tven beyond modern conversational convention, the distinction between “stepbrother” and “brother” didn’t even exist in classical or koine Greek.
This is why Orthodox tradition, which of course operates in the original language of the New Testament, has always held that the relatives of Jesus referred to in the Gospels were his stepbrothers, although western tradition following St. Jerome inclines to the cousins/Aramaic thesis.
