Of course you won't!
Now tell us why you capitalize "Mother"?
An Accident? I think not.
Would you write, "Nor will I forget James, the half-brother of Jesus, and His Mother."?
Oh! That's right... it's the Ever "Virgin" business (pun intended).
But you seem to reject what is in the Bible in deference to what is not in the Bible.
“Isn’t this the carpenter? Isn’t this Mary’s son and the brother of James, Joseph, Judas and Simon? Aren’t his sisters here with us?’ And they took offense at him” (Mark 6:3).
(See also Mat 12:46 and 13:55 and 56, Mark 3:31, Luke 8:19, John 7:1-10, Acts 1:14, I Cor 9:5, Gal 1:19)
You don't believe those words, do you? They have a different meaning* for you, don't they? That's not what it says, is it?
Make your case. Try to refrain from a baseless or personal counter-attack.

* In each instance cited, the specific Greek word for “brother” is used. While the word can refer to other relatives, its normal and literal meaning is a physical brother. There was a Greek word for “cousin,” and it was not used.
