Mary and Christ's suffering 

Mary's participation in Christ's suffering began with the annunciation, when she was asked to give God a human body, more properly, a human nature. In other words, will you make God capable of suffering? God though he was, he learned obedience in the school of suffering. God could know experimentally what suffering was only by taking a body. So the Blessed Mother is asked, 'Will you make it possible for your creator to suffer?' Think of a mother, for example, who gives to a young son or daughter an automobile at the age of nineteen, which a short time afterward is the cause of a wreck and permanent injury. Would the mother ever forgive herself? And here Mary has to say yes, I will let him suffer.
