The routing list for inner-office memos needs to be updated...
When therefore we read in the writings of Saint Bernard, Saint Bernardine, Saint Bonaventure, and others that all in heaven and on earth, even God himself, is subject to the Blessed Virgin, they mean that the authority which God was pleased to give her is so great that she seems to have the same power as God. Her prayers and requests are so powerful with him that he accepts them as commands in the sense that he never resists his dear mother’s prayer because it is always humble and conformed to his will.... St. Louis de Montfort, in Treatise on True Devotion to the Blessed Virgin, #27, 246.

This does not mean Mary is God's superior. Mary is God's handmaid ---a verse we read every day in evening prayer (Luke 1:46-55, also called the Canticle of Mary and, in the Byzantine tradition, the Ode of the Theotokos.) We Westerners pray it every day in the evening, but the Byzantines pray it in the morning.
People who sing or recite that Mary is the handmaid of the Lord every day of their lives are, shall we say, familiar with her status as handmaid. Not news to us! The paradoxical part about Jesus being "subject" to her means that the person Jesus (who was God and Man) was subject to his mother. And, being obedient to the Commandments, He honored her, and honors her still because she's still His mother.
I don't blame you for not getting all the implications of this instantly. I sure didn't. Most people don't situate this in enough context (not just textual context, but wide cultural context) to get a true spiritual perspective on Jesus being both Mary's Son and her Lord.
It's, like so many things, a paradox. Jesus in His Divine nature was Mary's Creator, in His human nature her descendant. We can marvel in, and delight in, the paradoxes of the Incarnation.
and I...
...do not adore Mary.
