Yes, scripture, early church documents (including a quote from Pope Clement), and early secular documents confirm that Jesus had physical half-brothers.Matthew 13:55: “Is this not the carpenter’s son? Is not His mother called Mary? And His brothers James, Joses, Simon, and Judas?"There are other verses (I'll get them if you want) that refer to the disciples and then again to James, the brother of Jesus. That's proof that in these instances "brother" wasn't being used in the larger Christian sense.Mark 6:3: “Is this not the carpenter, the Son of Mary, and brother of James, Joses, Judas, and Simon? And are not His sisters here with us?”
From a secular viewpoint, the historian Josephus is clear on the fact that James is the physical (half) brother of Jesus. Josephus wrote on the death of James about 90 AD.
The idea that Jesus had no half-siblings developed several hundred years after the church was founded, and is in profound disagreement with the early teachings of the church.
Jesus had siblings. Mary was not forever virgin. It's rather clear from both the literal language and context of the Scriptures. Just a few examples:
Matthew 1:24-25: "Then Joseph being raised from sleep did as the angel of the Lord had bidden him, and took unto him his wife: And knew her not UNTIL she had brought forth her firstborn Son: and he called His name, Jesus!"
Matthew 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?"
Matthew 27:56: "Among which was Mary Magdalene, and Mary the mother of James and Joses, and the mother of Zebedee's children."
Mark 3:31: "There came then His Brethren and His Mother, and standing without, sent unto Him calling Him."
John 2:12: "After this He went down to Capernaum, He, and His Mother, and His Brethren, and His disciples: and they continued there not many days."
