God SUBJECTS HIMSELF to the Blessed Virgin, because it is His Most Holy Will to do so. No one can subject God to anything/anyone. Herein lies the difference.
LBR: Just for the record, do you have a Scripture reference for that?
Metmom, yes, for the record, the wedding at Cana. This illustrates the relationship between Jesus and His mother, and He is the same yesterday, today and tomorrow.
