When was the last time that you attended a baptism.  The baptized individual is anointed on the crown of the head as "priest, prophet, and king.'  The commissioning that occurs in baptism and is completed in confirmation, confers baptismal priesthood or "the priesthood of all the faithful".  The community of the baptized IS the priestly community.  As priestly people we represent God to the world and bring the concerns of the world before God.  It shares in the one priesthood of Christ that is laid out in the Letter to the Hebrews and reprised at length in "Lumen gentium."

The baptized layperson is NOT LESS PRIESTLY than the ordained; it is simply that he or she has not added to the baptismal priesthood the particular responsibilities of servant leadership that denotes the role of the ordained.  And the ordained minister presides at the Eucharist because he is called to be the servant leader of those, the laity, whose task it is to sanctify the world.
