Acharei Moth-Kedoshim: boundries

The names of these 3 parshioth  comes to: " after their deaths, they are called holy" - Acharei Moth Kedoshim Emor.  The recollection of the dead is cleansed of the foibles of the previously living.  Holocaust memorials often take place around this time. The romanticization of the shtetl is an example of selective recall. 

Acharei Moth begins with the Yom Kippur temple service.  It is introduced with a reminder that 2 of Aaron's sons died when they approached the Kodesh. One should not approach the Kodesh at unassigned times! Kodesh is dangerous! Subsequently, the people of Israel are exhorted to be Kodesh. Does their kedushah make them dangerous? In some ways, yes. 

The lethal kodesh of Acharei Moth is too intense, too holy. There are places that even the holiest person cannot go. That does not contradict the quest for holiness, for improvement. Don't worry, you will never get that holy. 

In Kedoshim, the people are instructed to be holy. Boundries are established on behavior, places to avoid because they profane: the corner of the field left to the poor, false oaths, theft, etc., etc. 

This parsha also has an introductory caution:  fear your mother and father, and guard my Sabbaths.  When I was a young teen, this is the verse that Rabbi Hamburger, disciple of Avigdor Miller, quoted to us.  He interpreted it as: it is foremost  to follow Gd's law ( and convince other Jews to do likewise), but try not to hurt your parents too much in the process.  He corrupted my understanding of this pasuk forever. 

This verse connects with the two goats of Yom Kippur, but which is the goat of expiation (Chatath) and which is the scapegoat ( Mishtaleiach).  Parents? Shabbath? sometimes one, sometimes the other?  I am confused. I need boundries to keep me  from the dangerously holy.
