This Sunday we celebrate the Assumption of the Blessed Virgin Mary, body and soul, into heaven. We might wonder why the Church insists on the importance of this event in Mary's life and in the life of the Church. Meditating on the "twin feast" of the Solemnity of the Ascension, when we commemorate the Ascension of Jesus's body into heaven, helps us to make sense of why it's so important that Mary -- body and soul -- has joined her Son, who is also there with his human body, in heaven.
