The hierarchy of angels, priests and deacons was not considered sufficient to perfect the saints, but the spiritual ministries taken from Ephesians 4:11 were developed for this end. These were defined to be four in number (as against the interpretation of a fivefold ministry): (Apostle or) Elder, Prophet, Evangelist, and Pastor (or Teacher). These were referred to as the "border" or "colour" of the ministry and were discerned by prophecy. Since these ministries were supposed to indicate something about the fundamental character of the minister personally, the border could not be changed once defined.
