Where did you read that? Or did you mistype.
Most of the comments in search are in agreement that Mary the mother of James and Joses is the same as Mary the wife of Cleopas
Mathew 27
56
Among which was Mary Magdalene, and Mary the mother of James and Joses, and the mother of Zebedee’s children.
Jn 19:25
“And there were standing by the cross of Jesus His mother and His mother’s sister, Mary of Cleophas, and Mary Magdalen.
James is described as the son of Alphaeus who may or may not be Cleopas
Cleophas is the brother of Joseph.
I have no doubt that James and Joses was the sons of Mary the wife of Cleopas.
And as far as the four so called brothers of Jesus are concerned Josepth is not mentioned as the father of any of them.
You would think he would be called the father of one or two of them if they were children of Mary.
On this hand of FR RF, there are the believers in the Jesus of Nazareth as revealed in the Bible. On the other hand are wishful-but-carnal believers who don’t hesitate to question the Written Word (the Bible) and form their own independent opinions, or choose to honor their sects’ traditions above the Bible as regarding Jesus and what the Bible has revealed about Him to the sheep of HIS pastures.
I used to fall in the second category. Until I ran smack dab into the Way, the Truth, and the Life and could no longer downplay or alter His written Word. That was because I had changed my mind utterly and died to myself as lord that day in order to be born of the Spirit Who goes wherever He wills and Who wrote the Bible utilizing various willing men led perfectly by the Spirit of God. But you probably know how the Born Again tend to see Biblical things differently than the rest of humanity.
