@hazlin @theorytoe @MK2boogaloo @gnarley_boot The actual relation is questionable; there are no records to indicate that the author of the epistle was actually Jesus' blood brother. All we have is the claims within James' own writings, which we know are highly motivated towards his revolutionary aims. It might have been that Paul was less concerned about the potential blood of James and Jesus and a lot more concerned about his own blood should he sufficiently piss off James. Who knows...
St. Augustine sure didn't think much of the epistle of James.
