John 19:26-27
When Jesus therefore saw His mother and the disciple standing by, whom He loved, he saith unto his mother, woman behold thy son! Then saith he to the disciple, behold thy mother!.....
So you agree that Mary is mother to ALL Christians
So you agree that Mary is mother to ALL Christians"
Let's see the whole thing, John 19:25-
Near the cross of Jesus stood his mother, his mother's sister, Mary the wife of Clopas, and Mary Magdalene. When Jesus saw his mother there, and the disciple whom he loved standing nearby, he said to his mother, "Dear woman, here is your son," and to the disciple, "Here is your mother." From that time on, this disciple took her into his home.
This is sufficient to say: If you are a Christian that God loves, then Mary is your mother and you are her son. Here is what she says at the beginning of His public ministry, not at her command, but at her request, John 2:4-5"Dear woman, why do you involve me?" Jesus replied, "My time has not yet come." His mother said to the servants, "Do whatever he tells you."
Let's ad some more.
Gen3:20 Adam named his wife Eve, [~living] because she would become the mother of all the living.
1 Cor 15:45-47 So it is written: "The first man Adam became a living being"[Gen. 2:7]; the last Adam, a life-giving spirit. The spiritual did not come first, but the natural, and after that the spiritual. The first man was of the dust of the earth, the second man from heaven.
The Life giving Spirit called the mother of all the living(those He loved) Mary. What God says, and I agree is:
The mother of all the living is Mary, including Christians.
