The Epistles relate the characteristics and responsibilites of a good bishop. Nowhere is it implied that any are to hold a special representation of Christ (other than that of us all, the priesthood of believers) to the rest of us.
Then why does it say to obey those who have rule over you as they are watching out for your souls? And I might add you're in for little trouble with St. Paul here about representation of Christ.
"For, what I have pardoned, if I have pardoned any thing, for your sakes have I done it in the person of Christ." 2nd Cor. 2:10
