Why do Catholics call their ministers priests? Is this concept of priests as ministers of the New Covenant of Christ valid and scripturally sound? In my last post, I demonstrated that the English word “priest” derives etymologically from, and was originally a translation of, the Greek word πρεσβύτερος [presbyteros]), attested in the New Testament Scriptures (1 Timothy 3, Titus 1:5,7) and translated in Latin as presbyter, and is thus an appropriate term for the Christian ministry. That the ministers of the Old Testament are also called “priests” in English is mostly the result of a linguistic accident: originally כֹּ֣הֲנִ֔ים [cohenim] in Hebrew, and translated in Greek as ἱερεῖς [hiereis] and Latin as sacerdotes, at some point in the history of transmission these terms became synonymous with Christian priests. The terms became synonymous, apparently, because Christians saw the offices to be synonymous, or at least analogous to one another.

MINISTERS OF THE NEW COVENANT

The New Testament does not refer to Christian ministers as ἱερεῖς or sacerdotes. It is evident that Jesus did not explicitly institute a formal, liturgical priesthood akin to the Aaronic priesthood: He did not command the Apostles to don ephods or breastplates or robes (or albs or chasubles or stoles, as the case may be); He did not formally anoint them as a new priesthood as Aaron and his sons were anointed (Exodus 28). Yet nonetheless, Jesus did appoint the Twelve to have special roles in His ministry, and invested them with His authority, to preach with His voice, to cast out demons, to heal the sick, to forgive sins (Mark 3:13-18, Matthew 10, Luke 9:1-6, John 20:19-23). This was more than just a casual charge to all Christians, but a formal office for which the Apostles were selected and which they saw the need to fill in replacement of Judas (Acts 1:15-26). These Apostles did appoint elders (presbyters) in every church they founded, to carry on their ministry after they departed (Acts 14:23, Titus 1:5). We see the outlines of this ministry in the offices of bishop, priest (presbyter), and deacon, with their roles, duties, and requirements (1 Timothy 3). Thus Scripture demonstrates that Christ did institute, and the Apostles did perpetuate, a new order of ordained Christian ministry, ministers of Christ’s New Covenant (2 Corinthians 3:6).
