Fair enough. In the Lutheran tradition, the clergy is empowered to administer the Sacraments directly by the power of the holy Spirit and not through a belief in the authority of a magisterium.
The entire idea of sacraments is God using normal people and matter in order to bring His Power into the world. To believe God can work through a man in order to change bread into flesh, but not that He works through man to change man into priest seems inconsistent. IMO.
