Mary, by the time her firstborn son's ministry started, had given birth through Joseph to at least four other boys and at least two girls for a family composed of at least seven children.
But doesn't Jesus say that his relatives are in fact brother and sisters of another mother? They boys are His cousins and girls family further removed, residing in Joseph's house.
This view is held by the orthodox and catholics.
Mary was a perpetual virgin.
