I stand corrected about the anointing of the very sick rather than the dead.  That was an unfortunate slip.   In Greek Orthodox tradition, it is recommended that there be 3 to 5 priests present but 1 will do in emergencies and the holy oils are blessed by the priests, not the bishops.  I suggest that as in most of the sacraments, the power to confect them is given to each of us at Baptism.  Though leadership in our church is very necessary, Clericalism to dispense and convect sacraments is a big disadvantage and its reason for continued presence is self preservation of an authoritarian but not authoritative structure.
