However, there is no other distinction in scripture where someone is called the "Lord's brother."
You might be confused about my post, but there's no confusion about me - I'm a she.
She/He argues the use of "brother of" to support her side of the debate that says it's use was significant in calling all converts "brother and sisters," even with the distinction in Galation's 1:19 which says, "...the Lord's brother."
However, there is no other distinction in scripture where someone is called the "Lord's brother."
OK, let's make it simple... Let's just look at Acts 1:14 and 1:15, which I posted earlier.
Act 1:14 These all continued with one accord in prayer and supplication, with the women, and Mary the mother of Jesus, and with his brethren. link
Act 1:15 And in those days Peter stood up in the midst of the disciples, and said, (the number of names together were about an hundred and twenty,) link
Answer this, do you honestly believe that Mary had 120 children at the time?
I already posted that James, Joseph, Jude,and Simon, were the sons of Mary the Clopas – sister of Virgin Mary – whose husband was Clopas (Alphaeus.) Read Mark 15:40 and Mark 3:18, which I also posted.
Let's look at Act 1:13
Act 1:13 And when they were come in, they went up into an upper room, where abode both Peter, and James, and John, and Andrew, Philip, and Thomas, Bartholomew, and Matthew, James [the son] of Alphaeus, and Simon Zelotes, and Judas [the brother] of James.
James, the son of Alphaeus (Clopas) whose wife is Mary of Clopas sister of Virgin Mary... and as you can see, their brothers are Judas and Simon who are also the sons of Clopas.
Let's look at this one:
Mark 6:3 Is not this the carpenter, the son of Mary, the brother of James, and Joses, and of Juda, and Simon? and are not his sisters here with us? And they were offended at him. link
Is not this the carpenter, the son of Mary? THE SON of Mary... it doesn't say whether He is the oldest or the youngest son... just the SON of Mary... ONE SON, so there's no question Jesus is the Son of Mary. So, why then, doesn't the NT say something like... Is not this the carpenter, the son of Mary and Mary's other sons James, Joses, Juda, and Simon?
Nope, it says... the Son of Mary the brother of James and Joses and Juda and Simon the Zealot (which you already know are the children of Clopas and Mary's sister. Making James, Joseph, Juda, and Simon, cousins.
So again:
Act 1:13 And when they were come in, they went up into an upper room, where abode both Peter, and James, and John, and Andrew, Philip, and Thomas, Bartholomew, and Matthew, James [the son] of Alphaeus, and Simon Zelotes, and Judas [the brother] of James.
I'm going to repeat this again. The Bible NEVER mentions that Mary had other sons or daughters, and never once says, “Mary's other children” or “Mary's other sons and daughters.” What you see is, Jesus brother/s - and I already explain the meaning of the word brother in my earlier post.
