Of course not!!! There's a difference between "mother of Jesus" and "mother of God". But How about in Luke Chapter 1, did Elizabeth make a mistake for saying such?: 41 And it came to pass, that, when Elisabeth heard the salutation of Mary, the babe leaped in her womb; and Elisabeth was filled with the Holy Ghost: 42 And she spake out with a loud voice, and said, Blessed art thou among women, and blessed is the fruit of thy womb. 43 And whence is this to me, that the mother of my Lord should come to me? I guess this was the passage the Catholics are using for calling Mary the mother of God. Thanks.
