Ummmmm, Mary, the mother of God. . . . not quite. There is NOTHING scriptural about this term. Look it up. Mary, the mother of Jesus is correct, but NOT the mother of God. I don't know what the big deal is about this. Scripture is clear that there is ONE mediator between God and man, Jesus Christ.
1Ti 2:5 For there is one God, and one mediator between God and men, the man Christ Jesus;
And I hope I don't have to post Scriptures proving that the Bible declares that there is ONE God and there is no other. Mary was just a human being. Just like you and me, nothing special.
Check this out:
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.
Mary, the mother of Jesus, was with the disciples on the day of Pentecost. She was one of those who received the Holy Ghost. If she was in the position that some put her in, then why did she need the Holy Ghost? Because she was a human who needed to be saved, just like you and me.
