In looking at the the analogy between Christ's Ascension and Mary's Assumption, we can conclude that Mary, in dependence on Christ, is the Queen who possesses and exercises over the universe a sovereignty granted to her by her Son.
The title of Queen does not of course replace that of Mother: her queenship remains a corollary of her particular maternal mission and simply expresses the power conferred on her to carry out that mission.
The concern Mary Queen has on mankind can be fully effective precisely by virtue of her glorious state which derives from the Assumption. St Germanus of Constantinople highlights this very well. He holds that this state guarantees Mary's intimate relationship with her Son and enables her to intercede in our favour. Addressing Mary he says: Christ wanted "to have, so to speak, the closeness of your lips and your heart; thus he assents to all the desires you express to him, when you suffer for your children, with his divine power he does all that you ask of him."
One can conclude that the Assumption favours Mary's full communion not only with Christ, but with each one of us: she is beside us, because her glorious state enables her to follow us in our daily earthly journey.
Taken up into heavenly glory, Mary dedicates herself totally to the work of salvation in order to communicate to every living person the happiness granted to her. She is a Queen who gives all that she possesses, participating above all in the life and love of Christ.
