Scott,
Some info to look over.....
Some claim that Jesus had siblings. Who are they?
Brothers, cousins! Which is it?
[2] Now the names of the twelve apostles are these; The first, Simon, who is called Peter, and Andrew his brother; James the son of Zebedee, and John his brother;
[3] Philip, and Bartholomew; Thomas, and Matthew the publican; James the son of Alphaeus, and Lebbaeus, whose surname was Thaddaeus;
[4] Simon the Canaanite, and Judas Iscariot, who also betrayed him.
1)Simon BarJona
2)Andrew BarJona
3)James Zebedee
4)John Zebedee
5)Philip
6)Bartholomew
7)Thomas
8)Matthew
9)James Alphaeus (the Less)
10)Jude Thaddeus (Lebbaeus)
11)Simon the Cananite (Zelotes-the Zealot)
12)Judas Iscariot
So we have the BarJona Brothers, the Zebedee Brothers, two Jameses, one a Zebedee, the other the Less because he was called secondly; we have two Judases-one the son of destruction, and the other the "brother" of Jesus. We have two Simons, one Simon Peter, and the other the Cananite.
Matt.13
[55] Is not this the carpenter's son? is not his mother called Mary? and his brethren, James, and Joses, and Simon, and Judas?
The verse above shows that James, Joses, Simon and Judas are either His brothers or relatives of some kind.
At the cross we see: Mary Magdalene, Mary(same as Matt 13:55)the mother of James and Joses, and Mrs. Zebedee.
From Mark 15:40(see below)we see that Mary, the mother of James and Joses is the mother of James the Less. We know from the gospel of John that Jesus' mother is there. So if James the Less and Joses cannot be Jesus' blood brothers because we know from Luke6:15 that James the Less is the son of Alphaeus, not the son of Joseph. However if Blessed Mary, and Mary the mother of James the Less were related, then that would make Jesus and James the Less brethren or brothers and that is just what we see in John 19:25 (see below)where it states that Jesus' mother is the sister of Mary of Cleophas.
Note also that Luke 24:18 has Jesus appearing to a disciple named Cleop(h)as on the road to Emmaus. (Could this be James the Less, or Jude Thaddeus?)Rather than actually being brothers, they too may be cousins.
Matt.27
[56] Among which was Mary Magdalene, and Mary the mother of James and Joses, and the mother of Zebedee's children.
Mark.6
[3] Is not this the carpenter, the son of Mary, the brother of James, and Joses, and of Juda, and Simon? and are not his sisters here with us? And they were offended at him.
Mark.15
[40] There were also women looking on afar off: among whom was Mary Magdalene, and Mary the mother of James the less and of Joses, and Salome;
Mark.16
[1] And when the sabbath was past, Mary Magdalene, and Mary the mother of James, and Salome, had bought sweet spices, that they might come and anoint him.
Luke.6
[15] Matthew and Thomas, James the son of Alphaeus, and Simon called Zelotes,
[16] And Judas the brother of James, and Judas Iscariot, which also was the traitor.
Acts.1
[13] And when they were come in, they went up into an upper room, where abode both Peter, and James, and John, and Andrew, Philip, and Thomas, Bartholomew, and Matthew, James the son of Alphaeus, and Simon Zelotes, and Judas the brother of James.
Acts.12
[2] And he killed James the brother of John with the sword.
[17] But he, beckoning unto them with the hand to hold their peace, declared unto them how the Lord had brought him out of the prison. And he said, Go shew these things unto James, and to the brethren. And he departed, and went into another place.
Here James Zebedee is martyred. (James the greater)
Jude.1
1] Jude, the servant of Jesus Christ, and brother of James, to them that are sanctified by God the Father, and preserved in Jesus Christ, and called:
John.19
[25] Now there stood by the cross of Jesus his mother, and his mother's sister, Mary the wife of Cleophas, and Mary Magdalene.
Matt.27 [56] Among which was Mary Magdalene, and Mary the mother of James and Joses, and the mother of Zebedee's children.
So it seems to me that at the cross was Mary, Jesus' mother; Mary, the wife of Cleophas (Blessed Mother's sister), Mary Magdalene and Mrs. Zebedee (among others)
