Really?
Same kind of way of answering when discussing something with a communist/socialist/liberal/progressive...They have NO answer and they lost the argument!! So they spin, and spin, and spin, and spin and talk nonsense!!
On the contrary, I gave you quite the concrete, specific answer. James, brother of Jesus, so described in the Bible itself. Jude, brother of James, so described in the Bible itself. Book of James. Book of Jude.
It just appears to me, that you have a rather excessively negative reaction to this statement of fact, to the point of violating forum rules. You might want to check that tendency. There are ways to disagree that don’t violate them.
