[Petrosius]

Rather than priest was originally being l a presbyteral term, meaning senior/old, the word for priest is never used for that office, and only refers to those in sacerdotal function.

False! Old English called them priest precisely because they were presbyters. Those holding the sacerdotal function were called sacerd.

For two thousand years the Catholic Church has been ordaining men to the office of presbyter. Saint Ignatius refers to them at the beginning of the 2nd century. These men have always been called presbyters in both Greek and Latin. Old English called them, and only them, priests. When did these men stop being presbyters?

No, for we are dealing with translating the term for those in the presbuteros/episkopos office as that which is used for those who occupy the sacerdotal office, this being hiereus. In your own official (for America) hiereus is translated as "priest" (as in Heb. 10:11; Rv. 1:6), denoting a sacerdotal class. But which is what RC pastors are distinctively called, not elders (even though the NAB correctly has presbyters in Titus 1:5, while the CRB is inconsistent in this matter). And in function Catholic priests are a separate sacerdotal class, distinctively called "priests," and are also distinctive from NT presbuteros/episkopos (which single office she also splits in two) which are not a separate sacerdotal class.

While "priest" evolved from Late Latin presbyter, it poorly represents it, unlike "elder" and "overseer" for presbuteros/episkopos respectively, and thus "priests" is what most any Bible translates hiereus as, which is the word used distinctively for a separate sacerdotal class, from OT to pagan priests to all believers. But which does not describe NT presbuteros, who are nowhere called hiereus.

Also,

"So far as i know, it was only ca. 200 that the term “priest” started to be applied to the bishop and only still later was it applied to the presbyter... When the eucharist began to be thought of as a sacrifice, the person assigned to preside at the eucharist (bishop and later presbyter) would soon be called a priest, since priests were involved with sacrifice." — Raymond Brown (Sulpician Father and a prominent Biblical scholar), Q 95 Questions and Answers on the Bible, p. 125, with Imprimatur.

Thus it is wrong to use the word that denotes a separate class of sacerdotal priests, which in Greek is hiereus, for NT pastors.
