In Scripture, the Holy Spirit saw fit to name her, Mary, mother of Jesus.
Jesus only ever referred to he as “Woman”.
Neither Jesus nor the Holy Spirit ever assigned any other title to her. Calling her “ Mother of God” is man’s construct, obviously believing the the Holy Spirit did not do a good enough job inspiring Scripture.
Excellent. Thank you for these very good observations. You caused me to recall that when Jesus was told Mary was outside of a gathering where he was speaking, He noted that "Here is my mother and brothers." to the audience. Hmmm.
But do you believe that Jesus is God made man and Mary was his mother? "Behold your mother" is good enough for me. I hope it is for you too.
