razeontherock,
Once more, the question that you absolutely refuse to even acknowledge: How do you know that the author of the book of James was the half-brother of Jesus, and that he was the one who led the church in Jerusalem?
How many times have I repeated myself, that the Bible exists solely to record what had been recited in the Churches for decades before it was ever written down?
Please show me where the Bible asserts the point in question, that the writer of the Book of James was the half-brother of Jesus. If the Bible nowhere asserts the claim you say you know is true, then you cannot turn to it as your evidence.
You may claim that the Bible is simply copying down what had been recited for years, but how do you know that this is true? How do you know that the epistles of Peter correctly record what the church said for years, but the apocalype of Peter does not? How do you know that Matthew correctly records what the church taught, but the Gospel of Thomas does not?
That James served in the first Church, that was in Jerusalem?
I agree that the book of Acts teaches this.
But as Acts is widely regarded to be fiction, I wouldn't put much weight on that. Besides the doubtful book of Acts, you have no real evidence that this is so.
Are you trying to tell those people they don't know who James was? Really??
Even if the leader in Jerusalem was named James, how do you know that the James that wrote the book of James was that same James? You refuse to deal with that question, don't you? You just pretend that question was never asked, don't you?
But the question does not go away. How do you know that the James that wrote the book of James was that same James that led the church in Jerusalem?
