Mark 6:3
Jesus Brothers
3 Isn’t this the carpenter? Isn’t this Mary’s son and the brother of James, Joseph, Judas and Simon? Aren’t his sisters here with us?” And they took offense at him.
John 7:2-5
Jesus Brothers Belief
2 But when the Jewish Festival of Tabernacles was near, 3 Jesus’ brothers said to him, “Leave Galilee and go to Judea, so that your disciples there may see the works you do. 4 No one who wants to become a public figure acts in secret. Since you are doing these things, show yourself to the world.” 5 For even his own brothers did not believe in him.
1 Corinthians 15:7-8
James Sees Jesus After His Death
7 Then he appeared to James, then to all the apostles, 8 and last of all he appeared to me also, as to one abnormally born.
Acts 1:13-14
Jesus Mothers and Brothers Pray
13 When they arrived, they went upstairs to the room where they were staying. Those present were Peter, John, James and Andrew; Philip and Thomas, Bartholomew and Matthew; James son of Alphaeus and Simon the Zealot, and Judas son of James. 14 They all joined together constantly in prayer, along with the women and Mary the mother of Jesus, and with his brothers.
James and Jesus other brothers did not believe He was the Son of God...Jesus' brothers did not believe that He was divine...Yet, they would have have known Jesus all their lives...They would have known that He was different...They would also would have known that their brother was a Special One...How could He not be, being who He is?...
In the Gospel of John, Jesus' brothers seem to want Him to do some other miracles in front of His disciples at the Feast of Tabernacles, so Jesus can become more of a public figure...But Jesus' brothers do not believe Him, so we cannot be sure how sincere they are in telling Him to go do more miracles in public...But one thing we can be sure of is that it is very difficult to fool a brother or a group of brothers when you have lived together, played, ate, and done things together all your lives...The family and His brothers would have recognized some things over a period of the thirty years that Jesus lived...They would have seen He could do things that were a little bit different...
James would become a believer, only later...James would work with Peter and meet Paul and, of course, knew much about His Brother...James would become a leader of the early Christian church...James would author the Book of James in the New Testament...Some think that James is the first written New Testament Book...Jesus, other brother, Judas, also know as Jude, would also become a firm believer and write the Book of Jude...James and Peter were the leaders at the Council of Jerusalem when Paul and Barnabas had questions for the early church (Acts 15:1-41)...
When St. Paul mentions James in his first letter to the Corinthians, he does not mention James as James, the disciple...The James, he is writing about is not the James, the son of Zebedee, or James, the son of Alphaeus...This is James the (half) brother of Jesus, who John writes about who doesn't believe in Jesus until he sees His resurrected Brother...Paul has visited and discussed with James these things about His Brother Jesus (Galatians 1:19 and Galatians 2:9) and Paul writes about these things, after talking to James in these meetings...
After James has seen His Brother after His death, He is a believer...We are not given an exact time of James conversion, but we know that right after Jesus ascends to heaven that he is there with the Eleven disciples, which includes Peter, John, James, Andrew, Thomas, Bartholomew, Matthew, (the other disciple) James, Simon, and Judas, the son of James...Jesus mother Mary, James, Jude, and His other brothers join with the Eleven Disciples of Jesus, and more than once (we are told constantly) pray together...No doubt Jesus brothers would be talking to one another, after their Brother's death and James would tell his other brothers how he had seen his Brother, after His death...The family would then all know that Jesus was resurrected after James saw Him...This would make for interesting talk around the dinner table, seeing your resurrected dead Brother, especially after Peter had seen Him (after His death) as well as all the other disciples...Jesus brothers would know Jesus is our Messiah...
There is no doubt, in my mind that growing up with Jesus would be give one a unique childhood...Jesus, brothers and sisters, would have seen a truly remarkable , Brother, Boy and Young Man...They would have seen and heard things no doubt that a normal family would not have seen and heard, because Jesus is divine...And while all the family share the same mother, Jesus Father is God...He is the Son of the Living God...
