Yet again you give me a verse that does not call James the son of Mary or of Joseph. There were two James in the NT. One was the son of Zebedee and the other the son of Mary, wife of Clopas.
Paul’s use of the word brother here is not regarding a biological connection but a spiritual one.
Another Fail.
Paul the apostle knew who James was and who Yeshua was.
Nice try at deception. James the apostle was a blood brother of the Lord according to Paul not spiritual; that was a real foul ball.
Luk 8:19 Then came to him his mother and his brethren, and could not come at him for the press.
Luk 8:20 And it was told him by certain which said, Thy mother and thy brethren stand without, desiring to see thee.
According to you, Jesus' mother shows up with Jesus' spiritual brethren...But, they can not get any where near him...
Luk 8:21 And he answered and said unto them, My mother and my brethren are these which hear the word of God, and do it.
According to you then, Jesus denies his spiritual brethren along with his mother, points to the crowd and says 'these are my spiritual brethren, right here in front of me...THEY (not the spiritual brethren outside with my mother) hear the word of God and do it...So then we have to conclude the 'other' spiritual brethren did not hear the word of God and do it...
And of course to do that would be ridiculous...It doesn't make the least bit of sense...It's not believable...The idea that your theory could be correct is well beyond the realm of possibility...
