The natural understanding of Mark 6: 3 is that James, Joses, Simon, and Judas were the younger sons of Mary and Joseph. But the wider meaning of ‘brother’ makes it legitimate to hold that James (Gal. 1: 19) and the others were children of Joseph (who disappears from the gospels, perhaps because of old age, after the infancy narratives) by a former marriage, or cousins (cf. 1 Kgs. 20: 32, REB).
