these infancy stories correctly understood are anything but innocuous,edifying accounts of the child Jesus

Here is more of what Hans Kung had to say about the two narratives about the Birth of Jesus, continuing from where I left off last night. 

Within the scope of the present work,  these few references must suffice to confirm the fact that these infancy stories correctly understood are anything but innocuous,edifying accounts of the child Jesus.  They are stories of Christ, based on profound theological reflection, to be used in a carefully planned proclamation, seeing to portray artistically, vividly and in a highly critical light the true significance of Jesus as Messiah for the salvation of all the nations of the world:  As Son of David and new Moses, as communicator of the Old Covenant and initiator of the New, as Saviour of the poor and as true Son of God.  Here obviously is not the first phase of a biography of Jesus or a precious family history.  It has such more the character of a Gospel;  a message of invitation, according to which the Old Testament promises were fulfilled in Jesus, the chosen one of God,  who did not provide any detailed political prescriptions and programs, but in his very existence, his speech his action and suffering, set up an absolutely concrete standard at which an in his individual and social action can confidently aim.
