Mary had four other sons, Joseph, James, Jude, and Simon. Because of the "virgin birth", Joseph was not the father of Jesus so these were the half brothers of Jesus.

"1:18 Now the birth of Jesus Christ happened this way. While his mother Mary was engaged to Joseph, but before they came together, she was found to be pregnant through the HOLY SPIRIT."

Ehmm, I'm no expert in religion. But doesn't this seem kinda...weird? Did they call Chads "Holy spirits" back in the days? :p

Were Mary actually just riding the cock carusel and made Joseph her beta provider?
