>> “Do you believe Mary was the Mother of Jesus Christ?” <<

Only of his Earthly body.
The Logos exists eternally, and has no mother.
Mary was the mother only of the “kinsman redeemer” of mankind, not of the Logos.
Mother of God is a pagan title, used only by lost pagans.

Matthew 1:20
But while he thought on these things, behold the angel of the Lord appeared to him in his sleep, saying: Joseph, son of David, fear not to take unto thee Mary thy wife, for that which is conceived in her, is of the Holy Ghost.
You "sola scriptura" guys sure ignore a lot of that "scriptura" that Luther and other apostates/heretics could not accept.
Apparently you are familiar with neither the Old nor the New Testament to speak such heresy.
