gospel, Mark, mentions James, Joses, Judas and Simon as his brothers and besides sisters (Mark vi. 3).
It appears that during Jesus’ ministry James was well acquainted with his brother’s activity (Lu 8:19; John 2:12), but he was not one of the disciples and followers of Christ. (Mt 12:46-50; John 7:5)
He was probably with his non-believing brothers when they urged Jesus to go up to the Festival of Tabernacles, at a time when the rulers of the Jews were seeking to kill him. (John 7:1-10)
James also may have been numbered among the relatives that said of Jesus: “He has gone out of his mind.”—Mr 3:21.
However, after the death of Jesus James was assembled for prayer together with his mother, brothers, and the apostles in an upper chamber in Jerusalem. (Ac 1:13, 14)
It was evidently to this James that the resurrected Jesus appeared personally, as reported at 1 Corinthians 15:7, so convincing this one time non-believer that He was indeed the Messiah. This reminds us of Jesus’ personal appearance to Paul.—Ac 9:3-5.
The Gospel of the Hebrews confirms the account of Paul in 1 Corinthians regarding the risen Jesus' appearance to James:
'Now the Lord, after he had given his grave clothes to the servant of the priest, appeared to James, for James had sworn that he would not eat bread from that hour in which he had drunk the Lord's cup until he should see him risen from the dead.' And a little further on the Lord says, 'bring a table and bread.' And immediately it is added, 'He took bread and blessed and broke and gave it to James the Just and said to him, "My brother, eat your bread, for the Son of Man is risen from the dead."' And so he ruled the church of Jerusalem thirty years, that is, until the seventh year of Nero
Thus, at Paul’s first visit with the brothers in Jerusalem (about 36 C.E.), he says he spent 15 days with Peter but “saw no one else of the apostles, only James the brother of the Lord.” (Ga 1:18, 19)
Although not one of the 12 apostles, it is evidently this James who was a bishop of the Christian Church at Jerusalem (Ac 12:17)
Peter, after his miraculous release from prison, instructed the brothers at John Mark’s home, “Report these things to James and the brothers,” thereby indicating James’ superiority. (Ac 12:12, 17)
James is styled the "bishop of bishops, who rules Jerusalem, the Holy Church of the Hebrews, and all the Churches everywhere"
Clement to James, the lord, and the bishop of bishops, who rules Jerusalem, the holy church of the Hebrews, and the churches everywhere excellently rounded by the providence of God, with the elders and deacons, and the rest of the brethren, peace be always. (Epistle of Clement to James)
Fragment X of Papias (writing in the second century) refers to "James the bishop and apostle" (Papias of Hierapolis,. Exposition of the Sayings of the Lord. Fragment X).
According to Eusebius (3rd/4th century) James was named a bishop of Jerusalem by the apostles: "James, the brother of the Lord, to whom the episcopal seat at Jerusalem had been entrusted by the apostles".[40] Jerome wrote the same: "James... after our Lord's passion... ordained by the apostles bishop of Jerusalem..." and that James "ruled the church of Jerusalem thirty years".[41]
What about the great church meeting in Acts 15?
About 49 C.E. the issue of circumcision came before “the apostles and the elders” at Jerusalem.
Did Peter stand out as the leader in this great meeting? No, Peter did speak, but if you read the whole of that meeting, you will see that in fact James seemed to be the chief of the elders, as he was the one who gave the final decision on the question of circumcision (see Acts 15:19).
After the apostles, James the brother of the Lord surnamed the Just was made head of the Church at Jerusalem. James "ruled the church of Jerusalem thirty years". This James, whom the people of old called the Just because of his outstanding virtue, was the first, as the record tells us, to be elected to be bishop of the Jerusalem church
These verses also demonstrate the fraudulent impostering of the Roman Catholic Church in its claim that Peter was "the first pope." It is obvious that at this crucial gathering Peter accepted a lesser role than that shown, by common consent, to James. Had Peter been "the first pope" he would unquestionably have presided over such an assembly as this.
Acts 15:13 And after they had held their peace, James answered, saying, Men [and] brethren, hearken unto me:
James" — Not the apostle, who had been killed by Herod (ch. 12:2), but almost certainly the Lord's half-brother (ch. 12:17; Gal. 2:9), who appears to be the chief of the elders at Jerusalem (Gal. 1:19; 2:12), and president of the conference, also thought to be married (ICor. 9:5).
Acts 15:19 Wherefore my sentence is, that we trouble not them, which from among the Gentiles are turned to God:
"Wherefore my sentence is" — The word krino, "to judge" (as in the Diag.), or "judgment" (RV). As leader of the Jerusalem Church, James spoke with greater authority than Peter and John (Gal. 2:9).
Acts 21:18 And the [day] following Paul went in with us unto James; and all the elders were present.
The Lord's half brother (Acts 12:17), who was considered the leading brother of the Church.
Hegesippus records that James was known as the "Righteous One " who continually prayed in the Temple for the forgiveness of the people
James, the Lord's brother, succeeds to the government of the Church, in conjunction with the apostles. He has been universally called the Just, from the days of the Lord down to the present time. For many bore the name of James; but this one was holy from his mother's womb. He drank no wine or other intoxicating liquor, nor did he eat flesh; no razor came upon his head; he did not anoint himself with oil. He alone was permitted to enter the holy place: for he did not wear any woollen garment, but fine linen only. He alone, I say, was wont to go into the temple: and he used to be found kneeling on his knees, begging forgiveness for the people-so that the skin of his knees became horny like that of a camel's, by reason of his constantly bending the knee in adoration to God, and begging forgiveness for the people. (Eusebius's Ecclesiastical History Book II, 23)
the Lord's brother, later wrote that "the effectual fervent prayer of a righteous man availeth much" (ch. 5:16).
This statement [logion 12] . . . is also at odds with the orthodox tradition of the succession of Peter. It represents nothing less than the lost tradition of the direct appointment of James as successor to his brother.
This saying is not in opposition to the Gospel tradition were Jesus grants Peter the "keys of the kingdom" it does not mean the keys of leadership but the key of knowledge see saying 39 Mathew 16:19 Luke 11:52
Acts 15:13 And after they had held their peace, James answered, saying, Men [and] brethren, hearken unto me:
14 Simeon hath declared how God at the first did visit the Gentiles, to take out of them a people for his name.
15 And to this agree the words of the prophets; as it is written,
It is obvious that James knew of Peter's special commission the Lord had given him ("I will give unto thee the keys [plural] of the kingdom of heaven," Mat. 16:18-19) gave him irrevocably an exclusive responsibility concerning the unlocking of the divine purpose of salvation. Peter would unlock the door of entrance to the kingdom to both Jew and Gentile; a charge which he had faithfully fulfilled (Acts chapters 2, and 10).
But further, James not only accepted Peter's words in this matter — which would have been fully supported by the other apostles — but quoted from two Old Testament prophets (Amos 9:11-12; Jer. 12:15) to prove that a commission such as that given to Peter was inevitable, according to the divine foreknowledge.
These verses also demonstrate the fraudulent impostering of the Roman Catholic Church in its claim that Peter was "the first pope." It is obvious that at this crucial gathering Peter accepted a lesser role than that shown, by common consent, to James. Had Peter been "the first pope" he would unquestionably have presided over such an assembly as this.
"Wherefore observe the greatest caution, that you believe no teacher, unless he bring from Jerusalem the testimonial of James the Lord's brother, or of whosoever may come after him.29 For no one, unless he has gone up thither, and there has been approved as a fit and faithful teacher for preaching the word of Christ, -- unless, I say, he brings a testimonial thence, is by any means to be received. (The Recognitions of Clement. Book IV. False Apostles. Chapter XXXV)
The Lord had earlier instructed his disciples to go "to the lost sheep of the house of Israel" (Mat. 10:6; 15:24). James later wrote "to the twelve tribes which are scattered abroad" (ch. 1:1).
