To call Mary the mother of God is not biblical. As far as I can recall, the Bible never calls her that. Because of the two natures of Christ in one Person, the most we can say, in order to avoid heretical views, is to say that Mary is the mother of Jesus Christ, which does not deny that His deity was present at His conception in her womb (indeed, this is why the Holy Spirit was involved in her conception). This also applies to the cross. We can't say that God died on the cross, since God is incapable of dying. Again, the best we can do, keeping the hypostatic union in view, is to say that Jesus Christ died on the cross. How Jesus was able to actually, physically die on the cross (which He did), and yet maintain the integrity of the hypostatic union (which we must), is not something God has explained to us - probably because we wouldn't understand it, anyway.
