Then use the name of Jesus and call Mary *mother of Jesus*, just like God the Holy Spirit did when HE inspired Scripture.
Then don't use the word Trinity, or any English translation of the bible.
Your position is untenable, since the Holy Spirit did not "fail" in not explicitly saying "Mother of God." I reject that interpretation since I know that the passages entail a necessary connotation. Mary is the "Mother of the Lord." (Lk 1:43) Mary is the Mother of God.
