Poking around a bit more:
St. Peter himself said:
"But you are a chosen generation, a kingly priesthood, a holy nation, a purchased people: that you may declare his virtues, who hath called you out of darkness into his marvellous light: "
That doesn’t seem to be a church filled with hierarchy, and almost seems like a priesthood of all believers.
Catholics believe in the priesthood of all believers. But we also know that Jesus established the NT priesthood based on the OT pattern.
In the OT, the structure of the priesthood looked like this:
- Aaron, high priest
- Levites, ministerial priests
- Israel, a nation of priests
We see a similar structure in the NT.
Jesus, Our Eternal High Priest
“Therefore, since we have a great high priest who has passed through the heavens, Jesus the Son of God, let us hold fast our confession.” (Hebrews 4:14)
The Ministerial Priesthood
“But I have written very boldly to you on some points so as to remind you again, because of the grace that was given me from God, to be a minister of Christ Jesus to the Gentiles, ministering as a priest the gospel of God, so that my offering of the Gentiles may become acceptable, sanctified by the Holy Spirit.” (Romans 15:15-16)
The Universal Priesthood of All Believers
“But you are a chosen people, a royal priesthood, a holy nation, a people belonging to God, that you may declare the praises of him who called you out of darkness into his wonderful light.” (1 Peter 2:9)
Additionally, we find that the Apostle Paul himself forgave the sins of others acting in persona Christi or “in the person of Christ” – just as the Catholic Church teaches concerning the sacrament of reconciliation.
2 Corinthians 2:10
10To whom ye forgive any thing, I forgive also: for if I forgave any thing, to whom I forgave it, for your sakes forgave I it in the person of Christ; (KJV)
And to whom you have pardoned any thing, I also. For, what I have pardoned, if I have pardoned any thing, for your sakes have I done it in the person of Christ. (Douay Rheims)
Going further, scripture shows that the ministerial priesthood is also tri-partite.
Bishop, Priest and Deacon

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, that of apostle.
Similarly, on one occasion Peter described himself as a “fellow elder,” [1 Pet. 5:1] even though he, being an apostle, also had a much higher office than that of an ordinary elder.
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 or evangelist), and sometimes simply the highest-ranking clergyman in the local church—who could be an apostle, if one were staying there at the time.
Although the terms “bishop,” “priest,” and “deacon” were somewhat fluid in the apostolic age, by the beginning of the second century they 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.
