>>And yet you insist Scripture allows Mary to be called the “mother of the church” and the “mother of God.”<<
I’m sorry that you’re stuck in American culture and don’t get the concept. Jesus was a Jew. You are saying that Jesus did not follow the commandments and “Honor His Mother” when he called her “Woman”. You are calling Jesus a sinner. Poles call their mothers Baba which means Woman. Jesus called his mother the same.
Now I don’t know what flavor of Presbyterian you are that believes that Jesus was a different person when he was an infant than when he died on the cross, nor which flavor teaches that Jesus was a sinner, but I do know that my Presbyterian husband doesn’t believe this stuff.
The devil is guiding whomever is telling you that.
Was Jesus calling His mother a "crone?"
Look up the word "mother" in Scripture and see how many times it was used -- by prophets, by kings, by all sorts of men and women.
But never once by Jesus Christ in reference to Mary.
You're missing what God's word is clearly saying -- Christ's true family is not predicated on blood, but on belief in Him.
