Following up on my previous reply.
I’ll just mention the teaching as I have received it:
- 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. (1 Tim. 5:19–22; 2 Tim. 4:5; Titus 1:5).
- Priests (presbuteroi) are also known as “presbyters” or “elders.” 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. The term for bishop, episcopos (“overseer”), was also fluid in meaning. Sometimes it designated the overseer of an individual congregation (the priest), sometimes the person who was the overseer of all the congregations in a city or area (the bishop), and sometimes simply the highest-ranking clergyman in the local church.
By the beginning of the second century these terms had achieved the fixed form in which they are used today to designate the three offices whose functions are clearly distinct in the New Testament.
As the following quotations illustrate, the early Church Fathers recognized all three offices and regarded them as essential to the Church’s structure. Especially significant are the letters of Ignatius, Bishop of Antioch, who traveled from his home city to Rome, where he was executed around A.D. 110. On the way he wrote letters to the churches he passed. Each of these churches possessed the same threefold ministry. Without this threefold ministry, Ignatius said, a group cannot be called a church.
Ignatius of Antioch writes:
Clement of Alexandria writes:
Hippolytus writes:
John Chrysostom writes:
Clearly the evidence suggests that bishops and priests are of two orders, not one.
So it makes me wonder where did you initially find the teaching that “the bishops and priests are of one order”. Did you develop the idea yourself, or did you find it somewhere? Because it seems to me like it is factually and historically inaccurate.
