Our Lady, Mother of Sweet Sorrow 2

Our lady's hands are holding Jesus up, but at the same time, they indicate humility and deference to Him.  In the Byzantine Church we cross our arms over our chests when approaching Holy Eucharist.  In the Latin Rite we cross over our hands when we are  unable to receive Jesus' Body and Blood.  In both cases the crossing of hands is an act of reverence to God.  Religious art, in the west particularly, show saints' arms in this posture, when God is before them.  For instance, in Fra Angelico's Annunciation, our Lady has her arms crossed, because the Holy Spirit is coming upon her.  
As humble as our Lady's posture is, however, as humble as our own postures must be before God, Jesus is not lofty about His greatness.  The way Jesus is holding His mother's face is exactly how my Gabriel touches mine, right before he pulls my face into his for a kiss.  Jesus is the same way with us.  He came as a baby, utterly helpless and in need of love.  He comes to us now in the humble form of Bread and Wine so that we are not afraid to come to Him and tell Him our dreams and troubles.  He is the Almighty God, but most of all, He longs to take our faces into His hands and bestow upon us a kiss of eternal love.  On earth this can only be the Eucharist!  Amazingly, in Heaven, this kiss is also the Eucharist, that is, eternal union with the Almighty God through Jesus Christ.
