There is one Church, with visible & invisible aspects.
Like a person, with a body & a soul.
Like a Sacrament, with physical & divine "matter".

Priests didn't begin with the disciples; they had existed in the Jewish faith for a long time. God used this aspect.  Priesthood was perfected as a result of Jesus's own example of priest and victim. 

If more people understood what the Church means by "common" & "ministerial" priesthood, they'd be less focused on "priest" topics. They'd be less "clerical" in their mindset. Yes, many here are "clerical" because they think wrongly that everything centers on the cleric.

Beyond "understanding" what the distinctions and demands of each (the commmon and ministerial priesthood) are - if these same people focused on living heroically their own common priesthood they'd have no time, desire or energy to wax on about priests.  

They'd be very happy and very tired b/c they'd be offering themselves as priest and victim in their ordinary life.
