The sacrament of holy orders is conferred in three ranks of clergy: bishops, priests, and deacons.
Bishops (episcopoi) have the care of multiple congregations and appoint, ordain, and discipline priests and deacons. They sometimes appear to be called “evangelists” in the New Testament. Examples of first-century bishops include Timothy and Titus (1 Tim. 5:19–22; 2 Tim. 4:5; Titus 1:5).
Priests (presbuteroi) are also known as “presbyters” or “elders.” In fact, the English term “priest” is simply a contraction of the Greek word presbuteros. They have the responsibility of teaching, governing, and providing the sacraments in a given congregation (1 Tim. 5:17; Jas. 5:14–15).
Deacons (diakonoi) are the assistants of the bishops and are responsible for teaching and administering certain Church tasks, such as the distribution of food (Acts 6:1–6).
In the apostolic age, the terms for these offices were still somewhat fluid. Sometimes a term would be used in a technical sense as the title for an office, sometimes not. This non-technical use of the terms even exists today, as when the term is used in many churches (both Protestant and Catholic) to refer to either ordained ministers (as in “My minister visited him”) or non-ordained individuals. (In a Protestant church one might hear “He is a worship minister,” while in a Catholic church one might hear “He is an extraordinary minister of Holy Communion.”)
Thus, in the apostolic age Paul sometimes described himself as a diakonos (“servant” or “minister”; cf. 2 Cor. 3:6, 6:4, 11:23; Eph. 3:7), even though he held an office much higher than that of a deacon, tha
