Elizabeth called Mary the mother of my Lord surely that is biblical and implies that Mary is the mother of God since the Lord is in fact God. When Elizabeth heard Mary's greeting, the baby leaped in her womb; and Elizabeth was filled with the Holy Spirit. And she cried out with a loud voice and said, "Blessed are you among women, and blessed is the fruit of your womb! And how has it happened to me, that the mother of my Lord would come to me? For behold, when the sound of your greeting reached my ears, the baby leaped in my womb for joy. And blessed is she who believed that there would be a fulfilment of what had been spoken to her by the Lord." (Luke 1:41-45) yet for us there is but one God, the Father, from whom are all things and we exist for Him; and one Lord, Jesus Christ, by whom are all things, and we exist through Him. (1 Corinthians 8:6)
