Really??
What other children were traveling with St. Joseph and the Blessed Virgin when they returned to the temple to search for the Christ Chlld?
The bible does not note in the passage you refer to. But it does note their children in other passages. And please, don’t appeal to the Catholic talking points that brother can mean more than a family brother. The context of the text tells us Joseph and Mary had other children. The Greek also tells us this as well.
It doesn't tell us so it's not relevant.
What possible difference could it make?
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?
Matthew 13:56 "And His sisters, are they not all with us? Where then did this man get all these things?"
Mark 6:3 "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?"And they took offense at Him.
What does Matthew 13:55 say about it?
You actually think that is relevant...?
It is an omission of content, not proof of anything...
So when Scripture tells us Jesus did something and doesn't mention that the twelve apostles were there with him, they weren't actually there ?
Seriously?
We don't know because the bible is silent on the matter.
Most likely friends and relatives (remember Elizabeth?) kept an eye on the children, so that Mary and Joseph could hurry back and search.
The fact that they went so far, before noticing that Jesus was not with them, would seem to indicate that they were quite occupied with small children.
Mark’s account, of the Lord preaching to his home town, shows that the locals were stunned to see how different Jesus was from the rest of his family. They had known the whole family for years.
