I was reading again from Henry Chadwick’s The Early Church. He cited St. Paul’s list of a sevenfold hiearchy of orders- apostles, prophets, teachers, miracle-workers, healers, helpers, and administrators in 1 Cor. 12:28, saying that in Paul’s generation the first three- apostles, prophets, and teachers were the chief “‘orders.’” He went on to say that 60 or 70 years later in the age of Ignatius, the bishop of Antioch, the three chief orders had transitioned into bishop, presbyter, and deacon. I see the correlation between apostle and bishop since we believe they are the apostles’ successors, but to me I guess it looks like prophets were replaced by the helpers or administrators (deacons). Did Paul’s term “teachers” refer to presbyters? Also, the other major issue I’m trying to get a good grasp of is how the distinction between bishops and priests came about, or if there even was one from the beginning. This is how I approach it, but correct me if need be-Christ instituted the priesthood/presbyterate (episcopate more accurate?) on Holy Thursday with the apostles who were basically the first bishops and they contained the fullness of the priesthood, as today’s bishops do and as bishops have throughout history. I don’t understand what happened from there on out.
