Legal father
Mary does not have a sister also named Mary, but it is her sister in law, but a sister in law is still a sister Jn 19:25
In Hebrew culture bother means any close relation
Brothers and sisters of Jesus?
They are not the children of Mary!
Is 7:14 a virgin shall conceive and bear a son!
(One son, singular)
James is the son of zebedee, and the other James is the son of Alpheus not Joseph!
Matt 10:2-3
In Hebrew culture any close relative can be called brother or sister, lot was called Abraham’s brother but was his nephew.
Gen 12:5 and Abram took Sarai his wife, and Lot his brother's son..
Gen 13:8 And Abram said unto Lot, Let there be no strife, I pray thee, between me and thee, and between my herdsmen and thy herdsmen; for we are Brothers.
The 12 sons of Jacob are brothers but all are not the children of Leah and all are not the children of Rachel! They had 4 mother’s, These may be brothers but they are simply not the children of One mother and the brothers of Jesus are not the children of Mary!
Jose’s, Simon Salome are children of another Mary!
Mk 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;
Is Mary the mother of James?
If you mean the Blessed Virgin Mary then no. Her sister-in-law, Mary of Clopas, was the wife of Alphaeus (St. Joseph's brother), and mother of Simon, Joseph, and the apostles Judas Thaddeus, and James (the Less, brother of the Lord): Jesus' cousins.
The "sisters" of Jesus refer to women disciples.
Salome, or Mary Salome, was the wife of Zebedee, and mother of apostles John (the beloved), and James (the greater).
Regarding Mat. 13:55 and Mk. 6:3, two of the four "brethren" are James and Judas of Alphaeus (cf. Mat. 10:2-3, Lk. 6:15-16, Act. 1:13). The third, Joseph, is identified in Mk. 15:40 as the brother of James of Alphaeus. The fourth, Simon, is identified in Mat. 13:55 and Mk. 6:3 as the brother of Joseph, James, and Judas of Alphaeus. Therefore, all four are were the sons of Alphaeus, not St. Joseph and the Blessed Virgin Mary.
When Jesus was twelve they went up to Jerusalem, the holy family, Joseph, Mary, and Jesus. Where are the brothers and sisters?
Jesus on the cross gives His mother to John, why? Why not James or a brother? Perhaps the law of Moses requires a mother to be given to the next oldest son? Because he was an only Son!
Only begotten of the Father, only begotten of the Mother.
