I know you did, but I am not sure if Forest Keeper agrees with your answer. IF I understood your answer correctly, you do not object to the proper understanding of Mary being the mother of God, but rather to the fact that using it as a title might lead to deification of Mary. With that I do not have a big problem, -- it's a free country. If you think a title might be confusing, well, don't use it.
Since I believer that God can not be divided, Mary, mother of God, is too imprecise of a term and does potential damage to the eternal preexistence of Christ as well as the unity of the Trinity. I not only think it is confusing, but think it is wrong to use in that way. Using the precise term (and biblical term) Mary, Mother of Jesus or Mary, mother of my Lord helps one to be precise, lets one base one's Christology on the person of Christ and preserves his unity with the Father and the Spirit as well as His eternal preexistence.
