We know Jews highly valued genealogy, and made a point of recording it (So and so begat...). We also know the only person “born of Mary” (Matthew 1:18) was Jesus. We also know that John the Baptist was the son of Elizabeth “she bore a son” (Luke 1:57).
No place else in Scripture does it say Mary bore other children, nor does it say other children were “born of” Mary.
Additionally, should Jesus had siblings born of Mary, would they not have likely had children and so on? However, we don’t see that, either in the Bible, or other accounts. The Bible appears to indicate the line of both Joseph and Mary stop at Jesus (and John the Baptist, respectively). If it didn’t, when did it? Where were they at Pentecost, the crucifixion, or other key moments in His ministry?
It is my personal opinion there were no other children or half-siblings. I also believe the Apostles had no children, though we know Peter was/had been married.
Scripture doesn't have to say the exact words "Mary bore...." as the text tells us she and Joseph had other kids.
Matthew 13:55 gives us the names of His brothers.
Paul noted in Gal 1:19 that James was the brother of Christ.
Your personal opinion is at odds with the Word.
I don't think we know that at all. They are named in Mattew 13:55. I am not into Greek, but from what I understand, the word for physical brother was used for them. The word for cousin was not used. I also believe that Adam and Eve had a whole huge bunch of kids. Only a few are named, because the Bible was not written to give a blow by blow description of history, nor was it written for our curiosity. It was written, to give us the information necessary, to respond to the gospel. I believe Mary was a sinner, saved by grace, just like all who are saved by grace. She does not occupy a place in Heaven higher than anyone else. If others want to believe something different, so be it. I just don't accept it myself.
Psalm69:8 I have become a stranger to my brothers, an alien to my mother's sons.
Matthew 1:24-25 When Joseph woke from sleep, he did as the angel of the Lord commanded him: he took his wife, but knew her not until she had given birth to a son. And he called his name Jesus.
Matthew 12:46-47 “While He was still speaking to the multitudes, behold, His mother “and brothers” were standing outside, seeking to speak to Him. And someone said to Him, “Behold, Your mother and Your brothers are standing outside seeking to speak to You.”
Matthew 13:55 “Is not this the carpenter’s son? Is not His mother called Mary, and ‘His brothers James and Joseph and Simon and Judas?”
Mark 6:2-3 “And when the Sabbath had come, He began to teach in the synagogue; and the many listeners were astonished, saying, “Where did this man get these things, and what is this wisdom given to Him, and such miracles as these performed by His hands?... “Is not this the carpenter, the son of Mary, and ‘brother of James, and Joses, and Judas, and Simon? Are not ‘His sisters’ here with us?”
John 2:12 “After this He went down to Capernaum, He and His mother, and ‘His brothers’, and His disciples; and there they stayed a few days.”
Acts 1:14 “These all with one mind were continually devoting themselves to prayer, along with the women, and Mary the mother of Jesus, ‘and with His brothers’.”
1 Corinthians 9:4-5 “Do we not have a right to eat and drink? Do we not have a right to take along a believing wife, even as the rest of the apostles, ‘and’ the brothers of the Lord, and Cephas?”
Galatians 1:19 But I did not see any other of the apostles except James, ‘the Lord’s brother’..

Short Definition: a brother
Definition: a brother, member of the same religious community, especially a fellow-Christian.
Here is a link to the occurrences of the Greek word *adelphos*.
http://biblehub.com/greek/80.htm
The word *sister* (adelphe) in the Greek is the same.
http://biblehub.com/greek/79.htm
The word used is *brother* not *cousin*.
It can't mean a member of the same religious community in the context in which they occur, because then that would mean every man in Israel could be identified as Jesus' brother. So that would not identify Jesus as anyone in particular's brother.
It's not going to mean *brother in Christ* as that concept was not yet in place and the Jews, who knew Jesus as a Jew and knew His brothers as Jews, would not even begin to understand the new birth and what being in Christ meant.
They didn't even understand who JESUS was, much less being a *brother in Christ*.
The only definition left then, is to mean physical brother.
And it would not be *cousin*.
The word for *relative* that is used for Elizabeth is *suggenes*, not *adelphe*.

Jesus had YOUNGER brothers and sisters. Mary was still alive after the crucifixion. There is zero evidence of Joseph divorcing Mary. What magic does catholicism offer to account for the brothers and sisters of Jesus, WHO WERE YOUNGER THAN JESUS?
