Christianity proclaims the essential good of existence and the good of that which exists, acknowledges the goodness of Creator and proclaims the good of creatures. Man suffers on account of evil, which is a certain lack, limitation or distortion of good. We could say that man suffers because of a good in which he does not share, from which in a certain sense he is cut off or of which he has deprived himself. He particularly suffers when he "ought" -- in the normal order of things -- to have a share in this good and does not have it. Thus, in the Christian view, the reality of suffering is explained through evil, which always in some way refers to a good.- Salvifici Dolores -Pope John Paul II
